RESUMO
OBJECTIVE: To compare the effectiveness of a temporary topical external haemostat (OMNI-STAT Granules, Omni-stat Medical Inc., US) versus the use of electrocautery for bleeding control in patients who have undergone surgical wound debridement. Time saved in the operating room (OR) was evaluated. METHOD: A prospective evaluation of use of a topical haemostat in an OR setting was compared with retrospective data collected using electrocautery to understand the time-saving benefits of using a topical haemostat versus electrocautery. RESULTS: A total of 52 patients were treated with the topical haemostat, and 89 patients with electrocautery. The topical haemostat was shown to be as effective in achieving haemostasis post-surgical debridement as electrocautery, with the added benefits of significant time savings in the OR (reducing the mean total OR time by 19.1%). Additionally, preprocedure and surgical procedure times in patients treated with the topical haemostat were significantly reduced. The results showed that wounds treated with the topical haemostat demonstrated a more advanced stage of healing, which may be a result of the lack of tissue damage demonstrated with the topical haemostat compared with electrocautery. CONCLUSION: This study found that the temporary topical haemostat was equally as effective as cauterisation in achieving haemostasis. In addition, significant saving in OR time was demonstrated relative to electrocautery. The improved OR times may translate into increased cost-effectiveness, relative to electrocautery, by increasing the number of surgical cases per day and/or using resources more effectively to treat more patients. It may also enable bleeding control in the outpatient clinic or at the bedside, freeing up costly OR time and enabling more effective management of healthcare resources.

OBJECTIVE: A pandemic afflicts the entire world. The highly contagious SARS-CoV-2 virus originated in Wuhan, China in late 2019 and rapidly spread across the entire globe. According to the World Health Organization (WHO), the novel Coronavirus (COVID-19)has infected more than two million people worldwide, causing over 160,000 deaths. Patients with COVID-19 disease present with a wide array of symptoms, ranging from mild flu-like complaints to life threatening pulmonary and cardiac complications. Older people and patients with underlying disease have an increased risk of developing severe acute respiratory syndrome (SARS) requiring mechanical ventilation. Once intubated, mortality increases exponentially. A number of pharmacologic regimens, including hydroxychloroquine-azithromycin, antiviral therapy (eg, remdesevir), and anti-IL-6 agents (e.g., toclizumab), have been highlighted by investigators over the course of the pandemic, based on the therapy's potential to interrupt the viral life-cycle of SARS-CoV-2 or preventing cytokine storm. At present, there have been no conclusive series of reproducible randomised clinical trials demonstrating the efficacy of any one drug or therapy for COVID-19. CASES: COVID-19 positive patients (n=5) at a single institution received hyperbaric oxygen therapy (HBOT) between 13 and 20 April 2020. All the patients had tachypnoea and low oxygen saturation despite receiving high FiO2. HBOT was added to prevent the need for mechanical ventilation. A standard dive profile of 2.0ATA for 90 minutes was employed. Patients received between one and six treatments in one of two dedicated monoplace hyperbaric chambers. RESULTS: All the patients recovered without the need for mechanical ventilation. Following HBOT, oxygen saturation increased, tachypnoea resolved and inflammatory markers fell. At the time of writing, three of the five patients have been discharged from the hospital and two remain in stable condition. CONCLUSION: This small sample of patients exhibited dramatic improvement with HBOT. Most importantly, HBOT potentially prevented the need for mechanical ventilation. Larger studies are likely to define the role of HBOT in the treatment of this novel disease.

Impaired wound healing is estimated to affect about 2% of the US population, and a major goal of health care providers (HCPs) is to better understand delayed healing so they can effectively choose advanced wound dressings to manage these wounds. However, there are estimated to be more than 3000 dressing options available, making dressing selection an overwhelming burden. An expert panel of 7 HCPs experienced in diverse medical disciplines and 3 scientists convened to discuss the use of 2 families of dressings (silver-oxysalt [AgOx] dressings and oxidized regenerated cellulose/collagen [ORC/C] dressings) and delayed wound healing. Before the meeting, panelists reviewed 16 articles concerning the dressings, and 2 scientists presented on the topics of infection and inflammation in the wound environment, along with providing information about the dressing families, during the meeting. In addition, each HCP presented specific cases in which they had applied AgOx or ORC/C dressings and described how the dressing was used to manage stalled healing. After the meeting, the panelists and another HCP who was unable to attend the panel meeting provided insight and feedback for this publication, which provides an overview of the meeting. A major theme of this panel discussion was the need for a fundamental change in how HCPs approach wound care, especially for nonhealing wounds and underlying issues of infection and inflammation in the wound environment. Ultimately, the panel developed a decision-tree model for risk-stratifying patients based on their potential to have or develop these 2 underlying issues, followed by deciding on treatment options based on the status of infection and inflammation in the wound.
RESUMO
BACKGROUND: Biofilm can impair wound healing by maintaining an elevated, but ineffective, inflammatory state. This article describes interim results from the prospective RESPOND postmarketing registry evaluating the use of a native type 1, porcine collagen matrix with the embedded antimicrobial polyhexamethylene biguanide (PCMP) in the management of chronic wounds. METHODS: Adults ≥18 years of age with ≥1 appropriate wound were eligible for inclusion. Data that were final on January 26, 2018 were included in this analysis. At week 0, wounds were cleaned, debrided, and prepared as necessary and PCMP was applied, with a dressing to fix it in place. Patients received standard wound care plus PCMP weekly, up to 24 weeks, at the investigator's discretion. At each visit, wounds were assessed for area and quality of granulation tissue. RESULTS: Most common wound types (N = 63) were venous ulcers (28.6%), trauma and lacerations (22.2%), postsurgical open wounds (15.9%), pressure injuries (12.7%), and diabetic ulcers (9.5%). Median baseline wound area was 6.5 cm2; mean wound duration at baseline was 4 months. Of the 63 wounds, 43 (68.3%) achieved complete wound closure, 41 of 43 (95.3%) closed after PCMP treatment, and 2 of 43 (4.7%) after bridging to other modalities and surgical closure. Twelve out of 63 wounds were bridged to other modalities after PCMP treatment. Mean time to closure for PCMP wounds was 5.0 weeks. CONCLUSIONS: PCMP appears to be a useful adjunct for treating various wound types. PCMP use should be considered when managing chronic or acute wounds.
RESUMO
Use of ultra-portable, mechanically powered disposable negative pressure wound therapy (dNPWT) has grown as an adjunctive modality to manage wounds in outpatient care and to expedite transition of inpatients to an outpatient setting. This technology has demonstrated similar efficacy and usability for mobile outpatients when compared with electrically powered negative pressure wound therapy devices. It was designed for patients with smaller, low to moderately exudating wounds and does not require batteries or a power source. However, very few studies address best practices for using dNPWT in a variety of wound types. There is a need for comprehensive clinical recommendations to better direct clinicians and patients in using this therapy. In addition, it is critical that providers are knowledgeable about processes for obtaining reimbursement for placement of dNPWT since codes and procedures differ drastically from standard NPWT. A panel meeting of experts with a high level of experience with dNPWT in varied wound types was convened to develop clinical recommendations and summarize current US reimbursement coding guidelines for the use of dNPWT. This publication summarizes the recommendations from panel members, in addition to supporting evidence, to help guide appropriate use of dNPWT. Panel recommendations regarding optimal patient and wound selection, wound preparation, proper patient training, and use of dNPWT in various wound types are included as well as clinical techniques for dressing application, bridging under offloading devices and compression, maintaining a seal, and protecting intact skin. Processes and codes for obtaining reimbursement for dNPWT are reviewed by care setting. Clinical recommendations and reimbursement guidelines summarized in this publication are meant to provide direction to clinicians in using dNPWT that potentially could translate into improved clinical and economic value.

The increase in wound prevalence means more patients with wounds are being transferred through care settings than ever before. Although the goals of therapy may be the same in both settings, wound care therapies and dressings differ in availability and appropriateness for each setting. Negative pressure wound therapy (NPWT) modalities and oxidized regenerated cellulose (ORC)/collagen (C)/silver-ORC dressings are available in both inpatient and outpatient care settings, but (to-date) lack comprehensive information regarding best practices in transitioning use of these therapies between various care settings. A panel meeting was convened to provide literature- and experience-based recommendations in transitioning wound care patients between various care settings. The use of NPWT with instillation and dwell time was recommended in wounds contaminated with debris and/or infectious materials or heavy exudate. In addition, ORC/C/silver-ORC dressing application was recommended for surface bleeding and for placement into explored areas of undermining to help promote development of granulation tissue. When transitioning a patient from inpatient to outpatient care, overall health, access to services, severity and complexity of the wound, and equipment availability should be taken into consideration. Treatment modalities to bridge the gap during care transition should be used to help maintain continuous care. For outpatient care, NPWT use was recommended for removal of infectious materials and exudate management. The ORC/C/silver-ORC dressings also may be used to help manage exudate and promote granulation tissue development and moist wound healing. In addition, practice challenges and potential solutions for patient adherence, interrupted care during patient transition, and troubleshooting after hours and weekend device alarms were discussed.

OBJECTIVE: Healthcare systems are being challenged to manage increasing numbers of nonhealing wounds. Wound dressings are one of the first lines of defense in wound management, and numerous options exist. The oxidized regenerated cellulose (ORC)/collagen dressing may offer healthcare providers a robust and cost-effective tool for use in a variety of wounds. DESIGN: A multidisciplinary panel meeting was convened to discuss the use of ORC/collagen dressings in wound care and provide practice recommendations. A literature search was conducted to provide a brief review of the peer-reviewed studies published between January 2000 and March 2016 to inform the meeting. SETTING: A 2-day panel meeting convened in February 2017. PARTICIPANTS: Healthcare providers with experience using ORC/collagen dressings. This multidisciplinary panel of 15 experts in wound healing included podiatrists, wound care specialists (doctors, certified wound care nurses, and research scientists), and an orthopedist. RESULTS: The literature search identified 58 articles, a majority of which were low levels of evidence (69.3% were level 3 or lower). Panel members identified wound types, such as abrasions, burns, stalled wounds, diabetic foot ulcers, and pressure injuries, where ORC/collagen dressing use could be beneficial. Panel members then provided recommendations and technical pearls for the use of ORC/collagen dressings in practice. Barriers to ORC/collagen dressing use were discussed, and potential resolutions were offered. CONCLUSIONS: An ORC/collagen dressing can be a critical tool for clinicians to help manage a variety of wounds. Clinical and economic studies comparing standard-of-care dressings and plain collagen dressings to ORC/collagen dressings are needed.

Hyaluronic acid (HA), the main component of extracellular matrix, is considered one of the key players in the tissue regeneration process. It has been proven to modulate via specific HA receptors, inflammation, cellular migration, and angiogenesis, which are the main phases of wound healing. Studies have revealed that most HA properties depend on its molecular size. High molecular weight HA displays anti-inflammatory and immunosuppressive properties, whereas low molecular weight HA is a potent proinflammatory molecule. In this review, the authors summarize the role of HA polymers of different molecular weight in tissue regeneration and provide a short overview of main cellular receptors involved in HA signaling. In addition, the role of HA in 2 major steps of wound healing is examined: inflammation and the angiogenesis process. Finally, the antioxidative properties of HA are discussed and its possible clinical implication presented.

INTRODUCTION: Necrotizing fasciitis (NF) is a rare and rapidly progressing bacterial infection of soft tissues. Bacterial toxins cause local tissue damage and necrosis, as well as blunt immune system responses. A self-propagating cycle of bacterial invasion, toxin release and tissue destruction can continue until substantial amounts of tissue become necrotic. Neutralization of bacterial toxins should improve the results. MATERIALS AND METHODS: Pure hypochlorous acid (HOCl) (0.01% w/v) with no sodium hypochlorite impurity in saline pH 4-5, which was recently shown to both eradicate bacteria and neutralize bacterial toxins in vitro, was administered via flowthrough instillation to 6 patients with NF 4-6 times daily as needed. Utilizing a vacuum-assisted closure, 5-10 mL of pure 0.01% HOCl with no sodium hypochlorite impurity was instilled and removed frequently to irrigate the wounds. RESULTS: Of the 6 patients, no deaths or limb amputations occurred. All infected areas healed completely without major complications. CONCLUSION: The toxicity and immune dysfunction caused by bacterial toxins and toxins released from damaged cells may be mitigated by flow-through instillation with saline containing pure 0.01% HOCl with no sodium hypochlorite impurity. Randomized controlled clinical trial research of this relatively simple and inexpensive instillation protocol is suggested for identified cases of NF.
