Abstract

Background: Remarkable progress has recently been made in achieving successful early repair of congenital heart disease with using cardiopulmonary bypass in the neonatal period. The aim of this study is to evaluate our short-term outcomes for performing neonatal cardiac surgery under extracorporeal circulation. Material and Method: Fifty five neonates underwent open heart surgery from February 2002 to December 2007. The mean ages and body weight was 13.5 days. and 3.2 kg, respectively. The diagnoses of the patients were transposition of the great arteries (14), total anomalous pulmonary venous connection (7), large ventricular septal defect (VSD) (7), coarotation of the aorta with VSD (6), interrupted aortic arch (5) and others (16). Result: Six patients had difficulties being weaned from extracorporeal circulation. Four patients left the operating room with an open sternum. Low cardiac output syndrome and acute renal insufficiency were observed in 3 patients each, respectively. Post-operative complications were observed in 27 patients (49.1%). The postoperative mortality was 12.7% (7 patients); 5 patients experienced early hospital death and 2 experienced late death (2). Conclusion: In our hospital, early surgical repair with extracorporeal circulation in neonates was feasible with tolerable mortality. Further follow-up required to establish the long-term survival and complications.

배경: 최근 신생아기에 선천성 심질환을 심폐우회술을 이용해서 성공적인 조기 교정을 하는데 있어서 상당한 진전이 이루어졌다. 이 연구의 목적은 체외순환 하에서의 신생아 개심술의 조기 성적을 알아보는 것이다. 대상 및 방법: 2002년 2월부터 2007년 12월까지 55명의 신생아에서 개심슬을 시행하였다. 술전 상태, 수술 방법, 술후 이병률과 사망률을 알아보기 위해서 후향적인 조사를 하였다. 평균 연령과 체중은 각각 13.5일, 3.2 kg이었다. 진단은 대 혈관전위 14예, 전폐정맥연결이상 7예, 큰 심실 중격결손 7예, 심실중격결손이 동반된 대등맥축착 6예, 대동맥궁단절 5예 및 기타 16예로 분포되어 있었다. 결과: 평균 대동맥차단시간은 62.2분이었다. 심도 저체온하 완전순환정지(평균 기간 22.5분)는 6예에서 적용되었다. 술후 체외순환의 이탈이 어려웠던 경우가 6예 있었다. 흉골을 봉합하지 못하고 수술실을 나왔던 환아가 4명 있었다. 저심박출증과 급성 신부전이 각각 3예씩 있었다. 평균 인공 호흡기 사용기간은 70.5시간, 평균 집중치료실 재원기간은 14.9일이었다. 술후 합병증은 27명(49.1%)에서 나타났다. 술후 평균 추적관찰 기간은 23.8개월이었다. 술후 사망률은 12.7% (7예)였는데, 조기 병원사망예가 5예, 만기 사망예가 2예였다. 결론: 최근 본원에서의 체외순환을 이용한 신생아기 개심술의 조기 성적은 비교적 양호하였다. 향후 장기 생존과 만기 합병증을 알아보기 위해서 더 긴 추적 관찰을 요한다.
