目的 基于微信小程序开发胎心监护学习平台，验证其在本科护理专业学生中的应用效果。方法 开发适配于微信小程序的移动胎心监护学习平台，用户端包括胎心监护基础知识、胎心监护图谱库、名师讲堂、互动问答、闯关排位模块。选取四川省成都市某综合大学护理学院2019级护理学助产方向的23名本科生为研究对象。收集学生使用平台学习时长、频率；比较分析学生在使用平台前后胎心监护相关知识测试；调查其对平台的满意度。结果 21名学生使用胎心监护教学平台1~3次/周，18名学生使用胎心监护教学平台不足30 min/周。使用平台进行辅助学习后，学生的胎心监护相关知识测试成绩高于使用前（P<0.05），学生对平台使用满意度高。结论 该平台的使用能一定程度地辅助提高胎心监护教学效果，丰富教学方法，补充教学内容。

Objective To develop a fetal heart monitoring learning platform based on WeChat mini program and verify its application effect among undergraduate nursing students.Methods A mobile fetal heart monitoring learning platform adapted to WeChat applet was developed，with a user port consisting of five modules：basic knowledge module of fetal heart monitoring，fetal heart monitoring map library module，renowned teachers lecture module，interactive Q&A module，game challenge module. Twenty-three undergraduate students（hereinafter referred to as “students”） from the nursing school of a comprehensive university in Chengdu City，Sichuan Province，in the class of 2019 in the direction of nursing midwifery，were selected as the study subjects. The research team collected the duration and frequency of students’ use of the platform for learning，and compared and analyzed students’ knowledge tests related to fetal heart monitoring before and after using the platform，and investigated their satisfaction with the platform.Results Twenty-one students used the fetal heart monitoring teaching platform 1-3 times per week，and 18 students used the fetal heart monitoring teaching platform for less than 30 minutes per week. The test scores of students on fetal monitoring-related knowledge after using the platform for assisted learning were higher than those before using the platform（P<0.05），and students showed high satisfaction with the platform.Conclusion The use of the platform can improve the teaching effect of fetal monitoring to a certain extent，enrich the teaching methods of fetal monitoring，and supplement the teaching content of fetal monitoring.
