ABSTRACT
Objective@#To explore the effects of scar excision combined with negative-pressure on repair of hypertrophic scar in burn children.@*Methods@#From October 2010 to August 2016, 25 children with hypertrophic scar after deep burn were hospitalized, with scar course ranging from 3 months to 11 years and scar area ranging from 35 to 427 [83(51, 98)]cm2. A total of 35 scars of 25 children were located in trunk (11 scars), upper limb (11 scars), and lower limb (13 scars). All children received scar excision operation and negative-pressure treatment (negative-pressure value ranged from -40 to -20 kPa), among which 6 cases received scar excision operation and negative-pressure treatment for two times for further removal of scars. After scar excision, electronic spring scale was used to measure the tension of the incision. The tension value of children ranged from 3.43 to 23.84 [7.16 (5.59, 9.12)] N, and then the incision was closed with appropriate suture according to the value of the tension. The incision with smaller tension was firstly opened on post operation day (POD) 8. After removing the suture, negative-pressure was conducted to POD 14. The incision with larger tension was firstly opened on POD 12. After removing the suture, biological semi-membrane was used to reduce tension to POD 16. All healed incisions were performed with anti-scar treatment for 1 year and relaxation and fixation for 3 months. General condition of the incision was observed after operation. The reduction percentage of scar area was calculated half-year after operation. The Patient and Observer Scar Assessment Scale was used to record the overall score of scar and scar score of trunk, upper limb, and lower limb before operation and half-year after operation. Data were processed with paired t test and Wilcoxon rank sum test.@*Results@#After removing the suture, all incisions of children healed well without redness, effusion, and rupture. Half-year after operation, the appearance and deformity of incision were obviously improved, and the symptoms including pruritus and pain were basically relieved. Half-year after operation, the scar area of children ranged from 0 to 174 [21(9, 47)]cm2, which was significantly decreased as compared with that before operation (Z=-5.16, P<0.05). The reduction percentage of scar area ranged from 36% to 100% [(73±19)%]. Half-year after operation, the overall score of scar and scar score of trunk, upper limb, and lower limb of children were obviously decreased as compared with those before operation (with t values from 6.42 to 17.37, P values below 0.05).@*Conclusions@#Scar excision combined with negative-pressure treatment has a good clinical effect on repair of hypertrophic scar in burn children, which is suitable for clinical application.
