What role does capillary refill time play in trauma assessment?

Capillary refill time is a valuable assessment tool that provides insight into peripheral circulation. When assessing capillary refill, the healthcare provider observes the time it takes for color to return to an extremity after applying pressure, typically to a nail bed. In the context of trauma assessments, an elongated capillary refill time, generally exceeding two seconds, may suggest inadequate perfusion and potentially indicate shock or compromised circulation. By evaluating capillary refill time, clinicians can gather important information about a patient’s hemodynamic status and guide further interventions to support circulation and address any underlying issues.
