Oberservation of the protective effect on nanometer silver dressing in burn wound

Objective To investigate the protective effect of wound in burn part of wound on nanometer silver dressing.Methods Selected 48 fleet Ⅱ degree and deep Ⅱ degree burn patients of burn deepness equality opposite nonarthrosis place.Two burn wound of deepness equality consistent of the each case were randomly divided in two comparison area.The treatment groups adopted nanometer silver dressing apply.The comparison groups adopted 1%SD-Ag cool frost apply on vaseline gauze.Put up wound secretion germiculture and judged with two groups wound at 3 postburn day(PBD3),PBD5,PBD9 and PBD14.Observed and noted the wound heal instance and speed.Observed the medicament badness responses.Results The wound germ tested rate compare: the masculine rate fleet Ⅱ degree 3.84% and deep Ⅱ degree 9.09% in the treatment groups.The masculine rate fleet Ⅱ degree(11.53)% and deep Ⅱ degree 18.18% in the comparison groups.The wound heal time compare: the treatment groups average shorter two-three days than the comparison groups in the fleet Ⅱ degree.The treatment groups average shorter four-five days than the comparison groups in the deep Ⅱ degree,P(0.05). The treatment groups wound heal speed faster than the comparison groups in the postday 7 of two groups wound,P0.01.Two groups have not allergy responses. Conclusion Nanometer silver dressing have notable contend with germ and promote curative effect of the wound heal.It is clinical burn external use dressing of the litter toxicity and side effect and apply convenience.
