Introduction: Retrobulbar hemorrhage (RBH) occurs in only 0.45% of ocular trauma, but failure to provide timely lateral canthotomy and cantholysis (LCC) risks permanent visual deficits. With ocular trauma rates as high as 8.5-10% amongst modern combat injuries, and more than 2,000 severe eye injuries documented over a 10 year span, this concern increases.12-15 However, given infrequent RBH occurrence in the non-combat environment, emergency medicine residents trained in stateside settings may not receive adequate LCC exposure prior to military deployment. Simulators should be evaluated for procedural confidence compared to expensive and cumbersome traditional live tissue training (LTT) options. We seek to compare procedural confidence and usability of emergency medicine military residents performing LCC on a novel simulator to those using LTT. Methods: This study randomized 32 emergency physician and physician assistant residents to perform LCC on a simulator or LTT model. All received a standardized brief on RBH recognition and LCC, then completed an 11-question survey using a 100-mm visual numerical rating scale about their ability to correctly identify RBH and perform LCC. The survey was repeated after LCC completion. All volunteers additionally completed a 10-question survey utilizing a 5-point Likert scale on the usability of the model to which they were randomized. Results: No significant difference in reported confidence changes between groups was found; however, significant increases were found across all reported confidence measures between pre- and post-trainer use in the overall sample population. LCC simulator users reported significantly higher usability in 7 of 10 ratings. Conclusion: The lack of a statistically significant difference between groups in procedural confidence suggests artificial LCC simulators may offer an attractive alternative to logistically-complicated porcine models. Further research is needed to evaluate non-inferiority and procedural performance. [ABSTRACT FROM AUTHOR] |
