Introduction: "See one, do one, teach one" has represented the model for surgical education for over a century, however recent changes in education have reduced autonomy in training. The goal of this study was to assess the impact of autonomy on learning a procedural skill.
Methods: Senior medical students were randomized and trained to performance a vascular anastomosis utilizing progressive autonomy vs. constant supervision. Performance was tested using videotaped technical grading and anastomotic pressure testing.
Results: Mean baseline performance times and technical ratings were similar in both groups. Final completion times was faster in the autonomy group, 14:03min vs. 19:09min (p = 0.02). Final technical ratings were similar, 40.0 vs. 39.2points (max = 50), for each group and both demonstrated similar improvement in leak test against a standardized sample.
Conclusion: Teaching a procedure, as a final step in graded autonomy, results in superior performance in timing while maintaining equal technical performance compared to trainees with less autonomy.

Purpose: The aim of the study was to evaluate operative time and postoperative complications of 4 post-training specialized surgeons.
Methods: This was a pilot retrospective chart review to determine the learning curve of a Shouldice primary inguinal hernia repair (Shouldice Repair) of 4 post-training specialized surgeons, at the Shouldice Hospital. The first 300 Shouldice Repairs (early learning block) were compared to their 900-1,000 repairs as the primary operating surgeon (late learning block).

Background: Invasive systems are commonly used for monitoring intracranial pressure (ICP) in traumatic brain injury (TBI) and are considered the gold standard. The availability of invasive ICP monitoring is heterogeneous, and in low- and middle-income settings, these systems are not routinely employed due to high cost or limited accessibility. The aim of this consensus was to develop recommendations to guide monitoring and ICP-driven therapies in TBI using non-invasive ICP (nICP) systems.
