Four pediatric patients, who were 2, 3, 6 and 8 years old in 1993, had received repeated general anesthesia 8, 19, 31 and 25 times respectively for laryngeal microsurgery since their infancies. The mean intervals between anesthesia were 45, 103,
37
and
91 days and the mean durations of anesthetia were 79, 86, 73 and 78 minuites respectively. Enflurane was used most frequently without and remarkable complication except one episode of pneumonia. The hepatic enzymes increased transiently in two
