Early Versus Delayed Bathing of Orthopaedic Surgical Wounds

This is a single center randomized control trial assessing the effect of early versus delayed bathing on orthopaedic surgical wounds in patients undergoing surgical treatment of fractures. Patients will be recruited by screening all patients undergoing surgical treatment for fractures at our institution. Patients who provide written consent will be randomized to one of two treatment arms after confirming eligibility criteria. Group A will be advised to begin early normal bathing (non-submerged showering) with uncovered surgical wounds. Group B will be advised to follow traditional delayed bathing with covered wounds. Those who do not wish to participate in the randomized trial will be invited to participate observationally (no randomization) and have the same prospective follow-up.

Influence of Sun Protection and Linear Repair of Cutaneous Surgical Defects

The purpose of this study is to determine the potential influence of sun protection on the aesthetic outcome of post-surgical scars following the reconstruction of Mohs micrographic surgery defects via linear repair. This study will be performed as a randomized split-wound study. Half of the wound will be treated with zinc containing sunscreen and the other half of the wound would not be treated. Three-months post-surgery, the scar will be evaluated via the patient observer scar assessment scale (POSAS), a validated scar instrument, as well as a colorimeter to measure the amount of vascularity, and hyperpigmentation between the treated and the non-treated area compared to the 'surrounding skin' defined as skin in the proximity but not adjacent to the wound. Any adverse events will also be recorded.

Evaluating rhPDGF-BB-Enhanced Wound Matrix for Head and Neck Reconstruction

Skin cancers such as basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma lesions that develop on the head and neck are treated by Mohs surgery or wide local excision to remove all tumor cells and preserve the normal tissue. These surgical techniques may result in large defects requiring reconstruction to restore function and aesthetics. Rotational flaps and free flaps are techniques used to reconstruct large, complex defects that cannot be closed with sutures, staples, or glue. Older, frail patients are particularly vulnerable to complications from these procedures often leaving them to care for chronic wounds until a skin graft can be placed. Phenome-wide association studies (PheWAS) revealed a cohort of patients with a single nucleotide variant (SNV) in PDGFRβ having a higher incidence of chronic skin ulcers, skin grafts, and other skin and connective tissue disorders suggesting that the loss of PDGFβ signaling may impair healing following trauma. rhPDGF-BB, a recombinant human platelet derived growth factor protein-based therapy, signals through PDGFRβ to mediate inflammation, granulation, angiogenesis, and remodeling during wound healing and skin repair and is FDA cleared for diabetic neuropathic ulcers and periodontal bone and soft tissue reconstructions. These data suggest rhPDGF-BB may be a viable therapeutic strategy to augment the reconstruction of these complex defects by accelerating granulation, epithelialization, and wound closure.

Randomized Controlled Trial to Investigate Clinical Outcomes and Associated Costs When PermeaDerm is Used as Temporary Dressing for Surgical Wounds

The goal of this study is to compare the cost and clinical outcomes for two temporary dressings (Allograft and PermeaDerm) used in patients that need a skin graft to heal their wound. The researchers will review cost and other treatment results including how well both temporary dressings attach to the skin, how prepared the wound bed is to receive a skin graft, how long it takes for the skin to be ready to receive a skin graft, how well the skin graft takes and any complications. Patients will first have the temporary dressing applied to their wound, then a few days later, a skin graft will be performed. Patients will have photos of their wounds taken throughout the study including at all the clinic check-ups with the last check-up occurring about 8 weeks after treatment.

CO2Lift and T-Junction Breakdown Rates Evaluation After Breast Reduction Surgery Pilot Trial

The goal of this pilot study is to determine the feasibility of a larger randomized controlled trial evaluating CO₂Lift® Pro Carboxy Gel to reduce wound breakdown after bilateral breast reduction in adult female patients undergoing elective bilateral breast reduction surgery. The main question it aims to answer is: Is it feasible to recruit, retain, and treat patients while maintaining blinding and monitoring safety? Exploratory questions include: (1) Does CO₂Lift® reduce the incidence of wound breakdown compared with placebo? (2) Is CO₂Lift® safe and well-tolerated in the postoperative period? Researchers will compare CO₂Lift® applied to one breast to placebo (Vaseline®) applied to the contralateral breast to see if CO₂Lift® can improve wound healing and tissue oxygenation. Participants will: * Undergo bilateral breast reduction surgery. * Receive CO₂Lift® on one breast and placebo on the other, starting immediately after surgery and daily in clinic from postoperative days 1 to 6. * Attend weekly postoperative follow-up visits for 12 weeks for wound assessment and monitoring of adverse events. * Have standardized photographs and near-infrared spectroscopy measurements taken to evaluate tissue oxygenation and healing.

Strip Graft w/ Xenogeneic Matrix vs Free Gingival Graft for the Augmentation of Peri-implant Keratinized Mucosa

Suture Closure Trial

Closure of surgical incisions in orthopedic procedures contributes to patient postoperative pain and risk of complication. As the focus on improving orthopedic surgery outcomes shifts to best practices in postoperative pain management, it is important to consider suture types and techniques. This study specifically would focus on comparing different suture types and techniques and their efficacy. This will be a randomized controlled trial comparing currently used, standard of care suture types and currently used, standard of care suture techniques to identify differences, if any exist, in postoperative pain scores and wound healing as assessed by exam and postoperative patient surveys. Patients will be identified by the Emory Upper Extremity/Hand Surgeons as they are identified as a candidate for surgery. Participants will then be informed of the study and spoken to about the specifics of the study. The research team will consent and recruit patients either in The Emory Clinic or in the preoperative area prior to surgery. All surgical operations will take place at the ambulatory surgical center in The Emory Clinic or at the Emory University Orthopaedic and Spine Hospital. Patients will not be compensated for participation in this study. No specimens/data/samples will be collected and stored for later use, and there are no optional substudies. This proposed study will address the lack of published literature regarding the suture technique in hand and wrist surgery in particular. Combined with examining various suture materials, the proposal has the potential to provide a valuable and actionable base of knowledge to the current body of literature.

Does photobiomodulation reduce pain in palate donor sites, improving the quality of life? Participants who need gingival graft surgeries will receive laser irradiation on the palate donor area or just protection with wound dressing. Data will be collected up to 60 days. Researchers will compare protection on the palate and protection plus laser irradiation to see if laser therapy may reduce pain and accelerate somatosensory normalization. Moreover, they will measure changes in the quality of life after treatment.

Virtual Reality Glasses and Stress Ball Applications in Dressing Change

According to the statistical data of the Ministry of Health for the year 2021 in Türkiye, approximately 4.7 million surgical interventions are performed annually. According to the 2017 data from the National Health Service-Associated Infections Surveillance Network, the Surgical Site Infection (SSI) rate in our country is 0.72%, and it is stated that it can be prevented by approximately 60%. Dressing application holds an important place in surgical wound management, wound healing, and preventing complications. Patients may experience pain, anxiety, and fear due to unknown factors and previous experiences during the dressing change which holds an important place in wound care management. The aim is to minimize patients\&#39; negative emotions/situations during dressing changes by diverting their attention elsewhere using virtual reality (VR) glasses and stress balls. Upon reviewing the literature, no study was found that examines the effect of applying VR glasses and stress balls during abdominal surgery dressing changes on pain, vital signs, anxiety, fear, comfort, and satisfaction levels in adults. In this regard, the aim of the research is; to examine the effects of VR glasses and stress ball application on pain, vital signs, anxiety, fear, comfort, and satisfaction levels during dressing changes in patients undergoing abdominal surgery. The study was designed as a pre-test post-test control group randomized experimental model. The sample of the study consists of adult patients who underwent abdominal surgery in Isparta City Hospital General Surgery Service-1. In the study sample, 120 individuals were included in total 40 with VR glasses, 40 individuals using stress balls, and 40 in the control group. Patient Information Form, Visual Analog Scale, and State-Trait Anxiety Scale will be used in data collection. Data from the study will be analyzed with number, percent, average, x-square, variance, and t-test in a computer environment. In consideration of the data, it is believed that important findings will be obtained in increasing satisfaction and comfort by eliminating pain, anxiety, and fear during dressing changes in patients.
