Low molecular weight heparin modified injection method in patients with acute myocardial infarction application / 中国实用护理杂志

ABSTRACT

Objective@#To investigate the application of low molecular weight heparin modified injection in the nursing of patients with acute myocardial infarction.@*Methods@#A total of 90 patients with myocardial infarction who underwent subcutaneous injection of low molecular weight heparin from May 2017 to May 2018 were enrolled in the study. The patients were divided into the control group and the observation group according to the different injection and treatment methods. The control group used the traditional injection method of low molecular weight heparin, and the observation group used the low molecular weight heparin modified injection method. Forty-five patients were observed and compared for the degree of subcutaneous hemorrhage, incidence of induration and pain.@*Results@#The incidence of subcutaneous induration and subcutaneous hemorrhage in the observation group were 10.16% (64/630) and 19.84% (125/630), respectively. The control group was 16.19% (102/630) and 31.11% (196/630), respectively. The difference between the groups was statistically significant (χ2=10.019, 21.073, both P<0.05). The pain score of the observation group was 1.29±0.21, and the control group was 1.86±0.28. The difference between the two groups was statistically significant (t=40.877, P<0.05); the subcutaneous mild, moderate, and severe bleeding in the observation group were 17.30% (109/630), 2.54% (16/630), and 0, respectively, and the control group was 21.90% (138/). 630), 8.41% (53/630), 0.79% (5/630), the difference between the two groups was statistically significant (χ2=4.235, 20.990, 4.019, all P < 0.05).@*Conclusions@#Low molecular weight heparin modified injection method for myocardial infarction patients can effectively reduce the incidence of subcutaneous hemorrhage and induration, reduce the degree of subcutaneous hemorrhage and pain, suitable for clinical promotion.
