Was wondering if anyone out there had an alternative to the VAC sponge for negative pressure wound care? We have had nothing but troouble with KCI and there money hungry administration in the last year and would like to tell them where to put there machines if it wasn't for the wound sponge. To date have found nothing that comes close to it. We have been experimenting with the Blue Sky machine as well as just putting the patient on wall suction with pretty fair results, but still need the sponge. Any suggestions?
