Clinical Trial Summary

Pathophysiology of perioperative fluid management in patients undergoing emergency laparotomy.


Description:

In critically ill patients and patients undergoing major surgery, the combination of internal fluid shifts and fluid retention resulting in extravascular fluid accumulation and postoperative organ dysfunctions, complicates perioperative fluid management and influences patient outcome. Changes in extravascular volume after surgery have been much debated, studies in major surgery suggest that extracellular volume expansion may correlate with intraoperative fluid administration, while other studies show the intravascular volume to be decreased after surgery. Difficulty in obtaining accurate measurements of the fluid phases is recognized and despite years of research, perioperative extravascular volume changes have not been clarified in acute high-risk abdominal (AHA) surgery. It is essential to be able to identify and characterize the transition from necessary fluid resuscitation to harmful fluid volume accumulation, intra- as well as extravascular. The present study seeks to investigate the perioperative fluid status and fluid shifts in patients undergoing AHA surgery, specifically focusing on intra- versus extra-vascular fluid status in patients with intestinal obstruction versus intestinal perforation.

Outcome

Type Measure Description Time frame Safety issue
Primary The fluid distribution, during the early perioperative period (= 5 days), in patients with intestinal perforation versus intestinal obstruction versus postoperative complications with peritonitis. Intra vs. extra vascular. Stroke volume assessment, Bioimpedance measurements perioperative period
Secondary Impact of fluid distribution/fluid overload on preload dependency. Preoperatively, 6 hours postoperatively and on first, third and fifth postoperative day
Secondary Impact of fluid distribution/fluid overload on peripheral perfusion. Preoperatively, 6 hours postoperatively and on first, third and fifth postoperative day
Secondary Correlation between fluid balance just prior to surgery and intraoperative need for vasopressor/inotropes administration. Preoperatively, 6 hours postoperatively and on first, third and fifth postoperative day
Secondary Evaluate the relationship between fluid overload and mortality rate in patients undergoing emergency laparotomy. Preoperatively, 6 hours postoperatively and on first, third and fifth postoperative day
Secondary Association between pre- to postoperative changes in volume status and perioperative fluid volume administration, in patients with intestinal perforation versus intestinal obstruction versus postoperative complications with peritonitis. Preoperatively, 6 hours postoperatively and on first, third and fifth postoperative day
