Abstract
Pressure ulcers (PU) are caused by persistent long-term pressure, which compromises the integrity of the epidermis, dermis, and subcutaneous adipose tissue layer by layer, making it difficult to heal. Platelet products such as platelet lysate (PL) can promote tissue regeneration by secreting numerous growth factors based on clinical studies on skin wound healing. However, the components of PL are difficult to retain in wounds. Gelatin methacrylate (GelMA) is a photopolymerizable hydrogel that has lately emerged as a promising material for tissue engineering and regenerative medicine. The PL liquid was extracted, flow cytometrically detected for CD41a markers, and evenly dispersed in the GelMA hydrogel to produce a surplus growth factor hydrogel system (PL@GM). The microstructure of the hydrogel system was observed under a scanning electron microscope, and its sustained release efficiency and biological safety were tested in vitro. Cell viability and migration of human dermal fibroblasts, and tube formation assays of human umbilical vein endothelial cells were applied to evaluate the ability of PL to promote wound healing and regeneration in vitro. Real-time polymerase chain reaction (PCR) and western blot analyses were performed to elucidate the skin regeneration mechanism of PL. We verified PL's therapeutic effectiveness and histological analysis on the PU model. PL promoted cell viability, migration, wound healing and angiogenesis in vitro. Real-time PCR and western blot indicated PL suppressed inflammation and promoted collagen I synthesis by activating STAT3. PL@GM hydrogel system demonstrated optimal biocompatibility and favorable effects on essential cells for wound healing. PL@GM also significantly stimulated PU healing, skin regeneration, and the formation of subcutaneous collagen and blood vessels. PL@GM could accelerate PU healing by promoting fibroblasts to migrate and secrete collagen and endothelial cells to vascularize. PL@GM promises to be an effective and convenient treatment modality for PU, like chronic wound treatment.

Abstract
A male in his early 30s was transported to the emergency room after being hit by a vehicle while inebriated and lying in the street. His general condition was stable; however, he had a perineal laceration that extended to the coccyx. Due to the proximity of the wound margin to the anus, we were concerned regarding the potential contamination and opted not to suture it. Therefore, we refrained from suturing the wound and kept the wound open after irrigation and debridement. Additionally, we performed a transverse colostomy. On day 4, we initiated negative pressure wound therapy for 40 days, during which sufficient wound granulation occurred. The patient was discharged, and the colostomy was closed approximately 4 months after the injury. Our case illustrates the effectiveness of negative pressure wound therapy in managing perineal lacerations.

Abstract
Negative pressure wound therapy (NPWT) is extensively used in clinical settings to enhance the healing of wounds. Despite its widespread use, the molecular mechanisms driving the efficacy of NPWT have not been fully elucidated. In this study, skin wound-healing models were established, with administration of NPWT. Vimentin, collagen I, and MMP9 of skin tissues were detected by immunofluorescence (IF). Gene expression analysis of skin wound tissues was performed by RNA-sequencing (RNA-seq). Protein expression was assayed by a Western blotting or IF assay, and mRNA levels were quantified by quantitative PCR. Chromatin accessibility profiles of fibroblasts following NPWT or IL-17 exposure were analyzed by ATAC-seq. In rat wound-healing models, NPWT promoted wound repair by promoting reepithelialization, extracellular matrix (ECM) synthesis, and proliferation, which mainly occurred in the early stage of wound healing. These differentially expressed genes (DEGs) in NPWT wounds versus control wounds were enriched in the IL-17 signaling pathway. IL-17 was identified as an upregulated factor following NPWT in skin wounds. Moreover, the IL-17 inhibitor secukinumab (SEC) could abolish the promoting effect of NPWT on wound healing. Importantly, chromatin accessibility profiles were altered following NPWT and IL-17 stimulation in skin fibroblasts. Our findings suggest that NPWT upregulates IL-17 to promote wound healing by altering chromatin accessibility, which is a novel mechanism for NPWT's efficacy in wound healing.NEW & NOTEWORTHY To our knowledge, this is the first report of the efficacy of negative pressure wound therapy (NPWT) in promoting wound healing via IL-17. Moreover, NPWT and IL-17 can alter chromatin accessibility. Our study identifies a novel mechanism for NPWT's efficacy in wound healing.

Abstract
Patients with scars face a grave threat to their mental and physical health. Negative pressure has been used for scar therapy in medical care and provides a microenvironment conducive to scar healing while stimulating cell regeneration. Negative pressure may disrupt scar tissue regeneration when the pressure is too high or too low, so finding a suitable negative pressure is important. We hypothesized that different negative pressure magnitudes would affect scar tissue properties differently. This research aimed to provide practical recommendations for scar therapy. This study used three negative pressures (-105 mmHg, -125 mmHg, and -145 mmHg) to compare scar material properties. We measured scar tissue thickness and viscoelasticity with a motor-driven ultrasound indentation system. According to the results of this study, scar thickness is most effectively reduced at a negative pressure of -105 mmHg. In comparison, scar viscoelasticity continuously increases at a negative pressure of -125 mmHg. Negative pressure therapy can be recommended to scar care clinics based on the results of this study.

Abstract
Fracture-related infections are the predominant complication following surgical fracture treatment. The distal lower leg, e.g., in pilon tibial fractures, is at a high risk of infection due to poor soft tissue coverage, particularly in cases of open fractures in this area. Fracture-related infections with significant soft tissue damage require special attention alongside treatment of the infection itself. In general, the principle is that healing of fracture-related infection is not possible without sufficient soft tissue coverage. Therefore, it is crucial to integrate both soft tissue damage and fracture-related infection into a comprehensive treatment plan from the beginning. An interdiscpilinary treatment approach between trauma and plastic surgery is often necessary and beneficial. In cases, where fracture fixation devices or bone is exposed, mid- or long-term use of vacuum-assisted wound therapy is not advisable due to a higher risk of reinfection. Hence, an interdisciplinary treatment strategy involving trauma and plastic surgery should prioritize early soft tissue closure, referred to as the "orthoplastic approach". If this cannot be done in the own hospital, early patient transfer is indicated to ensure optimal interdisciplinary therapy with early soft tissue closure and simultaneous trauma surgical treatment to control the infection and enable bone healing. Free fasciocutaneous or muscle flap techniques in combination with adequate trauma surgical and antibiotic therapy lead to good reliable results in these situations.

Abstract
BACKGROUND Open fractures with extensive soft-tissue damage, significant periosteal stripping, and exposed bone ends pose a significant challenge in orthopaedics. So, we conducted a prospective study that investigated the efficacy of vacuum-assisted closure (VAC) therapy in improving functional outcomes for orthopaedic open wounds. METHODS A prospective case series was conducted for a period of 18 months at the department of orthopaedics. Seventeen patients with open wounds were included in the study after fulfilling specific criteria. The study involved 17 patients with open wounds, where VAC therapy was applied within 24 hours of admission for 14 patients, and for three patients with superficial infection, thorough wound debridement preceded VAC dressing. Follow-up with patients continued until definitive skin cover procedures were performed. RESULTS The majority of cases were attributed to open compound fractures caused by road traffic accidents (82.35%), followed by train traffic accidents (11.76%) and accidental falls (5.88%). The leg (47%) was the most common location of injury, followed by the forearm (23.52%). The average treatment duration was 10.5 days, with an average of 3.3 dressing changes, indicating the efficacy and feasibility of VAC therapy in clinical practice. The average wound size reduction at completion was 15mm, and 15 out of 17 patients achieved successful wound healing. The average time required for forming a uniform granulation bed was 10.5 days, highlighting the efficiency of VAC therapy in promoting tissue regeneration. CONCLUSION Our study findings revealed that there is a significant reduction in the rate of wound infection with the application of VAC therapy, along with a shorter duration for the formation of healthy granulation tissue, rendering the wound suitable for definitive skin cover procedures such as split skin graft and flap cover at an accelerated rate. Additionally, technical challenges associated with applying VAC dressing in the presence of an external fixator were successfully managed through realignment strategies, further underscoring the adaptability and efficacy of VAC therapy in addressing complex wound scenarios.

Abstract
Background Open fractures are common and serious injuries that primarily affect young males. Fracture management has improved in the last decade. However, infections with their complications are still a concern, especially in open fractures for primary closure of the injured area. A newer technique called vacuum-assisted therapy has become a therapy of choice for many orthopedic surgeons. This study aimed to determine whether vacuum-assisted closure reduces the duration of wound healing and the frequency of infections after fixation of Gustilo-Anderson Type IIIA/IIIB fractures of the extremities. Methodology An observational analytical study was conducted among 34 patients with Gustilo-Anderson Type IIIA/IIIB fractures of the limbs who presented to the Department of Orthopaedics, R. L. Jalappa Hospital, Kolar, from December 2019 to July 2021. Negative-pressure wound therapy was employed for wound closure after fixation of fractures. Patients were followed up for one month. Results The mean age of the patients was 37.06 ± 10.340 years. The prevalence of infection before vacuum-assisted closure dressing was 80.6%, and the prevalence of infection after vacuum-assisted closure dressing was 19.4%. The difference in proportion before versus after the intervention was statistically significant (p < 0.001) according to the McNemar Test. Hence, vacuum-assisted closure dressing decreased the rate of infection. The mean dimension of the wound before vacuum-assisted closure therapy was 66.05 cm2 and the mean dimension of the wound after vacuum-assisted closure therapy was 27.97 cm2. The difference in the mean before and after the intervention was statistically significant according to the paired t-test (p < 0.001). Hence, vacuum-assisted closure dressing helped decrease the wound size which was proven statistically. Conclusions Vacuum-assisted closure is a viable and beneficial treatment option for complicated fractures with large soft-tissue abnormalities.

Abstract
INTRODUCTION The susceptibility to surgical site occurrence (SSO) is high following ventral hernia repair (VHR) surgery. SSO severely increases the physical and mental burden on patients. The main purpose of this review was to analyze the efficacy of negative pressure wound therapy (NPWT) after open VHR(OVHR) and explore benefits to patients. METHODS The Cochrane Library, PubMed, and Embase databases were searched from the date of establishment to 15 October 2022. All randomized controlled trials and retrospective cohort studies comparing NPWT with standard dressings after OVHR were included. The Revman 5.4 software recommended by Cochrane and the STATA16 software were used in this meta-analysis. RESULTS Fifteen studies (involving 1666 patients) were identified and included in the meta-analysis, with 821 patients receiving NPWT. Overall, the incidence rate of SSO in the NPWT group was lower compared to the control group (odds ratio [OR] = 0.44; 95% confidence interval [CI] = 0.21-0.93; I2 = 86%; P = 0.03). The occurrence rate of surgical site infection (SSI; OR = 0.51; 95% CI = 0.38-0.68, P < 0.001), wound dehiscence (OR = 0.64; 95% CI = 0. 43-0.96; P = 0.03), and hernia recurrence (OR = 0.51; 95% CI = 0.28-0.91, P = 0.02) was also lowered. There was no significant difference in seroma (OR = 0.76; 95% CI = 0.54-1.06; P = 0.11), hematoma (OR = 0.53; 95% CI = 0.25-1.11; P = 0.09), or skin necrosis (OR = 0.83; 95% CI = 0.47-1.46; P = 0.52). CONCLUSION NPWT can effectively decrease the occurrence of SSO, SSI wound dehiscence and hernia recurrence and should be considered following OVHR.

Li P, Li J. Effect of incisional negative pressure therapy and conventional treatment on wound complications after orthopaedic trauma surgery: A meta-analysis of randomized controlled studies. Int Wound J 2023; 20:4291-4299. [PMID: 37534409 PMCID: PMC10681432 DOI: 10.1111/iwj.14331] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 07/15/2023] [Accepted: 07/16/2023] [Indexed: 08/04/2023] Open
Abstract
The results of this meta-analysis were applied to analyse the effects of Negative Pressure Wound Therapy (NPWT) and conventional dressings on post-surgical outcomes after trauma in orthopaedics. Through June 2023, a full review of the literature has been carried out with the help of 4 databases, PubMed, Embase, Cochrane Library, and the Web of Science. The quality of the literature was evaluated according to the classification and exclusion criteria established for this trial, which led to an analysis of 9 related trials. The results included the injury was deeply and superficially infected, and the wound was dehiscence. The 95% confidence interval (CI) and odds ratios (OR) were computed by means of a fixed-effect and a random-effect model. Meta-analyses were conducted with RevMan 5.3. There is no statistical significance between NPWT and routine therapy for deep wound infection (OR, 1.37; 95% CI, 0.82-2.27, p = 0.23); There was no difference in the incidence of inflammation in the wound than with conventional dressings (OR, 1.10; 95% CI, 0.84-1.45, p = 0.49); But NPWT was obviously superior to that of routine therapy in superficial wound infection (OR, 2.07; 95% CI, 1.32-3.25, p = 0.002) and wound dehiscence (OR, 2.44; 95% CI, 1.31-4.57, p = 0.005); But not with respect to wound exudate. therapy group, but no statistically significant difference was found with respect to wound exudation. (OR, 1.16; 95% CI, 0.86-1.57, p = 0.34). Given that some of the chosen trials are too small for this meta-analysis, caution should be exercised when treating their values. More high-quality research with a large sample is required in order to confirm the findings.

Abstract
PURPOSE Skin closure disorders in ankle surgery are a recurrent problem not only in traumatology but also in elective surgery. The aim of the study was to describe the anatomical basis of the fasciocutaneous vascularization of the lateral malleolus region to develop a posterior cover flap for the region. METHODS We dissected ten fresh frozen specimens after arterial injection of an Indian ink preparation and individualized the perforating arteries. Their positions and diameters were collated. Then, the surgical technique was clinically applied for two different cases by transferring the fasciocutaneous flap posterior to the lateral malleolus to cover a loss of skin substance. RESULTS There were in average 5 fibular perforators over the last 100 mm of the fibula. The average diameter of the first two perforating arteries was 0.6 ± 0.12 mm and 0.9 ± 0.25 mm, respectively, and the consistency of the latter makes it possible to produce a skin flap with anterior translation. This is an axial flap. Two patients were operated on using this technique. There was no necrosis of the posterior fibular flap and healing was achieved by the third post-operative week. CONCLUSION This study showed the presence of fibular perforating arteries with a high reproducibility of their dissection. This anatomical description served as the basis for the description of a new distal fibular perforating flap.

Impact of negative pressure wound treatment on incidence of surgical site infection in varied orthopedic surgeries: A systematic review and meta-analysis. Int Wound J 2023; 20:2334-2345. [PMID: 36524330 PMCID: PMC10333009 DOI: 10.1111/iwj.14043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 11/18/2022] [Accepted: 11/22/2022] [Indexed: 07/20/2023] Open
Abstract
Negative pressure wound therapy (NPWT) is a popular treatment to heal infected wounds. This meta-analysis aimed to determine if NPWT was more effective than conventional wound dressings for surgical site infections (SSI) in varied orthopaedic surgeries. Literature was retrieved from seven electronic databases (Medline, Web of Science, PubMed, Embase, Google Scholar, Cochrane Library, and CNKI). Randomised control trials (RCT) and retrospective cohort studies (RS) involving arthroplasty, fracture, and spinal surgery were extracted. SSI was our primary outcome, while total complications and length of hospital stay were secondary outcomes. We carried out the risk of bias assessment and meta-analysis using the Cochrane Risk of Bias 2.0 tool and Stata 17.0. Among the 798 studies retrieved, 18 of them met our inclusion criteria. We identified 13 RCTs and 5 RSs. The results of meta-analysis showed that the incidence of SSI in the NPWT group was significantly lower relative to the control group (OR = 0.60, 95% CI 0.47 to 0.77, P < 0.001). Subgroup analyses revealed that the incidences of SSI involving arthroplasty, fracture, and spinal surgery in the NPWT group accounted for 46%, 69%, and 37% relative to the control group, respectively. The incidence of SSI in RS (OR = 0.27, 95% CI 0.13 to 0.56) was significantly lower than that in RCT (OR = 0.69, 95% CI 0.54 to 0.90) (P = 0.02). Moreover, patients in the NPWT group had a lower total complication rate (OR = 0.51, 95% CI 0.34 to 0.76) and shorter hospital stays (SMD = -0.42, 95% CI -0.83 to -0.02), although high heterogeneity existed. NPWT may be an efficient alternative to help prevent the incidence of SSI and total complications as well as achieved shorten hospital stay in varied orthopaedic surgeries. The rational use of NPWT should be based on the presence of patients' clinical conditions and relevant risk factors.

Abstract
Background: In recent years, the impact of bacterial biofilms on traumatic wounds and the means to combat them have become a major research topic in the field of medicine. The eradication of biofilms formed by bacterial infections in wounds has always been a huge challenge. Herein, we developed a hydrogel with the active ingredient berberine hydrochloride liposomes to disrupt the biofilm and thereby accelerate the healing of infected wounds in mice. Methods: We determined the ability of berberine hydrochloride liposomes to eradicate the biofilm by means of studies such as crystalline violet staining, measuring the inhibition circle, and dilution coating plate method. Encouraged by the in vitro efficacy, we chose to coat the berberine hydrochloride liposomes on the Poloxamer range of in-situ thermosensitive hydrogels to allow fuller contact with the wound surface and sustained efficacy. Eventually, relevant pathological and immunological analyses were carried out on wound tissue from mice treated for 14 days. Results: The final results show that the number of wound tissue biofilms decreases abruptly after treatment and that the various inflammatory factors in them are significantly reduced within a short period. In the meantime, the number of collagen fibers in the treated wound tissue, as well as the proteins involved in healing in the wound tissue, showed significant differences compared to the model group. Conclusion: From the results, we found that berberine liposome gel can accelerate wound healing in Staphylococcus aureus infections by inhibiting the inflammatory response and promoting re-epithelialization as well as vascular regeneration. Our work exemplifies the efficacy of liposomal isolation of toxins. This innovative antimicrobial strategy opens up new perspectives for tackling drug resistance and fighting wound infections.

Abstract
Background Lower extremity salvage in the setting of severe trauma requires the consideration of multiple surgical specialties and treatment algorithms. We hypothesized that time to first ambulation, ambulation without an assistive device, chronic osteomyelitis, and delayed amputation were not affected by the time to soft tissue coverage in Gustilo IIIB and IIIC fractures at our institution. Methods We evaluated all patients treated for open tibia fractures at our institution from 2007 to 2017. Patients requiring any form of soft tissue coverage to the lower extremity during their initial hospitalization and who had at least 30 days of follow-up from time of hospital discharge were included. Univariable and multivariable analysis was performed for all variables and outcomes of interest. Results Of 575 patients included, 89 required soft tissue coverage. On multivariable analysis, the time to soft tissue coverage, length of negative pressure wound therapy treatment, and number of wound washouts were not found to be associated with development of chronic osteomyelitis, decreased 90-day return to any ambulation, decreased 180-day return to ambulation without assistive device, or delayed amputation. Conclusions Time to soft tissue coverage in open tibia fractures did not affect time to first ambulation, ambulation without an assistive device, chronic osteomyelitis, or delayed amputation in this cohort. It remains difficult to definitively prove that time to soft tissue coverage meaningfully impacts lower extremity outcomes.

Abstract
Acute and chronic wound infection has become a major worldwide healthcare burden leading to significantly high morbidity and mortality. The underlying mechanism of infections has been widely investigated by scientist, while standard wound management is routinely been used in general practice. However, strategies for the diagnosis and treatment of wound infections remain a great challenge due to the occurrence of biofilm colonization, delayed healing and drug resistance. In the present review, we summarize the common microorganisms found in acute and chronic wound infections and discuss the challenges from the aspects of clinical diagnosis, non-surgical methods and surgical methods. Moreover, we highlight emerging innovations in the development of antimicrobial peptides, phages, controlled drug delivery, wound dressing materials and herbal medicine, and find that sensitive diagnostics, combined treatment and skin microbiome regulation could be future directions in the treatment of wound infection.

Abstract
BACKGROUND Management of the open abdomen is a considerable burden for patients and healthcare professionals. Various temporary abdominal closure techniques have been suggested for managing the open abdomen. In recent years, negative pressure wound therapy (NPWT) has been used in some centres for the treatment of non-trauma patients with an open abdomen; however, its effectiveness is uncertain. OBJECTIVES To assess the effects of negative pressure wound therapy (NPWT) on primary fascial closure for managing the open abdomen in non-trauma patients in any care setting. SEARCH METHODS In October 2021 we searched the Cochrane Wounds Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL EBSCO Plus. To identify additional studies, we also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses, and health technology reports. There were no restrictions with respect to language, date of publication, or study setting. SELECTION CRITERIA We included all randomised controlled trials (RCTs) that compared NPWT with any other type of temporary abdominal closure (e.g. Bogota bag, Wittmann patch) in non-trauma patients with open abdomen in any care setting. We also included RCTs that compared different types of NPWT systems for managing the open abdomen in non-trauma patients. DATA COLLECTION AND ANALYSIS Two review authors independently performed the study selection process, risk of bias assessment, data extraction, and GRADE assessment of the certainty of evidence. MAIN RESULTS We included two studies, involving 74 adults with open abdomen associated with various conditions, predominantly severe peritonitis (N = 55). The mean age of the participants was 52.8 years; the mean proportion of women was 39.2%. Both RCTs were carried out in single centres and were at high risk of bias. Negative pressure wound therapy versus Bogota bag We included one study (40 participants) comparing NPWT with Bogota bag. We are uncertain whether NPWT reduces time to primary fascial closure of the abdomen (NPWT: 16.9 days versus Bogota bag: 20.5 days (mean difference (MD) -3.60 days, 95% confidence interval (CI) -8.16 to 0.96); very low-certainty evidence) or adverse events (fistulae formation, NPWT: 10% versus Bogota: 5% (risk ratio (RR) 2.00, 95% CI 0.20 to 20.33); very low-certainty evidence) compared with the Bogota bag. We are also uncertain whether NPWT reduces all-cause mortality (NPWT: 25% versus Bogota bag: 35% (RR 0.71, 95% CI 0.27 to 1.88); very low-certainty evidence) or length of hospital stay compared with the Bogota bag (NPWT mean: 28.5 days versus Bogota bag mean: 27.4 days (MD 1.10 days, 95% CI -13.39 to 15.59); very low-certainty evidence). The study did not report the proportion of participants with successful primary fascial closure of the abdomen, participant health-related quality of life, reoperation rate, wound infection, or pain. Negative pressure wound therapy versus any other type of temporary abdominal closure There were no randomised controlled trials comparing NPWT with any other type of temporary abdominal closure. Comparison of different negative pressure wound therapy devices We included one study (34 participants) comparing different types of NPWT systems (Suprasorb CNP system versus ABThera system). We are uncertain whether the Suprasorb CNP system increases the proportion of participants with successful primary fascial closure of the abdomen compared with the ABThera system (Suprasorb CNP system: 88.2% versus ABThera system: 70.6% (RR 0.80, 95% CI 0.56 to 1.14); very low-certainty evidence). We are also uncertain whether the Suprasorb CNP system reduces adverse events (fistulae formation, Suprasorb CNP system: 0% versus ABThera system: 23.5% (RR 0.11, 95% CI 0.01 to 1.92); very low-certainty evidence), all-cause mortality (Suprasorb CNP system: 5.9% versus ABThera system: 17.6% (RR 0.33, 95% CI 0.04 to 2.89); very low-certainty evidence), or reoperation rate compared with the ABThera system (Suprasorb CNP system: 100% versus ABThera system: 100% (RR 1.00, 95% CI 0.90 to 1.12); very low-certainty evidence). The study did not report the time to primary fascial closure of the abdomen, participant health-related quality of life, length of hospital stay, wound infection, or pain. AUTHORS' CONCLUSIONS Based on the available trial data, we are uncertain whether NPWT has any benefit in primary fascial closure of the abdomen, adverse events (fistulae formation), all-cause mortality, or length of hospital stay compared with the Bogota bag. We are also uncertain whether the Suprasorb CNP system has any benefit in primary fascial closure of the abdomen, adverse events, all-cause mortality, or reoperation rate compared with the ABThera system. Further research evaluating these outcomes as well as participant health-related quality of life, wound infection, and pain outcomes is required. We will update this review when data from the large studies that are currently ongoing are available.

Abstract
BACKGROUND Open fractures of the major long bones are complex limb-threatening injuries that are predisposed to deep infection. Treatment includes antibiotics and surgery to debride the wound, stabilise the fracture and reconstruct any soft tissue defect to enable infection-free bone repair. There is a need to assess the effect of timing and duration of antibiotic administration and timing and staging of surgical interventions to optimise outcomes. OBJECTIVES To assess the effects (risks and benefits) of the timing of antibiotic administration, wound debridement and the stages of surgical interventions in managing people with open long bone fractures of the upper and lower limbs. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and clinical trial registers in February 2021. We also searched conference proceedings and reference lists of included studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) or quasi-RCTs that recruited adults with open fractures of the major long bones, comparing: 1) timings of prophylactic antibiotic treatment, 2) duration of prophylactic antibiotic treatment, 3) timing of wound debridement following injury or 4) timing of the stages of reconstructive surgery. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We aimed to collect data for the following outcomes: limb function, health-related quality of life (HRQoL), deep surgical site infection, delayed or non-union, adverse events (in the short- and long-term course of recovery), and resource-related outcomes. MAIN RESULTS We included three RCTs of 613 randomised participants with 617 open fractures. Studies were conducted in medical and trauma centres in the USA and Kenya. Where reported, there was a higher proportion of men and a mean age of participants between 30 and 34 years old. Fractures were in the upper and lower limbs in one study, and were tibia fractures in two studies; where reported, these were the result of high-energy trauma such as road traffic accidents. No studies compared the timing of antibiotic treatment or wound debridement. Duration of prophylactic antibiotic treatment (1 study, 77 participants available for analysis) One study compared antibiotic treatment for 24 hours with antibiotic treatment for five days. We are very uncertain about the effects of different durations of antibiotic treatment on superficial infections (risk ratio (RR) 1.19, 95% CI 0.49 to 2.87, favours 5 day treatment; 1 study, 77 participants); this was very low-certainty evidence derived from one small study with unclear and high risks of bias, and with an imprecise effect estimate. This study reported no other review outcomes. Reconstructive surgery: timing of the stages of surgery (2 studies, 458 participants available for analysis) Two studies compared the timing of wound closure, which was completed immediately or delayed. In one study, the mean time of delay was 5.9 days; in the other study, the time of delay was not reported. We are very uncertain about the effects of different timings of wound closure on deep infections (RR 0.82, 95% CI 0.37 to 1.80, favours immediate closure; 2 studies, 458 participants), delayed union or non-union (RR 1.13, 95% CI 0.83 to 1.55, favours delayed closure; 1 study, 387 participants), or superficial infections (RR 6.45, 95% CI 0.35 to 120.43, favours delayed closure; 1 study, 71 participants); this was very low-certainty evidence. We downgraded the certainty of the evidence for very serious risks of bias because both studies had unclear and high risks of bias. We also downgraded for serious imprecision because effect estimates were imprecise, including the possibility of benefits as well as harms, and very serious imprecision when the data were derived from single small study. These studies reported no other review outcomes. AUTHORS' CONCLUSIONS We could not determine the risks and benefits of different treatment protocols for open long bone fractures because the evidence was very uncertain for the two comparisons and we did not find any studies addressing the other possible comparisons. Well-designed randomised trials with adequate power are needed to guide surgical and antibiotic treatment of open fractures, particularly with regard to timing and duration of antibiotic administration and timing and staging of surgery.

Abstract
The incidence of open tibia/fibula fractures in the elderly is increasing, but current national guidelines focus on the aggressive treatment of high-energy injuries in younger patients. There is conflicting evidence regarding whether older age affects treatment provision and outcomes in open fractures. The aim of this study was to determine if elderly patients are sustaining a different injury to younger patients and how their treatment and outcomes differ. This may have implications for future guidelines and verify their application in the elderly. In this retrospective single centre cohort study (December 2015-July 2018), we compared the injury characteristics, operative management and outcomes of elderly (≥65 years) and younger (18-65 years) patients with open tibia/fibula fractures. An extended cohort examined free flap reconstruction. In total, 157 patients were included. High-energy injuries were commoner in younger patients (88% vs 37%; p<0.001). Most were Gustilo-Anderson IIIb in both age groups. Elderly patients waited longer until debridement (21:19 vs 19:00 h) and had longer inpatient stays (23 vs 15 days). There was no difference in time to antibiotics, operative approach or post-operative complications. Despite the low-energy nature of elderly patients' injuries, the severity of soft tissue insult was equivalent to younger patients with high-energy injuries. Our data suggest that age and co-morbidities should not prohibit lower limb reconstruction. The current application of generic guidelines appears suitable in the elderly, particularly in the acute management. We suggest current management pathways and targets be reviewed to reflect the greater need for peri-operative optimisation and rehabilitation in elderly patients.

Cost analysis of negative-pressure wound therapy versus standard treatment of acute conflict-related extremity wounds within a randomized controlled trial. World J Emerg Surg 2022; 17:9. [PMID: 35144650 PMCID: PMC8832805 DOI: 10.1186/s13017-022-00415-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 01/30/2022] [Indexed: 11/15/2022] Open
Abstract
Background Clinical outcomes after negative-pressure wound therapy (NPWT) and standard treatment of conflict-related extremity wounds are similar. In resource-limited settings, cost affects the choice of treatment. We aimed to estimate treatment-related costs of NPWT in comparison with standard treatment for conflict-related extremity wounds. Methods We derived outcome data from a randomized, controlled superiority trial that enrolled adult (≥ 18 years) patients with acute (≤ 72 h) conflict-related extremity wounds at two civilian hospitals in Jordan and Iraq. Primary endpoint was mean treatment-related healthcare costs (adjusted to 2019 US dollars).
Results Patients were enrolled from June 9, 2015, to October 24, 2018. A total of 165 patients (155 men [93.9%]; 10 women [6.1%]; and median [IQR] age, 28 [21–34] years) were included in the analysis. The cost per patient treated with NPWT was $142 above that of standard treatment. Overall, results were robust in a sensitivity analysis. Conclusions With similar clinical outcomes compared to standard care, our results do not support the use of NPWT in routine treatment of conflict-related extremity wounds at civilian hospitals in resource scarce settings. Trial registration NCT02444598.

Negative-pressure wound therapy is effective for peritoneal dialysis catheter exit-site management in the early postoperative period. Sci Rep 2022; 12:70. [PMID: 34996968 PMCID: PMC8742026 DOI: 10.1038/s41598-021-03878-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 12/07/2021] [Indexed: 11/16/2022] Open
Abstract
Peritoneal dialysis (PD) catheter exit-site care is critically important for the prevention of catheter-related infections (CRIs) and subsequent peritonitis. The postoperative management of the site is particularly essential because it has an open wound that is always adjacent to a PD catheter tube. This study aimed to examine the effectiveness of negative-pressure wound therapy (NPWT) for postoperative PD catheter exit sites. Thirty patients with end-stage renal disease who underwent simultaneous PD catheter insertion and exit-site formation were randomly assigned to receive NPWT (NPWT group) or conventional dressing (non-NPWT group) for the first seven postoperative days. The exit-site scores on the seventh postoperative day was lower in the NPWT group than in the non-NPWT group (p = 0.0049). Analysis of variance F statistic for the effect of NPWT over 180 days was highly significant (11.482595, p = 0.007). There were no statistically significant differences between the time to first CRI and PD-related peritonitis between the two groups. There was one case of CRI with relapsing peritonitis and catheter loss in the non-NPWT group. These findings demonstrate the association between NPWT and low exit-site score. NPWT can be recommended for the management of PD catheter exit sites in the early postoperative period.

Abstract
Infections of burn wounds, especially those caused by Pseudomonas aeruginosa, could trigger sepsis or septic shock, which is the main cause of death after burn injury. Compared with traditional saline-wet-to-dry dressings, negative pressure wound therapy (NPWT) is more effective for the prevention and treatment of wound infections. However, the mechanism by which NPWT controls infection and accelerates wound healing remains unclear. Accordingly, in this study, the molecular mechanisms underlying the effects of NPWT were explored using a murine model of P. aeruginosa-infected burn wounds. NPWT significantly reduced P. aeruginosa levels in wounds, enhanced blood flow, and promoted wound healing. Additionally, NPWT markedly alleviated wound inflammation and increased the expression of wound healing–related molecules. Recent evidence points to a role of circular RNAs (circRNAs) in wound healing; hence, whole-transcriptome sequencing of wound tissues from NPWT and control groups was performed to evaluate circRNA expression profiles. In total, 12 up-regulated and 25 down-regulated circRNAs were identified between groups. Among these, five significant differentially expressed circRNAs acting as microRNA sponges were identified, and their predicted targets were verified by reverse transcription-quantitative polymerase chain reaction. These results further support the roles of circRNAs in wound healing by NPWT and the prevention of P. aeruginosa infection, providing key molecular targets for further functional analyses.

Abstract
This study aimed to systematically review the current literature on studies using negative pressure wound therapy (NPWT) or dressings following fracture-related infection (FRI) in internal osteosynthesis of the extremity. Articles were analyzed on fracture and wound healing and included when comparing or describing the use of either NPWT or dressings in FRI. We conducted a systematic literature search in four electronic databases: Embase, Medline, the Cochrane Library, and Scopus. The studies were screened by two authors using Covidence.org and evaluated for risk of bias. A total of 8576 records were identified. No articles compared NPWT to dressings. Seven case reports and three case series included a total of 115 patients treated for FRI. Fracture healing was achieved in 21 out of 67 patients treated with NPWT (4 amputations and 46 not described) and all 48 patients in the dressing group (4 patients needed additional sequestrectomy procedures). Five studies did not describe fracture healing. In 57 out of 67 patients treated with NPWT, the wounds were described as healed, closed, or requiring soft tissue reconstruction (4 amputations and six lacking description). The dressing group had complete wound coverage in 18 patients and partial coverage in 30 patients. Studies were generally at high risk of bias because of insufficient descriptions of both patient demographics and outcomes. No studies compared NPWT to dressings, and the existing literature is at high risk of bias. The included studies were of low-level evidence. NPWT can be neither recommended nor advised against to cover infected osteosynthesis.

Abstract
BACKGROUND Low cost Negative Pressure Wound Therapy (NPWT) dressings have been considered as an alternative to traditional daily dressings. There is scanty literature evaluating the change in the percentage area of wound covered by granulation tissue following application of low-cost NPWT. The change in the bacteriological flora following application of low-cost NPWT devices has also not been evaluated. METHODS Patients above the age of 18 years with acute musculoskeletal injuries of <3 weeks duration which underwent a surgical debridement and required subsequent wound coverage were included in the study. Area of the wound and the area covered by the granulation tissue as well as the bacteriological count were measured before and after application of NPWT. A low cost NPWT using wall mounted vacuum device was put on the patient giving a constant negative pressure of 125 mm of Hg for 2 days. The findings before and after application of NPWT were compared and analyzed using Wilcoxin Signed-rank test. RESULTS 21 patients with mean age of 35.52±15.075 were included. The pre-NPWT granulation tissue area ranged from 122 mm2 to 8483 mm2 with a mean of 1648.38 mm2 (SD = 1933.866). The post-NPWT granulation tissue area ranged from 234 mm2 to 7847 mm2 with a mean of 2364.48 mm2 (SD = 1857.716). The mean increase in granulation tissue was 716.1 mm2.The pre-NPWT wound area ranged from 422 mm2 to 10847 mm2 with a mean of 4009.62 mm2 (SD = 3026.209). The post-NPWT wound area ranged from 326 mm2 to 9143 mm2 with a mean of 3410.33 mm2 (SD = 2636.206). The mean reduction in wound size was 599.29 mm2.The pre-NPWT bacteriological count ranged from 3000/ml to 130000000/ml with a mean of 12616761.90/ml (SD = 29664589.37). The post-NPWT bacteriological count ranged from 1000/ml to 380000000/ml with a mean of 26401523.81/ml. The mean increase in bacteriological count was 13784761.91/ml. CONCLUSION There was a statistically significant decrease in wound size (p = 0.001) and statistically significant increase in percentage area of granulation tissue coverage (p = 0.000) following low cost NPWT application. However there was no statistically significant increase in bacteriological clearance in these patients.

Abstract
INTRODUCTION Fracture-related infection (FRI) is a severe musculoskeletal complication in orthopedic trauma surgery, causing challenges in bony and soft tissue management. Currently, negative-pressure wound therapy (NPWT) is often used as temporary coverage for traumatic and surgical wounds, also in cases of FRI. However, controversy exists about the impact of NPWT on the outcome in FRI, specifically on infection recurrence. Therefore, this systematic review qualitatively assesses the literature on the role of NPWT in the management of FRI. METHODS A literature search of the PubMed, Embase, and Web of Science database was performed. Studies that reported on infection recurrence related to FRI management combined with NPWT were eligible for inclusion. Quality assessment was done using the PRISMA statement and the Newcastle-Ottawa Quality Assessment Scale. RESULTS After screening and quality assessment of 775 unique identified records, eight articles could be included for qualitative synthesis. All eight studies reported on infection recurrence, which ranged from 2.8% to 34.9%. Six studies described wound healing time, varying from two to seven weeks. Four studies took repeated microbial swabs during subsequent vacuum dressing changes. One study reported newly detected pathogens in 23% of the included patients, and three studies did not find new pathogens. CONCLUSION This review provides an assessment of current literature on the role of NPWT in the management of soft tissue defects in patients with FRI. Due to the lack of uniformity in included studies, conclusions should be drawn with caution. Currently, there is no clear scientific evidence to support the use of NPWT as definitive treatment in FRI. At this stage, we can only recommend early soft tissue coverage (within days) with a local or free flap. NPWT may be safe for a few days as temporarily soft tissue coverage until definitive soft tissue management could be performed. However, comparative studies between NPWT and early wound closure in FRI patients are needed.

Abstract
Objective To evaluate the clinical application and surgical efficacy of the chimeric perforator flap pedicled with the descending branch of the lateral circumflex femoral artery and the lateral thigh muscle flap for the reconstruction of the large area of deep wound in foot and ankle. Methods Clinical data of 32 cases who underwent chimeric anterolateral thigh perforator flap to repair the large area of deep wound of the foot and ankle from January 2015 to December 2018 were retrospectively analyzed. The sizes of the defects ranged from 18 cm × 10 cm to 35 cm × 20 cm, with exposed tendon and bone and/or partial defects and necrosis, contaminations, accompanied by different degrees of infection. Following the radical debridement and VSD, chimeric anterolateral thigh perforator flap was employed to repair the deep wounds according to the position, site and deep‐tissue injury of the soft‐tissue defects. The skin flap and muscle flap were fanned out on the wound, and single‐ or two‐staged split‐thickness skin grafting was performed on the muscle flap. The operation time and blood loss were recorded. The survival and healing conditions of the operational site with chimeric anterolateral thigh perforator flap were evaluated post‐operationally. Complications at both recipient site and donor site were carefully recorded. Results The mean time of the operation was 325.5 min and average blood loss was 424.8 mL. Among the 32 cases, two cases developed vascular crisis, which were alleviated with intensive investigation and treatment; Four cases suffered from partial necrosis of the flap or skin graft on the muscle flap or on the residual local wound, which were improved after treatment of further dressing change and skin grafting. Another four cases experienced post‐traumatic osteomyelitis accompanied by bone defect were treated with simple bone grafting or Mesquelet bone grafting at 6–8 months after wound healing. Postoperatively, the wounds were properly healed, and the infection was effectively controlled without sinus tract forming. Overall, all 32 cases received satisfactory efficacy, without influencing subsequent functional reconstruction, and observed infection during the 12–36 months post‐operational follow‐up. Conclusion The chimeric perforator flap pedicled with the descending branch of the lateral circumflex femoral artery and the lateral thigh muscle flap provides an effective and relative safe procedure for the repair of a large area of deep wound in the foot and ankle, particularly with irregular defect or deep dead space.

Abstract
Negative pressure wound therapy (NPWT) has been recognized as an effective method for the treatment of intractable wounds. However, its effects on bone healing remain to be elucidated. Our previous study demonstrated that NPWT induced cell proliferation and osteoblastic differentiation of rat periosteum-derived mesenchymal stem cells (P-MSCs). It was reported that following NPWT treatment, the expression of the mechanotransduction molecule integrin β5 is increased, indicating that NPWT may serve an active role in fracture healing by enhancing bone formation and reducing bone resorption. The present study sought to further investigate the efficacy of NPWT on the bone regeneration process in a rabbit radial gap-healing model. All rabbits with radial defects were randomly divided into two groups: NPWT and control groups. Continuous negative pressure at -125 mmHg was applied to all rabbits. Furthermore, X-ray imaging and scoring on day 7, 14, 21 and 28 postoperatively were performed to evaluate new bone formation. Histological changes were determined via hematoxylin and eosin and Masson's trichrome staining at 2- and 4-weeks following surgery. In addition, vimentin-positive cells located in the periosteum were detected via immunohistochemical examination on day 3 post operation. Finally, protein expression levels of vascular endothelial growth factor (VEGF), bone morphogenetic protein (BMP)-2 and osteopontin (OPN) were evaluated using western blot analysis on the 2nd and 4th week following NPWT. X-ray and histological examination revealed that the bone-healing processes in the NPWT group were faster compared with the control group. Additionally, compared with the control group, the NPWT group exhibited higher X-ray scores, increased percentage of positive vimentin-stained cells and upregulated expression of VEGF, BMP-2 and OPN proteins. The aforementioned findings suggest that NPWT, under a continuous negative pressure of -125 mmHg, may accelerate bone regeneration by enhancing MSC proliferation, osteoblastic differentiation and VEGF, BMP-2 and OPN expression.

Abstract
BACKGROUND Negative pressure wound therapy (NPWT) is a widely used method of wound treatment. We performed a systematic review of randomised controlled trials (RCTs) comparing the patient-relevant benefits and harms of NPWT with standard wound therapy (SWT) in patients with wounds healing by secondary intention. METHODS We searched for RCTs in MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and study registries (last search: July 2018) and screened reference lists of relevant systematic reviews and health technology assessments. Manufacturers and investigators were asked to provide unpublished data. Eligible studies investigated at least one patient-relevant outcome (e.g. wound closure). We assessed publication bias and, if feasible, performed meta-analyses, grading the results into different categories (hint, indication or proof of a greater benefit or harm). RESULTS We identified 48 eligible studies of generally low quality with evaluable data for 4315 patients and 30 eligible studies with missing data for at least 1386 patients. Due to potential publication bias (proportion of inaccessible data, 24%), we downgraded our conclusions. A meta-analysis of all wound healing data showed a significant effect in favour of NPWT (OR 1.56, 95% CI 1.15 to 2.13, p = 0.008). As further analyses of different definitions of wound closure did not contradict that analysis, we inferred an indication of a greater benefit of NPWT. A meta-analysis of hospital stay (in days) showed a significant difference in favour of NPWT (MD - 4.78, 95% CI - 7.79 to - 1.76, p = 0.005). As further analyses of different definitions of hospital stay/readmission did not contradict that analysis, we inferred an indication of a greater benefit of NPWT. There was neither proof (nor indication nor hint) of greater benefit or harm of NPWT for other patient-relevant outcomes such as mortality and adverse events. CONCLUSIONS In summary, low-quality data indicate a greater benefit of NPWT versus SWT for wound closure in patients with wounds healing by secondary intention. The length of hospital stay is also shortened. The data show no advantages or disadvantages of NPWT for other patient-relevant outcomes. Publication bias is an important problem in studies on NPWT, underlining that all clinical studies need to be fully reported.

Abstract
Open fractures with soft-tissue loss remain challenging injuries to treat. These often high-energy fractures are at a higher risk of delayed healing and at much higher risk of infection than open fractures with less significant soft-tissue injury. The initial management of the open wound, flap coverage options, and the timing of definitive coverage all remain areas of controversy, which will be discussed in this article.

Abstract
The simultaneous exposure of tissue and bone poses specific management challenges. Patients with extended soft tissue damage and high-grade compound fractures present a demanding clinical challenge, requiring a complex approach and multiple orthopaedic, plastic, and vascular-reconstructive procedures. Management involves combinations of wound debridement and closure by secondary intention, use of vacuum-assisted closure (VAC) devices, and various reconstructive plastic surgery methods. We present three consecutive complicated cases, involving compound fractures of the lower limb with massive soft tissue damage (Gustilo-Anderson type IIIB) that were managed with debridement, application of external fixation and VAC device. The mean wound size was 24 cm in length and 12 cm in width. The aim of treatment was to cover the bone with soft tissue and achieve healing of the fracture without persistent infection. Wound healing was achieved in all three cases within 30-42 days (mean 34). In one case, the skin graft was applied on day 33. Utilizing this method as part of a multi-directional approach, the VAC system helps the patient recover faster. Moreover, it acts as a feasible and valuable method to treat compound fractures with massive soft-tissue defects. VAC can replace microsurgical soft-tissue transfer, reduce the risk of infection and allow salvaging the limb.

Abstract
Osteomyelitis (OM) of the lower limb represents a large unmet global healthcare burden. It often arises from a contiguous focus of infection and is a recognized complication of open fractures or their surgical treatment, arthroplasty, and diabetic foot ulcers. Historically, this debilitating condition is associated with high rates of recurrence and secondary amputation. However, excellent long-term outcomes are now achieved by adopting a multidisciplinary approach with meticulous surgical debridement, skeletal and soft tissue reconstruction, and tailored antimicrobial treatment. This review focuses on the modern evidence-based management of post-traumatic OM in the lower limb from a reconstructive plastic surgery perspective, highlighting the latest developments and areas of controversy.

Abstract
INTRODUCTION Chronic, nonhealing skin wounds claim >3% of the health-care budget in industrialized countries, and the incidence is rising. Currently, two parallel trends influence innovations within the field of wound healing: the need to reduce spread of antibiotic resistance and the emerging use of health economy and value-based models. Areas covered: This review focuses on the discovery of drug candidates and development of treatments aiming to enhance wound healing in the heterogeneous group of patients with nonhealing wounds. Expert opinion: Nonhealing wounds are multifaceted and recognized as difficult indications. The majority of products currently in use are medical device dressings, or concepts of negative pressure or hyperbaric oxygen treatment. Global best practice guidelines for the treatment of diabetic foot ulcers recommend debridement, redressing, as well as infection control, and are critical to the lack of coherent clinical evidence for many approved products in active wound care. To accelerate wound healing, there is an emerging trend toward biologics, gene therapy, and novel concepts for drug delivery in research and in the pipeline for clinical trials. Scientific delineation of the therapeutic mechanism of action is, in our opinion, vital for clinical trial success and for an increased fraction of medical products in the pharmaceutical pipeline.

Abstract
Objective: Nonviable necrotic eschar is an impedance to wound healing and can ultimately lead to failure of soft tissue coverage in traumatic or high-risk wounds. Topical therapeutic agents can provide a less invasive management alternative to surgical debridement of eschar. Approach: The case of a 40-year-old male with a traumatic right lower extremity amputation complicated by surgical incision ischemic eschar formation is reported. Honey-based salve with burdock leaf dressings was used to noninvasively manage eschar extending over the incision site. Images were obtained for 5 months of follow-up. Results: Five-month follow-up demonstrated complete resolution of eschar and re-epithelialization of skin in the affected region. Innovation: Honey-based salve with burdock leaf dressings shows promise for enhancing healing outcomes in traumatic wounds that develop nonviable eschar. Conclusion: Surgical debridement of an amputation stump with large ischemic eschar was avoided with the use of honey-based salve with burdock leaf dressings.

Abstract
Background In armed conflict, injuries commonly affect the extremities and contamination with foreign material often increases the risk of infection. The use of negative-pressure wound therapy has been described in the treatment of acute conflict-related wounds, but reports are retrospective and with limited follow-up. Objective The objective of this study is to investigate the effectiveness and safety of negative-pressure wound therapy use in the treatment of patients with conflict-related extremity wounds. Methods This is a multisite, superiority, pragmatic randomized controlled trial. We are considering for inclusion patients 18 years of age and older who are presenting with a conflict-related extremity wound within 72 hours after injury. Patients are block randomly assigned to either negative-pressure wound therapy or standard treatment in a 1:1 ratio. The primary end point is wound closure by day 5. Secondary end points include length of stay, wound infection, sepsis, wound complications, death, and health-related quality of life. We will explore economic outcomes, including direct health care costs and cost effectiveness, in a substudy. Data are collected at baseline and at each dressing change, and participants are followed for up to 3 months. We will base the primary statistical analysis on intention-to-treat. Results The trial is ongoing. Patient enrollment started in June 2015. We expect to publish findings from the trial by the end of 2019. Conclusions To the best of our knowledge, there has been no randomized trial of negative-pressure wound therapy in this context. We expect that our findings will increase the knowledge to establish best-treatment strategies.
