What is the primary indication for using a KED in extrication?

The primary indication for using a KED (Kendrick Extrication Device) is indeed for seated patients involved in motor vehicle collisions (MVCs). The KED is designed specifically to stabilize and immobilize a patient's spine while allowing for safe extrication from a seated position, which is often required in the chaotic and potentially dangerous environment of a vehicle accident. This device securely supports the patient's head and neck while providing adequate spine support, which is crucial for minimizing further injury during the extraction process.

In cases of MVCs, patients may be trapped or pinned inside the vehicle, and the KED facilitates a controlled and safe removal while maintaining spinal alignment. This is especially important because improperly moving an injured patient could exacerbate spinal injuries or cause further harm. Therefore, its use is essential when dealing with the complexities of spinal immobilization in a seated scenario.
