Comparison of modified versus conventional injection techniques of low-molecular-weight heparin in elderly

OBJECTIVE: To analyze the clinical values of modified injection of low-molecular-weight heparin in reducing subcutaneous bleeding and pain. METHODS: Two hundred and sixty patients with cerebral infarction, acute myocardial infarction or pulmonary embolism who underwent subcutaneous injection of low-molecular weight heparin in the hospital between December 2015 and December 2016 were selected. They were randomly divided into a control group and a research group, 130 each. Patients in the control group were given conventional injection, while patients in the research group were given modified injection. The occurrence of subcutaneous bleeding and pain was observed and compared between the two groups. RESULTS: The incidence of subcutaneous hemorrhage in the research group was 46.9%, significantly lower than 83.1% in the control group, and the difference had statistical significance (P<0.05). Twenty-six patients in the control group had severe pain, which was much more than 5 patients in the research group, and the difference was statistically significant (P<0.05). The number of cases of severe hemorrhage in the control group was significantly larger than that of the research group (31 vs. 3), and the difference was also statistically significant. CONCLUSION: Modified low-molecular weight heparin injection can effectively reduce the incidence of bleeding and pain, which is beneficial to the compliance and quality of life of elder patients.
