Abstract

Purpose : The increased survival of preterm infants in the neonatal intensive care unit recently has resulted in an increased frequency of bronchopulmonary dysplasia (BPD), especially with atypical forms. However, there have been few studies compairing classic and atypical BPD. The aim of this study was to investigate the differences between these two types of BPD. Methods : Infants with a gestational age less than 32 weeks born at the Seoul National University Hospital and Bundang Seoul National University Hospital from May 2004 to April 2007 were included. The data were categorized in 2 groups, classic and atypical BPD. We determined the incidence of BPD, and compared perinatal factors and postnatal managements between two groups. Results : Among 260 study subjects, 141 (54.2%) infants had BPD. Classic BPD infants were 64 and atypical BPD infants were 77. Comparison of differences between 2 groups, classic BPD infants were associated with respiratory distress syndrome, patent ductus arteriosus, intrauterine growth restriction, more high-frequency ventilator (HFV) use, low 1 and 5 minute Apgar scores. Atypical BPD infants were associated with antenatal steroid use, maternal premature rupture of membrane and chorioamnionitis (CAM). In multivariate analysis, more HFV use was associated with classic BPD. Antenatal steroid use, clinical CAM and histological CAM were associated with atypical BPD. Conclusion : The results of this study showed that antenatal factors (antenatal steroid use, clinical CAM, histological CAM) were associated with atypical BPD and postnatal factors (HFV used more) were associated with classic BPD. Further studies are needed for prevention and treatment of BPD.

목 적 : 최근 신생아중환자실에서 생존률이 향상됨에 따라서 기관지폐이형성증의 발생률이 증가하고 있고, 그 중에서도 특히 비전형적 기관지폐이형성증의 발생률이 증가하고 있다. 그러나, 전형적인 기관지폐이형성증 환아와 비전형적 기관지폐이형성증 환아의 비교 연구는 많지 않다. 이에 저자들은 두 군간의 차이점을 알아보고자 본 연구를 시행하였다. 방 법: 2004년 5월부터 2007년 4월까지 서울대학교병원과 분당 서울대학교병원에서 출생하여 신생아중 환자실에 입원한 월경 후 주령 32주 미만인 환아를 대상으로 하였고, 이를 전형적인 군과 비전형적인 군으로 나누었다. 그리고, 기관지 폐이형성증의 발생률을 조사하고, 전형적인 군과 비전형적인 군에서 주산기적 요인과 출생 후 치료를 비교하였다. 결 과:총 연구 대상은 260명이었고 이 중 141명(54.2%)이 기관지폐이형성증으로 진단되었다. 이 중 전형적 기관지폐이형성증은 64명, 비전형적 기관지폐이형성증은 77명이었다. 전형적 기관지폐이형성증 환아에서 신생아 호흡곤란 증후군, 동맥관 개존증, 자궁내 성장지연이 더 많이 동반되었고, 1분과 5분 Apgar 점수가 낮았고, 고진동 인공환기기 사용이 더 많았다. 비전형적 기관지폐이형성증 환아에서는 산전 스테로이드 사용이 더 많았고, 조기 양막파수, 임상적 융모양막염과 병리학적 융모양막염의 동반이 더 많았다. 다중 로지스틱 회귀분석을 시행하였을 때 고진동 인공환기기 사용은 전형적 기관지폐이형성증 환아에서 독립변수였고, 산전 스테로이드 사용, 임상적 융모양막염과 병리학적 융모양막염은 비전형적 기관지폐이형성증 환아에서 독립변수였다. 결 론:본 연구에서는 산전 요인(산전 스테로이드 사용, 임상적 융모양막염, 병리학적 융모양막염)은 비전형적인 기관지폐이형성증과 유의한 관계를 보였고, 산후요인(더 흔한 고진동 인공환기기 사용)은 전형적 기관지폐이형성증과 유의한 관계를 보였다. 앞으로, 위와 같은 임상 연구들을 바탕으로 기관지폐이형성증의 예방과 치료에 대한 더 많은 연구가 필요하리라 생각된다.
