For a victim of a cervical spine injury, what first aid measures should be taken?

When handling a victim of a cervical spine injury, establishing an airway is crucial since any compromise can lead to severe complications. The jaw-thrust maneuver is particularly important in this context because it minimizes movement of the cervical spine, thereby reducing the risk of further injury. This technique involves displacing the jaw forward to open the airway without tilting the head back, which is essential in patients who may have a spinal injury.

Options involving logrolling, elevation of the feet, or the placement of a cervical collar do serve important roles in emergency care but are not the primary focus in the initial phase of managing a cervical spine injury. Logrolling might risk exacerbating the injury due to unnecessary movement, and elevating the feet could divert attention away from the more immediate need of ensuring the airway is patent. While a cervical collar is important for stabilization, it is not the immediate first aid measure to take in ensuring the airway is secured and may require advanced medical personnel to apply it properly. Therefore, prioritizing the airway with the jaw-thrust maneuver is the most appropriate first step in this scenario.
