Alfentanil and propofol infusions for surgery in the burned patient.
We have studied combinations of alfentanil and propofol for total i.v. anaesthesia in 24 severely burned patients. No inhalation agents were used. After a loading dose of alfentanil 100 micrograms kg-1, the intraoperative requirement was 1.24 (SEM 0.7) micrograms kg-1 min-1, and after a propofol induction dose of 2 mg kg-1 the maintenance rate was 100 micrograms kg-1 min-1. Initial hypotension occurred after induction of anaesthesia, but during the operation, cardiovascular variables were stable. After adequate antagonism of neuromuscular block, respiratory depression persisted in three patients when the two agents were discontinued simultaneously; this was not seen when alfentanil was discontinued 15 min before propofol. Quality of recovery was good, and satisfactory postoperative analgesia was present in the majority of patients 2 h after operation. This study indicates that total i.v. anaesthesia with a combination of alfentanil and propofol appears to be satisfactory in burned patients.
