My hsband has a stage 4 with osteomyeltis in the ishium area ( sort of) top of thigh, crease of leg and bottom of butt cheek it's about 4 x 4 x 4.6 . The skin around the wound kept masserating due to massive amounts of drainage even with using cal. alginate and tegaderm, as well as mepilex foam dressing to collect the drainage. He thought the barrier cream would be a good thing to use only around the egde of the wound to try to keep the masseration to a minimum which it seems to have worked is this a good idea or not. I would appreciate any help.
