In 97 cases of uncomplicated Cesarean section proceeding under 0.5% fluothane anesthesia with N₂O and O₂, 2.5% Pentothal sedium(clinical induction doses) was enough until umbilical cord clamp without any supplemental doses but muscle relaxation from succinylcholine might not be potentiated with 0.5% fluothane. On the other hand, Apgar score and postpartum uterine contractility was depending upon duration of anesthesia but it was not so serious problem. Also, anesthesia induction and recovery was rapid, and post operative pulmonary and other complication, even vomiting, did not occur. Conclusively, it is interesting that low concentration of fluothane with nitrous oxide are probably ideal anesthesia method for Cesarean section.
