Abstract
Abstract Treatment of skin wounds with starch hydrolysate composition can be improved by irrigating the wound with a buffered salt solution having a pH in the range of approximately 6-7.8 prior to application of the starch hydrolysate composition. Additionally, the treatment can include further irrigation with amino acid solution. A preferred starch hydrolysate composition is compounded to include alphaketoglutaric acid or a salt thereof.
