초록

목적: 최근 미숙아에서 동맥관 결찰 술 후 설명할 수 없는 혈역동학적 불안정성에 대한 보고가 되고 있어 극소저체중아에서 동맥관 결찰술 후 발생하는 혈역동학적 불안정성의 위험 요인 및 임상 양상에 대해 알아보고자 하였다. 방법: 2002년 1월부터 2008년 12월까지 고려대학교 의료원내 3개 병원의 신생아 중환자실에서 치료 받은 재태 32주 미만의 극소저체중출생아에서 동맥관 결찰술을 시행 받은 환아 18명을 대상으로 하여 의무기록을 후향적으로 조사, 분석하였다. 수술 중 또는 수술 후 문제로 인한 혈역동학적 불안정성 이외에 설명할 수 없는 심폐 기능의 저하로 인공 호흡기 의존도의 증가와 혈압의 하강 등이 관찰된 환자를 혈역동학적 불안정군(hemodynamic instability group, HI)으로 정의하였다. 결과: 연구에 참여한 18명의 환아들의 재태 주수는 $27^{+6}{\pm}1^{+6}$주, 평균 출생 체중은 951${\pm}$245 g이었다. HI군은 7명(7/18, 39%)이었으며 혈역동학적 안정군(hemodynamic stability group, HS)은 11명(11/18, 61%)이었다. HS군에 비해 HI군은 출생 체중(1,033${\pm}$285 g vs. 821${\pm}$126 g, P=0.048)과 수술 시 체중(1,195${\pm}$404 g vs. 893${\pm}$151 g, P=0.042)이 작았으며, 재원기간이 길었고 (105${\pm}$29 vs. 141${\pm}$39, P=0.038) 심한 기관지 폐 이형성증의 빈도가 높았고(no/mild/moderate/severe, 2/5/2/2 vs. 0/1/2/4, P=0.038) 수술 전 $FiO_2$의 농도가 높았다(0.29${\pm}$0.06 vs. 0.38${\pm}$ 0.09, P=0.02). 18명 중 HS군에서 1명의 환아가 동맥관 결찰술 후 94일 째 패혈증으로 사망하였다. 결론: 극소저체중아에서 동맥관 결찰술 후 혈역동학적 불안 정성이 발생한 경우는 약 39%였다. 작은 출생 체중과 수술 시 체중, 수술 전 높은 산소 분압의 산소 투여가 동맥관 결찰술 후 혈역동학적 불안정성 발생의 위험인자가 될 수 있으며 아울러 혈역동학적 불안정성은 기관지 폐 이형성증의 유병률 및 중증도와 재원기간을 증가시킬 수 있음을 확인하였다.

Purpose: Recently, after patent ductus arteriosus (PDA) ligation in preterm infants, unexplained hemodynamic instabilities are reported. To determine the incidence, risk factors and clinical manifestations of hemodynamic instability after PDA ligation in very low birth weight (VLBW) infants. Methods: This retrospective multicenter study enrolled 18 VLBW infants who underwent PDA ligation from January 2002 to February 2008. Hemodynamic instability defined as unexplained cardiopulmonary dysfunction with increased dependency on mechanical ventilation and decreased blood pressure. Results: The mean gestational age and birth weight (BW) of all infants were $27^{+6}{\pm}1^{+6}$ weeks and 951${\pm}$245 g. Hemodynamic instability group (HI) included seven infants (39%) and hemodynamic stability group (HS) included 11 infants (61%). Compared to HS, HI had lower BW (1,033${\pm}$285 g vs. 821${\pm}$126 g, P=0.048) and weight on operation day (1,195${\pm}$404 g vs. 893${\pm}$151 g, P=0.042), longer hospital days (105${\pm}$29 vs. 141${\pm}$39, P=0.038), more severe bronchopulmonary dysplasia (BPD), (no/mild/moderate/severe, 2/5/2/2 vs. 0/1/2/4, P=0.038) and higher preoperative $FiO_2$ (0.29${\pm}$0.06 vs. 0.38${\pm}$0.09, P=0.02). One case of mortality due to sepsis, which was not associated with ligation, was observed among HS. Conclusion: The incidence of hemodynamic instability after PDA ligation in VLBW infants was 39%. Low BW, low weight on operation day and preoperative high $FiO_2$ might be risk factors of hemodynamic instability after PDA ligation in VLBW infants. The hemodynamic instability could increase the severity of BPD and hospital days.
