Clinical Trial Summary

The purpose of this study is evaluate the medication vasopressin for its ability to preserve kidney function in patients undergoing liver transplantation.


Description:

Renal failure is a common complication of liver disease. Hepatorenal syndrome is caused by a dysfunctional global circulation in the setting of liver disease: Increased flow to the mesenteric circulation is a contributor to decreased blood flow to the kidneys (1). Renal failure often worsens in the perioperative period of liver transplantation since the kidneys are further stressed by reduced flow due to inferior venacava occlusion, decreased blood flow to the kidneys from anesthetics, as well as hypotension from volume shifts, such as when large volumes of ascites are removed. Renal failure is a cause of major morbidity and mortality in patients undergoing liver transplantation.

Vasopressin is a logical choice of therapy in this context as the effects of the drug work to particularly increase renal blood flow and glomerular filtration rate due to the location of specific vasopressin receptors within the renal vasculature. It has been suggested that the use of splanchnic (and systemic) vasoconstrictors such as terlipressin (a vasopressin analog) or alpha-1-adrenoceptor agonists (midodrine or noradrenaline) may improve renal function in patients with type 1 Hepatorenal Syndrome.

Six studies (with only one randomized study in a small series of patients) have shown that terlipressin improves renal function in these patients (2-7). This drug is available in Europe, but not in the United States. However, while anesthesiologists commonly use vasopressin during liver transplantation in the setting of hepatorenal syndrome or vasodilatory shock, the validity of this practice for its effects on renal function and outcomes has not been rigorously studied (8-10). Therefore, the purpose of this study is to evaluate the effects of low-dose vasopressin on intraoperative and perioperative renal function in liver transplant patients.

This study will be a randomized, double-blind controlled trial performed in adult liver transplant patients coming to surgery for chronic liver disease; the major end-points of analyses are renal function tests in the perioperative period.

Intervention

Drug:
Vasopressin
Patients randomly assigned to the experimental arm of the study will receive vasopressin 0.5U/hr IV (20 U vasopressin in 250mL of 0.9% NaCL to infuse at a rate of 6.25mL/hr) via internal jugular catheter. Vasopressin infusion is started at the time of incision and is stopped at the time abdominal closure is completed
Normal saline placebo
Patients randomly assigned to the placebo arm of the study will receive placebo (0.9% NaCl to infuse at a rate of 6.25 mL/hr) via internal jugular catheter
