Viability of Cadaver Skin Grafts Stored in Skin Bank at Two Different Temperatures (Correspondence) (Report)
Sir, In India, about 5 to 7 million burn cases occur every year and a great number of them can be salvaged if provided with a wound cover in time (1). Homografts limit infection, reduce protein and electrolyte loss and alleviate pain (1). The use of skin allografts is desirable in the treatment of patients with large wounds due to thermal injury. Hence the idea of preserving skin was conceived several years ago which led to development of skin banks. Skin Bank in L.T.M. Medical College & Hospital, Mumbai, was started in the year 2000 and is the first Skin Bank with the capability of harvesting cadaveric skin grafts in our country. Freezing of skin has been tried earlier and the necessary pre-requisites include treatment of skin with glycerol or dimethyl sulphoxide (DMSO) (2). Short-term storage in liquid nutrient medium is clinically desirable for certain length of time. Hence refrigeration using nutrient media becomes essential to maintain the viability (3).
