Randomized Controlled Trial Comparative Study Clinical Trial
General anaesthesia for caesarean section in severe pre-eclampsia. Comparison of the renal and hepatic effects of enflurane and halothane.
In a randomized study of patients undergoing Caesarean section, either enflurane (mean 0.24 MAC-h) or halothane (mean 0.23 MAC-h) and 50% nitrous oxide in oxygen were administered to women (n = 12) with severe pre-eclampsia-eclampsia and to 16 healthy pregnant patients with normal renal and hepatic function. No evidence of nephrotoxicity was found in any pre-eclamptic or normal patient. ⋯ Postoperative liver function tests showed no important changes from preoperative values, although reductive metabolites of halothane were not measured. In patients with severe pre-eclampsia there appears no contraindication to enflurane or, probably, halothane as volatile supplements during general anaesthesia.
