Filter by:The purpose of this research study is to investigate if a new negative pressure incision (surgical cut) management system, could reduce the occurrence of groin wound infections after vascular surgery. This is a single use, sterile dressing that is applied to the patient's skin. It has an attached battery-powered unit that provides negative pressure (a vacuum environment) to the dressing and a disposable canister for the collection of wound fluids. The patient is being asked to participate in this study because the patient is planning to have a vascular surgery procedure that involves groin incision.
Aspiration of gastric content is a rare but serious complication of anesthesia. In this context, preoperative fasting for elective surgery is well defined. In an emergency situation, international guidelines recommend rapid sequence of anesthesia to reduce the risk of aspiration. In semi emergency situation, there is no consensus about the anesthetic procedure even if a preoperative fasting has been observed due to uncertainty of gastric emptying related to stress or painful condition. The choice of anesthesia induction technique depends mainly on the anesthetist. Ultrasonography is a non invasive bedside tool that can provide reliable quantitative information about the volume of gastric content.
The investigators are studying ways to improve pain control after surgery. One way to decrease pain is to inject incisions with a numbing medicine (local anesthetic) while in the operating room. There is an FDA approved extended-release version of a commonly used local anesthetic (bupivacaine) that can last for 4 days instead of 6 hours. The investigators are studying whether using the extended-release medication (Exparel) will give better pain relief after laparoscopic and robotic-assisted hysterectomies.
The goal of this clinical research study is to learn more about the safety and feasibility of using the Da Vinci Robotic Surgical system in procedures that harvest the latissimus dorsi muscle (a back muscle below your shoulder) for reconstructive procedures.
The lung expansion techniques are widely used to prevent postoperative pulmonary complications. However, the effect of each technique on thoracoabdominal mechanics after abdominal surgery and if it influences the rate of postoperative pulmonary complications remains unknown. The investigators hypothesis is that the lung expansion technique that more increases lung volume after abdominal surgery, will be the most efficient in preventing postoperative pulmonary complication after abdominal surgery. The investigators objectives will be to compare the effect of different lung expansion techniques on lung volumes and activation of inspiratory muscle, and prevention of pulmonary complications in patients undergoing upper abdominal surgery. This study will involve 171 patients undergoing elective abdominal surgery. Patients will be randomly divided into 5 groups: no therapy group (n=35), continuous positive airway pressure (CPAP, n=34); volumetric incentive spirometry (VIS, n=34); flow oriented incentive spirometry (FIS, n=33) and deep breathing (DB, n=35). The thoracoabdominal mechanics will be assessed before and 3 days after surgery. Complications will be evaluated by a researcher who did not know to which group each patient belongs.
The purpose of this study is to demonstrate that using Surgical Pleth Index (SPI) and Entropy in adjunct to other clinical information decreases the occurrence rate of inadequate anesthesia events, bradycardia and hypotension in comparison to standard clinical practice during anesthesia. Adequacy of Anesthesia (AoA) monitoring comprises the use of both Entropy and SPI measurements. Adequacy of anesthesia will be monitored using non-invasive blood pressure, blood oxygen saturation (SpO2), ECG, and neuromuscular transmission (NMT).
Objectives: The aims of this study are (1) to define the effectiveness of functional nasal surgery during Le Fort I osteotomy on nasal obstruction through objective as well as subjective evaluations, (2) to determine guideline for concomitant functional nasal surgery with Le Fort I osteotomy, and (3) to explore possible mechanisms by which functional nasal surgery may reduce nasal obstruction severity. Design: A prospective, single-blnd, randomized trial. Setting: Chang Gung Craniofacial Center and Department of Otolaryngology (ENT). Patients: A total of 80 Taiwanese patients with unilateral cleft lip and palate and dentofacial deformity (age >16 for females, >18 for males; 40 in experimental and 40 in control groups) Interventions: In the experimental group, all patients will receive Le Fort I osteotomy and septoplasty. In the control group, all patients will receive Le Fort I osteotomy only. Measurements: All patients will undergo history taking, clinical examination, radioallergosorbent (RAST) examination (before surgery), standard questionnaire and image examination before surgery, one week, 1, 3, 6, 12 and 24 months after surgery. To reduce radiation exposure, cone-beam CT will only be performed before surgery and one week, 12 and 24 months after surgery. Data Analysis: Independent t and chi-squared tests, correlation coefficients and repeated measures analysis of variance (ANOVA) will be used. Statistical significance is assumed for a p value of less than 0.05. Key Words: cleft lip palate, nasal septum deviation, Le Fort I osteotomy, septoplasty, effectiveness
Nasal irrigation techniques have been used for many years and been shown to improve symptoms of rhinosinusitis. Although there is a wealth of literature available, establishing treatment protocols can be difficult because of the great variability in recommended composition (seawater or hypertonic or isotonic saline with or without additives) and irrigation technique (variations in pressure and volume). Nasal irrigation is also used in many centers as part of postoperative treatment protocols and in particular has been recommended following endoscopic sinus surgery (ESS). Nasal crusting and thick nasal discharge have a negative impact on these patients quality of life (QOL). At the time of our study, there are no studies comparing irrigation with mucolysis with saline irrigation following ESS. The investigators aimed to assess whether mucolysis is effective at improving patients QOL and reducing postoperative signs as assessed endoscopically.
Evaluation of Safety and Efficacy of ViKY Device for Uterus Positioning on 2 US sites
The investigators propose to conduct formative research to gain an understanding of patients' needs and desires regarding elective Bilateral Salpingo-Oophorectomy (BSO) decision making, and to develop and pilot test a BSO Decision Support Guide, in preparation for a randomized, controlled trial of the effect of this decision aid on decision quality and use of BSO. The proposed study will consist of 3 phases. In phase 1, the investigators plan to conduct focus groups among women who have had a hysterectomy with or without bilateral salpingo-oophorectomy (BSO) to gain an understanding of what they understood about BSO and its possible outcomes at the time of their hysterectomy and what they would have liked to have known, the extent and manner in which they were included in decision making regarding BSO, and how they feel about the decision now. The investigators also will collect qualitative data from women who are scheduled for hysterectomy and currently facing the decision whether or not to undergo elective BSO. In phase 2, the investigators plan to create a BSO Decision Support Guide using information obtained from the literature, from our formative research, and the experience of providers who have counseled women about this choice. In phase 3, the investigators plan to pilot test the BSO Decision Support Guide among women scheduled to undergo hysterectomy for benign conditions to assess its usefulness and usability for patients and their providers and to prepare for a randomized study of its impact on decision quality and use of BSO. 62 women who are scheduled to undergo hysterectomy for a non-cancerous uterine condition will participate in the pilot study. These women will participate in a baseline interview, during which they will be provided access to the BSO Decision Support Guide, and 2 follow up telephone interviews (one as they are making their final BSO decision and a second after they have undergone and recovered from their hysterectomy (with or without BSO). Data will be used to generate the final version of the Decision Support Guide, to finalize evaluation measures for future studies of the effectiveness of the guide, and to determine effect sizes for the outcomes of knowledge, BSO use, decision satisfaction and decisional conflict.
