The Closer Trial: A Safety and Efficacy Study of the Rex Medical Vascular Sealing System
Surgical WoundThe objective of this trial is to demonstrate the safety and effectiveness of the Rex Medical Closer Vascular Sealing System in sealing femoral arterial access sites.
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.
Blood Characteristics and Abdominal Emergency Surgery
Surgical WoundAfter surgical tissue damage, cellular blood components are involved in tissue repair processes, yet their preoperative characteristics are not considered in routine clinical practice.
Use of Prineo in Breast Reduction Surgery
Efficiency of Surgical Incision ClosurePost-operative ScarThis is a prospective, randomized, controlled, single-blinded study to compare Prineo™ with subcuticular sutures in 20 women undergoing bilateral breast reduction. For each patient, the final skin layer of one breast will be closed with subcuticular suture while the other breast will be closed with Prineo™. The treatment will be randomized to left or right breast. Therefore, the investigators will have 20 breasts in the suture group and 20 in the Prineo™ group, with each patient serving as her own control. For this study, the resident will close one side with suture and Dr. Rohde will apply the Prineo. The investigators will perform this study of incision closure under conditions as similar to normal conditions of closure.
Duration of Postoperative Antibiotic Prophylaxis in Facial Fractures
Surgical Wound InfectionFacial fractures make up a significant proportion of injuries in trauma patients. Treatment of these fractures often results in standard surgical interventions. While up to the early 1980's perioperative antibiotic prophylaxis in maxillofacial surgery was controversial, its efficacy is well accepted today. Chole and his team could show that the administration of antibiotics one hour preoperatively and eight hours after the intervention reduces the incidence of infectious complications in facial fractures from 42,2% to 8.9%. However there is still no consensus about the duration of the postoperative administration. In literature postoperative prophylaxis in facial fractures varies from single-shot 6-7 up to a duration of 7 and even ten days postoperatively 8-10. The use of antibiotics can be associated with allergic or toxic reactions, adverse effects, drug interactions and increasing bacterial resistance. In addition some authors assume that a prolonged administration of antibiotics might increase the risk of infectious complications via superinfection. On the other hand a short term or single shot administration might not be enough to prevent the onset of an postoperative infection. Up to date there is no standard to support the administration of antibiotics after surgical repair of a facial fracture. The purpose of this prospective, randomized double-blinded trial is to investigate the utility of antibiotics administered in the postoperative period after surgical revision of facial fractures. Hypothesis: a short-term antibiotic prophylaxis of 1 day postoperatively is equally effective as a long-term administration of 5 days in facial fractures.
Evaluation of the Levels of Pain and Discomfort Between Two Methods of Correcting Misaligned Teeth...
MalocclusionCrowded Teeth1 moreApplying flapless piezocision corticotomies on the alveolar bone and separating anterior mandibular teeth using a piezosurgery device (i.e. ultrasonic waves that perform very accurate incisions without any sutures following this procedure) may improve the speed of tooth alignment during orthodontic treatment. This study consists of two groups, patients will be randomly assigned to one of these two groups. The levels of pain and discomfort of this procedure on 18 patients (experimental group) will be evaluated,whereas the second group (control group) will receive a traditional orthodontic therapy.

Surgical IncisionMalocclusionApplying flapless piezocision corticotomies on the alveolar bone and separating anterior mandibular teeth using a piezosurgery device (i.e. ultrasonic waves that perform very accurate incisions without any sutures following this procedure) may improve the speed of tooth alignment during orthodontic treatment. This study consists of two groups, patients will be randomly assigned to one of these two groups. The efficacy of this procedure on 18 patients (experimental group) will be evaluated,whereas the second group (control group) will receive a traditional orthodontic therapy. The time required to achieve complete alignment of crowded mandibular anterior teeth (from canine to canine) will be compared between the two groups.
Transversus Thoracis Muscle Plane Block for Sternotomy Pain in Cardiac Surgery
PainPostoperative2 moreSternotomy pain is usually significant after cardiac surgery. Analgesic options for sternotomy in cardiac surgery are often limited. Poorly controlled acute pain is an important factor to development of chronic postsurgical pain. The transversus thoracis muscle plane (TTP) block is a novel technique that provides analgesia to anterior chest wall. A double-blinded RCT is conducted to assess the efficacy of applying TTP block as an adjunct to analgesia in cardiac surgery.
Clinical Trial of MedLogic LiquiBand Laparoscopic Versus Dermabond in the Closure of Surgical Incisions...
Laparoscopic SurgeryTo evaluate the effectiveness, safety, and utility of LiquiBand Laparoscopic™ in relation to a currently approved active control product (High Viscosity DermaBond). Specifically, the study is powered to demonstrate that LiquiBand Laparoscopic™ is not inferior to DermaBond in the rates of infection, dehiscence, cosmesis and apposition of the skin.
The Effects of Stress Reduction on Surgical Wound Healing
Wound HealingStress1 moreThe purpose of this study is to investigate whether a stress reduction intervention prior to surgery can improve wound healing and recovery.The investigators hypothesise that patients who receive a psychological stress reduction intervention prior to surgery will report lower stress and higher perceived control, have lower stress hormones, better wound healing and better self-reported recovery than patients who receive standard care alone.
