초록

배경: 아스피린과 플라빅스는 관상동맥 환자들에게 가장 흔히 사용하는 항혈소판 제제이나 수술 후 출혈 성향의 증가에 대한 우려 때문에 수술 5일에서 7일 전에 복용을 중단하는 것이 일반적이다. 본 연구에서는 이들 약제들의 지속적 사용이 무심폐기 하 관상동맥우회 술(Off pump coronary artery bypass grafting, Off pump CABG) 후의 결과에 어떤 영향을 미치는지에 관하여 조사하였다. 대상 및 방법: 2004년 3월부터 2005년 2월까지 Off pump CABG를 시행 받은 123명의 환자들을 대상으로 하여 수술 전후에 아스피린과 플라빅스를 끊지 않고 지속적으로 사용한 군(n=45, 36.6$\%$)과 적어도 수술 1일 이전에 끊은 군(n=78, 63.4$\%$) 사이에 수술 전후 혈소판, 헤모글로빈/헤마토크리트 수치, 수술 후 출혈량, 도관 개통률, 수술 시간 등을 비교하였다. 또한 대상환자들을 수술 전에 아스피린을 1달 이상 사용했던 장기 사용군과 그렇지 않은 군으로 구분하여 상기 요소들을 비교하였다. 결과: 수술에 의한 사망은 없었으며 출혈에 관한 합병증으로는 출혈에 의한 재수술과 상부 소화관 출혈이 각각 1예씩 있었다. 지속적으로 사용한 군과 그렇지 않은 군의 비교에 있어서는 수술 직후와 수술 후 1, 2일의 혈소판 수치가 지속적 사용군에서 유의하게 낮았으나(p=0.02, p=0.002, p=0.021) 수술 후 출혈량, 수혈 빈도, 출혈 관련 합병증 및 도관의 개통률에는 차이가 없었다 아스피린을 1달 이상 사용한 장기 사용군의 경우 그렇지 않은 군에 비하여 수술 전후의 혈소판 수치가 지속적으로 낮았으나 출혈량, 수혈 빈도, 합병증 및 도관의 개통률에는 차이가 없었다. 결론: 아스피린과 플라빅스의 Off pump CABG 전후의 지속적 사용은 수술 후 일시적인 혈소판 수치의 감소를 초래할 수 있으나 수술 후 출혈량, 수혈 여부, 수술 시간, 출혈과 관련된 합병증 및 도관의 개통률에는 영향을 주지 않았다. 그러므로 Off pump CABG에 있어서 아스피린과 플라빅스는 수술 전까지 지속적으로 사용하여도 될 것으로 생각한다.

Background: The benefits of preoperative use of aspirin and plavix in coronary patients have been well documented. Due to their bleeding tendency, there have been many discussions about when to stop the antiplatelet agent before operation. We evaluated the effects of preoperative continuous use of aspirin and plavix in OPCAB patients. Material and Method: 123 patients underwent OPCAB from March, 2004 to Feb., 2005. We divided them into two groups; those who had continuous administration of aspirin and plavix during the preoperative period (n=45, 36.6$\%$) and those who discontinued them at least one day before the operation (n=78, 63.4$\%$). We then compared the platelet count, hemoglobin/hematocrit level, graft patency, postoperative bleeding and related complications, and operation time between the two groups. The patients were also divided into long-term users ($\geq$ 1 month) and short-term users (< 1 month), with the aforementioned factors equally compared. Result: There was no statistical difference between the two groups regarding postoperative bleeding, related complications, graft patency, operation time and mortality. Continuous users showed significantly low platelet levels on immediate post operation (p=0.02), postoperative day (POD) $\sharp$1 (p=0.002) and POD $\sharp$2 (p=0.021), respectively. But there was no difference on POD $\sharp$7. Long-term users showed statistically significant difference in pre- and postoperative platelet count, but none in postoperative bleeding and related complications. Conclusion: Continuous use of aspirin and plavix did not increase postoperative bleeding or related complications. Also graft patency and mortality had no statistical differences in continuous users. We think that there is no need to stop aspirin and plavix before OPCAB.
