Abstract:
Objective To determine the risk factors for development of early acute renal failure (ARF) after orthotopic liver transplantation (OLT) in patients with normal renal function.Methods Sixty ASA Ⅱ or Ⅲ patients aged 28-64 yr weighing 35-88 kg undergoing OLT were studied.Their preoperative serum Cr and BUN were within normal range.Early ARF was defined as serum Cr≥132 μmol/L and/or BUN≥18 mmol/L within 24 h after operation.The patients were divided into 2 groups: ARF group and non-ARF group.Arterial blood samples and urine specimens were collected before induction of anesthesia for determination of blood β2-micreglobulin(β2-MG) and urinary β2-MG and N-acetyl-β-D-glucurenidnse (NAG). Factors including preoperative liver function,preoperative blood and urinary β2-MG,the amount of urine output and bank blood infused during operation,MAP during anhepatic and neohepatic phase,the amount of vnsoactive drugs and diuretics used during operation,hypotension and arrbythmia during operation were recorded.The risk factors were identified by logistic regression analysis.Results Logistic analysis indicated that serum β2-MG higher than normal value before operation and persistent hypotensien during operation were closely correlated with development of early ARF after OLT.Conclusion Serum β2-MG higher than the normal value before operation.and persistent hypotension during operation are the risk factors for early ARF after OLT.
