Apparatus and method for applying more uniform pressure to an area of skin that is undergoing a skin graft. Pressure pad comprises a soft, pliable, transparent plastic envelope fillable with a viscous, transparent liquid to provide even distribution of pressure while permitting visual inspection of, and transmission of radiation to bathe the skin graft area, without removal of the pressure pad. Pad is removably securable to the area adjacent the graft by a variety of securing means. In one embodiment the graft area contact surface of the pad is specially adapted to permit air to contact the graft tissue. Pad is sterilizable, and the envelope is of a nature that drying tissue and serous fluid will not adhere to it. Pad preferably has a port permitting precise control of the amount of liquid fill (preferably silicone) in the bag, introduced or withdrawn by means of a syringe. In turn, this permits precise control of the pressure applied to the graft tissue. Pad structure is adapted to be highly conformable to irregular surface contours insuring full contact and uniform hydrostatic pressure on graft tissue.
