Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults over 18 years old undergoing elective surgeries that require general anesthesia and endotracheal intubation.

Probably not a fit

Patients undergoing obstetric surgeries, those who are pregnant, or individuals with prior neck surgeries or cervical radiation history may not benefit from this study.

What this trial studies

This observational study aims to investigate the effectiveness of point of care ultrasound (POCUS) in evaluating difficult airways during elective surgeries requiring general anesthesia and endotracheal intubation. It focuses on measuring specific ultrasound parameters of the anterior neck to predict challenges in bag and mask ventilation and laryngoscopy. The study is being conducted at the University Hospital of Ioannina and seeks to enhance the understanding of ultrasound as a tool in airway management. By exploring this new application, the research aims to improve patient safety and outcomes in anesthesia.

Why it matters

Potential benefit: If successful, this study could lead to improved prediction and management of difficult airways, enhancing patient safety during anesthesia.

How similar studies have gone: While there are few studies on the use of POCUS for airway evaluation, this approach is relatively novel and has not been extensively tested.
