Trial of Drain Antisepsis After Tissue Expander Breast Reconstruction

10 ml of 0.125% sodium hypochlorite (Dakin's solution) irrigation to the drainage bulb two times a day

Apply one chlorhexidine disk to the intervention drain site(s) and change every three days

Standard drain care will be performed twice a day or three times if bulb is full and needs to be emptied. Standard drain care consists of stripping the tubing, emptying the drainage bulb, recording the volume of fluid, and cleaning the drain site with a cotton swab dipped in rubbing alcohol. The drain exit will be covered with a dry sterile gauze dressing and changed after each episode of drain care.

A chlorhexidine gluconate disk (BioPatch) covered by an occlusive adhesive dressing (Tegaderm) will be applied to the intervention drain sites and changed every three days.
