Perioperative perfusion strategies for optimal fluid management in liver transplant recipients with renal insufficiency

Renal Insufficiency (RI) is a common finding in patients suffering from end-stage liver disease. The causes of RI are reported to be multifactorial and the degree of RI can range from early functional impairment to hepatorenal syndrome (HRS). The process of liver transplantation is highly likely to exacerbate the symptoms and sequelae of renal dysfunction. RI continues to be a cause of morbidity and mortality in the intraoperative and postoperative periods. With careful evaluation and monitoring in addition to appropriate intervention, a uniformly good outcome may be possible even for these most complicated patients. This paper will describe successful perfusion interventions carried out during the three phases of liver transplantation: pre-anhepatic, anhepatic and reperfusion at our institution for a three-year period. Intraoperative plasmapheresis (n = 3)., continuous veno-venous hemofiltration (CVVH) (n = 7), intraoperative dialysis (n = 8), and intraoperative dialysis with fluid removal (n = 3) techniques will be presented for review.
