The comparative study on the effect of one-stage skin graft and VSD treatment of second-stage sugery after scar release / 中国医师杂志

ABSTRACT

Objective To investigate the difference of vacuum sealing drainage (VSD) on the effect of one-stage skin graft and second-stage sugery after scar release.Methods A total of 42 patients who wanted to undergo scar release and skin graft was randomly divided to control group (n =21) and VSD treatment group (n =21).The control group implemented skin graft immdiately after scar release while VSD treatment group were treated with VSD for 3 days after scar release and then implemented skin graft.The rate of subcutaneous blood stasis and the survival rate of skin graft were observed at 7 days after skin graft.The condition of grafted skin contracture and hyperplasia after half a year was also observed.Results The incidcnce of subcutaneous blood stasis was significantly lower in the VSD group than that in the control group (P ＜ 0.05).The survival rate of skin grafts was significantly higher in the VSD group than that of the control group (P ＜ 0.05).The score of Vancouver scar was significantly lower in the VSD group than that in the control group (P ＜ 0.05).Conclusions VSD treatment of second-stage sugery after scar release can reduce the occurrence of subcutaneous blood stasis,promotc skin graft survival,reduce postoperative skin graft contracture and improve the prognosis of patients compared to one-stage skin graft.
