This study compares anesthetic maintenance, hemodynamic stability, and speed of recovery obtained with inhalational halothane versus intravenous alfentanil anesthesia administered continuously. In two groups of patients, anesthesia was induced with sodium thiopental, maintained with 70% nitrous oxide in 30% oxygen, and either halothane (n = 10) or a continuous infusion of alfentanil (n = 10). The administration of the allocated anesthetic was adjusted according to strict predefined criteria of inadequate anesthesia. After endotracheal intubation, hemodynamics (heart rate, systolic and diastolic pressure) changed less in the alfentanil group (P less than .01). Overall hemodynamic stability was the same in both groups. In neither group was there recall of intraoperative events. Recovery was assessed by the time from cessation of nitrous oxide administration to return of spontaneous ventilation, response to simple command, extubation, orientation, and discharge from the recovery area. The time taken to respond to simple command was significantly shorter in the alfentanil group (P less than .05), but other indices of recovery were similar.

D005283 Fentanyl A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance.

D006221 Halothane A nonflammable, halogenated, hydrocarbon anesthetic that provides relatively rapid induction with little or no excitement. Analgesia may not be adequate. NITROUS OXIDE is often given concomitantly. Because halothane may not produce sufficient muscle relaxation, supplemental neuromuscular blocking agents may be required.
