Abstract

Background: High thoracic epidural anesthesia allows awake coronary artery bypass grafting, avoiding the drawbacks of mechanical ventilation and general anesthesia. Materian and Method: From April, 2005 to September, 2005, 12 patients were underwent awake coronary artery bypass grafting using high thoracic epidural anesthesia. There were 1 female and 11 male patients, with a mean age of $66{\pm}6$ years. Off pump coronary artery. bypass grafting was performed through a median sternotomy using arterial grafts. Result: There were no mortality. Pneumothorax was developed during surgery in 8 patients. Five patients required secondary intubation because of pneumothorax (n=3), bowel herniation (n=1), and hemothorax after chest tube insertion (n=1). Postoperative coronary angiography was performed before discharge in all patients and all the grafts were patent. Conclusion: Our intial experience demonstrated the feasibility of awake off-pump coronary artery bypass grafting. Further study is required to define the indications, advantages and limitations of this strategy.

배경 : 경막외 마취를 이용하여 의식 있는 환자에서 관상동맥우회술을 시행하는 경우 기계 환기 및 전신 마취에 의한 합병증을 피할 수 있는 장점들이 기대된다. 대상 및 방법: 2005년 4월부터 2005년 9월까지 12명의 환자를 대상으로 상흉부 경막외 마취를 이용하여 의식이 있는 상태에서 심폐바이패스를 사용하지 않는 관상동맥우회술을 시행하였다. 1명은 여자였고 11명은 남자였으며 평균 연령은 $66{\pm}6$세였다. 정중 흉골 절개술을 시행한 후 동맥도관만을 이용하여 관상동맥우회술을 시행하였다. 결과: 평균 원위부 문합수는 ${1.8{\pm}0.9\;(1{\sim}3)}$이었으며, 수술사망 예는 없었다. 수술을 시행하는 동안 모두 8 명의 환자에서 기흉이 발생하였으며, 수술 중 기흉 (n =3), 복부내장의 팽창 (n=1), 흉관 삽입 후 발생한 혈흉 (n=1) 등의 원인으로 12 명 중 5 명의 환자에서는 기관 삽관 후 전신마취로 전환이 필요하였다. 모든 환자에서 수술 후 $1.2{\pm}0.6$일째에 관상동맥조명술을 시행하였으며, 모든 우회도관은 개통되어 있었다. 결론: 본원의 초기 경험을 통해 전신 마취를 하지 않고 의식이 있는 상태에서 심폐바이패스를 사용하지 않는 관상동맥우회술을 시행하는 것이 가능함을 확인할 수 있었다 . 이러한 수술 방법의 적응증 및 제한점에 대해서는 향후 경험을 통한 추가적인 연구가 필요할 것으로 생각된다.
