There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The cricothyroid membrane acts a route through which the upper airway can be accessed in order to provide oxygen and ventilation to patients. The need to provide oxygen and ventilation to patients is essential particularly under general anesthesia, where patients may lose the ability to breathe for themselves. Access through this membrane to provide oxygen and ventilation is critical in emergency situations where other traditional means to access the airway (e.g through endotracheal ventilation, supraglottic airway devices or face mask ventilation) have failed. It is known that due to the physiological changes of pregnancy, the upper airway of the body undergoes changes that can make accessing the airway through traditional means more difficult. Ultrasound is becoming increasingly popular due to its ability to identify the cricothyroid membrane, to improve success in accessing the airway through the cricothyroid membrane. Studies to date in non pregnant adults have shown that alterations in the head and neck position can alter the position and size of the cricothyroid membrane. No study to date however has looked at how changing the position of the head and neck effects the position and size of the cricothyroid membrane in pregnant patients. It is important to study these changes in the pregnant population, given the physiological changes of pregnancy that make accessing the airway through traditional methods more difficult in non pregnant patients. The investigators hypothesize that in pregnant patients in the third trimester, that changing the head from the neutral to maximally extended neck position will alter the position of the cricothyroid membrane in relation to anatomical skin markings between positions. The investigators also hypothesize that in pregnant patients in the third trimester that changing the head from the neutral to maximally extended neck position will increase the size of the cricothyroid membrane. The investigatorsalso aim to determine at what position in the neck a theoretical standardized incision will allow access to the cricothyroid membrane.
Virtual reality has been shown to be an effective way to treat pain and anxiety in various different settings. Palliative care is an area of medicine that often deals with patients suffering from pain and anxiety. The medication used to manage these symptoms are often opioids and benzodiazepines due to their rapid onset however they do have a significant side effect burden on patients. Very few studies have looked at the effect of virtual reality in this patient population. The goal of this study is to measure if virtual reality can decrease the required amount of medication used in managing pain and anxiety in palliative care. The secondary outcome will look at perceived benefit by patients
The study is a single blinded randomized control trial. Participants were blinded to the purpose of the study and to the level of noise they would be exposed. Anesthesiology residents and certified anesthesiologists were recruited.The goal of this study was to measure the time needed to initiate treatment(TNIT) of a severe bradycardia while performing a spinal anesthesia in a high-fidelity simulation environment with either a low or a high ambient dB-level.
The purpose of this study is to evaluate the safety, ability of GSK Biologicals' investigational RSV maternal vaccine (RSVPreF3) to generate an immune response and the degree to which the vaccine can cause side effects, when administered alone and in combination with Boostrix vaccine in healthy non-pregnant women 18-45 years of age. Two dose levels of RSVPreF3 and 2 Boostrix [Diphtheria, Tetanus and acellular Pertussis (dTpa) vaccine] formulations (US and ex-US) will be evaluated. A 2nd dose of RSVPreF3 will be administered in an extension of the study to assess the durability of the immune response after the first dose vaccination, and to assess the safety and immunogenicity following a second dose vaccination of the RSVPreF3 maternal vaccine.
The main objective is to compare the effectiveness of two readaptation programs post anterior cruciate ligament surgery. Laval University Rouge et or program is to be compared with the intervention guide from the CHU. Amateur athletes are recruited 3 months post ACL surgery. The level of confidence, symptoms, functional recovery level and muscle strength are assessed and compared between the two groups at 3, 4, 5, 6 and 9-month post surgery.
The main objective is to evaluate the FreeO2 device combined with noninvasive respiratory support technique for COPD patients and postoperative bariatric surgery patients. The main hypothesis is that FreeO2 device for oxygen therapy associated with NIV or nasal high flow oxygen therapy (NHFOT) allows to reach better oxygenation and avoid hypoxemia and hyperoxia.
Patients with breast cancer and metastatic axillary lymphadenopathy routinely undergo neo-adjuvant chemotherapy. For these patients, biopsy clip markers are inserted into the biopsy proven metastatic lymph node pre-treatment, as they may reach complete clinical response post-therapy. Limited axillary surgery, as opposed to a full axillary dissection, may then be indicated. It is still necessary to surgically excise the biopsy proven metastatic lymph node to accurately assess the pathologic response to therapy, and subsequently tailor post-surgical therapies appropriately. As such, these lymph nodes require pre-operative localization which, at The Ottawa Hospital, currently requires radioactive seed insertion under sonographic guidance, typically performed within 5 days of surgery. The procedure is often challenging, as both normal appearing lymph nodes and 3 mm biopsy clip markers are difficult and in some cases impossible, to visualize on ultrasound. At the time of surgery, the excised lymph node is radiographed, to ensure the radioactive seed and biopsy clip marker are both successfully excised. Localization with Ink has the potential to replace both the biopsy clip markers and radioactive seeds as the surgeons are able to directly visualize the Ink intra-operatively and excise the Inked lymph node. A preliminary study out of Stanford on 28 patients who underwent localization of axillary lymph nodes with Ink injected 1-211 days pre-operatively, in the pre neo-adjuvant and post neo-adjuvant settings, showed that lymph nodes injected with Ink are visible intra-operatively months after surgery, suggesting that this is a feasible localization technique (1).
The purpose of this study is to determine the effectiveness of darolutamide as part of adjuvant androgen deprivation therapy (ADT) with a luteinising hormone releasing hormone analogue (LHRHA) in men having radiation therapy for localised prostate cancer at very high risk of recurrence.
