目的 探讨复杂性会阴裂伤仿生模具(以下简称仿生模具)在新助产士培训中的应用效果。方法 采用试验对照方法。于2017年8月至2019年8月,采用仿生模具,在同济大学附属第一妇婴保健院对新助产士开展4期复杂性会阴裂伤修复的模拟培训,共培训70人。在每期培训的第2周和第8周,采用自行设计的会阴裂伤修复技能评价表评价培训前后新助产士对会阴裂伤修复技能的掌握情况,采用自行命题于培训前后对新助产士进行理论考核;并在实训结束后采用问卷调查表,由新助产士对仿生模具模拟训练效果进行评价。结果 培训前后助产士缝合完成时间分别为(28.16±6.57)分钟比(23.54±4.54)分钟,其差异具有统计学意义(P<0.01);解剖层次清晰度技能评分分别为(5.75±2.44)分比(7.83±1.24)分,其差异具有统计学意义(P<0.01);综合理论考核成绩分别为(61.45±4.76)分比(83.60±4.31)分,其差异具有统计学意义(P<0.05); 70名新助产士对仿生模具模拟训练的18个条目均给予满意的评价。结论 采用仿生模具进行修复模拟培训能够提高新助产士快速掌握复杂会阴裂伤的识别能力、修复术操作技能,有效提高了教学效果。

Objective To explore the application effect of bionic mold (hereinafter referred to as bionic mold) for complicated perineum laceration in midwife training. Methods Comparison method was used. From August 2017 to August 2019, the new midwives from the East Hospital, the West Hospital and the South Hospital ofFirst Maternity and Infant Hospital, Tongji University School of Medicine carried out four simulated training sessions of complex perineum laceration, each of which lasted for 2 weeks and 8 weeks, with a total of 70 trainees. In the second and eighth week of each training, the self-designed evaluation table of perineal laceration repair skills was used to evaluate the new midwives' mastery of perineal laceration repair skills before and after the training. After the training, the new midwives were assessed with self-made questions before and after the training, and the effect of bionic mold simulation training was evaluated by the new midwives through questionnaire after the training. Results Before and after training, the suture completion time of midwives was (28.16±6.57) min vs (23.54±4.54) min, the difference was statistically significant (P<0.01); the anatomical level clarity skill score was (5.75±2.44) points vs (7.83±1.24) points, the difference was statistically significant (P<0.01); the comprehensive theory examination scores were (61.45±4.76) The score ratio was (83.60±4.31), the difference was statistically significant (P<0.05); 70 new midwives gave satisfactory evaluation on 18 items of bionic mold simulation training. Conclusions Using the bionic mold of complex perineum tear in simulation training can quickly grasp the diagnosis and identification of complex perineum tear wound, and consummate the operation skills of repair. On the basis of conforming to medical ethics, the clinical teaching quality for training new midwife is significantly improved, which is worthy of clinical promotion and application.
