Recovery after halothane anaesthesia induced with thiopental, propofol-alfentanil or halothane for day-case adenoidectomy in small children.
We studied recovery from halothane anaesthesia in 93 children, aged 1-3 yr, undergoing day-case adenoidectomy. Children were allocated randomly to receive thiopental 5 mg kg-1 (group TH), alfentanil 10 micrograms kg-1 and propofol 3 mg kg-1 (group PAH) or 5% halothane (group HH) for induction of anaesthesia. In group TH, tracheal intubation was facilitated with succinylcholine (suxamethonium) 1.5 mg kg-1. In groups PAH and HH, tracheal intubation was performed without neuromuscular block, and succinylcholine was used only if required. Anaesthesia was maintained with 1-3% halothane during spontaneous respiration. Times to achieving predetermined recovery end-points were recorded. Quality of recovery was assessed using a score of 1-9 (best to worst) for sedation, crying, restlessness and agitation. A postoperative questionnaire was used to determine the well-being of the child at home, 24 h after operation. Emergence from anaesthesia (response to non-painful stimuli) occurred earlier in group HH (mean 9 (SD 6) min) than in groups PAH (13 (6) min, P < 0.01) and TH (18 (14) min, P < 0.01). Sitting up, walking and home readiness were achieved earlier in groups PAH and HH than in group TH (P < 0.05 for each variable). Children in group TH were more sedated during the first 30 min after anaesthesia than those in the two other groups (P < 0.05) while emergence-related delirium was more common in group HH than in group TH (P < 0.01). Well-being at home was similar in all groups. We conclude that induction of halothane anaesthesia with propofol-alfentanil or halothane provided more rapid recovery and earlier discharge than that with thiopental.
