Use of a beef tongue model and instructional video for teaching residents fourth-degree laceration repair

摘要

Introduction and hypothesis: This study seeks to compare the utility of the beef tongue model versus an instructional video in teaching obstetric and gynecology residents how to repair a fourth-degree laceration. Methods: Twenty-seven residents were randomized to participate in a workshop with a beef tongue model or assigned to watch an instructional video on repair of fourth-degree lacerations and read a chapter on the repair. All subjects were tested with a pre- and postintervention written test. These scores were compared with paired t test at 0.05 significance level. Results: Residents with no prior experience in fourth-degree laceration repairs showed an improvement in knowledge (49.5% versus 64.1%, p < 0.001) on written exams about the repairs. Conclusions: An instructional video or beef tongue model and textbook chapter on fourth-degree laceration repair can improve skills in repair of a fourth-degree laceration among residents with no experience in these repairs.
