Filter by:The purpose of this study is to evaluate the postoperative pain and discomfort using flurbiprofen axetil or nalbuphine administration after oculoplastic surgery under general anesthesia.
The investigators will use multilevel multivariable regression analysis to measure the association of sex with provision of guideline-based perioperative care for hip fracture surgery in Ontario.
Natural killer (NK) cells are leukocytes of the innate immune system and play a central role in the control of cancer metastases. NK cells and other innate immune cells often do not function well in patients with cancer and are also profoundly suppressed after cancer surgery. Dr. Auer's Lab and others have shown that NK cells are critically important in the clearance of tumor metastases and that their impairment can be recovered with immune therapy augmenting the innate immune system. Several studies suggest that cancer patients have depressed NK cell cytotoxicity as compared to healthy controls but that following resection of the cancer, NK cell cytotoxicity returns to normal levels. In this observational study, the investigators will measure NK cell cytotoxicity by the gold standard method (51Cr, a chromium51 release assay) and by a new interferon-ɣ (IFN-ɣ) based assay (NK-Vue™) in healthy humans and colorectal cancer (CRC) surgery patients seen a The Ottawa Hospital. The results of this study will determine if the NK-Vue™ is able to discriminate between healthy human volunteers and newly diagnosed cancer patients and is sufficiently sensitive to detect transient NK cell suppression immediately following surgery.
The purpose of this study is to evaluate the interface pressure measurements of applying self-adherent wraps on eyes after orbital tumour extirpation.
Previous studies showed that the role of the anesthesiologist, their education and role within the hospital is not known by the general public. The lack of knowledge about anesthesia can be an important factor in patients' fear before the planned surgery and can therefore impact patient's general satisfaction. By means of a survey in patients planned for elective surgery, the investigators want to investigate the perception of patients regarding the anesthesiologist, their education and role within the hospital, the general knowledge of the patient regarding anesthesia and possible pre-operative fears and concerns.
Multimodal analgesia, sometimes including intrathecal analgesia (IA), is essential in any enhanced recovery pathway (ERP). This study aimed to evaluate the safety, feasibility, and optimal IA regimen in colorectal surgical patients.
Despite improvements and advances in pancreas surgery, about 30-35% of patients who have pancreas surgery develop a type of complication called a pancreatic fistula. A pancreatic fistula occurs when fluid produced by the pancreas leaks into the abdomen after pancreas surgery. Patients who develop a pancreatic fistula can have poor short-term and long-term consequences.We are studying the effect of a medical device named HEMOPATCH on the development and seriousness of pancreatic fistulas. HEMOPATCH is a thin, flexible bovine protein-based pad that may improve tissue sealing where it is applied during surgery. Some small studies called case studies of between 2 and 7 patients, and two clinical trials have shown that HEMOPATCH is effective at stopping bleeding and reducing drain output after some types of surgery. However, there have been no completed clinical trials using HEMOPATCH to prevent or reduce pancreatic fistulas in patients having pancreas surgery, so we don't know if it works in this setting. Health Canada has approved the use of HEMOPATCH as a device to stop bleeding or seal other bodily fluids for procedures in which the control of bleeding or leakage of other body fluids or air by standard surgical techniques are either ineffective or impractical.
The study aims to verify if a short individual psychological intervention might increase perceived self-efficacy in managing preoperative anxiety in patients who will undergo pancreatic surgery. It is a randomized clinical trial where half of participants will attend a psychological intervention based on "the four elements protocol" by Elan Shapiro the day before surgery, while the other half will follow usual care.
Complications related to infant (≤ 1 year) airway management are under-appreciated because of few rigorous and targeted studies. Investigators have recently shown that multiple tracheal intubation (TI) attempts are a key risk factor for intubation-related complications in small children. Tracheal Intubation using Video laryngoscopy (VL) has become popular in anesthesiology practice because of several advantages over conventional direct laryngoscopy (DL). Studies show that VL improves the view of the airway compared to DL, requires fewer intubation attempts, but may take more time to intubate the trachea. This study compares first attempt success of VL to DL in infants presenting for elective surgery.
Within clinical settings observation of hemodynamic changes (e.g. mean systemic filling pressure, cardiac output) in critically ill patients with a clinical indication for deresuscitation with intravenous diuretic therapy.
