I just wanted to say hello and introduce myself. I am a caregiver and have been for 2 years now. I am 41 years old and live in Mississippi. I have been taking care of a paraplegic and he has just had a flap done on left ishium. Before surgery, he had a wound vac. He has it back in because of a tear in his suitures. I am having a heck of a time keeping that vac sealed because of the drainage. Anyone here have any advice at all?
