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.
