The main idea is to prevent any movement of the cervical spine while preparing for transport, with airway protection as needed. Start by in-line, manual stabilization of the head and neck in a neutral position to stop movement. While maintaining that stabilization, assess and support the airway and breathing, providing ventilation if required. After stabilization and airway management, apply a rigid cervical collar to lock the neck in place and then secure the patient to a long spine board to keep the entire spine immobilized during transport. Finally, proceed with rapid transport to a facility equipped to manage spinal injuries. This approach minimizes the risk of worsening a cervical spine injury during movement and ensures timely definitive care. Choosing options that involve only monitoring without immobilization, removing protective devices, or delaying immobilization for full on-scene treatment could increase the chance of secondary injury.
