Ultrasound Predictors of Difficult Airway in Adults

Turkey (Türkiye)400 participantsStarted 2023-10-01

Plain-language summary

Difficult airway management is a major cause of perioperative complications. Standard bedside airway assessment tests may have limited ability to predict difficult intubation and difficult mask ventilation. This prospective observational study aims to evaluate whether preoperative ultrasound measurements of airway structures (such as skin-to-epiglottis distance, tongue thickness, and pre-epiglottic space) can predict difficult intubation and difficult mask ventilation in adult patients undergoing surgery under general anesthesia.
