AbstractWe compared the hemodynamic response to laryngoscopy and intubation, as well as emergence and recovery times, when propofol or thiopental were used for rapid intravenous induction of anesthesia in 59 infants undergoing repair of inguinal hernia. An intravenous catheter was inserted under N2O analgesia and atropine 0.01 mg/kg was administered to all patients. Subsequent induction with propofol (3 mg/kg), thiopental (5 mg/kg), or halothane (2%) was followed with succinylcholine (2 mg/kg) and tracheal intubation. Ventilation was manually assisted during surgery, and tracheas were extubated when patients were completely awake. Infants who received propofol showed less hypertensive response to intubation than those who received thiopental or halothane. In the 1- to 6-mo age group, emergence (extubation) time was significantly longer for infants who received thiopental (10.2 +/- 1.4 min) than for those who received propofol or halothane (5.5 +/- 2.5 and 6.2 +/- 1.3 min, respectively). Infants who received thiopental induction had a higher incidence of perioperative airway complications than all others. There was no significant difference in the recovery and discharge times among the three groups. We conclude that when rapid intravenous induction is required for infants, propofol is more effective than thiopental in obtunding the hypertensive response to intubation, and in young infants (1-6 mo) it results in more prompt emergence after short surgical procedures.
