The Use of Ultrasound to Assess the Airway Anatomy Regarding Pharyngeal Seal and Its Protective Role Throw a Chemical Test for Three Supraglottic Devices (ProSeal LMA, I-gel, and I-gel Plus) (LMA)

2026年6月7日 更新者:Ain Shams University

Ultrasonographic Mapping of the Pharyngeal Seal and Its Protective Role for Three Supraglottic Devices (ProSeal LMA, I-gel, and I-gel Plus)

The goal of this clinical trial is to to evaluate the sealing quality of three second-generation SADs (ProSeal LMA, i-gel, and i-gel Plus) using ultrasonography to measure the cross-sectional area (CSA) of sealing, Anterior-Posterior (AP) Diameter and Transverse (TV) Diameter ,percentage of effective sealing , presence of sealing gap and correlate these anatomical findings with oropharyngeal leak pressure (OLP), while simultaneously testing relevant safety features of regurgitation risk through salivary pH measurement.

The findings from this investigation may contribute to improved device selection and enhanced patient safety during procedures requiring supraglottic airway management.
