Contributor: Aaron Lessen, MD Educational Pearls: Historically, pancreatitis has been treated with aggressive IV fluid rehydration. Recently published data shows this may not be appropriate. A randomized, controlled, multi-hospital trial evaluated outcomes for patients with acute pancreatitis receiving lactated Ringer's solution Aggressive fluid resuscitation group received 20ml/kg bolus + 3ml/hour Moderate fluid resuscitation groups received either 10 ml/kg bolus if hypovolemic or no bolus if normovolemic. Both moderate resuscitation groups received 1.5ml/hr. The primary outcome was development of moderately severe or severe pancreatitis. 22.1% of aggressive fluid resuscitation and 17.3% of moderate fluid resuscitation patients developed primary outcome. The safety outcome was fluid overload. Fluid overload developed in 20.5% of aggressive resuscitation group and only 6.3% of moderate resuscitation group. This trial was ended early due to differences in safety outcomes without obvious difference in primary outcome Overall, aggressive fluid resuscitation had no benefit in treatment of acute pancreatitis and providers should be aware of fluid overload risk.

When should we give fluids in sepsis? How much? This is a question that has troubled emergency physicians, intensivists and anaesthetists for decades. Given how common the condition is, it is surprising that there is such a paucity of quality evidence to guide practice. Dr Stephen McDonald is an emergency physician from Perth, Australia, and is heading up the ARISE-Fluids trial that will explore the question of whether earlier vasoconstrictor support and restriction of fluids in the early resuscitation period improves outcomes. This interview was recorded at the 20th annual meeting of the ANZICS Clinical Trials Group in Noosa, Queensland

Vasopressor Agents or Fluid Resuscitation for the Treatment of Uncontrolled Hemorrhagic Shock, an Experimental Approach in a Porcine Liver Trauma Model The standard approach to the traumatized victim in uncontrolled hemorrhagic shock is to infuse large amounts of crystalloid and colloid fluids as early, and as rapidly as possible. The aim of this strategy is to restore intravascular volume immediately and to maintain vital organ perfusion. The results of many laboratory studies and one clinical trial question the effectiveness of this treatment recommendation and suggest that in the case of uncontrolled hemorrhage aggressive fluid resuscitation may even be harmful. Hence, we evaluated the effects of fluid resuscitation vs. epinephrine vs. vasopressin vs. saline placebo on hemodynamic variables, regional organ blood flow, and short term survival in an animal model of uncontrolled hemorrhagic shock. Twenty-eight anesthetized pigs were subjected to a severe liver injury, which resulted in an average blood loss of 35 mL/kg within 30 minutes. When mean arterial pressure was < 20 mmHg, and heart rate declined progressively, the pigs were randomly assigned to receive either 1000 mL lactated Ringer´s solution and 1000 mL of gelatine solution (n=7), or an intravenous bolus dose and continuous infusion of 45 µg/kg epinephrine (n=7), or 0.4 IU/kg Vasopressin (n=7), or saline placebo (n=7). At 30 minutes after therapeutic intervention all surviving animals have been fluid resuscitated and further blood loss has been controlled surgically. Mean ± SEM arterial blood pressure at 5 minutes after therapeutic intervention was significantly (p< 0.0001 for vasopressin vs. epinephrine vs. placebo and p< 0.04 for vasopressin vs. fluid resuscitation) higher after vasopressin vs. fluid resuscitation vs. epinephrine vs. saline placebo (58 ± 9 vs. 32 ± 6 vs. 19 ± 5 vs. 7 ± 3 mmHg; respectively). Although vasopressin improved regional organ blood flow, this effect did not result in further blood loss stemming from the liver injury (vasopressin vs. fluid resuscitation vs. epinephrine vs. saline placebo 10 minutes after intervention, 1343 ± 60 vs. 2536 ± 93 vs. 1383 ± 117 vs. 1326 ± 46 mL; respectively; p
In severe hemorrhagic shock, left ventricular (LV) diastolic dysfunction is an early sign of cardiac failure due to compromised myocardial oxygenation. Immediate fluid replacement or, in particular, administration of a hemoglobin-based oxygen carrier (diaspirin cross-linked hemoglobin; DCLHb) improves myocardial oxygenation; therefore, positive effects on LV diastolic function could be expected. The effects of fluid resuscitation from severe hemorrhagic shock with DCLHb were investigated in 20 anesthetized domestic pigs. After generation of a critical left anterior descending coronary artery stenosis (narrowing of the artery until disappearance of reactive hyperemia after a 10-second complete vessel occlusion), hemorrhagic shock (mean arterial blood pressure 45 mm Hg) was induced within 15 min by controlled blood withdrawal and maintained for 60 min. Fluid resuscitation consisted of replacement of the plasma volume withdrawn during hemorrhage by infusion of either 10% DCLHb (DCLHb group, n = 10) or 8% human serum albumin (HSA) oncotically matched to DCLHb (HSA group, n = 10). After completion of resuscitation, an observation period of 60 min elapsed. Measurements of central hemodynamics, myocardial oxygenation, and LV Stolic function were performed at baseline, after induction of critical coronary artery stenosis, after 60 min hemorrhagic shock, immediately after resuscitation, and 60 min later. While 5 out of 10 animals treated with died within the first 20 min after fluid resuscitation from acute LV pump failure, all DCLHb-treated animals survived until the end of the protocol (p < 0.05). Despite superior myocardial oxygenation due to augmentation of the arterial O-2 content as well as of coronary perfusion pressure, no beneficial effects on LV diastolic function were observed after infusion of DCLHb. Peak velocity Of LV pressure decrease (dp/dt(min)) did not reveal significant differences between the two groups. Immediately after completion of fluid resuscitation with DCLHb, the time constant of LV diastolic relaxation (tau) was prolonged when compared with HSA-treated animals (p < 0.05), indicating retardation of early LV diastolic relaxation. Our data suggest that DCLHb fails to improve LV diastolic function after fluid resuscitation from severe hemorrhagic shock. However, positive effects on myocardial perfusion. and oxygenation result in a significant reduction of the mortality of severe hemorrhagic shock. Copyright (C) 2001 S.Karger AG, Basel.
