Abstract

Background: Although complications from transfusion are known to happen, transfusion is performed during most open heart surgeries. The aim of this study was to investigate the possibility of performing cardiac surgery without allogenic blood transfusion. Material and Method: Between January to August 2007, 44 consecutive patients who underwent open heart surgery with using various blood conservation methods were retrospectively enrolled. They were divided into group I (the onpump group, n=17) and group II (the offpump group, n=27). The blood conservation methods were intraoperative autologous donation, cell saver, retrograde autologous priming, conventional ultrafiltration and modified ultrafiltration. Antianemic agents were administered to all the patients postoperatively. We analyzed the possibility of bloodless operations, the causes of homologous transfusion, the serial change of the hematocrit and the postoperative chest tube drainage, and we compared the results between the two groups. If comparison between the two groups was not reasonable, then we compared two groups with the individual control groups I and II (49 patients) in 2006. Result: 40 (90.9%) of 44 patients were successfully operated on without transfusion and the success rate was 88.2% (15/17) for group I and 92.6% (25/27) for group II. There was no statistical difference between the two groups (p=NS). The causes of transfusion were 2 cases of postoperative bleedings, 1 case of intraoperative bleeding and 1 mistake of the indication for transfusion. There was no statistical difference of the total chest tube drainage (Group I: $417{\pm}359mL$, Group II: $451{\pm}237mL$) (p=NS), but the total chest tube drainages of the two groups were less than each of the control groups 1 and II (p<0.05). The lowest hematocrit level of Group I was $16.4{\pm}2%$, and this occurred just after infusion of cardioplegics and the hematocrits of both groups were recovered to the preoperative level at 2 months postoperatively. Conclusion: In this study, bloodless open heart surgery could be performed in 90.9% of the patients with intraoperative autologous donation, cell saver, retrograde autologous priming, conventional ultrafiltration and modified ultrafiltration. A combination of various blood conservation methods is the most important and bloodless cardiac surgery could be performed with meticulous bleeding control and strictly following the transfusion indications.

배경: 수혈의 부작용은 널리 알려져 있으나, 대부분의 개심술에서 수혈이 시행되고 있다. 동종 수혈 없이 심장수술이 가능한 지에 대하여 알아보고자 본 연구를 시행하였다. 대상 및 방법: 2007년 1월부터 8월까지 다양한 혈액보존법을 적용하여 연속적으로 개심술을 시행한 환자 44명을 대상으로 심페기군(Group I, 17명)과 무심폐기군(Group II, 27명) 두 군으로 나누어 후향적 연구를 시행하였다. 혈액보존법은 수술 중 자가 혈액 채취(intraoperative autologous donation), 자가수혈기(cell saver), 역행적 자가 혈액 충전법(retrograde autologous priming), 기존 초여과법(conventional ultrafiltration), 변형 초여과법(modified ultrafiltration) 등을 사용하였고 술 후 항빈혈약을 복용시켰다. 무혈 수술 가능여부, 동종 수혈 원인, 적혈구 용적률의 변화, 술 후 출혈량 등 수술 결과를 분석하여 비교하였다. 두 군간 비교가 적당치 않은 항목은 혈액보존법 적용 전 2006년 수술한 환자를 대조군(49명) I, II로 하여 각각 비교하였다. 결과: 대상환자 44명 중 40명(90.9%)에서 무혈수술이 가능하였으며 각 군의 무혈 수술 성공률은 심폐기군 88.2% (15/17), 무심폐기군 92.6% (25/27)로 두 군간 차이는 없었다(p=NS). 수혈 원인은 술 후 출혈 2명, 술 중 출혈 1명, 원칙 적용 실수 1명이었다. 수술 결과 및 술 후 총 흉관 배액량(심폐기군 $417{\pm}359mL$, 무심폐기군 $451{\pm}237mL$)은 두 군간 차이가 없었으나(p=NS), 각각의 대조군 I, II에 비해 통계적으로 유의하게 배액량이 적었다(p<0.05). 심폐기군에서 최저 적혈구 용적률은 심정지액 주입된 직후로 $16.4{\pm}2%$였고 두 군 모두 술 후 2개월째 수술 전 수준으로 회복되었다. 결론: 본 연구에서는 수술 중 자가 혈액 채취, 수술 중 자가수혈기, 역행적 자가 혈액 충전법, 기존 초여과법, 변형 초여과법 등을 사용하여 90.9%의 환자에서 무혈 수술이 가능하였다. 다양한 혈액보존법의 복합 적용이 가장 중요하며, 수술 시의 세심한 지혈 과정 그리고 수혈 기준의 완화 등을 통해 무혈 수술이 가능하다.
