Abstract

Orthopedic surgery was performed under Thalamonal-N2O-O2 anesthesia by an intravenous injection of a small dose of Thalamonal and N2O inhalation. Respiratory rate was compared before and after intravenous administration of nalorphine at the end of operation. From 22 cases, the following results were obtained: 1) Average dose of Thalamonal during induction of anesthesia was 1.67ml/10kg. During induction, rigidity of chest wall developed in 5 cases, 2) Intermittent injections of Thalamonal for maintenance of anesthesia were needed at. each 43. 8 min. interval, and average dose of Thalamonal was 0. 013 ml/kg/30min. 3) After injection of nalorphine, average rate of respiration per minute increased from 15. 1 to 21. 1(39. 9%) 4) 21 cases among 22 cases recovered promptly after discontinuation of N2O, and recovery was delayed in 1 case. Self extubation was seen in 3 cases.
