Aprotinin을 투여한 개심술 환자에서 Kaolin과 Celite Activator를 이용한 Activated Coagulation Time(ACT) 측정의 비교
김정택,선경,이춘수,백완기,조상록,김현태,김혜숙,박현희,김광호,Kim, Joung-Taek,Sun, Kyung,Lee, Choon-Soo,Baik, Wan-Ki,Cho, Sang-Rock,Kim, Hyun-Tae,Kim, Hea-Sook,Park, Hyun-Hee,Kim, Kwang-Ho 대한흉부심장혈관외과학회 1998 Journal of Chest Surgery (J Chest Surg) Vol.31 No.9
개심수술에서 Aprotinin에 의한 ACT가 연장되는가를 알아보기 위해 서로 다른 표면 촉매제인 kaolin (K-ACT)과 celite(C-ACT)를 이용하여 동시에 측정 비교하였다. 개심수술을 받은 22명의 성인을 대상으로 하여 Hemocron 8000 system을 이용하여 동시에 ACT를 측정 하였는데 aprotinin과 heparin 투여 전(Phase I), Aprotinin투여 후 heparin 투여 전(Phase II), heparin투여 5분 후(Phase III), haparin투여 30분 후(Phase IV), heparin투여 60분 후(Phase V), heparin투여 90분 후(Phase VI), protamin투여 30분 후(Phase VII)에 각각 측정하였다. Phase I, II, III에 두 군간에 차이가 없었으나 heparin투여 30분 후에는 C-ACT가 928$\pm$400초 K-ACT가 572$\pm$159초였고 60분 후에는 C-ACT가 888$\pm$254초 K-ACT가 535$\pm$186초 90분 후에는 C-ACT가 686$\pm$141초 K-ACT가 484$\pm$54초로 K-ACT에 비해 C-ACT가 통계학적으로 의의있게 증가하였다. 그러나 protamin투여 후에는 C-ACT가 137$\pm$26초 K-ACT가 139$\pm$28초로 두군간에 차이가 없었다. 이상의 결과에서 aprotinin투여 후 ACT는 연장이 되는 것이 아니라 activator로 celite를 사용했기 때문인 것으로 생각된다. 결론적으로 aprotinin을 투여한 개심수술에서 정확한 ACT수준을 측정하기 위하여 celite activator보다 kaolin activator를 사용해야 하며 heparin은 보통용량을 투입하여야 할 것으로 생각된다. Background: High-dose aprotinin has been reported to enhance the anticoagulant effects of heparin during cardiopulmonary bypass ; hence, som authors have advocated reducing the dose of heparin in patients treated with aprotinin. Material and Method: The ACT was measured before, during and after cardiopulmonary bypass, with Hemochron 801 system using two activators of celite(C-ACT) and kaolin(K- ACT) as surface activator. From June, 1996 to February, 1997, 22 adult patients who were scheduled for elective operation were enrolled in this study. Result: The ACT without heparin did not differ between C-ACT and K-ACT. At 30 minutes after anticoagulation with heparin and cardiopulmonary bypass, the average C-ACT was 928${\pm}$400 s; K-ACT was 572${\pm}$159s(p<0.05). After administration of protamine, C-ACT was 137${\pm}$26 s; K-ACT was 139${\pm}$28s, which were not statistically significant. Conclusion: Our results showed that the significant increase in the ACT during heparin- induced anticoagulation in the presence of aprotinin was due to the use of celite as surface activator, rather than due to enhanced anticoagulation of heparin by aprotinin. We conclude that the ACT measured with kaolin provides better monitoring of cardiac surgical patients treated with high dose aprotinin than does the ACT measured with celite. The patients treated with aprotinin should receive the usual doses of heparin.

Subclavian artery(SCA) injuries are rare, accounting for only 1 to 2% of all acute vascular injuries. The majority of SCA injuries are occured by motor vehicle accident and by penetrating trauma, only 1 to 5% of all subclavian artery injuries occurred by blunt mechanisms. The incidence of brachial plexus injury is also rare and 60% of brachial plexus injuries induced by blunt injury is occurred by motor vehicle accident. Aggressive diagnostic work-up is recommended for the patients with high suspicious index and repair is essential for the successful management of these rare vascular injuries, We report the experience of one case of combined subclavian artery and brachial plexus injuries due to blunt trauma.
