Observational StudySex difference in formation of propofol metabolites: a replication study.
Women recover faster from propofol anaesthesia and have been described to have a higher incidence of awareness during surgery, compared to men - an effect that may be inherent in sex differences in propofol metabolism. In an observational study, 98 ASA I-II patients treated with continuous propofol infusion were recruited. ⋯ There was, however, no significant impact of gene polymorphisms on propofol biotransformation. The results, which are supported by a previous pilot study using a propofol bolus dose, suggest that, compared to men, more rapid propofol metabolism may occur in women - a factor that may contribute to the mentioned differences in the efficacy of propofol anaesthesia between male and female patients.
