Comparison of halothane, enflurane and isoflurane kidney effects through alanine aminopeptidase/urine creatinine

Abstract:
The kidney effects of halothane, enflurane and isoflurane were evaluated by using the ratio of urinary excretion of alanine aminopeptidase (AAP) to urine creatinine. Thirty patients in ASA class 1 or 2 were studied. None had renal disease nor received nephrotoxic drugs. Groups 1, 2 and 3 received halothane, enflurane and isoflurane respectively. Creatinine and AAP activities in urine spot tests, serum creatinine and BUN levels were determined preoperatively and on the first and second postoperative days. Urine AAP activity and AAP/urine creatinine values increased significantly on the first and second postoperative days compared with the preoperative values in all groups (P < 0.05). The present study did not reveal any significant difference in the kidney effects of halothane, enflurane and isoflurane through AAP/creatinine in spot urine values.
