What does a decreased capillary refill time indicate during a neurovascular assessment?

A decreased capillary refill time indicates poor blood circulation. Capillary refill time is a quick test used to assess peripheral blood flow by measuring how quickly blood returns to the capillaries after a brief period of pressure. A normal capillary refill time is generally considered to be less than two seconds. When this time is prolonged, it suggests inadequate perfusion and oxygen delivery to the tissues, which can indicate that blood circulation is compromised.

In a neurovascular assessment, such findings can be critical as they may point to conditions such as vascular insufficiency, compartment syndrome, or other circulatory issues. Monitoring capillary refill is particularly important in orthopedic nursing, especially in patients with injuries or surgeries that might affect limb perfusion. Thus, a prolonged capillary refill time serves as a vital sign of poor blood circulation that requires further investigation and possibly intervention.
