This does not sound like any VAC from KCI...if your patient has two Stage 4 wounds and sounds like excessive drainage you may want to consider them to be evaluated in the hospital first. They need to have wound status evaluated, make sure no infection, then plan of care would address needs of patient. When you have excess drainage you have to look at how to control it and wick it away from intact skin....your vac system does NOT sound adequate to start with. First take care of infection if there is one, which will decrease the amount of drainage. then get a real vac system from KCI,,,if this is not an option then stop that suction set - up and use skin barrier wipes around wounds to intact skin,,,,,then fill the dead space (pack the wound) with a dressing that holds more than its weight in exudate (drainage)...such as foam dressings or aglinates,,,,if there is any tenneling or undermining you will need to pack these areas with kerlex to help wick exudate out of those tunnels....ABD's on top is cheap alternative....change 3-4 times a day....if you are close to Wichita area there are several good wound care docs...hope this at least gets you some relief,,,,
