Which airway opening technique should be used for a trauma client who may have a C-spine injury?

The jaw thrust maneuver is the most appropriate technique for opening the airway in a trauma client who may have a cervical spine injury. This technique is designed to minimize movement of the head and neck, which is crucial in cases where spinal injuries are suspected. By placing the fingers behind the angle of the jaw and pushing it upward while keeping the head in a neutral position, this maneuver effectively lifts the tongue away from the back of the throat to maintain an open airway without compromising the stability of the cervical spine.

In contrast, techniques such as the head tilt-chin lift are contraindicated for patients with possible C-spine injuries because they involve extension of the neck, which could exacerbate any potential damage. Endotracheal intubation, while medically necessary in some cases, is a more invasive procedure that requires proper training and is generally used when other airway methods fail. The insertion of an oropharyngeal airway is more appropriate for unconscious patients without suspected spinal injuries, as it also requires the ability to maintain a secured airway without risking further injury to the neck.
