The modified jaw thrust maneuver outperformed both BURP and conventional one-handed jaw thrust maneuvers, providing superior laryngeal view and time to intubation.
The Clarus Video System is a malleable fiberoptic stylet with an attached video camera. The endotracheal tube is loaded onto the stylet and guided through the vocal cords, without need for a laryngoscope. To determine the best maneuver to facilitate glottic view and intubation with the Clarus Video System, researchers compared backward, upward, rightward pressure (BURP), modified (two-handed) jaw thrust, and conventional jaw thrust (single-handed chin lift by the operator). BURP and two-handed jaw thrust were applied by a trained assistant blinded to glottic view. All three maneuvers were performed on each of 209 adult patients (age range, 18 to 70 years) with American Society of Anesthesiologists status 1–3. Patients with history of, or an…
