초록

패혈증은 흔하고 위중한 질환이다. 혈액배양은 패혈증을 진단하는데 필수적인 검사이다. 자동화 혈액배양 장비가 도입된 지 수 십년이 되었지만, 혈액배양의 올바른 활용과 질 향상에 대해서는 활발한 토의가 이루어지지 못하였다. 저자는올바른 채혈 방법, 정도관리 지표, 이미 항균제는 사용한 경우, 늦은 장비 투입, 장비 검출시간, 반복 배양, 카테터연관혈류감염 및 새로운 기술 등 다양한 이슈에 대해서 살펴보았다. 앞으로도 혈액배양 장비는 더욱 자동화되고 빨라지겠지만, 질 향상은 잘 교육된 의료 종사자에 의해 이루어져야 한다.

Abstract

Sepsis is a common and critical illness diagnosed via blood culture. Although a continuous blood culture monitoring system was introduced several decades ago, optimal utilization and improvement of blood culture methods has not been discussed recently. The author describes several blood culture-related topics including optimal blood collection procedures, quality control indicators, prior antibiotic treatment, delayed entry, time to detection, follow-up blood culture, catheter-related bloodstream infection, and new techniques to rapidly identify microorganisms. Although rapid, automatic blood culture systems are likely to be developed in the near future, quality improvement should be accomplished by well-educated medical personnel.
