Capillary refill time is a quick bedside test used to assess perfusion in which population?

• A. Adults
• B. Infants and children
• C. Elderly
• D. Athletes

Answer: (B)

Capillary refill time is a quick, noninvasive way to gauge peripheral perfusion by pressing on a small area (like a fingernail bed) until it blanches and then timing how long color takes to return. This check is especially useful in infants and children because their microcirculation can reflect changes in circulatory status rapidly, such as dehydration or early shock, and it can be done quickly at the bedside without equipment. In pediatric care, a normal refill is typically within about two seconds; a prolonged refill suggests reduced perfusion and possible fluid loss or shock. In adults, the test is less reliable because factors like cooler environments, skin thickness, vascular disease, and medications can alter refill time and confound interpretation. The same confounding issues are more pronounced in older adults and in people with chronic conditions, so the test is not as dependable in those populations.
