Successful resuscitation of a pregnant woman undergoing cardiac arrest and survival of the fetus require prompt, high-quality cardiopulmonary resuscitation. The objective of this observational study was to assess management of maternal cardiac arrest by anesthesia residents using high-fidelity simulation and compare subsequent performance following either didactic teaching or electronic learning (e-learning).
Twenty anesthesia residents were randomized to receive either didactic teaching (Didactic group, n = 10) or e-learning (Electronic group, n = 10) on maternal cardiac arrest. Baseline management skills were tested using high-fidelity simulation, with repeat simulation testing one month after their teaching intervention. The time from cardiac arrest to start of perimortem Cesarean delivery (PMCD) was measured, and the technical and nontechnical skills scores between the two teaching groups were compared.
The median [interquartile range] time to PMCD decreased after teaching, from 4.5 min [3.4 to 5.1 min] to 3.5 min [2.5 to 4.0 min] (P = 0.03), although the change within each group was not statistically significant (Didactic group 4.9 to 3.8 min, P = 0.2; Electronic group 3.9 to 2.5 min, P = 0.07; Didactic group vs Electronic group, P = 1.0). Even after teaching, only 65% of participants started PMCD within four minutes. Technical and nontechnical skills scores improved after teaching in both groups, and there were no differences between the groups.
There are gaps in the knowledge and implementation of resuscitation protocols and the recommended modifications for pregnancy among residents. Teaching can improve performance during management of maternal cardiac arrest. Electronic learning and didactic teaching offer similar benefits.
成功复苏心跳骤停的孕妇并使胎儿存活需要迅速、高质量的心肺复苏。本观察性研究的目的是使用高保真模拟评估麻醉住院医师对母体心脏骤停的处理,并比较随后接受教学或电子学习(e-learning)后的表现。
20 名麻醉住院医师随机分为接受教学(Didactic 组,n=10)或电子学习(Electronic 组,n=10)的组。使用高保真模拟对基线管理技能进行测试,并在教学干预一个月后重复模拟测试。测量从心脏骤停到围产儿剖宫产术(PMCD)开始的时间,并比较两组教学之间的技术和非技术技能评分。
教学后 PMCD 的中位[四分位数范围]时间从 4.5 分钟[3.4 到 5.1 分钟]缩短至 3.5 分钟[2.5 到 4.0 分钟](P=0.03),尽管每组内的变化无统计学意义(Didactic 组从 4.9 分钟到 3.8 分钟,P=0.2;Electronic 组从 3.9 分钟到 2.5 分钟,P=0.07;Didactic 组与 Electronic 组比较,P=1.0)。即使在教学之后,也只有 65%的参与者在四分钟内开始 PMCD。两组教学后技术和非技术技能评分均有所提高,且两组之间无差异。
住院医师对复苏方案和妊娠推荐修改的知识和实施存在差距。教学可以提高对母体心脏骤停的管理表现。电子学习和教学具有相似的益处。
