ABSTRACT
Objective To investigate the efficacy of adhesive negative pressure suction apparatus in treatment of wound infection after colorectal surgery.Methods From January 2010 to November 2011,consecutive patients with wound infection after colorectal surgery were randomized to the experimental group (n =24 ) and the control group (n =24).The patients in experimental group were treated with the adhesive negative pressure suction apparatus.The patients in the control group were treated with traditional wound therapy.The results of treatment were evaluated.Results Time from debriding the wound infection to secondary suture was significantly shorter in patients of the experimental group ( P ＜ 0.05 ).The total number of dressing changes was very significantly less in patients of the experimental group ( P ＜ 0.01 ).The total cost of dressing in experimental group was significantly less than the control group (P ＜ 0.05 ).Conclusions The application of adhesive negative pressure suction apparatus in treatment of the wound infection after colorectal surgery can shorten the wound processing time,reduce the number of dressing changes and the total cost of dressing,thus has a high clinical value.
