Abstract:Objective To investigate the application of Z-type injection in pregnant women who injected insulin subcutaneously. Methods Thirty pregnant women with gestational diabetes mellitus who had been in the department of outpatient of our hospital for delivery and hospitalization for more than 28 weeks from May 2018 to January 2019 were selected as the study subjects.Pregnant women were randomly divided into control group and study group according to parity, with 15 cases in each group.In the control group, traditional injection was used, while in the study group, a new Z-type injection method was adopted.The pain level, heart rate, and total incidence of adverse reactions (effusion,redness) were compared between the two groups. Results The pain in the study group was milder than that in the control group, the heart rate was slower than that in the control group, the differences were statistically significant (P<0.05).The total incidence of adverse reactions in the study group was lower than that in the control group, and the difference was statistically significant (P<0.05). Conclusion Subcutaneous injection of insulin to pregnant women by Ztype injection can alleviate the pain at the injection site, reduce the heart rate of pregnant women and the local adverse reaction rate, and improve the quality of clinical care.
