When should you check pulse, motor, and sensory (PMS) in patients?

Checking pulse, motor, and sensory (PMS) functions both before and after splinting is crucial for several reasons. This procedure ensures that the extremities are functional and that there are no significant changes in the patient’s condition as a result of the immobilization process.

Assessing PMS before splinting provides a baseline that helps identify any existing deficits in circulation, movement, or sensation. After splinting, it is equally important to re-evaluate these functions to ensure that the splint has not compromised blood flow or nerve function. This practice is particularly vital when dealing with potential fractures or spinal injuries, as improper immobilization can exacerbate an injury or lead to further complications.

By consistently checking PMS at these two points, emergency responders can monitor the patient's status and ensure timely interventions if there are any adverse changes in limb function. This approach enhances overall patient safety and care during pre-hospital treatment and transport.
