Sorry I took a while to respond back about the wound vac question. My incision got infected when an overly eager resident let feces get into my incision and just dabbed the superficial feces away with gauze. I asked her to flush out the incision and she said no it will be okay. Needless to say after many bad calls on her part I no longer even allowed her to enter my room. The wound vac helps to suction out the infection and it also helps to speed up healing by up to 60%. It stinks having to carry around a battery operated vac caister thoough. If you want more info you can look up KCI wound vacs.
