1982년 6월 1일 부터 12월 31일까지 정상임산부 96례에서 무통분만을 목적으로 특속적 경막외 마취를 실시하여 그 결과를 임상기록이 연령과 산과력에서 가급적 동일한 정상분만 96례의 비교관찰하여 다음과 같은 결과를 얻었다. 1. 임산부의 만족도에 준하여 89.6%에서 우수 또는 양호한 마취효과를 얻었다. 2. 마취효과가 불량한 10(10.4%)례중 2례(2%)는 경막외강의 주입의 실패였다. 이는 숙련도 여하에 따른 난이성의 결과이다. 3. 분만제 2기는 초산부와 경사누에서 공히 연장되었고 초산부는 현격하여 2배이상이 연장된 결과 견인 분만율이 놓았다. 4. 합병증의 대부분은 일과성 합병증으로 경미하였다. 그러나 4례는 혈압의 현격한 하락은 없었으나 원인불명의 태아 곤란증이 합병되어 제왕절개분만을 하였다. 이는 전례가 분만제3기에 고농도(2%)의 국소마취제 주입시기에 발생하였다 이상은 시술에 앞서 견인분만에 대한 대비 그리고 태아곤란증도 대비 할 수 있고 분만생리의 이해와 숙련된 산과요원 그리고 장비가 구비된 여건하에서 임산부의 요청에 의해서만 시도하는 것이 타당하다는 결론이다.

A clinical study was made on 96 cases of patients who were underwent continuous lumbar epiduraㅣanesthesia at the Department of OB & Gy In Cheon Gil Hospital from June 1 to December 31, 1982. These cases (study group) were matched to 96 cases of other normal patients (control group) who were not performed anesthesia, with age, parity and obstetrical history by clinical records. The results were as follows: 1. 86 cases (89.6%) of 96 (study group) was obtained Satisfactory analgesic effect according to subjective feeling of patients, on the others hand, there were 10 unsatisfactory analgesic cases(10.4%). 2. Prolongateion of 2nd stage of labor was noticed in majority of this cases as compared to control group. Prolonged 2nd stage of labor in primigravida was particular as comparing to that of multigravida with more then 2 times. 3. 33 patients (34.9%) had complications of epidural anesthesia. majority of complications was accompained by mild and selflimites. symptions except 4 cases of Fetal destress, which was the most serious compliction and related to high concentration of anesthetics possiblely. 4. 94 cases(98%) of study group were performed Epidural Puncture with success, and 2 cases (2%) were done failed puncture, which indicated difficult ability of this procedure. 5. Satisfactory Analgesic effect was induced when the Extent of block was got on T9-10 Level mostly. 6. In additional Anesthetic injection, primipara group was required more frequent than that of multipara group. 7. In the type of Delivery, 54 pts(54.1%) of study group and 77 pts(81.2%) of control group was carried normal spontaneous vaginal delivery. C-Section was performed in 4 cases (6.3%) of study group because of the fetal distresses. Consequently this anesthetic procedure should be able to do under the careful consideration of indicated patients and preparation of delivery room facility including infants resuscitation and feta monitoring.
