Remote Ischemic Preconditioning in Patients Undergoing Acute Minor Abdominal Surgery — PUMAS  

Endothelial Dysfunction Clinical Trial

Official title:
Remote Ischemic Preconditioning in Patients Undergoing Acute Minor Abdominal Surgery: The PUMAS Study

Clinical Trial Summary

This study examines if remote ischemic preconditioning in patients undergoing minor acute abdominal surgery (laparoscopic cholecystitis due to acute cholecystitis) is associated with a modulation of endothelial dysfunction. half of the patients will receive remote ischemic preconditioning prior to surgery, the other half will serve as controls.

Clinical Trial Description

Remote ischemic preconditioning (RIPC) consists of cycles of forearm or leg ischemia and reperfusion by the inflation of a blood-pressure cuff over the systemic blood pressure for brief periods. The procedure is simple, safe and with no clear side effects. In clinical studies covering acute cardiology RIPC has effectively reduced myocardial injury, postoperative cardiovascular complications and cardiac mortality. Recently, the effect of RIPC on attenuating ischemia-reperfusion injury has been investigated in non-cardiac surgery as well. The organ specific ischemia-reperfusion injury, systemic oxidative stress and inflammatory response were attenuated due to the intervention but a complete understanding of the underlying protective mechanisms of RIPC is however still lacking. Experimental and clinical studies have implicated that the stimulus of RIPC is transmitted from the preconditioned tissue to other tissues and organs by humoral, neural and systemic anti-inflammatory mediators. The humoral and neural pathway are thought to be dependent on endogen substances such as adenosine, bradykinin, nitrogen oxide (NO) and calcitonin-gene-related-peptide (CGRP). ;
