简要总结

The goal of this clinical trial is to test the efficacy of intravenous ascorbic acid in preventing the postreperfusion syndrome in liver transplantation. The main questions it aims to answer are:

  • Can intravenous ascorbic acid prevent postreperfusion syndrome in liver transplantation ?
  • Can ascorbic acid decrease the incidence of liver graft dysfunction after liver transplantation?
  • Can ascorbic acid decreased the incidence of postoperative complications after liver transplantation ?

Participants will receive 1.5 g of intravenous ascorbic acid diluted in 100 ml of saline or 100 ml of saline alone, during the anhepatic phase of liver transplantation before reperfusion of the new graft.

Researchers will compared the incidence of postreperfusion syndrome in both groups.

详细描述

Researches will compared:

  • Incidence of postreperfusion syndrome in liver transplantation
  • Changes in interleukin values and other inflammatory markers before and after transplantation
  • Incidence of liver graft dysfunction between groups
  • Incidence of acute renal failure and other complications between groups
