The feasibility of collecting smaller blood volumes during phlebotomy for diagnostic laboratory testing was evaluated by substituting pediatric-size for adult-size blood collection tubes. The volume of blood drawn with the use of pediatric-size tubes from 41 patients in an intensive care unit (120.2 mL total; 32.2 mL/day) was 46.8% lower than in that of a control population for which adult-size tubes were used (226.1 mL total; 55.6 mL/day). Sufficient blood was available for performance of all laboratory tests ordered at the time of the phlebotomy. Although substituting pediatric-size tubes does not address the problem of excessive use of laboratory tests, smaller tubes may reduce the severity of phlebotomy-induced anemia in adults without compromising laboratory test procedures.
通过用儿科尺寸的采血管替代成人尺寸的采血管，评估了在静脉穿刺采血时采集较少量血液用于诊断实验室检测的可行性。在重症监护病房中，使用儿科尺寸采血管从41名患者身上采集的血液量（总计120.2 mL；每天32.2 mL）比使用成人尺寸采血管的对照人群（总计226.1 mL；每天55.6 mL）低46.8%。有足够的血液可用于在静脉穿刺采血时所开的所有实验室检测。虽然使用儿科尺寸的采血管不能解决实验室检测过度使用的问题，但较小的采血管可能会减轻成人静脉穿刺引起的贫血的严重程度，而不会影响实验室检测程序。
