AI-assisted ultrasound check for LMA placement in adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective observational study collects standardized ultrasound images after LMA insertion and compares AI-driven predictions to fiberoptic assessment, which serves as the reference standard. The fiberoptic grading defines optimal placement as Brimacombe grades 3–4 and suboptimal as grades 1–2. Three predictive approaches will be developed: (A) using clinical and ultrasound variables, (B) using post-placement ultrasound images with a transfer-learning image model, and (C) a multimodal combination of image features and tabular data. Model performance will be evaluated to identify optimal versus suboptimal LMA placement.
