Capillary refill time greater than 10 seconds in the hand with the graft placement most likely indicates which condition?

• A. Graft infection.
• B. Circulatory compromise or steal syndrome.
• C. Dehydration.
• D. Normal perfusion.

Answer: (B)

Capillary refill time measures how quickly blood returns to the distal tissues after pressing on the nail bed, reflecting distal perfusion. A refill time greater than 10 seconds in the hand with the graft indicates significant ischemia of that hand, pointing to circulatory compromise related to the graft—often called steal syndrome—where blood is diverted away from the distal limb into the graft. This is an urgent finding because prolonged ischemia can cause tissue damage. It’s not dehydration, which wouldn’t produce a localized, markedly delayed refill in the grafted hand; nor infection, which would present with local signs of inflammation (redness, warmth, drainage) and possibly fever; nor normal perfusion, which would have a quick refill (typically under a few seconds).
