Clinical Analysis of Balanced Anesthesia (Diazepam, Meperidine, Nitrous Oxide - Oxygen, Muscle relaxant combination) of 10,456 Cases in Ewha Womans Uninversity Hospital

Bananced anesthesia was termed because each intravenous compound employed was selected and administrated for a specific action, e.g.m analgesia, sedation, amnesia and muscle relaxation. This technique is a safe, simple technique that has no demonstrable toxic effects on liver or kidneys. The cardiovascular system remains stable during anesthesia. The method has proved useful in aged and poor risk patients. In using this technique, fentanyl and droperidols are used commonly. Unfortunately, we could not get the commercially available fentanyl and droperidol in Korea. So the present author have used meperidine or morphine as substitute for fentanyl, diazepam as substitute for droperidol since 1977. The author analyzed the anesthetic records of 10,456 cases in relation with the years, sex, age, operation site, dosages per body weight and operation time during the period of 1977 to 1983. The result are as follows: 1) Of the total 14,078 cases, 74.3%(10,456 cases) was the balanced anesthesia and showed increasing tendency annually. 2) The ratio of males to female was 1:1.9. 3) The most common age group was 3rd decades. 4) The most common operation was Cesarean section. 5) The mean dosages for meperidine was 0.89mg/kg/hr and diazepam was 0.17mg/kg/h.
