NCT07423741 | Recruiting

• 1 other identifier: ِAIP028-3
• Study Type: observational
• Target: 180
• Locations: 1 country
• Sites: 1

Brief Summary

Clinical and ultrasound indices of airway, in addition to laryngoscopic view will be assessed and compared among three groups of patients: non pregnant, pregnant with normal blood pressure, preeclampsia patients undergoing various surgeries under general anesthesia.

Conditions

Airway Assessment

Keywords

airway, ultrasound, preeclampsia

Outcome Measures

Primary Outcomes (1)

• Sperficial ultrasonographic airway assessemt

  By using superficial ultrasound probe, we measure in millimeters: anterior neck skin to hyoid bone distance, anterior neck skin to vocal cord distance (ANS-VC) ,distance from the epiglottis to the midpoint of the distance between the vocal cords (E-VC),the depth of pre-epiglottic space (Pre-E) and Pre-E/E-VC ratio). All parameters will be measured in millimeters in all groups by the same doctor, and the same ultrasound device.

  preoperative just before induction of anesthesia

Secondary Outcomes (3)

• Assessment of laryngoscopic view

  preoperative just before endotracheal intubation

• Tongue thickness

  Once just before induction of general anesthesia

• Hyoid bone visibility

  Preoperative just before induction of anesthesia
