Postoperative wound infection in an instrumented spine patient is often disastrous. Management includes implant removal leading to spine instability. Negative pressure wound therapy (NPWT) applied to the spine surgical wound is one of the wound care technique with successful results. We report a case of a man who sustained Chance fracture of Lumbar 1 (L1) vertebra treated with long segment posterior instrumentation, who unfortunately developed Extended-spectrum beta-lactamase (ESBL) positive E. coli infection one month after the operation. After careful debridement of the wound, the implant became exposed. Three cycles of NPWT were applied and the wound healed with granulation tissue completely covering the implant, and thus negating the need to remove the implant. In conclusion, the NPWT is a good alternative in postoperative wound management especially in an instrumented spine patient
Negative-Pressure Wound Therapy

Negative pressure wound therapy has become an important technology in the global field of wound care, and the development of this technology is inseparable from the development and application of negative pressure wound care products. Based on the characteristics of the negative pressure wound therapy products, this paper discusses the key contents that should be considered in the design and evaluation of the negative pressure wound protection products from the aspects of physical and chemical properties, biocompatibility, intended use and risk warning information, in order to provide reference for the development and technical review of such products.

Negative-pressure wound therapy (NPWT) has been used to help wound healing since early 1970s, and it has been used increasingly for treating a wide variety of wounds since the early 1990s and started to popularize in China near the mid 1990s. This technique is different from conventional dressing change, as it controls local humidity, alleviates edema, and improves local circulation all by negative pressure. The method generally involves the application of a dressing on the wound surface, connecting the dressing to a vacuum pump through a tube, and then sealing the wound with adhesive films. Most of the clinicians in China believe that NPWT is helpful in accelerating wound healing, though as yet there is no strong evidence to support it. Therefore, it is necessary to conduct more research to further clarify the mechanism and therapeutic effect of NPWT.

Along with improvements in the embedding materials, continual innovation of the applied technique, and further understanding of therapeutic mechanism, the application scope of negative pressure wound therapy (NPWT) becomes broader, clinical experience in its use becomes more abundant. This issue of the journal highlights 5 papers to introduce the experience and knowledge regarding NPWT technique of the authors.

PURPOSE: Skin graft is the gold standard surgical treatment in burn wound management. Until now, wet to dry dressing is regarded as the traditionally standard dressing for skin graft. But it needs to be changed daily, burdens the patients and medical caring team and is time consuming. The authors apply VAC to skin graft to secure the skin and compared the outcomes with previous standard dressing technique. METHODS: 38 burn patients who underwent skin graft were included in this study. Patients were selected with their consent for inclusion in an experimental group and a control group. Patients in the experimental group received a VAC appliance after split-thickness skin graft, while those in the control group received wet to dry dressing after the procedure. Time to complete epithelization, rates of skin graft taken areas, satisfaction of patients and medical caring team was evaluated. RESULTS: A shorter time to complete epithelization (12.5 days) was observed in the experimental group than in the control group (14.6 days), and a higher rates of skin graft taken areas (89%) was observed in the experimental group when compared with the control group (84.5%), A higher satisfaction of both the patients and doctors was observed in the experimental group, compared to the control group, with all statistical significance (P<0.05). CONCLUSION: VAC shortens epithelization period and elevate skin graft taken rates. It also makes the patients and doctors the comfortable in burn patients. The VAC is an excellent alternative for securing skin graft.

The classification messages of non-powered suction apparatus device (NPSAD) intended for negative pressure wound therapy by CFDA have been analysis and generalized. A set of classification regular patterns of NPSAD have been generalized from its intended use, composition, mechanism, contact area and resorbable characteristic. It is helpful to draw a more consistent classification in NPSAD.

Wound repair has always been one of the key issues of clinical concern. In recent years, negative pressure wound therapy (NPWT) has played an increasingly active role in promoting various wound repairs, not only for the treatment of common acute and chronic wounds, but also for closure of surgical incisions, preparation of wounds before skin transplantation, fixation of skin grafts after transplantation, and treatment of some complex thoracic and abdominal trauma. This review aims to summarize the clinical application of NPWT in wound treatment and the related latest research progress, and to preliminarily discuss its future development prospects.

OBJECTIVETo investigate the clinical effect of subcutaneous undermining dissection with continuous negative pressure drainage for the closure of cystic cavity-type bedsore.

METHODS12 patients with cystic cavity-type bedsore underwent surgical debridement and the wounds were closed after subcutaneous undermining dissection. The negative pressure drainage was put in the deep space. The healing process was observed.

RESULTSCompleted healing was achieved in all the 12 cases. The skin wounds healed after 17-20 days and the deep spaces closed after 36-43 days. 12 cases were followed up for 1 year with no occurrence.

CONCLUSIONSIt is an easy and effective method to treat cystic cavity -type bedsore by subcutaneous undermining dissection with continuous negative pressure drainage.

OBJECTIVE: To evaluate the effect of Vacuum-Assisted Closure (V.A.C.) therapy in stage 3 or 4 pressure ulcers refractory to traditional saline wet gauze dressing. METHOD: Ten patients who had stage 3 or 4 pressure ulcers which were failed to heal with saline wet gauze dressing over 4 weeks were investigated. We treated these subjects with V.A.C. therapy. The length, width and depth of pressure ulcers were evaluated every week for 3 weeks. Soft tissue biopsy from pressure ulcer was taken before starting V.A.C. therapy and after the scheduled therapy was done. RESULTS: The sizes of length, width and depth in pressure ulcer were significantly decreased after one week of V.A.C. application. And then healthy granulation tissue was formed. The length, width and depth of the pressure ulcer were decreased of 40.2%, 42.7% and 79.8% of their original size. Soft tissue biopsy in pressure ulcers was taken in 4 cases, the number and size of capillaries were more increased and inflammatory cells were decreased. CONCLUSION: V.A.C. therapy promoted wound healing and revealed favorable histological changes in pressure ulcers refractory to traditional dressing. We suggest that V.A.C. therapy can be used for the effective management of pressure ulcer.
