The clinical application of the vacuum sealing drainage technology in the dermatoplasty for large area of cutaneous defects

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.
