We like to refer to Dr. William's lecture as Wound Care 101, because it offers a basic foundation on which to build a cadre of wound care knowledge. The phases, stages, etiologies and classifications are outlined, giving the practitioner a method of compartmentalizing each particular wound. Creating the optimum microenvironment is the key to success in treating wounds. Dr. Williams categorizes the available wound products and discusses the method by which they restore a suitable environment for healing. Alginates and collagenates are excellent for wounds with heavy exudates, but when do we use foams and hydrogels? Are platelet derived growth factors a magic bullet? Should enzymatic debriding agents be discontinued once the necrosis has been removed? Biosynthetic skin substitutes are typically derived from fetal foreskin. Will these products increase in size if they are gently manipulated? Dr. Williams addresses these and other issues in classification and differential diagnosis of wounds.
