Abstract

Purpose : The purpose was to investigate the clinical considerations of patients affected by meconium aspiration syndrome (MAS) and the effect of suctioning through endotracheal intubation immediately after delivery on the prognosis of MAS. Methods : A total of 44 inpatients diagnosed as MAS in the Neonatal Intensive Care Unit (NICU) at Cheil Hospital were selected from January 2004 to June 2006. They were divided into two groups. In the early aspiration group (12 patients), suctioning through endotracheal intubation was performed according to the neonatal resuscitation program of the American Academy of Pediatrics and the American Heart Association because infants born through meconium-stained amniotic fluid (MSAF) were not vigorous after birth. In the early non-aspiration group (32 patients), endotracheal intubation was not performed because the infants born through MSAF were vigorous after birth. These two groups were analyzed retrospectively by medical records in the fields of clinical features, obstetric risk factors, complications, treatment, and duration of hospitalization. Results : There was no significant difference in mean gestational age, mean birth weight, sex, and delivery mode between the early aspiration group and the early non-aspiration group. Mean Apgar score of the early aspiration group both in 1 and 5 minute score was significantly lower than in the early non-aspiration group. Lengths of hospitalization and duration of mechanical ventilator care were longer in the early non-aspiration group, but there was no significant difference. Total duration of oxygen therapy was significantly longer in the early non-aspiration group than in the early aspiration group. Conclusion : In this study, the early non-aspiration group used surfactant more and had a longer duration of mechanical ventilator and hospitalization, but there was no significant difference. Total duration of oxygen therapy was significantly longer in the early non-aspiration group. Therefore, more detailed guidelines for vigorous infants born through MSAF are needed and we should study and follow up the long term prognosis of neurological complications of MAS.

목 적 : 태변 흡인 증후군에 이환된 환아의 임상적 고찰과 분만 직후의 기관내 삽관을 통한 태변 흡입이 태변 흡인 증후군의 예후에 미치는 영향을 알아보고자 하였다. 방 법 : 2004년 1월부터 2006년 6월까지 2년 6개월 동안 제일 병원 신생아 집중 치료실에 입원한 환아 중에서 태변 흡인 증후군으로 이환된 44명을 대상으로 하였고, 이중 출생 직후 활발하지 않아 신생아 소생술 지침에 따라 기관 삽관을 통하여 태변 흡인을 시행하였으나 태변 흡인 증후군으로 이환된 군(12명)과 출생 직후 활발하여 기관 삽관을 하지 않았으나 태변 흡인 증후군으로 이환된 군(32명)으로 분류하여 각 군의 임상적 특징, 산과적 위험인자, 동반 질환, 치료 방법, 입원 기간 등을 의무기록을 통하여 후향적으로 비교 분석 하였다. 결 과 : 태변 흡인 증후군으로 이환된 환아에서 조기 흡인군과 조기 비흡인군에서 평균 재태 연령, 평균 출생 체중, 성별, 분만 방식 등은 통계적으로 유의한 차이가 없었으나 평균 아프가 점수는 조기 흡인군에서 1분, 5분 모두에서 유의하게 낮았으며, 동반 질환으로는 지속성 폐동맥 고혈압(13.6%), 신생아 경련(9.1%), 기흉 및 기종격(6.8%)에서 높은 빈도로 나타났다. 인공 호흡기 치료는 35예(79.5%)에서 시행하였고, 고빈도 진동성 환기법으로 치료 받은 환아는 조기 비흡인군에서 1예 있었으며 폐계면 활성제 치료를 받았던 환아는 조기 흡인군에서 1예(8.3%), 조기 비흡인군에서 5예(15.6%)로 조기 비흡인군에서 많았으나 통계적인 의미는 없었다. 기계적 환기 요법의 치료 기간과 입원 기간은 조기 비흡인군에서 길었으나 통계적으로 유의한 차이가 없었으나 총 산소 치료 기간은 조기 비흡인군에서 통계적으로 의미있게 길었다. 결 론 : 본 연구를 통해 태변 흡인 증후군 환아의 조기 비흡인군에서 폐 계면 활성제의 사용이 많았고, 기계적 환기 요법 치료 기간, 입원 기간 등이 길었지만 통계적으로 유의한 차이는 없었으며, 총 산소 치료 기간은 통계적으로 조기 흡인군에 비하여 유의하게 길었던 것으로 조사되었다. 그러므로 태변 착색아 중에서 활발한 군에 대한 더 세부적인 지침이 필요하다고 사료되며, 신경학적 후유증의 장기 예후에 대한 더 많은 연구와 추적 관찰이 필요하다.
