Objective To study the effect of the compatibility on treating Ⅱ toⅢphase pressure sore of senior citizen by auricularia in-depth fermentation extracts and the dimethyl acrylyl hydropathic compress.Methods A total of 60 patients with Ⅱto Ⅲ phase pressure sore were divided randomly into the expedmental group and the control group with 30 cases in each group.The experimental group(30 cases.50 pressure sores)were treated with the auricularia in--depth fermentation extracts and the dimethyl acrylyl hydropathic compress.The control group(30 case8,46 pressure sores)were treated with conventional methods of dressing change,0.5% iodine to disinfect the wound surface.then bounded it up with the aseptic vaseline yarn and the sursical dressing.The curative effect Was compared by observing the effect indicators.Results The response rate of the experimental group was 100.0%.with an average healing time of 10.33 d.For the control group.the response rate was 78.3%,the average healing time Was 24.27 d.There Was significant difference on efficiency and the average healing time between the two groups,P<0.01.Conclusions Auricularia in-depth fermentation extracts and the dimethyl acrylyl hydropathic compress to treat the senior citizen Ⅱ toⅢphase pressure gore with a view to easy.safe and economical characteris tic.has a significant effect on the new agricultural co-medical health care and community groups.
