Venous Hematocrit: Caveats to Informing Blood Volume and Relative Risk in Chronic Heart Failure [PDF]

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Venous hematocrit (vHct) is commonly used to inform blood volume (BV) status and stratify cardiovascular risk. However, vHct defines a percentage of red blood cells (RBCs) to total BV; therefore, similar vHcts can reflect significantly ...

Educational Intervention to Improve Blood Culture Indicators in a Secondary-Care Hospital

open access: yesAnnals of Clinical Microbiology, 2021
배경: 혈액배양은 패혈증을 진단하는데 필수적인 검사이다. 혈액배양 시 충분한 양의 혈액 채취가 중요하며, 질 향상을 위해서는 주기적으로 채혈량 모니터링과 피드백이 필요하다.방법: 2차 의료기관에서 혈액배양 시 고려해야 할 점에 대해서 채혈전담자를 대상으로 교육을 시행하였다.
