Filter by:In patients on mechanical ventilation, it is not known whether the identification of S. aureus in LRT samples improves the performance of its nasal detection. To assess the MSSA or MRSA carrier status of patients requiring mechanical ventilation for more than 48 hours after major heart surgery: comparing the performance of the diagnostic technique Xpert® SA Nasal Complete assay in nasal swab and LRT samples.
During video-assisted thoracoscopic lobectomy (VATS), the surgeon inserts a small camera attached to a thoracoscope that puts the image onto a video screen. Instruments are inserted via small incisions, and the lung resection is completed. Robotic thoracic surgery (RTS) uses a similar minimally invasive approach, but the very precise instruments involved with RTS allow the surgeon to view the lung using 3-dimensional imaging. The instruments give the surgeons increased range of motion during the surgery, and research demonstrates that RTS has a less steep learning curve as compared to VATS. Both VATS and RTS demonstrated better results as compared to traditional thoracotomy (open surgery). However, Robotic lobectomy has not yet been compared directly to video-assisted thoracoscopic lobectomy (VATS) in a prospective manner. There are two major barriers against the widespread adoption of robotic thoracic surgery. The first barrier is the lack of high-quality prospective data. To our knowledge, there are no prospective trials comparing VATS to RTS for early stage lung cancer. The second major barrier to the widespread adoption of robotic technology in thoracic surgery is the perceived higher cost of Robotic lobectomy. To address these barriers, the investigators will undertake the first randomized controlled trial comparing Thoracoscopic Lobectomy to Robotic Lobectomy for early stage lung cancer. Prospective randomization will eliminate the biases of retrospective data and will serve to determine whether there exist any advantages to Health Related Quality of life (HRQOL) or patient outcomes in favour of Robotic Lobectomy over VATS Lobectomy. Furthermore, through a prospective cost-utility analysis, this trial will provide the highest quality data to evaluate the true economic impact of robotic technology in thoracic surgery in a Canadian health system.
Lung cancer is the leading cause of cancer deaths worldwide. However, if diagnosed at an early stage (tumor <2 cm), lung cancer is highly curable with a 5-year survival rate greater than 80% after surgical resection. Screening tests have made it easier to identify small lung tumors. However, these tumors are often not visible to the naked eye, and surgeons cannot feel them, making them difficult to precisely locate and remove. For this reason, surgeons have become more reliant on image guided surgery for the removal of these tumors. The standard of care for locating and removing small lung tumors is microcoil-guided video-assisted thoracoscopic surgery (VATS). This is a two-step procedure performed by two separate physicians. - First, patient is taken to radiology suite and radiologist inserts a microcoil near the lung tumor - Second (usually occurs a few hours later), patient is taken to operating room; a surgeon uses an x-ray arm to find the microcoil within the lung and remove it surgically. A pathologist reviews the resected tissue to make sure that the tumor and the microcoil were both removed. Until this evaluation, the surgeon does not know whether the tumor has been removed or not. While this method is safe, it is time consuming, uses staff resources, and requires bulky equipment to complete. In this study, we plan to develop and test a new method of identifying and removing small lung tumors. This procedure is called Electromagnetic Navigational Bronchoscopy (ENB) Robotic Indocyanine Green Guided Surgery (RIGGS) or ENB-RIGGS for a short name. The purpose of this study is to test the safety and reliability of the ENB-RIGGS surgery in the form of a pilot study. ENB-RIGGS surgery is done in the operating room by a surgeon under general anesthetic. ENB-RIGGS begins by creating a 3-D GPS map of the lung which guides the surgeon directly to the tumor. A fluorescent green dye called indocyanine green is then injected into the tumor, and when viewed by the special robotic camera the tumour will fluoresce with a green hue allowing the surgeon to easily see the tumour. The surgeon then uses the robot to remove the tumor and surrounding tissue. The lung tissue specimen will be evaluated immediately by a pathologist.
The aim of this study was to compare the functional capacity of exercise by six-minute walk test before and after thoracic surgical procedure in subjects who have undergone the Fast-track protocol with those who were under conventional care. Researchers want to find out if Fast-track is a strategy to enhance functional capacity after thoracic surgery.
Introduction: Pain is an important factor of increase of morbidity and mortality in patients undergoing surgical procedures include thoracotomy. There are different methods of analgesia in postoperative thoracic surgery, ranging from systemic analgesia with opioids, as well as local anesthetics block (intrapleural, extrapleural, intercostal cryoanalgesia, etc.) in addition to spinal blocks and Epidural blocks. In the pharmacological analgesia, electroanalgesia has been proposed as an adjunctive treatment for the relief of postoperative pain. Rationale: noting the lack of data in the literature regarding the use of this physical therapy technique in order to reduce the pain in the postoperative period of thoracic surgery and its consequences, it is relevant to the realization of a new randomized controlled trial (RCT) to evaluate the effects of transcutaneous electrical nerve (TENS) in the post - thoracic surgery on pain, pulmonary function and strength respiratory muscle. Objective: To evaluate the effects of TENS on pain, respiratory muscle strength and lung function in postoperative thoracic surgery in a Intensive Care Unit. Method: The subjects included will be randomized into three groups randomly: control group (CG) that will hold only conventional physical therapy, TENS group (EG) that will hold the application of TENS associated with conventional physical therapy, TENS placebo group (GP) who will perform the application of TENS placebo to conventional therapy. All groups carry out the assessments (digital manometer, spirometry, visual analog pain scale) in the preoperative period, postoperative Immediate / pre-intervention and at the end of treatment (discharge from the intensive care unit), except for the pain that will be evaluated before and after each intervention session. All patients receive physical therapy three times a day (morning, afternoon and evening) during hospitalization in the intensive care unit. Intervention: The conventional group will receive conventional therapy for hospital service. The TENS group will receive conventional therapy and the end of that service, will be applied TENS for 30 minutes. The placebo TENS group will receive the conventional physical therapy and the end of the service will be installed TENS placebo, during this period the patient receives electrical stimulation for 45 seconds, shutting down at the end of this time and held position as TENS group.
The study investigates inflammatory and antiinflammatory response in patients with severe aortic valve stenosis needing either surgical treatment (surgical aortic valve replacement) or interventional cardiology treatment (transcatheter aortic valve implantation using the transfemoral access route or the transapical access route).
Introduction: Compared with the Macintosh laryngoscopy (MAC), the videolaryngoscopes (VL) provide superior glottis views and longer times to double-lumen tube (DLT) intubation. We hypothesize that the use of the King Vision™ (KVL) and the Airtraq® VLs may reduce the time for DLT intubation compared with the Glidescope® (GVL) and MAC in patients undergoing thoracic procedures. Methods: One hundred-forty patients who will be scheduled for elective thoracic procedures using the DLT for one-lung ventilation will be randomly assigned to one of four groups (n=35 per group) to intubate using the MAC, GVL, Airtraq®, or KVL. Time to DLT intubation, glottis view, ease of intubation, number of optimization maneuvers, and failure to intubation (>150 s.) will be recorded.
There is clinical equipoise about the question of whether antibiotic prophylaxis should be given for a short period or an extended period of time as reflected by inconsistencies in major guidelines, current practices at Canadian centers, and as concluded in the three systematic reviews. There also is clinical equipoise on whether the addition of vancomycin to routine cefazolin prophylaxis can further reduce s-SSI rates. A short duration of combined antimicrobial prophylaxis can reduce side effects of exposure to antimicrobials such as infections with C. difficile or emergence of resistance, but may also reduce the incidence of s-SSIs. The objective of the eventual full scale study is to determine whether adding vancomycin to cefazolin can reduce SSIs as well as whether short-term prophylaxis is as effective as long-term prophylaxis. The rationale to conduct the proposed pilot study is to assess the feasibility to conduct this factorial cluster randomized cross-over trial, the adherence to the study protocol at each pilot site, the length of time to fill out the case report forms, and to get reliable estimates of event rates for sample size calculation for the main study
Post thoracotomy pain syndrome still affects 50% of patients after a thoracic surgery. Pathogenesis is unclear but there is growing evidence that neuro inflammation may play a significant role. Dexamethasone is a very potent anti-inflammatory drug. The hypothesis of this study is that dexamethasone, given pre operatively, would help reduce the incidence of post thoracotomy pain syndrome 3 months after surgery, by reducing the inflammatory response, in patients undergoing elective thoracic surgery that includes thoracic epidural analgesia.
The purpose of this pilot study is to determine the feasibility of comparing colchicine to placebo for the prevention of new onset atrial fibrillation in patients undergoing general thoracic surgery and establish the foundation for a large, multi-centre, clinical trial.
