초록

목 적 : 극소 저출생 체중아에서 경구 수유가 불가능한 기간 동안 총정맥영양을 시행할 목적으로 경피 중심정맥 도관(percutaneous central venous catheter, PCVC)을 시술하는데 이의 가장 흔한 합병증인 패혈증은 신생아 이환율과 사망률을 높일 수 있다. 본 연구는 1,500 g 미만의 극소 저출생 체중아에서 시행한 PCVC의 유용성 및 도관과 관련된 합병증 발생을 알아보고자 하였다. 방 법 : 1998년 1월부터 2003년 12월까지 신생아 집중치료실에 입원한 1,500 g 미만의 저출생 체중아 중 PCVC를 시행했던 32명을 연구군(1,000 g 미만 17명, 1000-15,00 g 15명)으로 하였고, PCVC를 하지 않은 24명(1,000 g 미만 9명, 1,000-1,500 g 15명)을 대조군으로 하였다. 연구군과 대조군 간에 체중증가 양상과 2,000 g이 되는 시기를 비교하였고, 입원기간 동안 체중증가에 영향을 줄 수 있는 이환 질환 및 도관 관련 합병증을 조사하였다. 결 과 : 연구군과 대조군의 특징을 보면 출생체중, 재태주령, Apgar 점수, 호흡곤란 증후군, 인공환기 기간, 튜브영양을 처음 시작하는 시기, 경구수유 시작 시기 및 시작 시의 체중, 튜브영양에서 경구수유까지 걸린 기간, 총 정맥영양을 시작한 생후 일수와 기간, 종료시 체중 및 2,000 g에 도달하는 시기에 의미 있는 차이는 없었고, 총 정맥영양 기간만 연구군에서 $25.5{\pm}10.78$일로 대조군 $39.9{\pm}9.87$일에 비해 의의있게 길었다(P<0.001). 이환 질환 및 합병증에 있어서 호흡곤란 증후군, 만성 폐질환, 동맥관 개존, 뇌실내 출혈, 괴사성 장염, 패혈증, 골연화증 및 담즙 정체 발생빈도는 두 군간에 차이가 없었고 뇌실내 출혈만 연구군에서 87.5%로 대조군(58.3%)에 비해 의의있게 높았다. 연구군과 대조군을 1,000 g 미만과 1,000-1,500 g으로 나누어 비교해 본 결과, 연구군에서 대조군에 비해 1,000 g 미만에서는 패혈증 빈도가 의의있게 높았으며(35.3% vs 0%, P<0.05), 1,000-1,500 g에서는 뇌실내 출혈 빈도가 의의있게 높았고( 86.7% vs 40%, P<0.05), 2,000 g에 도달하는 시기도 오히려 늦었다. 결 론 : 경피 정맥도관술을 실시한 연구군에서 총 정맥영양기간이 길었지만 체중 증가에는 효과가 없었고 오히려 1,000 g 미만에서는 패혈증 빈도가 그리고 1,000-1,500 g에서는 뇌실내 출혈의 빈도가 높았기에 극소 저출생 체중아에서 경피 정맥 도관을 통한 총 정맥영양요법 시에는 무균적 조작과 수액 공급 속도 등에 더 주의를 기울여야 될 것으로 사료되었다.

Purpose : The administration of total parenteral nutrition(TPN) has become a standard procedure in the management of nutritionally deprived and critically low birth weight neonates. Sepsis remains the most frequent serious complication during TPN, resulting in increased morbidity, mortality and health care costs. This study was performed to evaluate the clinical efficacy and complications of percutaneous central venous catheterization(PCVC) in very low birth weight infants. Methods : A total of 56 very low birth weight infants below 1,500 g during the period from January 1998 to December 2003 were enrolled and their medical records reviewed. Study group(n=32) included the babies who had undergone PCVC and a control group(n=24) included babies who had not undergone PCVC. We compared the study group with the control group for factors such as subject characteristics and catheter-related complications. Results : There was no difference in subject characteristics, such as birth weight, gestational week, respiratory distress syndrome, duration of ventilator therapy, duration from tube to complete oral feeding, days at TPN and its total duration, body weight at discontinuation of TPN and the days taken to reach to 2,000 g. However, the morbidity rate due to patent ductus arterious, chronic lung disease, necrotizing enterocolitis, osteopenia, cholestasis, and sepsis showed no difference. The study group with infants below 1,000 g showed a higher incidence of sepsis compared to the control group of the same weight group. The study group with infants between 1,000 to 1,500 g showed significantly higher incidences of intraventricular hemorrhage and took longer reach the a body weight of 2,000 g. Conclusion : Considering the high incidence of sepsis in the PCVC group, every attempt should be made to minimize the length of TPN therapy and encourage early enteral feeding. We also recommend the use of PCVC carefully in patients requiring prolonged nutritional support.
