This prospective randomized controlled study assessed whether supraglottic jet oxygenation and ventilation (SJOV) improves skill acquisition, reduces hypoxemia, and enhances trainee performance during simulated difficult airway training. Twenty third-year residents performed 25 fiberoptic intubations each on simulated difficult airways, totaling 500 intubations, with SJOV compared against facemask ventilation.

Simulation-based training is essential for anesthesia residents to learn fiberoptic intubation safely. This study evaluated the effect of Supraglottic jet oxygenation and ventilation (SJOV) on skill acquisition, hypoxemia, and trainee performance during simulated difficult airway training.  \nMaterial/Methods: This prospective randomized study included 20 third-year anesthesia residents without prior fiberoptic intubation experience. Each performed 25 fiberoptic intubations (total=500) on patients wearing a cervical collar to simulate a difficult airway. Residents were randomized to SJOV with 15 pounds per square inch (PSI), 15 breaths/min, fraction of inspired oxygen (FiO2) 100%, or facemask ventilation. Primary outcomes were the number of cases to achieve procedural competency by cumulative sum (CUSUM) analysis, incidence of hypoxemia [peripheral oxygen saturation (SpO2) \u003C90%, and competency scores assessed by the Direct Observation of Procedural Skills (DOPS) and Mini-Clinical Evaluation Exercise (Mini-CEX). Secondary outcomes included intubation time and trainee-reported confidence and satisfaction.  \nResults: Residents in the SJOV group achieved competency after a median of 11 cases, compared with 18 cases in the facemask ventilation group. Hypoxemia occurred in 0% of the SJOV group versus 10% in the facemask ventilation group (P\u003C0.001). DOPS scores were higher in the SJOV group (P=0.01), while Mini-CEX scores were similar (P=0.64). Residents using SJOV reported greater confidence (P=0.003), engagement (P=0.008), and satisfaction (P=0.012).  \nConclusions: SJOV accelerates skill acquisition, prevents hypoxemia, and improves performance during simulated difficult airway training. Integrating SJOV into residency programs may enhance the safety and efficacy of fiberoptic intubation training.  \nKeywords: Airway Management • Anesthesia • Oxygen Consumption • Randomized Controlled Trial  \nFull-text PDF: [https://www.medscimonit.com/abstract/index/idArt/950813](https://www.medscimonit.com/abstract/index/idArt/950813)  \n3326  3  2  22  \nPublisher’s note: All claims expressed in this article are solely those of the authors and do not necessarily represent those of their affiliated organizations, or those of the publisher, the editors and the reviewers.
