Pre-operative fluid resuscitation in the emergency general surgery septic patient: does it really matter?

Abstract

Abstract Objective Emergency general surgery (EGS) patients presenting with sepsis remain a challenge. The Surviving Sepsis Campaign recommends a 30 mL/kg fluid bolus in these patients, but recent studies suggest an association between large volume crystalloid resuscitation and increased mortality. The optimal amount of pre-operative fluid resuscitation prior to source control in patients with intra-abdominal sepsis is unknown. This study aims to determine if increasing volume of resuscitation prior to surgical source control is associated with worsening outcomes. Methods We conducted an 8-year retrospective chart review of EGS patients undergoing surgery for abdominal sepsis within 24 h of admission. Patients in hemorrhagic shock and those with outside hospital index surgeries were excluded. We grouped patients by increasing pre-operative resuscitation volume in 10 ml/kg intervals up to > 70 ml/kg and later grouped them into 30 ml/kg (p = 0.02). These groups had median qSOFA scores (1.0 vs. 1.0, p = 0.06). There were no differences in time to operation (6.1 vs 4.9 h p = 0.11), ventilator days (1 vs 3, p = 0.08), or hospital LOS (8 vs 9 days, p = 0.57). Relative risk regression correcting for age and physiologic factors showed no significant differences in mortality between the fluid groups. Conclusions Greater pre-operative resuscitation volumes were initially associated with significantly higher mortality, despite similar organ failure scores. However, fluid volumes were not associated with mortality following adjustment for other physiologic factors in a regression model. The amount of pre-operative volume resuscitation was not associated with differences in time to operation, ventilator days, ICU or hospital LOS.
