Novel Application of Vacuum Sealing Drainage with Continuous Irrigation of Potassium Permanganate for Managing Infective Wounds of Gas Gangrene

Summary： Traumatic gas gangrene is a fatal infection mainly caused by Clostridium perfringens. It is a challenge to manage gas gangrene in open wounds and control infection after debridement or amputa- tion. The aim of the present study was to use vacuum sealing drainage （VSD） with continuous irrigation of potassium permanganate to manage infective wounds of gas gangrene and observe its clinical effi- cacy. A total of 48 patients with open traumatic gas gangrene infection were included in this study. Am- putations were done for 27 patients, and limb salvage procedures were performed for the others. After amputation or aggressive debridement, the VSD system, including polyvinyl alcohol （PVA） foam dress- ing and polyurethane （PU） film, with continuous irrigation of 1：5000 potassium permanganate solutions, was applied to the wounds. During the follow-up, all the patients healed without recurrence within 8-18 months. There were four complications. Cardiac arrest during amputation surgery occurred in one pa- tient who suffered from severe septic shock. Emergent resuscitation was performed and the patient re- turned to stable condition. One patient suffered from mixed infection of Staphylococcal aureus, and a second-stage debridement was performed. One patient suffered from severe pain of the limb after the debridement. Exploratory operation was done and the possible reason was trauma of a local peripheral nerve. Three cases of crush syndrome had dialysis treatment for concomitant renal failure. In conclusion, VSD can convert open wound to closed wound, and evacuate necrotic tissues. Furthermore, potassium permanganate solutions help eliminate anaerobic microenviroument and achieve good therapeutic effect on gas gangrene and mixed infection. VSD with continuous irrigation of potassium permanganate is a novel, simple and feasible alternative for severe traumatic open wounds with gas gangrene infection.

Recombinant human epidermal growth factor combined with vacuum sealing drainage for wound healing in Bama pigs

Background:Vacuum sealing drainage(VSD)and epidermal growth factor(EGF)both play an important role in the treatment of wounds.This study aims to explore the effects of the combination of VSD and EGF on wound healing and the optimal concentration and time of EGF.Methods:We tested the proliferation and migration capacity of HaCaT and L929 cells at different EGF concentrations(0,1,5,10,and 100ng/ml)and different EGF action times(2,10,and 30min).A full-thickness skin defect model was established using male,30-week-old Bama pigs.The experiment included groups as follows:routine dressing change after covering with sterile auxiliary material(Control),continuous negative pressure drainage of the wound(VSD),continuous negative pressure drainage of the wound and injection of EGF 10min followed by removal by continuous lavage(V+E 10min),and continuous negative pressure drainage of the wound and injection of EGF 30min followed by removal by continuous lavage(V+E 30min).The wound healing rate,histological repair effect and collagen deposition were compared among the four groups.Results:An EGF concentration of 10ng/ml and an action time of 10min had optimal effects on the proliferation and migration capacities of HaCaT and L929 cells.The drug dispersion effect was better than drug infusion after bolus injection effect,and the contact surface was wider.Compared with other groups,the V+E 10min group promoted wound healing to the greatest extent and obtained the best histological score.Conclusions:A recombinant human epidermal growth factor(rhEGF)concentration of 10 ng/ml can promote the proliferation and migration of epithelial cells and fibroblasts to the greatest extent in vitro.VSD combined with rhEGF kept in place for 10min and then washed,can promote wound healing better than the other treatments in vitro.

The Application of Bilayer Artificial Dermis Combined with VSD Technology in Chronic Wounds

Background: Bilayer artificial dermis promotes wound healing and offers a treatment option for chronic wounds. Aim: Examine the clinical efficacy of bilayer artificial dermis combined with Vacuum Sealing Drainage (VSD) technology in the treatment of chronic wounds. Method: From June 2021 to December 2023, our hospital treated 24 patients with chronic skin tissue wounds on their limbs using a novel tissue engineering product, the bilayer artificial dermis, in combination with VSD technology to repair the wounds. The bilayer artificial dermis protects subcutaneous tissue, blood vessels, nerves, muscles, and tendons, and also promotes the growth of granulation tissue and blood vessels to aid in wound healing when used in conjunction with VSD technology for wound dressing changes in chronic wounds. Results: In this study, 24 cases of chronic wounds with exposed bone or tendon larger than 1.0 cm2 were treated with a bilayer artificial skin combined with VSD dressing after wound debridement. The wounds were not suitable for immediate skin grafting. At 2 - 3 weeks post-treatment, good granulation tissue growth was observed. Subsequent procedures included thick skin grafting or wound dressing changes until complete wound healing. Patients were followed up on average for 3 months (range: 1 - 12 months) post-surgery. Comparative analysis of the appearance, function, skin color, elasticity, and sensation of the healed chronic wounds revealed superior outcomes compared to traditional skin fl repairs, resulting in significantly higher satisfaction levels among patients and their families. Conclusion: The application of bilayer artificial dermis combined with VSD technology for the repair of chronic wounds proves to be a viable method, yielding satisfactory therapeutic effects compared to traditional skin flap procedures.
