Study on methods of reducing hemolysis before blood specimen examination
降低血液标本检验前发生溶血情况的方法研究

摘要

目的 探讨降低血液标本检验前发生溶血情况的方法。方法 本次研究将采用抽样调查和分组研究的方法，2020年1月到9月实行常规血液标本管理，标本数量为200例，设置为对照组；2020年10月到2021年6月对血液标本实施品管圈活动，血液标本数量为200例，设置为实验组。收集两组血液标本检验前发生溶血的情况，对比常规管理和品管圈活动管理的优劣。同时再对提供血液标本的400例患者进行问卷调查，实验组患者200例，对照组患者200例，收集患者对护士工作的满意度。结果 经过对比可知，实施品管圈活动的实验组血液标本溶血概率明显低于常规管理的对照组（P＜0.05）；实验组患者对护士工作的满意程度也有所提升，远高于对照组（P＜0.05）。结论 血液标本检验前出现溶血将对血液检测造成不良影响，但在采用品管圈活动后，血液标本溶血率显著降低，大大提升了患者对护士采血、检验等工作的满意程度。

Abstract

Objective To explore the method of reducing hemolysis before blood specimen examination.
Methods The method of sampling survey and grouping study was adopted in this study. Routine blood specimen management was carried out from January to September 2020, and 200 samples were set as the control group. From October 2020 to June 2021, quality control circle activities were carried out on blood samples, and 200 blood samples were set as experimental group. The hemolysis of the two groups of blood samples before testing was collected, and the advantages and disadvantages of routine management and quality control circle activity management were compared. At the same time, another 400 patients who provided blood samples were surveyed by questionnaire, 200 patients in the experimental group and 200 patients in the control group, to collect patients' satisfaction with the work of nurses.
Results The hemolysis probability of blood samples in the experimental group was significantly lower than that in the control group (P < 0.05). The satisfaction degree of nurses in the experimental group was also improved, much higher than that in the control group (P < 0.05).
Conclusion  s Hemolysis before blood sample examination will have adverse effects on blood test, but after the use of quality control circle activities, the hemolysis rate of blood sample is significantly reduced, which greatly improves the patients' satisfaction with the work of blood collection and examination of nurses.
