Point-of-care ultrasound of the upper airway in difficult airway management: a systematic review and meta-analysis
This systematic review and meta-analysis examined the use of point-of-care ultrasound (POCUS) for predicting and managing difficult airways. It found that several ultrasound measurements of the upper airway (tongue, epiglottis, vocal cords, hyoid bone) can be helpful in predicting difficult facemask ventilation, laryngoscopy, and tracheal intubation, and can improve first-pass success rates for surgical airways like cricothyrotomy and tracheostomy.
