Final answer:
A patient with a possible head or spine injury while sitting will likely need a Kendrick Extrication Device. This device is used to immobilize the patient's spine during extraction to prevent further injury.
Step-by-step explanation:
A patient who is in a sitting position and has a possible head or spine injury will probably need a Kendrick Extrication Device (KED). The KED is a device specifically designed for the immobilization of patients with suspected spinal injuries during extraction from an accident scene, particularly when they are found in a seated position, such as in a vehicle. Its use minimizes movement of the spine, reducing the risk of further injury.
When using a KED, rescuers can properly secure the patient's torso, head, and neck, which provides the necessary spinal immobilization. They then can move the patient to a spine board or other transport device with less risk of exacerbating the injury. This contrasts with options like the log roll or lateral transfer, which are not typically used for patients in sitting positions or when a precise spinal immobilization is required. A scoop stretcher, while useful in some scenarios, does not offer the spinal support needed for a patient in a seated position with a potential spinal injury.
