背景：新生儿脓毒症是新生儿重症监护病房死亡和发病的主要原因。采血量的培养仍然是分离微生物的最重要的因素之一。目的评价干预对供培养的血容量的影响，并确定由采血师确定的影响血容量的因素。方法在接种前和接种后立即称重培养瓶，测定血培养量。3个月的干预前审计显示，在126/130个样本（96.9%）中，提交的血量不理想。制定了多种干预措施，并在接下来的9个月内监测了量。结果共纳入血培养样本637份，干预前130份，干预后507份。干预后，次优体积样本从96.9%（126/130个样本）减少到25%（126/507个样本），p
Background Neonatal sepsis is the leading cause of mortality and morbidity in neonatal intensive care units. The volume of blood taken for culture remains one of the most important factors in isolating microorganisms.Objectives To evaluate the impact of the intervention on the blood volume submitted for culture and to identify factors influencing the volume as determined by the phlebotomist.Methods Blood culture volume was determined by weighing the culture bottle before and immediately after blood inoculation. A 3-month preintervention audit revealed that in 126/130 samples (96.9%), the volume of blood submitted was suboptimal. Multiple intervention measures were instituted, and volume was monitored over the next 9 months.Results 637 blood culture samples were included in the study, 130 were in preintervention and 507 were in postintervention epochs. Following the intervention, suboptimal volume samples reduced from 96.9% (126/130 samples) to 25% (126/507 samples), p
