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)

Condition(s) studied

Investigational drug(s) / intervention(s)

evaluate the sealing quality (ProSeal LMA)using ultrasonography and a biochemical non invasive test to evaluate regurgitation: This multimodal approach, combining ultrasound assessment of sealing quality with biochemical monitoring of regurgitation, may provide valuable insights into the comparative effectiveness of different SAD designs and ensure patient safety.

evaluate the sealing quality of SGA device ( i-gel)using ultrasonography and a biochemical test for assessment of regurgitation: This multimodal approach, combining ultrasound assessment of sealing quality with biochemical monitoring of regurgitation, may provide valuable insights into the comparative effectiveness of different SAD designs and ensure patient safety.

evaluate the sealing quality of SGA device ( i-gel plus )using ultrasonography and a biochemical test for assessment of regurgitation: This multimodal approach, combining ultrasound assessment of sealing quality with biochemical monitoring of regurgitation, may provide valuable insights into the comparative effectiveness of different SAD designs and ensure patient safety.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Ultrasound mapping of sealing efficacy with correlation to OLP — The primary outcome will be assessed throw the operation time from 2 hours to 4 hours time frame to obtain this outcome.
