Pudendal nerve block is an important alternative to neuraxial anesthesia, yet studies demonstrate that 3% to 50% of pudendal nerve blocks are ineffective. Lack of clinician training is the most common cause, and there are no simulation models currently described.
To develop and test a novel, low-cost, low-fidelity simulation model for training residents in the placement of a pudendal nerve block.
A pudendal nerve block model was developed using commonly found supplies, with a cost of $20.57. First-year to fourth-year obstetrics and gynecology (OB/GYN) and family medicine (FM) residents were invited to 1 of 4 pudendal nerve block 1-hour simulation sessions from December 2019 to March 2021 during their required teaching sessions. Expert faculty led a discussion of pudendal nerve blocks, then participants practiced with the described model. A survey about the model was created by the authors and administrated prior to and immediately after the session. Pre- and post-surveys were analyzed by Wilcoxon signed rank tests, and Bonferroni correction was performed.
Thirty-four out of a total of 36 eligible residents participated (94%). Residents showed improvement in knowledge (median pre-simulation score 43.99 compared with 70.06 post-simulation, <.00625) and self-assessed confidence (median pre-simulation score 1.7 compared with 3.2 post-simulation, <.00625) of a pudendal block placement after simulation training.
This new, low-cost, reusable, low-fidelity simulation model for pudendal nerve block placement improved knowledge and confidence in OB/GYN and FM residents after 1 hour of simulation training.
阴部神经阻滞是椎管内麻醉的重要替代方法，但研究表明，3%至 50%的阴部神经阻滞无效。缺乏临床医生的培训是最常见的原因，目前尚无描述的模拟模型。
开发和测试一种新的、低成本、低保真度的模拟模型，用于培训住院医师进行阴部神经阻滞。
使用常见的用品开发了一种阴部神经阻滞模型，成本为 20.57 美元。2019 年 12 月至 2021 年 3 月，在规定的教学时间内，邀请第一年至第四年的妇产科和家庭医学（FM）住院医师参加 4 个阴部神经阻滞 1 小时模拟课程中的 1 个。专家教师就阴部神经阻滞进行了讨论，然后参与者使用描述的模型进行了练习。作者创建了一个关于该模型的调查，并在课程之前和之后立即进行了管理。使用 Wilcoxon 符号秩检验对预调查和后调查进行分析，并进行了 Bonferroni 校正。
共有 36 名符合条件的住院医师中的 34 名（94%）参加了研究。在模拟培训后，住院医师在阴部神经阻滞的知识（模拟前评分中位数为 43.99，模拟后为 70.06，<.00625）和自我评估的信心（模拟前评分中位数为 1.7，模拟后为 3.2，<.00625）方面均有改善。
这种新的、低成本、可重复使用、低保真度的阴部神经阻滞模型可提高妇产科和 FM 住院医师在 1 小时模拟培训后的知识和信心。
