Dr. Jenkins sits down for part two of his conversation with Dr. James Emerson of Texas State University. In this episode, they dive into James' research on Crotalus ornatus, the recently reclassified eastern species of Black-tailed Rattlesnake found in the Trans-Pecos region of Texas. Despite its unique status, C. ornatus remains largely understudied. James shares insights from his fieldwork, including movement patterns, habitat use, diet, and more.Connect with James at Texas State University.

This episode is all about the problems rattlesnakes face in the wild. A brilliant new study uncovers whether predatory birds in America are resistant to the toxins of the rattlesnakes they eat, and then we talk about how rattlesnakes deal with the problem of getting water in dry environments. Finally, a beautiful new species of pitviper has been described from Thailand.

Our understanding of the social lives of snakes is evolving at breakneck speed. This week we discuss a new study which has revealed that ball pythons have social behaviour. We also talk about sociality in rattlesnakes, before moving on to some news from the world of milk snake speciation - there may be fewer species than previously thought.

I recorded this episode back in late August while the show was on hiatus, after seeing a post on social media about an effort to conserve and recover the New Mexico Ridgenosed Rattlesnake, Crotalus willardi obscurus.  My ears went up like Scooby Doo and I immediately went in search of someone to talk to about it and as it turns out, Tony Daly-Crews was involved. You may remember my conversation with Tony about the Rattlesnake Conservancy, back in episode 53. Obscurus is the stuff of legend, a snake barely entering the United States and a rattlesnake that a lot of field herpers would like to see.  If you've read any of Carl Kauffeld's books you're familiar with his account of looking for this snake in the Animas mountains of New Mexico. If you haven't, check out the chapter entitled “Follow Me” in the book “Snakes: The Keeper and the Kept” from way back in 1969. You can help the Rattlesnake Conservancy in many ways via their website, savethebuzztails.org, either by donations or through their merch store. You can also participate in some of their events. Thanks for talking with me, Tony!  And thanks for listening everyone! And as always, please keep the comments and suggestions coming, and please take time to rate the show on your podcast platform!

Part 2 of our Timber Rattlesnake episode. If you haven't listened to part 1, go and do that. We'll wait right here for you. The episode was recorded on December 7, 2023 at Hunters Creek County Park in East Aurora, NY.Episode NotesWhen the guys discussed the different types of snake teeth, Steve wondered if the word solenoglyphous, which refers to snakes with two large, hinged fangs (like the Timber Rattlesnake), has any relation to nightshades, which are plants in the genus Solanum. Bill could have cleared it up right away if he had been sharp enough to notice the difference in spelling. Upon getting home and doing some research, he found that the root soleno is Greek, and it means a tube or pipe. This makes sense given that solenoglyphous snakes have large, hollow fangs. The second part of the word - glyphos – means to cut or carve, so solenoglyphous could be taken to mean “hollow fangs that cut or carve”. Incidentally, Bill also tried to look up what Solanum means. He found many circular references – sites that said Solanum means nightshade, and that nightshade means Solanum. The most promising reference he found said that Solanum possibly stems from the Latin word sol, meaning "sun", referring to the nightshades love of sun, maybe? Steve asked if proteroglyphous fangs (the smaller, unhinged fangs in species like the Coral Snake) are hollow. Bill thought they might be, and he was right. A little internet digging led to this blog post that had a handy-dandy cross-section of the different types of snake teeth. Can owls identify venomous snakes? While we couldn't find any studies, or even any general articles, that covered this specific question, we did find an interesting study that looked at venom resistance in a variety of animals. The research “analyzed the molecular resistance against cobra venom and found considerable differences in resistance between animas groups.” It showed that several mammal species, such as the Honey Badger and the Asian Mongoose, independently evolved resistance to cobra venom, but the snake-eating bird species looked at showed no resistance. The study's authors hypothesized that "…the resistance is redundant: There is no selection pressure for it. Birds have feathers, scaly legs, excellent vision, are very intelligent, and are very agile. The snakes don't stand a chance against all these adaptations, so birds just don't need to be resistant." So, while we don't know if owls can ID venomous snakes, at least one team of researchers feels that snake-eating birds are such bad-ass hunters, with so many tools in their evolutionary toolbox, that they wouldn't even need to tell the difference between venomous and nonvenomous snakes. And that answers another question the guys asked: Do Honey Badgers eat venomous critters? They do! And the story of how is shared in this great article from Slate. Our favorite quote: “Evolving to withstand snake venom [and so be able to eat a venomous snake] is like being the only person at a party who can eat the extra-hot salsa: You get it all to yourself. Plus…this means the honey badger gets to hunt fairly slow-moving prey with only one pointy end, rather than fast prey with one pointy end plus four sets of claws.”Steve was correct in calling our Bill for referring to the England as United Kingdom during the USA's colonial period. The UK did not form until 1801, when the Kingdom of Ireland joined with Scotland, England, and Wales.

Love ‘em or hate ‘em, we wager you'll enjoy this dive into the shiny (not slimy) world of rattlesnakes. This episode, the guys take a close look (but not too close) at the Timber Rattlesnake (Crotalus horridus), trying to show how it's not out to kill you and also finding out how it ended up on the “Don't Tread On Me” flag. Plus, they introduce the newest field guide, Daniel! The episode was recorded on December 7, 2023 at Hunters Creek County Park in East Aurora, NY.Episode NotesOne intriguing question that came up was, “If rattlesnakes that rattle call attention to themselves and get killed by humans, does this mean we're inadvertently selecting for rattlesnakes that don't rattle and creating populations of silent rattlers?” It's an idea that sounds logical, but, as the guys have discovered on many other occasions, that doesn't mean it's true. After some digging through a variety of sources, the guys could find zero research-based evidence supporting the idea of this phenomenon. There are news stories that promote it, but all the ones that do seem to base their info on anecdotal accounts. The most interesting source - and the one the guys found to be the most skeptical (in the best sense of the word) - was from Rattlesnake Solutions LLC, an Arizona-based rattlesnake removal and consulting service. This is ironic because Bill went out of his way during the episode to caution listeners to be wary of such sites, but this one seems to genuinely want to not only share solid info about rattlesnakes but also to combat misinformation. In a post called, “Are rattlesnakes evolving to rattle less, or losing their rattles?”, they explained:Rattlesnakes don't often rattle in the wild, even when there's someone looking at them. This is a great example of confirmation bias. If you hear that rattlesnakes aren't rattling any longer, and you then see a rattlesnake just sitting there and not rattling, this can serve as confirmation that the rumors are true. You then tell others this is the case, having first-hand experience on the matter, comment on Facebook, etc. Just like that, you've become the latest node in the spread of nonsense without realizing it.This can be even more confusing for long-term hikers with a lot of experience, who report seeing this phenomenon over time (decades even), where rattlesnakes used to rattle but now most of the rattlesnakes they see don't: therefore the myth is true. What these anecdotes really look like is something much more simple to explain. Over the years, these people have simply become better at seeing rattlesnakes, and peaceful sightings of rattlesnakes just sitting silent, as they usually do, become more frequent.Check out their full post for more information.Do any snake species have eyelids? As far as we could find, no. Instead, snakes have a brille; a transparent, disc-shaped, immobile scale that covers the eye.Is Pennsylvania one of the “biggest hunting states”? During the episode, Steve asked if he was right thinking that Pennsylvania was one of the biggest hunting states, and Bill confirmed it, pretending that he had some knowledge of whether this was true or not. He looked into it after recording and found this listing of states, ranked according to the number of hunters. Turns out Pennsylvania is #23 (Wyoming is number 1), so Bill was just straight-up wrong. At what point does inactivity cross the line and become brumation? This was a question to which we could not find a definitive answer. From reading several articles, the best explanation the guys could cobble together was that brumation is typically long-term, seasonal, and is something animals prepare for by eating more food, while inactivity is short-term and sporadic. But take that last sentence with a grain of salt; like with hibernation, brumation seems to occur on a spectrum that can vary with species and conditions. More info here.Does the Timber Rattlesnake breeding season differ from north to south? The guys could find no definitive answer for this either, but by looking at descriptions of Timber Rattlesnake breeding seasons state-by-state, they did notice differences. For example, in their home state of NY, it was noted that Timbers breed from early summer (June/July) to early autumn (Sept/Oct), while the National Forest Service listed the Timber's breeding season in Florida as August through October. So, there appears to be a later start to the breeding season further south, and the breeding season appears shorter there, as well. Are sharks viviparous or ovoviviparous? Turns out that sharks are similar to snakes in that some lay eggs (oviparous), some give birth to live young (viviparous), and some have eggs that hatch in the body (ovoviviparous). And, just to make it more complicated, there are some records of sharks reproducing asexually. Finally, Daniel wondered what happens to the eggs in ovoviviparous animals (the ones who have eggs hatching inside their bodies). Are the eggshells expelled, absorbed, or what? This was a question the guys could not find an answer to, so if any listeners out there can help them out, please get in touch!Please comment below if you notice any mistakes or unanswered questions in the episode.Episode LinksWild Snake Education and Discussion Group's article about Timber Rattlesnakes And here's a link to their Facebook group, too.Mary Holland's blog post on vivipary, ovipary, and ovovivipary, and a second site that provided more in-depth info: Everyone's Talking About....Ovoviviparity, Oviparity, and ViviparityCheck out the National Park Service's handy-dandy breakdown of snake dentitionTimber Rattlesnakes are intertwined with US history.

Summary: Even though rattlesnakes are only found in the New World, there are a plethora of cool species. Join Kiersten as she take a few close up looks at some wicked cool rattlesnakes.   For my hearing impaired listeners, a complete transcript of this podcast follows the show notes on Podbean   Show Notes: America's Snake: The Rise and Fall of the Timber Rattlesnake by Ted Levin Rattlesnake: Portrait of a Predator by Manny Russo https://www.savethebuzztails.org https://waterlandlife.org https://www.fws.gov/specis/eastern-massasauga https://www.desertmuseum.org https://www.floridamuseum.ufl.edu Music written and performed by Katherine Camp   Transcript  Kiersten - This is Ten Things I Like About…a ten minute, ten episode podcast about unknown or misunderstood wildlife. (Piano music stops) Welcome to Ten Things I Like About… I'm Kiersten, your host, and this is a podcast about misunderstood or unknown creatures in nature. Some we'll find right out side our doors and some are continents away but all are fascinating.  This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won't regret it. This episode continues rattlesnakes and the second thing I like about this astounding reptile is the variety of species alive today. Today we'll start off with a little taxonomy. As a reminder taxonomy is the scientific classification of living creatures. It is a way of grouping plants and animals into families for easier study. Rattlesnake classification is as follows: Kingdom: Animalia (this means it's an animal), Phylum: Chordata (roughly speaking they have a backbone), Class Reptilia (they are reptiles), Order Squamata (this contains lizards and snakes), Suborder Serpentes (snakes), Family Viperidae (a group of venomous snakes called vipers including rattlesnakes), Subfamily Crotalinae and two different genera including Crotalus and Sistrurus. Don't worry there won't be a test at the end of this episode! Currently there are 32 accepted species of rattlesnake with 83 subspecies. Upon the advent of DNA testing, this number has fluctuated as scientists discover more information about family relatedness based on genetics versus physical characteristics or behavior. Basically what I'm saying is that this number may be correct today but different tomorrow. The majority of species are found in Genus Crotalus and only three are classified in Sistrurus. There is one outstanding physical characteristic that separates the two genera. The scales on the top of the head of Genus Crotalus will typically be small and similarly shaped, while Genus Sistrurus will have a less uniform group of nine large scales on the crown of the head. There are always exceptions to the rule in Nature so this description is not a hard and fast rule, but a more general rule.  Before we look at some specific rattlesnakes more closely, let's discuss where rattlesnakes can be found on the planet. Rattlesnakes are a New World animal which means they are found only in North, Central, or South America. They can be found from southern Canada to central Argentina with the most variety found in the southwestern United States and northern Mexico. A few are found on islands in the Caribbean such as Aruba. The habitats they are found in vary from desert to semi-arid desert to prairie to timber woodlands. They did not evolve to tolerate rainforest habitat. Rattlesnakes can be found in areas that have a cold winter as long as they have dens to hibernate in to keep from freezing to death. In areas that are warmer, they have adapted to living near human suburbs because they are attracted to the mice and rats that are attracted to us. In areas that are colder and the need for a denning sit that remains undisturbed through the winter is crucial, they are struggling to survive.  Now that we know a little about rattlesnake taxonomy and where we can find them, let's take a closer look at a few individual species. One of the most well known rattlesnakes is the Diamondback. This snake is an icon of the wild west of the United States but there is an Eastern Diamondback as well as a Western Diamondback. The eastern Diamondback is native to the southeastern United States and can be found in the pinelands of Florida, the coastal plains of North Carolina and southern Mississippi through eastern Louisiana. The western diamondback is found throughout the western portion of the United States including Arizona, California, New Mexico, Oklahoma, Texas, and northern Mexico. The two snakes are separate species in Genus Crotalus. The eastern Diamondback is Crotalus adamanteus and the western diamondback is Crotalus  atrox. As their name suggests they have large diamond shaped patterning on their back. It begins behind the head and travels down to the tail. The diamond shapes will be darker than the base color of the snakes. The eastern diamondback is typically brown or gray with the base color darkening toward the tail where dark bands appear just before the rattle. The western diamondback base color ranges from light brown to dark brown to reddish brown depending on habitat with bright white and black stripping just before the rattle. Both diamondback snakes are some of the longest and heaviest rattlesnakes alive today with adults ranging from 2 1/2 feet to 7 1/2 feet.  Let's look at one of the snakes in Genus Sistrurus. Sistrurus catenatus, the eastern Massasauga is a small but thick bodied rattlesnake found in the eastern portions of North America. This 1 1/2 foot to 2 1/2 foot snake is found in the northern midwest United States and Ontario, Canada. Their current range is much smaller than their historic range. They tend to favor shallow wetlands with surrounding upland areas that they use for hunting, breeding, and hibernating. Coloration varies from gray to light brown, but some black individuals have been seen. The splotches that travel down the back are generally dark in color and resemble a colored in number eight. They will also have rows of smaller blotches down the sides of the body. The tail has a small rattle which sounds like the buzz of an insect when they are agitated.  Let's travel down into South America and take a look at the only rattlesnakes found there. The South American Rattlesnake or Crotalus durissus  is found in the Cerrado ecoregion of southern Brazil, Uruguay, Paraguay and northern Argentina. In Portuguese this snake is called “cascavel”. The cascavel typically makes its home in grasslands and savanna habitats although they are occasionally found in dry forests and open clearings in jungles. Adults range in size from 2 1/2 feet to 6 feet in length. Base colors vary widely from yellow  to light brown to reddish to dark brown or even gray. Some reports of greenish tinted specimens have seen seen near forested areas. They have two stripes that run from the top of the head down the neck that fade as the body gets larger. Diamond shaped patterning flows down the rest of the body terminating at the tail where the rattle begins. Like most other rattlesnakes they are a heavy bodied snake and they have one of the widest ranges of any rattlesnake. There are several subspecies of Crotalus durissus.  We're going to look at one more species in depth and this is the one rattlesnake that doesn't have a functioning rattle. That's right, this rattlesnake doesn't have a rattle. The Santa Catalina Island rattlesnake, Crotalus catalinensis, is genetically a rattlesnake but after years and years of living on an island they have lost their rattle. They do have the button, the base of rattle, but it comes off with every shed preventing a rattle from developing. They are native to Isla Santa Catalina in the Gulf of California. Adults range in size from 2 feet to 2 3/4 feet. They can be found almost anywhere on the island and unlike other rattlesnake species they are often found hunting in trees. They are the most arboreal rattlesnake of any rattlesnake species. This may explain why they are more slender than any other rattlesnakes, as well. This is a lovely little rattlesnake with a grayish brown base color and large white-bordered diamond blotches along the back. The tail terminates in black and gray striping reminiscent of diamondback rattlesnake tails. These snakes can be a very pale gray with light brown blotches creating a stunningly beautiful pattern.   That is all for this episode of rattlesnakes. There are so many more cool species of rattlesnake but I had to restrain myself to my ten minutes limit. Thanks for joining me because the variety of species alive today is my second favorite thing about rattlesnakes.    If you're enjoying this podcast please recommend me to friends and family and take a moment to give me a rating on whatever platform your listening. It will help me reach more listeners and give the animals I talk about an even better chance at change.    Join me next week for another episode about rattlesnakes.     (Piano Music plays)  This has been an episode of Ten Things I like About with Kiersten and Company.

The timber rattlesnake, canebrake rattlesnake, or banded rattlesnake (Crotalus horridus) is a species of pit viper endemic to eastern North America. Like all other pit vipers, it is venomous, and this species is sometimes highly venomous. This is the only rattlesnake species in most of the populous Northeastern United States and is second only to its relatives to the west, the prairie rattlesnake, as the most northerly distributed venomous snake in North America.

The timber rattlesnake, canebrake rattlesnake, or banded rattlesnake (Crotalus horridus) is a species of venomous, sometimes highly venomous, pit viper endemic to eastern North America. This is the only rattlesnake species in most of the populous Northeastern United States and is second only to its relatives to the west, the prairie rattlesnake, as the most northerly distributed venomous snake in North America.[8][9] No subspecies are currently recognized.

Venoms are complex, and researchers are constantly discovering new intriguing uses. But this episode we look at a fascinating new venom use for the snakes themselves.

Jeff:  Welcome back to Emplify, the podcast corollary to EB Medicine’s Emergency Medicine Practice. I’m Jeff Nusbaum, and I’m back with my co-host, Nachi Gupta and we’ll be taking you through the September 2018 issue of Emergency Medicine Practice - Emergency Department Management of North American Snake envenomations. Nachi: Although this isn’t something we encountered too frequently – it does seem like I’ve been hearing more about snake bites in the recent months. Jeff: I actually flew someone just the other day because the local ED ran out of CroFab after an envenomation in Western PA. Nachi: Yeah, this is definitely more than “just a boards topic,” and it’s really important to know about in those rare circumstances. In terms of incidence, there are actually about 10,000 ED visits in the US for snake bites each year, and 1/3 of these involve venomous species. Jeff:  That’s a good teaser, so let’s start by recognizing this month’s team – the two authors, Dr. Sheikh, a medical toxicologist, and Patrick Leffers, a pharmD, and emergency medicine and clinical toxicology fellow. Both are at the University of Florida Jacksonville, and they reviewed a total of 120 articles from 2006-2017, in addition to reviews from both Cochrane and Dare. Nachi: And don’t forget our peer reviewers this month, Dr. Daniel Sessions, a medical toxicologist working at the South Texas Poison Center, and our very own editor-in-chief, Dr. Andy Jagoda, who is also Chair of the Department of Emergency Medicine at Mount Sinai in New York City. Jeff: What a team! But, let’s get back to the snakes. As some background, from 2006-2015 there were almost 66,000 reported snake exposures and 31 deaths from snake envenomation in the US.  Of course, this number likely underestimates the true total. Nachi: And there are two key subfamilies of venomous snakes to be aware of – the Crotalinae – or pit vipers – which includes rattlesnakes, copperheads, and water moccasins; and the Elapidae – of which you really only need to know about the coral snake. Jeff:  And while those are the only two NATIVE snake subfamilies to be acutely aware of, don’t forget that exotic snakes, which are shockingly popular pets -- they can also cause significant morbidity and mortality. Nachi:  Oh, and one other quick note before we get into the epidemiology – most of the recommendations this month come from expert opinion, as high quality RCTs are obviously difficult.  In addition, many of the studies were based in other countries, where the snakes, the anti-venoms and their availability, and the general healthcare systems are different from those that most of us work in. Jeff:  Unless we have listeners abroad? Do we have listeners in other countries? Nachi: Oh we definitely do... but we are going to be a bit biased towards US envenomation today. In any case, venomous snake bites occur most frequently in men aged 18 to 49 during warmer months with provoked bites occurring more frequently in the upper extremities and unprovoked bites in the lower extremities. Jeff:  In one study of poison center data from the last decade, nearly half of all victims of snake bites were victims of unknown type snakes.  However, of those that were known, copperheads were the most common, while rattlesnakes caused the most fatalities – 19 of 31 in this dataset. Nachi:  In a separate study of snake bites in the early 2000s, 32% of exposures were from venomous snakes and 59% of those resulted in admission. That’s remarkably high. Jeff:  Snake bite severity depends on several key factors: the amount of venom, the composition of the venom, the body size of the bite victim, the victim's clothing, the size of the bite, comorbid conditions, and the timing and quality of medical care the victim receives. Nachi:  To be a bit more specific - First, the amount of venom will depend on the species of snake, with variations even occurring within the same species.  Secondly, while there is a correlation between rattlesnake size and bite severity, there is much more at play.  Some snakes can even vary the amount of venom based on threat risk – with defensive bites having different profiles than bites to strike prey. Jeff: I found it pretty interesting that  an estimated 10-25% of pit viper bites are considered dry bites, that is, ones in which no venom is released. Nachi:  Right, this is just one reason why all victims shouldn’t immediately get anti-venom, but we’ll get there. Jeff:  We definitely will.  As we already stated – venom composition varies greatly.  Pit vipers produce a predominantly hemotoxic venom.  Systemic effects include tachycardia, tachypnea, hypotension, nausea, vomiting, weakness, and diaphoresis.  Neurotoxicity is rare and is usually due to inter-breeding between species. Nachi:  While rattlesnake bites are associated with higher morbidity and mortality, the more common copperhead bites typically only cause local tissue effects.  More serious systemic findings such as coagulopathy and respiratory failure have been reported though. Jeff:  So that’s a solid background to get us started.  Let’s talk about the individual snakes.  Why don’t you start with the crotalinae family – aka the pit vipers. Nachi:  Sure – the crotalinae includes rattlesnakes, cottonmouths (also known as water moccasins), and copperheads.  These make up the vast majority of reports to the poison centers.  They can be identified by their heat sensing pits located behind their nostrils (hence pit vipers).  As a general rule, you can also identify the venomous snakes by their triangular or spade-like head, elliptical pupils, and hollow retractable fangs. Jeff:  wait, so you want me to walk up to the snake and ask to see if their fangs retract… yea, no thanks. Nachi: Haha, of course not, I’m just giving you some of the general principles here. In contrast, non-venomous pit vipers have rounded heads, round pupils, a double row of vertical scales, and they lack fangs. Jeff: In terms of location, rattlesnakes are found in all states but Hawaii, and cottonmouths and copperheads are distributed mostly throughout the southern and southeastern states, with copperheads also extending further north, even into Massachusetts. Nachi: Moving on to the Elapidae –  there are 3 species of coral snakes, only two of which you need to know about, Micrurus fulvius fulvius or the eastern coral snake and Micrurus tener or the Texas coral snake.  Of the two, the eastern or Micrurus fulvius fulvius produces more potent venom. Jeff:  As you may have guessed by their names, the eastern coral snake is found in the southeastern united states, specifically, east of the Mississippi -- whereas the Texas coral snake lives west of the Mississippi. Nachi:  Venomous North American coral snakes can be recognized by the red and yellow bands around their bodies whereas their nonvenomous counterparts can be recognized by their characteristic black band between the red and yellow bands. I’m sure you’ve heard the popular mnemonic for this… Red touch yellow kill a fellow, red touch black, venom lack. Jeff:  I have heard that one, and it’s not a bad mnemonic. Just remember that this is more of a guideline than a rule, as it doesn’t always hold true. Nachi: Coral snakes also tend to chew rather than bite thanks to their short, fixed, hollow fangs.  Locally, bites can lead to muscle destruction thanks to a certain myotoxin.  Systemic signs of infection include nausea, vomiting, abdominal pain, and dizziness.  Jeff: The venom also contains a neurotoxin which can lead to diplopia, difficulty swallowing and speaking and generalized weakness. Nachi: Complicating matters even further, the onset of these symptoms may be delayed for many hours. Jeff:  Alright, so I think that about wraps up the background.  Let’s move on to the meat and potatoes of this article, starting with the differential. Nachi:  For differential this month, we are really focusing on differentiating a venomous snake from a non-venomous one. Jeff: Oh yeah, this is where you want us to ask the snake if it can retract its fangs, right? Nachi: Ha very funny – Although the type of snake may be obvious if the patient owns the snake, for most cases you see in the ED, the type of snake won’t be clear. Try to get a description of the snake and consider your local geography. Some patients may even bring the snake in with them. Jeff: yea, no thanks. As for prehospital care, it’s actually pretty interesting stuff as recommendations have changed many times.  You may have heard of the recommendations for incision / excision, use of venom extraction devices, tourniquets, chill methods and even electroshock therapy – well these methods are all OUT. Nachi:  Not only are they out, they actually worsen outcomes, so definitely don’t pursue any of them.  Instead,  since no treatment has been shown to improve outcome, you should prioritize prompt transport. Jeff: And while we definitely don’t want to encourage ill-advised attempts at capturing the snake, taking pictures at a distance may be helpful in identifying it.  Oh and the authors do note- pretty terrifying stuff coming up here so brace yourself - even if the snake is dead the bite reflex is still intact… Nachi: And that’s why I work in city hospitals… Jeff:  There’s also a bit of controversy here with regards to pressure immobilization, which is definitely something I thought we were supposed to do in the prehospital setting. Apparently in other countries, like Australia, prehospital providers frequently employ pressure immobilization – that is, wrapping bandages proximally up a splinted limb to impede lymphatic toxin spread. Nachi:  Right, but in Australia, not only are the snakes more venomous but the hospital transport distances are much longer, so, basically they sacrifice the limb to potentially save a life.  In the US, with our current indigenous snake population and the relatively short transport distances, this isn’t justified at all! Jeff:  Take home: based on the current literature, the American College of Medical Toxicology, other experts, and Drs. Sheikh and Leffers recommend against pressure immobilization in lieu of prompt patient transport to definitive treatment. Nachi:  Good to know – alright so now we have the patient in the emergency department, let’s begin ED care.  As always – IV, O2, Monitor including end tidal CO2 if you suspect a neurotoxic or exotic snake bite.  Of course, avoid using the affected limbs for vitals… Jeff: If not done already, remove any constrictive clothing or jewelry and mark the leading edge of pain, edema, and erythema both above and below the bite.  If EMS has placed bandages, leave them in place until antivenom and resuscitative equipment is ready. Nachi:  And definitely involve the poison control center or a medical toxicology service early as they are an amazing resource. It’s an easy number to remember.. 1-800-222-1222. If you just type “poison control center” into google, that number will come up immediately. Jeff: Hypotension should be treated with isotonic fluids and, as usual, anaphylaxis should be treated with the usual cocktail of antihistamines and epinephrine at first IM and then via infusion if refractory. Note that antivenom will NOT reverse anaphylaxis on its own. Nachi:  When eliciting a history, there are a number of important factors to look out for, including – time and location of the bite, description of the snake, tetanus status, comorbid conditions, medications and allergies, any systemic or neurologic symptoms, muscle cramps, perioral tingling or numbness, metallic taste, history of previous snakebites and any reactions to previous envenomation or antivenom treatment. Jeff: Moving on to the physical exam, when examining the wound, look specifically for local tissue effects which occur in over 90% of patients after pit viper envenomations.  In such cases, you would expect pain, erythema, swelling, tenderness, and myonecrosis beginning at the wound site and then spreading via the lymphatic system. Nachi:  In addition, specifically with pit viper envenomations, monitor the patient for possible compartment syndrome as the venom can lead to local tissue destruction, increased cell permeability, third spacing of fluids, and bleeding.  And remember that while the local compartment may be hypertensive, the patient may also have systemic hypotension. Jeff: Just to reiterate what I said before – hypotension may indicate severe anaphylaxis and its not necessarily just due to third spacing.  Regardless, the treatment is the same – epinephrine. Nachi:  Good point, but let’s focus on compartment syndrome for a minute.  True compartment syndrome is actually quite rare --- its really subcutaneous hypertension with preservation of otherwise normal compartment pressures that you’re most likely to see.  Compartment syndrome should therefore only be diagnosed by actual compartment measurements and not just the exam.  However, if you are dealing with compartments that can’t be measured, like in the fingers, you’re only choice is to be guided by the exam… Jeff:  Risk factors for compartment syndrome in the setting of a snake bite include envenomations in small children, involvement of digits, application of ice or cold packs, and delayed or inadequate antivenom administration. Nachi: In terms of respiratory effects of envenomations – they aren’t common.  Both bites to the head or neck and neurotoxin containing venom are potential causes. In the setting of respiratory failure, be prepared with advanced airway maneuvers like nasotracheal intubation or cricothyroidotomy. Antivenom will not reverse respiratory failure. Jeff: Neurologic effects may be present upon arrival but may also be delayed up to 12 hours in the case of eastern coral snake bites. Nachi: It’s noteworthy that in one study of almost 400 eastern coral snake exposures, the onset of systemic symptoms occurred on average 5.6 hours after the bite.  So definitely remember that repeat exams and observation will be tremendously important. Jeff:  The actual neurologic symptoms to look for depend on the snake.  Coral snake venom can produce a descending flaccid paralysis characterized by motor weakness, especially of the cranial nerves.  Similarly pit vipers, especially the Mojave rattlesnake, have also been associated with muscular weakness of the cranial nerves and even respiratory insufficiency. Nachi:  Pit viper envenomation can also lead to myokymia which is repetitive small muscle fasciculations.  Unfortunately, this myokymia may not respond to antivenom administration and myokymia of the chest well and torso can necessitate intubation in extreme cases.  Both myokymia and myonecrosis may lead to rhabdo in the case of significant envenomations. Jeff:  Pit viper envenomation can also cause hematologic effects.  Fibrinolysis and platelet consumption at the bit site can lead to decreased fibrinogen and thrombocytopenia.  In severe cases this can lead to systemic bleeding and even hemorrhagic shock.  Those on anticoagulants and anti-platelet agents are at increased risk. Nachi:  Dermal effects such as edema, ecchymosis, bullae, and bleeding are not uncommon, but up to 50% of coral snake bite victims may have none of these. Jeff:  And to round out this section – just be aware that rare effects such as osteonecrosis, ischemic stroke, massive PE, and septic shock have all been reported. Nachi: Let’s move on to diagnostic studies.  Most patients require a CBC, coags, and a fibrinogen concentration.  Those with systemic toxicity should also have their electroyltes, CPK, creatinine, glucose, and urine tested. Jeff:  And while the data is somewhat mixed, one study suggests that all patients with pit viper envenomations need their coags checked, not just those with severe symptoms as in one series nearly 90% of patients had missed coagulation abnormalities.  The clinical consequences of this aren’t clearly explained, so the authors don’t make a specific recommendation. Nachi:  In terms of imaging, a chest x-ray should be obtained in those with respiratory symptoms and ultrasound may even have an expanding role here for tracking edema, looking for fluid collections, and assessing deep muscle compartments and vascular flow. Jeff: I feel like we should get some entry music for every ultrasound reference because it seems to make its way into just about every episode. Nachi: What would it sound like? You bring this up every month. I’ll look into something for a future episode. If any of our listeners have a suggestion, shoot us an e-mail at emplify@ebmedicine.net. In terms of monitoring and observation, this is important, ALL patients with suspected pit viper envenomations should be observed for 8-12 hours with the leading edge marked every 15-30 minutes. Jeff:  In addition, serial diagnostic testing may also be needed as such changes will be used to guide treatment.  In those with systemic symptoms, lab testing will be required every 4-6 hours prior to discharge. Nachi:  Before we move onto treatment – let me quickly mention grading.  There is no universal grading system.  The snakebite severity score, the minimum-moderate-severe score, and grade 1-4 score which consider symptoms, exam findings, and lab abnormalities have all been studied.  None have been validated and none track changes, so the authors recommend relying on severity of symptoms and progression of symptoms to guide treatment. Jeff:  The crux of treatment for pit viper envenomations is with supportive care and anti-venom. Nachi:  FabAV or CroFab is the antivenom of choice for pit viper envenomations.  This antivenom is made from extracting the Fab portion of anti-venom antibodies from envenomated sheep and processing them with papain. Jeff:  Since the sheep are injected with venom from the western diamondback, eastern diamondback and Mojave rattlesnake as well as the cottonmouth, the FabAV is most effective against venom from these snakes, however it does have cross reactivity to other immunologically similar venoms. Nachi:  Indications for FabAV include a more than minimal local swelling, rapid progression of swelling, swelling crossing a major joint, evidence of hemotoxicity, signs of systemic toxicity including hemodynamic compromise, neuromuscular toxicity, and late or recurrent new-onset coagulopathy. Jeff:  Initially, dose FabAV as a bolus of 4-6 vials, IV.  With life threatening envenomations or those with cardiovascular collapse, double the starting dose to 8-12 vials.  The goal is arresting progression, improvement in coagulation abnormalities, and resolution of systemic symptoms. Nachi: Although FabAV will reduce the duration and severity of symptoms and lab abnormalities, it will not reverse tissue necrosis and may not reverse neurologic effects. Jeff:  Once the symptoms have been controlled after the bolus dose or a second bolus dose, maintenance dosing of 2 vials every 6 hours for 3 doses is recommended to prevent recurrence. Nachi:  So to reiterate.  4-6 vial bolus to start, doubled in severe cases and then 2 vials every 6 hours for 18 hours after that. Jeff:  You got it. Nachi:  And like most, maybe all medicines, there are side effects and contraindications to be aware of.  Hypersensitivity reactions and serum sickness to FabAV have been reported as 8% and 13% respectively.   Most are mild and can be treated with your standard bundle of steroids, antihistamines, fluids and epi. Jeff:  Risk factors for developing allergic reactions to FabAV include  a known allergy to papaya, papain, chymopapin, pineapple enzyme bromelain, and previous allergic reaction to FabAV. Nachi:  Although FabAV isn’t produced using copperhead venom, it may be effective in severe envenomations and in one study, FabAV reduced limb disability compared to placebo. Jeff:  Therefore, the authors very reasonably advise that you should use the patient’s clinical picture and individual factors rather than the snake species to guide your treatment. Nachi:  Interestingly, compartment syndrome should be treated with the initial 4-6 vial dose of antivenom and not necessarily a fasciotomy.  Fasciotomies have not been shown to improve outcomes and are reserved only for those failing anti-venom treatment. Jeff:  The reason for this is that antivenom may reduce tissue pressures obviating the need for fasciotomy.  In addition, fasciotomy wouldn’t affect muscle necrosis that is occurring so fascia removal really doesn’t solve anything. Nachi:  And just as anti-venom can be used to treat elevated compartment pressures, it can also be used to treat coagulopathy. Jeff:  Blood products should be used for those who are actively bleeding or severely anemic as venom does not discriminate and will destroy whatever blood it comes across. Nachi:  Recurrent and late onset coagulopathy after FabAV treatment has also been well described.   Although not exactly clear why, some speculate that it occurs for one of 4 reasons. 1) because the half life of FabAV is shorter than that of the venom, or 2) because the venom is initially stored in the soft tissues and then slowly released over time or 3) because the venom has a late onset component, or lastly, 4) there is delayed dissociation of the venom-antivenom complexes.  Regardless of the mechanism, late onset coagulopathy can be treated with FabAV. Jeff:  Luckily, bleeding associated with coagulopathy and bleeding associated with late onset coagulopathy are both extremely rare.   Nachi:  Moving on to coral snakes.  Coral snake bites should be treated with NACSA or North American Coral Snake anti-venom.  This antivenom halts or at least limits the progression of muscle paralysis and shortens the clinical course. Jeff:  Most experts recommend NACSA treatment with the first signs of systemic toxicity and not for all comers.  This recommendation is backed by the literature as in one observational study those treated with prophylactic NACSA did less favorably as compared to those who got it only after symptoms onset.  This is probably because NACSA doesn’t reverse neuromuscular weakness and only limits progression. Nachi:  And it’s not like you are just sitting by and watching while doing nothing – focus your initial treatment on wound care, pain control, and then observation for the development of systemic symptoms.  The exact length of observation will depend on the snake, but should be somewhere between 8 and 24h. Jeff:  As for dosing – the initial NACSA dose is 3-5 vials IV for both peds and adults with a repeat dose if the initial symptoms don’t improve. Nachi: Side effects and adverse reactions occur somewhere between 8-11% of the time with dermal reactions being most common and anaphylaxis being the most severe. Jeff: There is also one last anti-venom to be aware of – Coralmyn, for coral snake envenomations.  Coralmyn is a polyclonal antivenom F(ab’)2 coral snake antivenom, developed because the current lot of NACSA has technically expired although the date has been extended numerous times.  It’s currently in a phase 3 trial, so keep your eyes out. Nachi:  Other non-antivenom treatments that have been tested include acetylcholinesterase inhibitors and trypsin at the bite site – both should be considered experimental at this point. Jeff:  To wrap up the treatment section, let’s talk exotic snakes.  You may recall from the intro that these have a higher morbidity and mortality compared to native species. Nachi:  You will have to rely on your local poison control center or toxicologist for advice and you may even need to turn to the zoo or aquarium for antivenom, if it exists at all.  Patients with bites from exotic snakes should be monitored, likely in the ICU, for up to 24 hours as toxicity from some venom may have a delayed onset of up to 20 hours. Jeff:  Scary stuff, hopefully the patient knows which type of exotic snake they own and you don’t have to sort through a million google images to try to get to the bottom of this.  Anyway, there are 3 special populations to discuss.  First are pregnant patients. Nachi:  The authors cite a 1.4% incidence of snake bites in pregnant patients.  They note that this is low, but from my perspective, this seems shockingly high – why would a pregnant person ever get anywhere near a snake, seems just ill advised… Jeff:  haha, true.   But regardless, treatment is the same with antivenom as needed for all the same indications.  With fetal demise rates as high as 30%, in addition to maternal monitoring, the fetus should also be monitored. Nachi:  That number may seem high, but keep in mind that that’s from studies in other countries with more venomous snakes, so it’s likely to be lower in the US.  But the point remains, that antivenom is generally recommended to be given if the mother has indications for treatment, as poor fetal outcome is tied directly to the severity of envenomation in the mother. Jeff: Continuing right along, the next special population to discuss are pediatric patients.  Because dosing is based on the amount of venom delivered and not on patient specific factors, dosing is the same for peds and adults. Nachi:  How rare – so few meds seem to be the same for peds and adults.  The last population to discuss are anticoagulated patients.  Patients on antiplatelet or anti-coagulants are at increased risk of bleeding after pit viper envenomations and therefore should have their coags checked every 2 days following the last dose of FabAV. Jeff:  I think we’ve at least mentioned most of this months controversies, but it’s probably worth quickly reviewing them since they mostly dispel common myths. Nachi:  Good idea.  Incision and suction of snake bites is nearly universally not recommended. Jeff:  In the absence of ischemia, fasciotomy for snake bites is not recommended, even with elevated compartment pressures.  Instead treat compartment syndrome with anti-venom and save the fasciotomy for true cases of ischemia refractory to antivenom. Nachi:  With a known or suspected coral snake envenomation, due to shortages of NACSA, wait until the patient develops symptoms instead of empirically treating all bite victims. Jeff:  Maintenance dosing of FabAV continues to be debated.  The manufacturer recommends 2 doses every 6 hours for 3 doses while some experts recommend only maintenance dosing as needed.  It’s therefore probably safest to punt this to whatever poison control center or toxicologist you speak with. Nachi:  I feel like we are plugging the poison center a lot, but it’s such a good free, and usually very nice consult to have on your team. Jeff: Nice consultant – what a win!  Moving on to the cutting edge.  There is a new Crotalidae antivenom called Crotalidae Immune F(ab’)2 or, more simply, Anavip.  It should be available in the next few months.  The dosing will be 10 vials up front over 60 minutes followed by an additional 10 vials if the symptoms having been controlled.  4 more vials may be given for symptom recurrence.  Patients must be observed for a minimum of 18 hours after initial control of symptoms. Nachi: This would be a really nice development as Anavip has a longer half life and therefore should reduce the rates of late coagulopathy and decrease the need for maintenance dosing, follow up, and repeating coags. Jeff:  And finally, like we mentioned before, injection of the trypsin has been tried as a bridge to antivenom, as has carbon monoxide, which may mediate degradation of fibrinogen dependent coagulation. Nachi:  Alright, so let’s talk about the disposition next. Victims of pit viper envenomations should be monitored for 8-12 hours from the time of the bite.  They will need baseline labs and repeat testing ever 4-6 hours.  IF there is no progression of the symptoms and repeat testing is normal, the patient can be discharged. Jeff: Victims of coral snake bites should be admitted and observed for 12-24 hours regardless of symptoms. Nachi: Victims of rattle snake envenomations who initially develop hematologic abnormalities and are treated with FabAV should have repeat testing done in 2-4 days and 5-7 days. Jeff:  Wounds should also be closely followed to avoid complications and long term disfigurement and disability.  PT/OT may be necessary as well. Nachi:  Perfect, let’s round this episodes out with a review of the key points and clinical pearls from this month’s issue. There are about 10,000 ED visits in the US for snake bites each year, and 1/3 of these involve venomous species. Pit vipers produce a predominantly hemotoxic venom. Both local and systemic effects can occur. Systemic effects include tachycardia, tachypnea, hypotension, nausea, vomiting, weakness, and diaphoresis. In general, venomous snakes have a triangular or spade-like head, elliptical pupils, and hollow retractable fangs. In contrast, non-venomous snakes have a rounded head, round pupils, lack fangs, and can have a double row of vertical scales on the tail. Venomous North American coral snakes often have adjacent red and yellow bands, whereas their nonvenomous counterparts usually have a characteristic black band between the red and yellow bands. For prehospital care in the US, the following strategies are not recommended: incision or excision, use of venom extraction devices, tourniquets, chill methods, and electroshock therapy -- and they can all actually worsen outcomes.  Prehospital providers should focus on rapid transport. Be cognizant of compartment syndrome, but measure compartments when possible, as some envenomations present similarly but have only subcutaneous hypertension. Neurologic effects can be delayed up to 12 hours after coral snake envenomations. Symptoms can include a descending paralysis. For diagnostic testing, consider a CBC, coags, fibrinogen level, electrolytes, cpk, creatine, glucose, and urine studies.  All patients with envenomation should be observed for at least 8 hours. Mark the site of envenomation circumferentially to monitor for changes. Management of patients with snake bites should be treated with supportive care, pain control, and specific antivenom when indicated. FabAV or CroFab is the antivenom of choice for pit viper envenomations. Although FabAV will reduce the duration and severity of symptoms and lab abnormalities, it will not reverse tissue necrosis and may not reverse neurologic effects. Be aware of the possibility for a hypersensitivity reaction or serum sickness to FabAV. Treat with steroids, antihistamine, IV fluids, and epinephrine as appropriate. Coral snake envenomations can be treated with NACSA, which halts or at least limits the progression of muscle paralysis and shortens the clinical course.  Side effects to NACSA include dermal reaction as the most common -- and anaphylaxis as the most severe. Patients with bites from exotic snakes should be monitored, likely in the ICU, for up to 24 hours as toxicity from some venom may have a delayed onset of up to 20 hours. You may have to turn to your local zoo for help with anti-venoms here. Management of pregnant patients is the same as nonpregnant patients with regards to snake envenomations. Dosing of antivenom is based on the amount of venom. Dosing is the same regardless of the age of the patient. All patients requiring antivenom or with suspected envenomation should be admitted.  Seek consultation with your regional poison center and local toxicologist Jeff: So that wraps up the September 2018 episode of Emplify.

"Boomslang" is the first theme of the release, starting with a simple battery with a tom that makes the mishap, so that new percussive elements appear and an arpeggio that leads to the extesis until the break, matching by the melody of a dark pad that Is heard in the background, the break accompanied by a new hypnotic synthesizer explode the return of the battery together with the previous elements until the final break that return the calm and tension until to finish, a track that will be dynamite in the club. "Cratalus" is the second theme, it starts with dark and powerful bass pad that give rise to a second hypnotic synthesizer in conjunction with a shaker that resembles the sound of the rattlesnake, the bass line sound is progressive and deep, dark atmospheres are incorporated , the hypnotic sound of the arpeggio takes the lead role in conjunction with riffs of wild and scratchy synthesizers until the intermediate where a new element more hypnotic and psychedelic pops up that break, that sound predominates until the final intermediate of the theme where it is degrading with an obvious end with the battery each time with less elements, a theme with great character for the dance floor. "Naja" the last track, just like the previous themes begins in a simple way on the drums with a continuous and raspy bass pad at certain times, is incorporating an arpeggio that takes the main role with a melody in the background and riffs of rasped synthesizers that arrive to the break with great presence to later give simple entrance to the bass drum along with the bass pad and progressive bass line where the main arpegio and the other elements of the battery are incorporated again until slowly they are diluted to finalize the theme with the simple kick of the beginning, a track thought for the sublime moment of the after-hours.

In today's VETgirl online veterinary CE podcast, we review the use of antivenom in dogs. Is it worth the $500/bottle? How many bottles should we use? Is it necessary in all cases? So, we interview Dr. Daniel Foy, DACVIM, DACVECC, who published a study called "Retrospective evaluation of the effect of antivenom administration on hospitalization duration and treatment cost for dogs envenomated by Crotalus viridis: 113 dogs (2004-;2012)." This was a retrospective study looking at a large case population (over 100 dogs) who were envenomated with Crotalus viridis, or more commonly known as the prairie rattlesnake (which isn't as bad as other types of Crotalid species). In this study, it appeared that the use of antivenom did not positively affect outcome or duration of hospitalization, and actually increased costs! So, test your envenomation knowledge here in today's VETgirl podcast.
