In trauma patients, when is it appropriate to perform a head-tilt/chin-lift?

The correct answer is that it is appropriate to perform a head-tilt/chin-lift in trauma patients when there is no other way to open the airway. This technique is primarily used to clear an obstructed airway, particularly if the patient is unresponsive or has inadequate spontaneous breathing.

In trauma scenarios, airway management is critical, and maintaining spinal stabilization is key, especially in patients with suspected cervical spine injuries. Therefore, if initial methods, such as jaw thrust maneuvers (which are preferred in suspected spinal injuries because they do not compromise spinal alignment), prove ineffective or if the airway cannot be opened by other means, then a head-tilt/chin-lift may be utilized as a last resort to provide ventilation.

Using the head-tilt/chin-lift can allow the rescuer to assess the airway more effectively and potentially provide necessary interventions. However, it is vital to be mindful of the potential risks involved, particularly concerning any underlying spinal injuries. Thus, the appropriate context for this action is when all other options to secure the airway have been exhausted.
