Abstract
Background: 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. Objective: To develop and test a novel, low-cost, low-fidelity simulation model for training residents in the placement of a pudendal nerve block. Methods: 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. Results: 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, P<.00625) and self-assessed confidence (median pre-simulation score 1.7 compared with 3.2 post-simulation, P<.00625) of a pudendal block placement after simulation training. Conclusions: 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.
