중심정맥 도관 관련 감염의 역학 고찰 = Epidemiology of central venous catheter related bloodstream infections in pediatric patients

다국어 초록 (Multilingual Abstract)

Purpose : The purpose of this study is to investigate the pathogens of central venous catheter-related blood stream infections and search for the association among the insertion site, the duration and the underlying conditions with the prevalence of central venous catheter-related blood stream infections under 15 years old.
Methods : A retrospective study was performed from Jan, 2003 to Dec, 2003 in Severance Hospital on 112 patients who undertook central venous catheter insertions.
Results : We examined 112 patients who undertook central venous catheter insertion. The mean age of patients was 4.77±4.12 years old. Coagulase negative Staphylococci was the most common organism of central venous catheter-related blood stream infections accounting for 33.9 percent, followed by Eenterococcus faecium(9.3 percent), and Staphylococcus aureus(7.5 percent), The most common insertion site was the right femoral vein, followed by the right jugular vein and the left femoral vein. The mean insertion period was 14.17±12.00 days.
Conclusion : Central venous catheter-related blood stream infections were not only related to the underlying conditions, but also to the insertion site. We need to study the clinical importance of coagulase negative Staphylococci as it is part of the normal flora of the skin. In future, more studies are needed to take preventive measures and improve treatment methods.

목 적 : 15세 이하 소아의 중심정맥 도관 관련 감염의 임상적 검토를 통해 원인균을 밝히고 삽입위치, 유치기간, 기저 질환 등에 따른 감염 발생과의 연관성을 조사하고자 하였다. 방 법 : 2003년 1월 1일부터 12월 31일까지 연세의료원에 입원하여 중심정맥 도관을 삽입술을 시행 받은 15세 이하 112명을 대상으로 의무기록의 후향적 검토를 시행하였다.결 과 : 총 139례의 배양검사가 시행되었으며, 45례(34.2%)에서 중심정맥 도관 감염이 발생했고(Table 1), 53가지 균주가 동정되었다. 발생 균주는 그람 양성인 coagulase negative Staphylococcus가 18례(33.9%)로 가장 많았고 Enterococcus faecium 5례(9.3%), Staphylococcus aureus 4례(7.5%), Enterococcus faecalis 2례(3.8%) 순으로 발생했고, 그람 음성은 Acinetobacter anitratus 3례(5.7%), Pseudomonas aeruginosa 3례(5.7%), Klebsiella pneumonia 2례(3.8%) 순이었으며, 이외 Yeast 4례(7.5%), Candida albicans 3례(5.7%), Acinetobacter species, α-streptococcus, Candida species, Citrobacter freundii, Diphtheroid 각 1례(1.9%)의 빈도를 보였다. 삽입 부위는 우측 대퇴 정맥이 72례로 가장 많았고, 우측 경정맥 21례, 좌측 대퇴 정맥 20례였다. 중심정맥 도관 삽입 유치기간은 평균 14.17±12.00일이었으며, 감염이 발생하지 않은 군은 13.19±9.10일, 감염이 발생한 군은 15.98±15.98일로 두 그룹 사이에 관련성이 있을 것으로 판단된다(P=0.06). 중심정맥 도관 삽입 환자 중 9명이 사망하였는데 4명에서 중심정맥 도관 감염이 있었으나, 중심정맥 도관 감염과 사망과는 통계적으로 유의한 관계는 없었다(P>0.05).
