The application of vacuum sealing drainage in repairing skin of incomplete avulsion

Objective To observe the efficacy of vacuum sealing drainage(VSD) in skin incomplete avulsion and analyze its advantages,disadvantages and summarize the clinical experience for improving VSD clinical application.Methods A total of 18 cases with incomplete avulsion of skin from May 2009 to December 2009 were enrolled,male 11,female 7,aged 16-58 years,mean age 30.6 years.The part potential necrosis tissue was peeled thinner to cribriform and made the full-thickness or intermediate thickness skin graft were prepared and sutured in situ,of these patients 9 were treated by VSD,and 9 were performed by conventional compression bandage.The survival rate of possible necrosis tissue was observed,the data were analyzed by SPSS 13.0.And theoretical analysis were performed for VSD application.Results The survival rate of VSD group was 80.78 % and the conventional group was 82.66 %,there was no significant difference between 2 groups(P 0.1);The early drainage of VSD was complete,but the negative pressure was no benefit on tissue repair,while the conventional compression bandage had more stability and further beneficial to reconstruction of the blood supply.Conclusion It is demonstrated that VSD is an alternative approach in incomplete avulsion of skin,but obvious benefit is not found and the clinical application techniques should be further improved.
