Filter by:This study is designed to demonstrate the outcome of complete ulcer closure of patients with Wagner Grade 1-4 DFUs, VLUs or Stage II-IV PUs using AutoloGel versus Usual and Customary Care (UCC).
The purpose of this study was to determine which of three types of dressings, a dry sterile dressing, a metallic silver dressing or an ionic silver dressing provided better patient outcomes for the post-sternotomy cardiac surgery patient population. In this prospective, randomized controlled trial, the hypothesis was that subjects who received either of the silver impregnated dressings would have better outcomes (better wound healing, less discomfort, and less incidence of infection). Investigators also evaluated dressing factors such as adherence, time for application and ease of use.
Epidermal grafts are believed to promote healing by two mechanisms: graft take and the promotion of wound healing through the delivery of growth factors and the essential elements of tissue repair and wound healing.28 This study is intended to establish the superior effectiveness of epidermal grafting and multi-layer compression over that of multi-layer compression alone, in the treatment of venous leg ulcers. Millions of Americans are afflicted with painful, open, draining sores on their lower extremities. These sores are referred to as venous leg ulcerations (VLUs). Under the best of circumstances these ulcers require weeks or months to heal. Not uncommonly wound care specialists see patients who have suffered for years or faced amputation of the limb as their only option to alleviate the pain. Standard of care will result in healing in 50% of venous leg ulcers in 12 weeks. However, roughly half of patients suffering from venous ulcers will require advanced therapy. Epidermal grafting has been a reconstructive option for decades; however, to date there has not been a reliable and reproducible system to harvest epidermis. The CelluTome® Harvesting System permits the harvesting of epidermal blister grafts at the patient's bedside without the need for anesthesia. The grafts can be easily transferred to the wound bed. In case studies, epidermal grafting appeared to be effective in reducing wound size and accelerating closure of venous leg ulcers.
A split-thickness skin graft (STSG) is used for a large wounds or wounds that cannot be closed by primary and secondary wound closure. Accelerated re-epithelialization rate and minimizing pain and infection are main goals of donor care. Traditionally dressings are inexpensive but adhere to the wound surface and cannot absorb exudates. Thus, we have developed a new biomaterial based on Thai silk for wound dressing application. Silk fibroin and silk sericin were selected to produce wound dressing in this study. The objective of this study is to compare wound dressing containing silk fibroin with bioactive coating layer with standard dressing (medicated paraffin gauze dressing; Bactigras®), with regard to healing time, patients' pain intensity, skin's transepidermal water loss after healing and evidence of infection in the treatment of split-thickness skin graft donor sites. The study design is a randomized, controlled, self paired clinical trial. Patients age 18 to 60 years and undergo STSG at thigh in Department of Surgery, King Chulalongkorn Memorial Hospital will be recruited in the study. The exclusion criteria are donor sites other than thigh area or located at high risk of infection. Patients who are immunocompromised or diabetes mellitus or psychiatric disorders or low serum albumin level (less than 3.0 g/dL) or known allergic to SS or SF or paraffin or chlorhexidine acetate are also excluded. All subjects sign the informed consents after discussion the protocol, benefits and risks. The donor site will be divided into two equal halves, each site will be randomized to receive the tested material or the medicated paraffin gauze dressing. The donor site wounds will be observed daily. The dressings will not be changed, except when they are fully soaked with exudates and easily fell off or any sign of infection. Healing time will be recorded when the dressing separate completely from the donor site, no exudates and no pain when the donor site is exposed to air. The patient's pain level will be evaluated with the visual analogue scale and the donor site wounds will be observed daily for signs of infection. On the day of the wound is recorded for healing time and 1 weeks, 1, 2, 3, 4 and 5 months after that, the skin barrier function (TEWL) of each site will be measured using a Tewameter. Blood sample will be collected from patients pre- and postoperatively (within day 3) for hepatic and renal function analysis.
1. Silk sericin wound dressing may reduce time for complete epithelialisation of split-thickness skin graft donor sites compared to Bactigras®. 2. Silk sericin wound dressing may reduce pain level at split-thickness skin graft donor sites compared to Bactigras® . 3. Silk sericin wound dressing may not cause split-thickness skin graft donor sites infection as compared to Bactigras®. 4. Split-thickness skin graft donor sites which treat by silk sericin wound dressing may not cause significant adverse events.
This clinical study is performed in several German, Dutch and Belgian hospitals to evaluate the efficacy of Vacuum Assisted Closure® (V.A.C.®) for the treatment of postsurgical abdominal wound healing impairments after surgery. Therefore the underlying layer of fibrous tissue that permeates the internal organs must be intact. Main outcome measure is the time until complete wound closure that sustained for a minimum of 14 days. Furthermore the therapy options will be examined regarding several other clinical, safety, patient reported and economic parameters. Patients will be assigned equally and by chance to both treatment groups. Study participants as well as the attending doctors and nurses will be informed about the assignment to the respective treatment arm. The primary outcome measure and some of the secondary parameters like reappearance of the wound and the development of the wound size over time, examined within an active study treatment time of 42 days, will be photographed and analysed under the use of a central computer system. The central analysing personal will not be informed about patient details or therapy allocation. Patients with at first closed belly wounds with wound healing disorder in the postoperative course after surgery without an opening of the underlying layer of fibrous tissue are eligible to be included in the trial if the diagnosis of a wound healing impairment in the postoperative course is manifested as a wound with spontaneous dehiscence, a wound that requires an active reopening of the suture by the treating physician or a wound that cannot be closed by primary intention and requires further treatment to achieve permanent closure. Study participants will be selected and enrolled within clinical surgical departments which provide the respective personal, structural and scientific background for the conduction of the trial project. Trial therapy will be started in-hospital and may be continued in ambulatory care. It is very important to examine the therapy options also in the ambulant care setting thus study participants with good health who are able to continue the specific wound treatment in ambulant should be transferred to the ambulant service as soon as possible.
This study evaluates a novel micrografting technique to see how it will influence the healing rate and cosmetic result of second intention wounds. The graft harvesting and micrografting process was designed by MoMelan Technologies The Epidermal Expansion System, which is composed of a commercially available Blister Generation Device and the Microblister Generation and Excision Device (MBGED), will generate an array of small microblisters and transfer the micrografts to a sterile dressing (Tegaderm™ - an FDA approved wound dressing) for application to the subject's surgical area. The investigators predict that applying expanded micrografts to wounds that otherwise would have healed by second intention alone will hasten healing and possible reduce scarring.
This observational study aims to identify risk factors and molecular mechanisms of impaired wound healing, to guide better foot care in the diabetic population.
This clinical observational study investigates the incidence of wound healing abnormalities in patients undergoing major abdominal surgery. Second aim of the study is, if wound healing deficits may be accompanied by abnormalities in blood coagulation parameters.
A study to compare the rate of complete wound closure and quality of resulting scar at 3, 6 and 9 months, between dermatome-induced skin wounds treated with Collagenase Santyl Ointment versus vehicle alone.
