초록

목 적 : 신생아 집중 치료의 발전으로 인해 저출생 체중아의 생존률은 많이 향상되었으나 장기간의 산소 보충이 필요한 미숙아 만성 폐질환자의 증가는 해결해야 할 문제이다. 산모의 융모양막염 및 신생아의 인공호흡기 치료가 만성 폐질환에 상당한 영향을 미칠 수 있는 것으로 알려져 있다. 이에 저자들은 만성 폐질환의 발생에 산모의 융모양막염 및 신생아의 인공호흡기 치료가 독립적 혹은 종속적으로 작용하는지를 알아보고자 하였다. 방 법 : 2000년 1월부터 2006년 12월까지 본원 신생아 중환자실에 입원한 재태 기간 36주 이하, 출생체중 1,500 g 이하의 환아 158례를 대상으로 융모양막염의 존재 여부와 인공호흡기 사용에 따른 만성 폐질환의 발생률을 병력지를 기초로 후향적으로 조사하였다. 결 과 : 대상 환아 총 158례 중 산모의 융모양막염 양성은 50례(31.6%), 음성은 92례(58.2%), 생검을 통한 조직학적인 검사가 이루어지지 않은 경우는 16례(10.1%)였다. 융모양막염 유무와 만성 폐질환 발생 간에 유의한 상관관계가 없었으며(P=0.735), 융모양막염이 있고 인공호흡기를 사용한 36례 중 15례(41.7%)에서 만성 폐질환이 발생하였으며 인공호흡기를 사용하지 않은 14례 중 4례(28.6%)에서 만성 폐질환이 발생하였다(P=0.018). 융모양막염이 없는 그룹에서도 인공호흡기를 사용한 73례 중 32례(43.8%)에서 만성 폐질환이 발생하였고 인공호흡기를 사용하지 않은 19례 중 1례(5.3%)에서 만성 폐질환이 발생하여(P=0.002), 융모양막염 유무보다는 인공호흡기 사용이 만성 폐질환 발생에 영향을 미친 것으로 보여진다. 다중회귀분석에서도 인공호흡기 사용(OR=7.409, 95% CI=2.532-21.681)과 패혈증(OR=4.897, 95% CI=1.227-19.539)이 각각 만성 폐질환 발생에 영향을 미치는 것으로 나타났고 산모의 융모양막염은 OR=0.461, 95% CI=0.201-1.059로 만성 폐질환 발생에 영향을 미치지 못하는 것으로 나타났다. 결 론 : 인공호흡기의 사용, 패혈증이 만성 폐질환의 발생과 유의한 상관관계가 있었으며, 산모의 융모양막염 자체가 만성 폐질환의 발생에 직접적으로 영향을 줄 가능성은 낮은 것으로 나타났다.

Purpose : Advances in neonatal intensive care have improved the survival rate of low-birth-weight infants, but mild bronchopulmonary dysplasia (BPD) with the accompanying need for prolonged oxygen supplement remains problematic. Maternal chorioamnionitis and neonatal ventilator care affect the development of BPD. This study aimed to examine whether maternal chorioamnionitis or neonatal ventilator care affect the development of BPD dependently or independently. Methods : We performed a retrospective study of 158 newborn infants below 36 weeks of gestational age and 1,500 gm birth weight admitted to the neonatal intensive care unit of Daegu Fatima Hospital between January 2000 and December 2006. We analyzed the incidence of BPD according to maternal chorioamnionitis and neonatal ventilator care. Result : Histologic chorioamnionitis was observed in 50 of 158 infants (31.6%). There were no significant differences in the development of BPD (P=0.735) between the chorioamnionitis (+) and chorioamnionitis (-) groups. In the multiple regression analysis, ventilator care (OR=7.409, 95% CI=2.532-21.681) and neonatal sepsis (OR=4.897, 95% CI=1.227-19.539) affected the development of BPD rather than maternal chorioamnionitis (OR=0.461, 95% CI=0.201-1.059). Conclusion : Ventilator care or neonatal sepsis may play a role in the development of BPD rather than maternal chorioamnionitis.
