Aims It has been generally accepted that open fractures require early skeletal stabilization and soft-tissue reconstruction. Traditionally, a standard gauze dressing was applied to open wounds. There has been a recent shift in this paradigm towards negative pressure wound therapy (NPWT). The aim of this study was to compare the clinical outcomes in patients with open tibial fractures receiving standard dressing versus NPWT. Methods This multicentre randomized controlled trial was approved by the ethical review board of a public sector tertiary care institute. Wounds were graded using Gustilo-Anderson (GA) classification, and patients with GA-II to III-C were included in the study. To be eligible, the patient had to present within 72 hours of the injury. The primary outcome of the study was patient-reported Disability Rating Index (DRI) at 12 months. Secondary outcomes included quality of life assessment using 12-Item Short-Form Health Survey questionnaire (SF-12), wound infection rates at six weeks and nonunion rates at 12 months. Logistic regression analysis and independent-samples t-test were applied for secondary outcomes. Analyses of primary and secondary outcomes were performed using SPSS v. 22.0.1 and p-values of < 0.05 were considered significant. Results A total of 486 patients were randomized between January 2016 and December 2018. Overall 206 (49.04%) patients underwent NPWT, while 214 (50.95%) patients were allocated to the standard dressing group. There was no statistically significant difference in DRI at 12 months between NPWT and standard dressing groups (mean difference 0.5; 95% confidence interval (CI) -0.08 to 1.1; p = 0.581). Regarding SF-12 scores at 12 months follow-up, there was no significant difference at any point from injury until 12 months (mean difference 1.4; 95% CI 0.7 to 1.9; p = 0.781). The 30-day deep infection rate was slightly higher in the standard gauze dressing group. The non-union odds were also comparable (odds ratio (OR) 0.90, 95% CI 0.56 to 1.45; p = 0.685). Conclusion Our study concludes that NPWT therapy does not confer benefit over standard dressing technique for open fractures. The DRI, SF-12 scores, wound infection, and nonunion rates were analogous in both study groups. We suggest surgeons continue to use cheaper and more readily available standard dressings.

Abstract Purpose Traditionally, previous wound infection was considered a contraindication to secondary skin closure; however, several case reports describe successful secondary wound closure of wounds “preconditioned” with negative pressure wound therapy (NPWT). Although this has been increasingly applied in daily practice, a systematic analysis of its feasibility has not been published thus far. The aim of this study was to evaluate secondary skin closure in previously infected abdominal wounds following treatment with NPWT. Methods Single-center retrospective analysis of patients with infected abdominal wounds treated with NPWT followed by either secondary skin closure referenced to a group receiving open wound therapy. Endpoints were wound closure rate, wound complications (such as recurrent infection or hernia), and perioperative data (such as duration of NPWT or hospitalization parameters). Results One hundred ninety-eight patients during 2013–2016 received a secondary skin closure after NPWT and were analyzed and referenced to 67 patients in the same period with open wound treatment after NPWT. No significant difference in BMI, chronic immunosuppressive medication, or tobacco use was found between both groups. The mean duration of hospital stay was 30 days with a comparable duration in both patient groups (29 versus 33 days, p = 0.35). Interestingly, only 7.7% of patients after secondary skin closure developed recurrent surgical site infection and in over 80% of patients were discharged with closed wounds requiring only minimal outpatient wound care. Conclusion Surgical skin closure following NPWT of infected abdominal wounds is a good and safe alternative to open wound treatment. It prevents lengthy outpatient wound therapy and is expected to result in a higher quality of life for patients and reduce health care costs.

Abstract Background and Aims Diabetes is rapidly increasing in prevalence worldwide and surgery in patients with diabetic foot is becoming more common. Foot complications are a major cause of admissions in diabetic patients, and comprise a disproportionately high number of hospital days because of multiple surgical procedures and prolonged length of stay in hospital. Diabetic foot is an umbrella term for foot problems in patients with diabetes mellitus. Foot disorders such as ulceration, infection and gangrene are the most common, complex and costly sequelae of diabetes mellitus. The optimal therapy for diabetic foot ulcers remains ill-defined. Saline-moistened gauze has been the standard method; however, it has been difficult to continuously maintain a moist wound environment with these dressings. This has led to the development of various hydrocolloid wound gels, which provided more consistent moisture retention. Refinements in topical ointments have resulted in the addition of various pharmacological agents including growth factors and enzymatic debridement compounds. Hyperbaric oxygen therapy and culture skin substitutes are other wound therapies that have been advocated. All these therapies are associated with significant expense and are being utilized in some situations without sufficient scientific evidence demonstrating their efficacy. Therefore, the search for an efficacious, convenient and cost-effective therapy continues. Negative Pressure Wound Therapy (NPWT) is a newer noninvasive adjunctive therapy system that uses controlled negative pressure using Vacuum-Assisted Closure device (VAC) to help promote wound healing by removing fluid from open wounds through a sealed dressing and tubing which is connected to a collection container. The use of sub-atmospheric pressure dressings, available commercially as a VAC device, has been shown to be an effective way to accelerate healing of various wounds. This was aimed to compare wound outcome, limb salvage, and cost effectiveness between Negative pressure wound therapy (NPWT) and Standard moist wound therapy (SMWT) in management of diabetic non ischemic foot ulcers. Methods we performed a cohort study involving 30 patients with active diabetic foot ulcers, in a high volume tertiary referral vascular center. They were divided into 2 groups: 15 patients (group A) were prescribed NPWT and the other 15 patients (group B) received SMWD. During follow up visits, progress of healing was evaluated and documented in the form of change in wound diameter, depth, up or down scaling along UTWC, wound status at 2, 4, 8, and 12 weeks and 4 weekly thereafter till complete epithelialization. Results As regard to ulcer depth there were statistically significant difference between the 2 groups during follow up duration of the study after 4 weeks with group A showing faster decrease in ulcer depth than group B denoting faster formation of granulation tissue. As regard to complete granulation of ulcer there were statistically significant difference between the 2 groups during follow up duration of the study markedly shown after 6 weeks with group A showing complete ulcer granulation faster than group B, with statistically significant difference as regard to number of days on dressing and follow up duration in weeks between the 2 groups with group A showing lesser number of days on dressing and shorter follow up duration in weeks than group B. Conclusion NPWT has a definitive role in promotion of proliferation of granulation tissue, reduction in the wound size, by and rapid clearing of bacterial load. Our data demonstrates that negative pressure wound dressings decrease the wound size more effectively than saline gauze dressings over the first 4 weeks of therapy. It is suggested that NPWT is a cost-effective, easy to use and patient-friendly method of treating diabetic foot ulcers which helps in early closure of wounds, preventing complications and hence promising a better outcome.

Abstract Background: Patients with the inguinal wound infection after arterial surgery remains clinical challenge. Sustaining lymphatic leakage have been shown as a common and potentially serious complication. However, it remains clinical challenge for surgery to deal with this tough problem. Methods: This study describes a hybrid technique of using radical debridement, lateral femoral bypass (LFB) and intra-incisional negative pressure wound therapy (iNPWT) for single-staged treatment of complex inguinal wound infection after arterial surgery (IWI-AS).Results: Between January 2017 and June 2021, 5 IWI-AS cases treated with this new method were identified. Of the patients, 3 were males and 2 were females. The average age was 49.4 years (range, 33 to 77 years). 4 cases suffered emergent operations due to the sudden bleedings. after vascular bypass reconstructions and an average of 2.2 (range:1-3) iNWPT, all cases achieved wound healing at an average duration of 4.6 weeks (range: 3-6weeks). Moreover, all cases showed no bacterial growth and grafts patency as indicated by doppler ultrasound or CT angiography postoperatively. One case did not receive bypass imaging evaluation at postoperative 12 months. Weakness of quadriceps femoris was observed in one case. Conclusion: single-staged therapy of LFB and iNPWT hybridization is a technically handy and effective method for treatment of inguinal wound infection after arterial surgery.

SummaryObjectives: To evaluate negative pressure wound therapy (NPWT) for treatment of complicated wounds in dogs.Study type: Retrospective multicentre study.Materials and methods: Dogs (n = 50) undergoing open wound treatment were classified according to treatment method used: bandage (Group A, n = 7), NPWT (Group B, n = 18), and foam dressing (Group C, n = 25). Pairs of patients matched based on wound conformation, localization, and underlying cause were compared between Group A and C (n = 7 pairs) and between groups B and C (n = 18 pairs) in terms of duration of previous treatment, time to closure, and complications.Results: Signalment, antibiotic medications, antiseptic treatment, and bacterial status of wounds were comparable between groups. The duration of previous treatment was significantly higher in patients assigned to Group B (p = 0.04) compared to Group C, while no significant difference was found between groups A and B. Total time to wound closure was significantly shorter in Group C compared to Group A (p = 0.02) and in Group B compared to Group C (p = 0.003). Wounds treated with NPWT suffered significantly less complications (p = 0.008) and were significantly less septic during treatment (p = 0.016) than wounds treated with a foam dressing.Conclusion: This study shows that time to healing was halved in NPWT treated patients compared to foam dressing treated patients, which in turn healed faster than patients treated with conventional bandage, underlining the value of NPWT therapy for the treatment of complicated wounds.
