目的：探讨改良抗凝剂脐周皮下注射方法的教学方法。方法：将32名护生分为两组,对照组16名护生先独立进行操作,出科时进行理论+实践考核。实验组护生了解微信版皮下注射PPT课件以及操作视频、药品说明书、皮下注射专家共识；老师床头解读示范操作流程,护生模拟练习。理论+实践考核合格后为患者独立注射。比较两组护生理论及实践考核成绩,两组患者皮下注射不良反应发生率。结果：实验组护生皮下注射知识考核分数、皮下注射操作考核分数明显高于对照组,差异有统计学意义(P＜0.01)实验组患者皮下注射不良反应发生率明显低于对照组,差异有统计学意义(P＜0.01)。结论：护生独立皮下注射前需要进行规范培训,正确掌握皮下注射要点是降低不良反应的关键。

Objective: To explore the teaching method of improving the way of subcutaneous injection of anticoagulant around the umbilical cord. Method: Divide 32 nursing students into two groups. The 16 nursing students perform the operation independently in the control group ,then all of the students do theory test and practice assessment when they leave the department. The other 16 nursing students in the experimental group learn hypodermic injection from PPT, as well as operation videos, drug instructions, and expert consensus on hypodermic injections through wechat app. After that teacher will gave a lesson about the operation process, and nursing students simulated exercises. When they pass all the test, students could inject to patients independently. Comparing the results of the tests in two groups of nursing students, and contracting the incidence of adverse reactions of the two groups of patients. Results: The test scores of the experimental group were significantly higher than those of the control group. The difference was statistically significant (P＜0.01). The incidence of subcutaneous injection adverse reactions in the experimental group was significantly lower than that of the control group. The difference was statistically significant (P＜0.01). Conclusion: Standardized training and correct theoretical knowledge before independent subcutaneous injection is the key to reducing adverse reactions.
