- Sevoflurane (Type: PLACEBO_COMPARATOR): Anesthesia was maintained with sevoflurane,and the incidence and severity of emergence agitation was investigated.
- Remifentanil (Type: ACTIVE_COMPARATOR): Anesthesia was maintained with sevoflurane and remifentanil. The incidence and severity of emergence agitation was compared with sevoflurane group.
- Alfentanil (Type: ACTIVE_COMPARATOR): Anesthesia was maintained with sevoflurane and remifentanil, and alfentanil was administered 10 min before the end of surgery.~The incidence and severity of emergence agitation was compared with sevoflurane group.
- Thiopental (Type: OTHER): General anesthesia was induced with thiopental 5 mg/kg, rocuronium 0.6 mg/kg and sevoflurane in all patients.
- Rocuronium (Type: OTHER): General anesthesia was induced with thiopental 5 mg/kg, rocuronium 0.6 mg/kg and sevoflurane in all patients.
