Abstract:
Objective To evaluate the effects of teriipressin on perioperative renal function in patients undergoing liver transplantation. Methods Forty ASA Ⅲ or Ⅳ patients (31 males and 9 females) aged 35-55 yr and weighing 46-81 kg were randomly divided into2 groups (n=20 each): terlipressin group and control group. The patients were premedicated with intramuscular midazolam 2- 3 mg and atropine 0.5 mg. Swan-ganz catheter was placed via the right internal jugular vein and the radial artery was cannulated. Electrocardiography (ECG), blood pressure (BP), heart rate (HR), central venous pressure (CVP) and pulmonary arterypressure (PAP) were monitored during general anesthesia. General anesthesia was induced with midazolam (0.1-0.2 mg/kg), fentanyl (5-10 μg/kg), propofol(1-2 mg/kg) and vecuronium (0.1 mg/kg) and maintained with 0.5%-1.5% isoflurane, propofol infusion at 2-5 mg·kg-1·h-1 and intermittent i.v. boluses of fentanyl and vecuronium. The patients were mechanically ventilated after tracheal intubation. In the terlipressin group, 2 mg of terlipressin was added to 50 ml of normal saline (NS) and was continuously infused at 10 ml/L from beginning of operation until the end of anhepatic phase, while in the control group, NS was infused only. Blood and urine samples were taken before operation(T0), at the end of anhepatic phase (T1), at the end of operation (T2), and on the 1st and 2nd day after operation (T3, T4)for determination of plasma angiotensin Ⅱ (AT- Ⅱ ), serumβ2-microglobulin (MG), blood urea nitrogen (BUN) and creatinine (Cr) concentrations and N-acetyl-βd-glucosaminidase (NAG) concentrations in the urine. Urine output was measured during pre-anhepatic, anhepatic and neo-hepatic phase and on the 1 st and2nd day after operation. Results The urinary NAG and serum β2-MG concentrations were significantly increased at T1 as compared with the baseline at T0in both groups. The urinary NAG, plasma AT-Ⅱ, serum β2-MG, BUN and Cr concentrations were significantly lower and theurinary output was significantly higher during T2-4 in the terlipressin group than in the control group. Conclusion Terlipressin has protective effects on renal function in patients undergoing orthotopic liver transplantation.
