Treatment of deep burn with escharectomy and skin grafting combined with negative pressure wound / 中国基层医药

ABSTRACT

Objective:To explore the efficacy and safety of escharectomy and skin grafting combined with negative pressure wound treatment in the treatment of patients with deep burn.Methods:A total of 208 deep burn patients who were treated in Haining People's Hospital from May 2018 to May 2019 were selected in the research.They were randomly divided into observation group and control group according to the random digital table method, with 104 cases in each group.The observation group was treated with escharectomy and skin grafting combined with negative pressure wound treatment.The control group was treated with escharectomy and skin grafting combined with traditional pressure bandaging.The general treatment, wound healing rate, changes of serum inflammatory factors before treatment and after treatment for 7 days, and complications of the two groups were compared.Results:The total excellent and good healing rate of the observation group (92.31%) was higher than that of the control group (79.81%) (χ 2=6.772, P<0.05). The granulation growth time [(8.23±2.16)d], wound healing time [(17.64±2.58)d], postoperative pain score[(3.16±1.24)points] and hospitalization time [(22.61±2.47)d] in the observation group were lower than those in the control group [(12.15±2.33)d, (20.25±3.16)d, (5.33±1.27)points and (26.13±2.55)d] ( t=12.582, 6.525, 12.468, 10.111, all P<0.05). At 7 days after treatment, the levels of CRP[(21.12±2.48) ng/L], TNF-α [(3.27±0.38)ng/L], IL-6 [(5.32±1.46)ng/L] and C3a [(12.13±1.62)μg/L] in the observation group were lower than those in the control group [(28.06±2.62)ng/L, (5.13±0.43)ng/L, (6.68±1.51)ng/L and (16.43±1.26)μg/L] ( t=19.618, 33.055, 6.603, 21.367, all P<0.05). The total incidence of complications in the observation group (7.69%) was lower than that in the control group (22.12%) (χ 2=8.529, P<0.05). Conclusion:Escharectomy and skin grafting combined with negative pressure can improve the wound healing rate, improve the body's inflammatory response, shorten the recovery time, reduce the occurrence of complications and has good safety.
