The Comparison of Three Treatment Methods in Repair of Deep Second Degree Burn Wounds

Objective To Comparison the effects of three treatment methods in deep second degree burn wound.Methods Twenty seven patients with deep second degree burn chosen and divided into the VSD group,SD-Ag group and eschar tangential excision group according to patients' intention, each group containing 9 cases.As to VSD group,pressure from20 to 60 kPa was applied to the wound for 7～10 days;in the SD-Ag group,SD-Ag topic agent was applied everyday;in the eschar tangential excision group,the wound eschar was excised tangentially and bio-dressing materials used to cover the wound in 24 hours after injury.Rehabilitation,regular follow-up and evaluation performed after treatment.Results Wound healing time,(18.64±3.25) d for VSD group,(22.35±3.45) d for SD-Ag group and(24.67±3.38)d for eschar tangential excision group.There was significant diference between SD-Ag,tangential excision groups and VSD group(all P0.05).Scar evaluation after one year follow-up was as follows;the cases with sign of -in the VSD group more than those significantly in the SD-Ag group and in the tangential excision group(P0.01 for both),and the cases with sign of+ or +++ were less than those significantly in the SD-Ag group and the tangential excicion group totally (P0.05 for both).Conclusion The VSD operation procedure is simple for effective drainage and autolysis debridement,rehabilitation at the same time would restore the appearance and function of the wound greatly with no obvious hypertrophic scars.
