Vacuum-assisted closure for chronic wounds: An analysis of 12 cases / 医学研究生学报

ABSTRACT

Objective: Vacuum-assisted closure(VAC) is a new technique for wound treatment,whose clinical application at home is but at the initial stage.The aim of this study was to investigate the procedure,therapeutic course and the effectiveness of the technique in the treatment of chronic wounds.Methods: This study included 12 cases of chronic or infected wound,which were more than 100 cm2 in size,either undermined,or drainage-obstructed,or difficult to heal despite over a month of previous treatment.We used the Freedom Negative Pressure Wounds Therapy Machine and the Ten-Step Management Procedure for a regular course of 30-50 days.We recorded and analyzed the pre-and post-treatment PUSH(pressure ulcer scale for healing) scores,healing modes,healing time and cure rate of all the cases.Results: The 12 cases were treated by VAC for(27.7 ? 22.6) days,of which 9 were cured,1 improved and 2 healed after moisture therapy followed by further treatment in the surgical department.The average healing time was(59.36 ? 22.88) days and the total cure rate was 91.7%.Age is positively correlated with healing time,but other factors showed no significant correlation with healing time and cure rate.Conclusion: The VAC technique is applicable to chronic wounds in patients of all ages,and the best therapeutic course is 30-50 days,which helps to raise the cure rate of intractable wounds.
