[Clinical effect of double layer vacuum sealing drainage in the treatment of delayed severe infection after calcaneal fracture operation]

Abstract

Objective: To observe the clinical effect of vacuum sealing drainage (VSD) technique and simple dressing change in the treatment of delayed severe infection after calcaneal fracture surgery. Methods: From August 2008 to July 2015 , 73 patients with delayed severe infection were treated after calcaneal fractures 3 months in Department of Foot and Ankle, the Second Hospital of Tangshan City, according to the treatment methods are divided into vacuum sealing drainage group of 38 cases, 35 cases of simple dressing group.Two groups of patients after regular wound debridement debridement and sterilization after vacuum sealing drainage group received double wound VSD dressing group received postoperative dressing, two groups of patients with sensitive antibiotics for treatment.Two groups of patients according to the frequency of dressing change, wound healing time, bacterial clearance time and healing time were compared in stage Ⅱ during the perioperative period. Results: Vacuum sealing drainage group: dressing: 7 times, the wound healing time was 27 days, bacterial culture negative for 8 days, the healing time of 13.5 days of perioperative period; treatment group: 34 times the number of dressing, wound healing time was 44 days, bacterial culture negative for 18 days, the healing time of 17 days of surgery period. Two groups of data were compared with the median, after the rank sum test, the difference was statistically significant (Z values were -6.670, -5.529, -5.011, -3.227, P<0.05). The vacuum sealing drainage group compared with conventional dressing group significantly reduced the number of dressing, wound healing time, healing time was significantly shortened bacterial clearance time and perioperative period Ⅱ. Conclusion: Double VSD is easy , safe and quick, short cure time, less pain, higher quality of late life advantages, compared with the traditional dressing treatment of calcaneal fractures of postoperative delayed severe infection, is a safe and effective method.
