[Dataset] IS MINIMISING WASTE VOLUME FOR DRAWING BLOOD SAMPLES IN CRITICALLY ILL PATIENTS FEASIBLE?

Drawing blood samples through a central venous catheter is a customary practice in Intensive Care Units. It is recommended to discard a volume of waste blood to avoid interference in the results. Decreasing this volume could contribute to minimising iatrogenic anaemia in our patients.经中心静脉导管（Central Venous Catheter）采集血样是重症监护病房（Intensive Care Unit, ICU）中的常规临床操作。临床推荐弃去一定体积的预抽无效血液，以避免其对检验结果造成干扰。缩减该弃血量，可有助于降低患者发生医源性贫血（Iatrogenic Anemia）的风险。
