Abstract

Continuous epidural pain block with a local anesthetic agents is a commonly employed technique for pain relief after thoracotomy. In this study, we evaluated the effectiveness of the continuous epidural pain block in 19 patients undergoing elective lateral or posterolatrral thoracotomy with control group(n=19) from November 1994 to July 1995, Epidural lidocaine and morphine mixtures were injected via an epidural catheter as a bolus after operation, and then bupivacaine and morphine mixtures were injected continuously following 5 or 6 days. The pain score, upper arm elevation(ROM score), and respiratory rate were significantly changed(P<0.05) from 30min after injection. The CO2 tension of arterial blood was decreased significantly(P<0.05) from 2hr after injection. The postoperative hospital days were decreased significantly(P<0.05). Side effects of the epidural pain block were urinary retention(n= 10), urticaria(n=2) and a case of headache. There was no postoperative lung atelectasis. We conclude that the continuous epidural pain block is good for prevention of the postoperative lung complication and early recovery after thoracotomy.

마약성 진통제와 국소마취제에 의한 지속적 경막외마취는 개흉술후 통증감소를 위한 방법으로 널리 사용되고 있다. 본 연구에서는 지난 1994년 1월부터 1995년 7월까지 본원 흉부외과에서 츠방 혹은 후측방 개흉술을 받은 환자 38명을 대상으로 19명씩 실험군과 대조군으로 구분하여 실험군에 경막외마취를 시행하여 그 효과를 조사하였다. 먼저 lidocaine과 norphine을 섞어 경막서 지속적 외도관을 통해 주사하고 그후 bupivacaine과 morphine을 섞어 술후 5∼6일간 지속투여를 하였다. 대조군에 비해 실험군에서 환자의 통증수치와 상지거상능력과 호흡수는 주사추 30분부터 통계적으로 의미 있게 변화되어 술후 통증이 경감되고 있음을 알 수 있었고, 말초동맥혈 이산화탄소분압은 2시간 후부터 통계적으로 의미 있게 줄어들어 환자가 효과적인 호흡을 하고 있음을 알 수 있었다. 술후 재원기간도 의미 있게 줄어들었다. 경막외마취의 주요한 합병증으로는 뇨정체가 있었으나 심각하지는 않았다. 이상의 결과로 우리는 개흉술후 경막외마취가 우수한 통증완화 효과가 있어 술후 폐합병증을 예방하고 술후 빠른 회복에도 좋은 영향을 미치는 것으로 생각한다.
