Application of Indocyanine Green Angiography for Closed Operative Calcaneus Fractures
FracturesComminuted2 moreResearchers in the Orthopaedic surgery department at LSU Medical Center-Shreveport hope to learn if patterns of blood-flow around the incision site of patients undergoing surgery for heel-bone fractures can help predict whether complications will arise after a specific type of operation.The goals of this research study are to effectively answer as many of the following research questions as possible: Can a drug normally used to evaluate adequate blood flow in plastic surgery and tissue transfer be used to identify altered patterns of blood flow at the operative site of Calcaneus fractures, when compared to the uninjured extremity? Are changes in blood flow identifiable at the operative site post operatively? Are there certain patterns of blood flow present preoperatively or postoperatively that can predict wound complication? Can certain patterns of blood flow predict the location of slough or dehiscence after surgery? Does the incision site and its proximity to specific patterns of blood flow possibly predict wound complication? The hypothesis is that the study drug will show a correlation between certain patterns of blood flow and whatever post-operative complications may arise.
Trial of Versajet Compared With Conventional Treatment in Acute and Chronic Wounds
Surgical Wound DehiscenceIt is increasingly recognised that the debridement of devitalised, bacterially contaminated or senescent tissue is an essential component of the effective treatment of delayed healing wounds. Whilst surgical debridement procedures have conventionally been performed with scalpels and other sharp instrumentation, alternative techniques such as the VERSAJET Hydrosurgery System are becoming more widespread. To increase the adoption of this new technology, it is essential that clinical improvements are assessed alongside the potential impact on the costs of debridement and the net financial impact on the hospital. It is hypothesised that a decrease in the time to achieve stable wound closure will not only lead to a patient benefit, but also a potential reduction in the cost of treatment due to e.g. repeat procedures, longer hospital stay, infection etc. The purpose of this study is to investigate the difference in time to closure of wounds surgically excised with VERSAJET Hydrosurgery System and those surgically excised using conventional operating room techniques.
Three-dimensional Bone Regeneration Using Custom-made Meshes With and Without Collagen Membrane...
Surgical ProcedureUnspecified4 moreThe presence of alveolar ridge deficiencies is considered major limitation to achieve an implant-prosthetic restoration with high aesthetics and stability over time. Guided Bone Regeneration (GBR) can be considered an effective solution for bone augmentation. The most advanced technology of GBR is the customized titanium mesh, which is developed with a fully digital work flow system. The aim of this study is to evaluate complications and bone augmentation rates after GBR, based on customized meshes with or without collagen membranes. After ethical committee approval, 30 patients with horizontal and/or vertical bone defects were enrolled and treated according to the study protocol. During reconstructive surgery (T0), patients were randomly divided into two study groups: 15 patients were treated by means of a custom-made mesh without collagen membrane (Group A - Control Group), while 15 patients were treated by means of a custom-made titanium mesh with a collagen membrane (Group B - Test Group). All sites were grafted with a mixture 50:50 of autogenous bone and xenograft and primary closures of surgical sites were obtained to ensure a submerged healing of the meshes. After 6 months (T1), re-entry surgery was completed to remove the meshes, evaluate the augmented volume and to place implants in the augmented sites. After 3 months (T2), soft tissue management was accomplished with implant exposure and a connective tissue graft, before prosthetic restoration (T3). Data collection included surgical and healing complications, planned bone volume (PBV) and reconstructed bone volume (RBV), pseudo-periosteum type, bone density, implant success, and crestal bone loss. A statistical analysis of recorded data was performed to investigate any statistically significant differences between the study group and statistical significance was set at a=0.05.
Acupuncture and Post-Surgical Wound Healing
Postoperative ComplicationsSurgical Wound Infection1 moreThe purpose of this study is to determine if acupuncture improves wound healing. Since we, the investigators at the University of California, San Francisco (UCSF), know that how much oxygen is delivered to tissue is the best predictor of how well a wound will heal, we are measuring changes in tissue oxygen of wounds before and after acupuncture treatments. We are focusing on the leg wounds of coronary artery bypass graft (CABG) patients who have their saphenous veins harvested in an open fashion since this is a fairly well controlled patient model.

Blu Light for Ulcers Reduction
Leg Ulcers VenousDehiscence1 moreMulti-center study on the effectiveness of treatment with a blue light medical device (EmoLED) in the reduction of ulcer surface in 10 weeks. The aim of BLUR clinical trial is to verify if the proposed treatment represents a valid and significant remedy for Chronic Venous Insufficiency ulcers. The effectiveness will be measured through the evaluation of the reduction percentage of the lesion area during 10 weeks of treatment comparing the lesion (or portion of it) treated with EmoLED versus the control lesion (or portion of it) treated only according to current Standards of Care(SOC). In the 10 weeks following the recruitment, the patient continues to follow the usual topical therapy with a frequency of once a week visit. The patient will be monitored up to the first event occurring: Complete healing or ten weeks. During the study, reports and evaluations will be made by medical staff on the device safety and usability. 90 patients will be recruited corresponding to the following criteria: Subjects suffering from venous, arterial and mixed skin ulcers and surgical dehiscence lesions; Presence of similar multiple lesions or lesions larger than 5 cm ; Men and women ≥ 18 years old; The patient must be able to understand the aims of the clinical study and provide informed consent in writing; Chronicity of the lesion: at least 8 weeks. The present clinical trial will be a multi-center prospective, controlled study with the aim of verifying the clinical efficacy of a portable battery-powered device based on blue LEDs. We expect to record at least 20% of the difference between treated lesion and untreated lesion on the same patient during observation time. The treatment, additional to the standard therapy for the patient, will be performed at each visit for 60 seconds on each 5 cm diameter sub-area of the selected lesion or on part of it. In case of multiple lesions, one will be treated with EmoLED and one will be selected as a control lesion. In case of a very extensive lesion, it will be divided into two and one half will be the control of the other. All lesions will be cleansed with saline solution and a surgical debridement will be performed with a scalpel if a slough/black base is present. Only then the treatment with EmoLED will begin. If the patient has more than one lesion at the recruitment time, and all lesions are less than 5 cm in diameter, the worst lesions will be treated entirely with the EmoLED device and the others will constitute the control lesions. The evolution of all lesions in the ten weeks of the study duration will be evaluated. If the patient has only one lesion greater than 5 cm in diameter at the recruitment time, the lesion will be divided into two parts along the major side and one half of the lesion area will be treated. The other half of the lesion will be masked with multi-layered sterile gauze during treatment. The point of division of the lesion into two parts will be indicated with an indelible marker and retouched at each visit. If, at the time of recruitment, the patient has more than one lesion with a diameter greater than 5 cm, all lesions will be divided into two along the major side and will be treated as in the previous case. After treatment with EmoLED, a hydrofiber dressing will be applied to the lesion. If clinical signs of infection occur, a hydrofiber dressing with silver will be applied. If necessary, compressive bandage of the limb will be carried out.
Prophylactic Negative Pressure Wound Therapy for High Risk Laparotomy Wounds. A Randomized Prospective...
Surgical WoundWound Dehiscence3 moreNegative pressure wound closure technique (NPWT) has been widely introduced in different clinical settings. Most of the studies report it as an effective and cost-effective method to treat complicated surgical wounds or even open abdomen. NPWT as a prophylactic effort to prevent complications of high risk surgical wounds has recently been introduced, but the concept is still lacking clinical evidence in terms of clinical effectiveness and cost effectiveness. In this randomized, multi centric study investigators aim to compare prophylactic negative pressure wound closure (ciNPWT) with traditional, dry wound dressing at high infection risk laparotomy wounds.
Antimicrobial Dressing Versus Standard Dressing in Obese Women Undergoing Cesarean Delivery
Cesarean Section ComplicationsWound Breakdown3 moreThis will be an open label pilot randomized controlled clinical trial. Women undergoing cesarean delivery will be randomized to have standard wound dressing care or chlorohexidine gluconate (CHG) impregnated wound dressing (ReliaTect™ Post-Op Dressing).
Prevention of Fascial Dehiscence With Prophylactic Onlay Mesh in Emergency Laparotomies
Surgical Wound DehiscenceFacial dehiscence elicit high morbidity and mortality. This complication may arise in more than 8.5% of high-risk patients. Addressing risk factors and optimizing surgical technique are guarded as mainstay measures for prevention, but their efficacy is questionable. The aim of this study is to analyze the influence of using a polypropylene onlay prophylactic mesh on the incidence of fascial dehiscence in emergency surgery and associated complications.
Prevention of Wound Complications After Cesarean Delivery in Obese Women Utilizing Negative Pressure...
Surgical Wound DehiscenceWound InfectionWound complications after Cesarean section (C-section) are common in obese women. Approximately 25% of obese women having a C-section will have a wound complication. This research study is designed to assess whether applying a source of vacuum (suction) to the wound can reduce the risk of wound complications. The investigators plan to enroll 220 women into the study. Women will be randomly selected to receive standard stitching and stapling of the incision (cut on the abdomen) or closure with stitches, staples and wound suction. Subjects will be seen for follow-up visits in 7-14 days and again at 4-6 weeks after surgery. The number of wound complications in each group will be compared. If the wound suction technique is successful in preventing wound complications, this may substantially reduce pain and suffering in a large number of women undergoing C-section for delivery.
