■医源性失血是新生儿贫血的重要原因。在这项研究中,开发了一个电子表格工具来减少血液收集,为预防新生儿医源性失血提供新思路。
■基于血细胞比容,最小测试体积和死体积,一个新的工具是计算最小血液收集量和测试组合所需的容器数量。我们从厦门市妇幼保健院收集了2022年10月至2023年10月的数据进行分析和验证。
■今年,新生儿科共有16,434例患者和13,696例血浆/血清学样本.其中,有8个大于1%的测试组合,共9490个样品。根据医院手册,建议采血量为27,534毫升和9490个容器。通过对这一工具的分析,总采血量为8864.77ml,向上容器的标记数量(最接近计算的血液收集量)为10301毫升,集装箱数量为8835,下降了67.8%,分别为62.58%和6.9%。此外,如果无法提前获得血细胞比容信息,并且计算为高血细胞比容为0.8,则建议采血量为14334.3ml,向上标记的容器标记量为17340毫升,分别下降47.9%和37.02%。
■我们开发了一种辅助工具,可以以精细和个性化的方式管理新生儿血液样本收集,并可以通过参数修改在不同的实验室仪器之间应用。
UNASSIGNED: Iatrogenic blood loss is an important cause of neonatal anemia. In this study, a spreadsheet tool was developed to reduce blood collection, providing a new idea for the prevention of iatrogenic blood loss in newborns.
UNASSIGNED: Based on hematocrit, minimum test volume and dead volume, a new tool was to calculate the minimum blood collection volume and the number of containers required for the test portfolio. We collected data from October 2022 to October 2023 from Xiamen Maternal and Child Health Hospital for analysis and validation.
UNASSIGNED: During this year, there were 16,434 patients and 13,696 plasma/serological samples in the neonatology department. Among them, there were 8 test combinations of greater than 1%, and 9490 samples in total. According to the hospital manual, the recommended amount of blood collection is 27,534 ml and 9490 containers. Through the analysis of this tool, total blood collection was 8864.77 ml, marked qnantity of upward containers (closest level to the calculated blood collection volume) was 10301 ml, and the amount of containers was 8835, which decreased by 67.8%, 62.58% and 6.9% respectively. Besides, if the hematocrit information cannot be obtained in advance and the high hematocrit is calculated as 0.8, the recommended amount of blood collection is 14334.3 ml, and the marked amount of the upward container markering is 17340 ml, decreasing by 47.9% and 37.02% respectively.
UNASSIGNED: We have developed an auxiliary tool that can manage neonatal blood specimen collection in a fine and personalized way and can be applied among different laboratory instruments by parameters modification.
