초록
배경; 심막유착은 심장을 재수술하는 경우 큰 문제가 된다. 이 연구의 목적은 실험적 심막유착에서 sodium carboxymethyl cellulose의 효과를 관찰한 것이다. 대상 및 방법; 24마리의 토끼들을 12마리씩 2군으로 나누어 심막에 찰과상을 가하여 심막중피에 손상을 주었다. A군은 링거액을 주었고 B군은 3% sodium carboxymethyl cellulose액을 주었다. 수술 3주후에 A군과 B군의 유착정도를 비교하였다. 결과; 심막유착의 정도를 점도와 형태로 평가하였다. 점도에 따른 점수는 3이상일 경우 임상적으로 유착이 있다고 판단하였다. 대조군인 A군에서는 100%유착을 보였으나 연구군인 B군에서는 25% 의 심막유착을 나타냈다. (p<0.0001). 형태에 따른 점수도 두군사이에 유의성을 나타냈다. 결론; 3% sodium carboxymethyl celluosedor을 심막내로 주임하는 것은 동물실험에서 심막유착의 빈도를 감소시켰다.
Background; Pericardial adhesion poses a major problem during re-operative cardiac surgery. The purpose of this study was to determine the effect of sodium carboxymethol cellulose on experimental pericardial adhesions. Material and Method; Twenty-four rabbits were divided into 2 groups of 12 rabbits each and pericardial mesothelial injury was induced by abrasion. Group A included rabbits receiving intrapericardial injection of Ringer's solution, and Group B included rabbits receiving intrapericardial injection of 3% sodium carboxymethoyl cellulose solution. Three weeks after the surgery, the incidence of adhesions in Group A was compared with that in Group B. Result; Pericardial adhesions were evaluated by tenacity and type scores. Tenacity scores of 3 or greater were considered clinically significant adhesion. Pericardial adhesion was found in 100% of rabbits in group A. However 25% of the rabbits in Group B had pericardial adhesions(p<0.0001). Type scores were also considered clinically significant between 2 groups. Conclusion; Our findings demonstrated that intrapericardial injection of 3% sodium carboxymethyl cellulose solution reduced the incidence of pericardial adhesions in an animal models.
