Clinical study of tangential excision on burn wounds within 48 hours in patients with deep partial thickness burn

Objective:To study the effects of tangential excision on burn wounds within 48 hours in patients with deep partial thickness burn.Methods:Tangential excision on burn wounds within 48 hours was carried out on 79 patients with 15%~40% burn injury, while another 56 similar patients were taken operation 5～7 days post injury as control. The wound healing time and the patients complication were observed,and the histopathological observation was made.Results:We found the wound healing time in study group (22.32±4.57 days) was significantly less compared with that (28.71±6.39days) in control group(P 0.05). The histopathological observation of the wounds in study group revealed that the extent of tissue damage became limited compared with the control group.Conclusion:The study shows that tangential excision within 48 hours in deep partial thickness burn patients suffering less 40% burn injury is safe and effective to the wound healing.
