Background: Aortic cross-clamping is a high-stakes, technically challenging procedure typically reserved for highly-trained staff, which often excludes resident experience, leaving a crucial training gap for emergency situations. To address this, a mini-curriculum and 3-D hands-on simulation model for supra-celiac and infra-renal clamping were developed.
Methods: Participants, including medical students and up to fourth-year residents, completed pre- and post-surveys as well as hands-on practice. Metrics tracked included self-reported confidence and recorded clamping times.
Results: Twenty participants completed matched surveys. Significant improvements were seen in both efficiency and confidence. Average clamping times decreased by over one minute, dropping from 3 minutes, 4 seconds to 2 minutes, 2 seconds. Confidence scores, on a 1-10 scale, showed dramatic increases: supra-celiac clamping confidence rose by 4.55 points, infra-renal clamping confidence rose by 4.46 points, and overall assist confidence rose by 3.40 points. All participants reported increased confidence in independently performing the procedure. The model's hands-on simulation, tactile feedback, and intuitive use were rated highly for reinforcing anatomical knowledge and boosting skill acquisition.
Conclusion: We debuted an aortic cross clamp model demonstrating strong potential for enhancing surgical confidence, efficiency, and understanding in a low-stress environment. The model significantly reduced performance time, confirming its utility for high-stakes skill acquisition and curriculum integration.
