What capillary refill time in neonates would indicate a suspicion of decreased intravascular volume?

• A. 2-3 seconds
• B. 4-5 seconds
• C. 6-7 seconds
• D. 1-2 seconds

Answer: (B)

Capillary refill time is a critical assessment tool used to evaluate peripheral perfusion and can help indicate a neonate's intravascular volume status. In neonates, a capillary refill time of 4-5 seconds is concerning and may suggest a reduced intravascular volume, which can occur in situations like dehydration, shock, or significant fluid loss. When the capillary refill exceeds 2 seconds, it suggests that peripheral circulation is compromised, indicating that the body is prioritizing blood flow to vital organs. A refill time within the range of 4-5 seconds can be a sign that there is inadequate blood volume returning to the heart, which may lead to or be indicative of a more serious underlying issue. A significantly prolonged capillary refill time, especially if reaching 6-7 seconds or beyond, highlights a pressing need for medical intervention and evaluation. In contrast, a refill time of 2-3 seconds could fall within an acceptable range in some situations, and a 1-2 second refill time generally indicates adequate perfusion and normal intravascular volume. Thus, the suspicion of decreased intravascular volume is particularly associated with the 4-5 seconds window.
