Application value of low molecular weight heparin subcutaneous injection positioning card in preventing complications in patients
低分子肝素皮下注射定位卡在预防患者并发症中的应用价值

摘要

目的 探讨一种改良式低分子肝素皮下注射定位卡在预防低分子肝素注射患者并发症中的应用价值。方法 选取2023年9月至2024年2月在我区接受低分子肝素皮下注射治疗的病人100例，采用随机数字表法将病人分为2组各50例。对照组采用传统目测定位法进行低分子肝素皮下注射穿刺点定位，干预组则使用改良式低分子肝素注射定位卡进行穿刺点定位，通过比较两组注射部位准确率、疼痛情况及皮下出血情况，对两组患者的应用效果进行观察比较。结果 对照组皮下注射低分子肝素 390 次，干预组为417 次。其中干预组注射部位准确率高达100%，远超对照组的26.2%；干预组穿刺点中重度疼痛率16.6%，低于对照组的76.7%，差异显著（P<0.05）；干预组皮下出血发生率51.6%，低于对照组的94.4%，差异显著（P<0.05）。结论 行皮下注射低分子肝素治疗者，给予低分子肝素注射定位卡辅助定位，可准确定位，缓解穿刺点疼痛，降低皮下出血风险，具备推广价值。

Abstract

Objective To investigate the application value of a modified low molecular weight heparin subcutaneous positioning card in preventing complications in patients with low molecular weight heparin injection.
Methods A total of 100 patients who received subcutaneous injection of low molecular weight heparin in our district from September 2023 to February 2024 were selected and divided into 2 groups with 50 patients in each group by random number table method. The traditional visual localization method was used to locate the puncture points of low molecular weight heparin subcutaneous injection in the control group, and the modified low molecular weight heparin injection locator card was used to locate the puncture points in the intervention group. By comparing the injection site accuracy, pain and subcutaneous bleeding of the two groups, the application effects of the two groups were observed and compared.
Results The subcutaneous injection of low molecular weight heparin was 390 times in the control group and 417 times in the intervention group. The accuracy of injection site in the intervention group was 100%, far higher than 26.2% in the control group. The rate of moderate to severe pain at puncture point in the intervention group was 16.6%, lower than that in the control group (76.7%), and the difference was significant (P<0.05). The incidence of subcutaneous hemorrhage in the intervention group was 51.6%, which was significantly lower than that in the control group (94.4%) (P<0.05).
Conclusion   For patients treated with subcutaneous injection of low molecular weight heparin, low molecular weight heparin injection locator card can be given to assist location, which can accurately locate, relieve pain at puncture point and reduce the risk of subcutaneous bleeding, and has the value of popularization.
