My 14 week old daughter had an avsd open heart surgery repair which went well. now has a red rash around her scar. what could this reddening be?

Depends: It could be just a wound reaction or the process of wound healing, but it could also be an infection. Have the surgeon check it out because and infection could be very dangerous.

Cardiac Surgeon: Ask your cardiac surgeon. Without actually examining your daughter nobody can especulate a diagnosis.

I'm glad her repair: Went well. Do have one of her doctors check to make sure it's not a staph infection around the wound. It could be something simple, like a reaction to tape, but don't hesitate to get it checked out. If you start early intervention as " early prevention" when her sternotomy scar heals, you'll learn how to promote her development as you & she recover from the surgery & hospital stay.

Multiple Causes: This depends on when the surgery was done. Reddening could be a sign of infection. It could also be part of the normal healing, or simply an irritant rash. Please review this with your child's cardiologist.
