Althesin and pancuronium in chronic liver disease

Abstract

Summary: In 32 patients with chronic liver disease, undergoing major abdominal surgery, anaesthesia was induced with either Althesin (alphaxalone and alphadolone acetate) or thiopentone, and maintained with nitrous oxide, oxygen and increments of either pethidine or fentanyl. The patients were ventilated artificially to maintain PaCOj values in the normal range. Pancuronium bromide was used as the muscle relaxant. Liver function tests at 24 hr and 5 day after surgery showed only minor changes compared with findings before operation. There was no significant difference between the Althesin and thiopentone groups. In two patients with severe obstructive jaundice there was difficulty in reversing the effects of pancuronium, but "pancuronium resistance" was observed in all patients. It is concluded that the anaesthetic sequence described, with either Althesin or thiopentone induction, is satisfactory with respect to changes in liver function in patients with chronic liver disease undergoing major surgery. © 1975 Macmillan Journals Ltd.
