Had a BA and BL, two weeks post op, went back in for hematoma drain. No antibiotics given. 1 week after that, had drainage, admitted to hospital for IV (vanco). Culture taken and results came back with E. coli?! Have always had stitches and bandages, could this have happened during surgery? Have switched antibiotics to treat E. coli. Concerned about implant infection. Redness is gone and I feel better, just concerned and not sure what to look for and how this happened!
