How can perfusion be assessed in a burn patient's extremities?

Assessing perfusion in a burn patient's extremities is critical to monitor for adequate blood flow and to detect any potential complications. Checking capillary refill time and assessing the presence of pulses are two key indicators of perfusion.

When evaluating capillary refill time, healthcare providers press on a nail bed or skin area until it blanches and then assess how quickly blood returns when the pressure is released. A quick return indicates good perfusion, while a delayed return may suggest compromised blood flow. Furthermore, checking for pulse presence ensures that blood is still being perfused through the arteries to the extremities. An absent pulse may indicate vascular compromise or the development of conditions such as compartment syndrome, which can occur after burns due to swelling or eschar formation.

While checking body temperature can provide some information about circulation, it is not a direct measure of perfusion status. Observing color changes in the skin can offer insights, but these changes can be subjective and are influenced by multiple factors; hence, they cannot provide the definitive information that capillary refill time and pulse assessment can. Applying pressure to the affected area may give insight into pain levels or tissue integrity, but it does not assess peripheral perfusion effectively.
