ABSTRACT
Objective To explore the value of the use of the vacuum sealing drainage technology (VSD) in the dermatoplasty for large area of cutaneous defects.Methods By a prospective randomized study,64 patients with large area of cutaneous defects were randomly divided into traditional packaging group (dermatoplasty with the traditional dermatoplastic package method,n =32) and VSD group( dermatoplasty with the vacuum sealing drainage technology,n =32).Operating time,survival.rate of skin graft and wound infection were compared between these two groups.Results There was no significant difference in the operation time between the two groups( [77 ± 16]min vs [83 ± 12] min,P =0.06).The survival rate of skin graft and wound infection in VSD group were significantly better than those in traditional packaging group( survival rate of skin graft:(6±1)％ vs (20±7)％,P＜0.001;wound infection cases:1 vs6,P=0.039).Conclusion Treating large area of cutaneous defects by the dermatoplasty with VSD technology could significantly improve clinical efficacy.
