Filter by:A retrospective observational dual center study investigating side effects and major complications after thoracic epidural insertion according to local safety protocols.
The goal of this study is to compare the efficacy in controlling postoperative pain of paravertebral block (PVB) with methylene blue visual confirmation and thoracic epidural anesthesia (TEA). This is a single center, parallel-group, prospective study. Patients will be randomly assigned in a 1:1 ratio to receive either PVB or TEA. Primary end-point is pain relief measured with Postoperative Numeric Rating Scale. The secondary end-points are time to perform TEA and PVB, total opioid consumption, postoperative outcomes.
We will conduct a prospective clinical study involving up to 40 non-Small Cell Lung Cancer (nSCLC) patients to determine dose thresholds for central and peripheral BSS elements. All imaging will be performed under motion control (e.g., with or without abdominal compression) defined as breathing with a resultant motion ≤5mm by fluoroscopy. In this study, a high-resolution breath-hold CT scan (BHCT) will be acquired from each patient immediately before or after the 4DCT scan. A follow-up high resolution BHCT (also under motion control) will be acquired from each patient 8-12 months post-SabR, and BSS elements will be segmented in LungPointRT. A radiation oncologist will compare the pre- and post-SabR contours to determine segmental collapse.
To evaluate the effectiveness of ultrasound guided Erector Spinae Plane Block (ESPB) in controlling post thoracotomy ipsilateral shoulder pain.
The goal of this study was to test the safety and efficacy of this stapler in our general thoracic surgery practice.
This pilot study will examine facilitators and barriers that impact staff uptake for implementation of practice change involving ipsilateral IV insertion in patients with axillary lymphadenectomy/dissection in a single radiology center.
This is a study evaluating the safety and efficacy of Lattice SBRT for patients with large tumors (≥ 4.5 cm) planning to undergo palliative radiotherapy.
This study aims to measure diaphragmatic dysfunction with ultrasonography and nerve stimulation of the phrenicus nerve, in patients undergoing thoracic surgery for lung and esophageal cancer, and correlate measures of diaphramatic function to clinical postoperative endpoints.
Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration is a procedure used to obtain tissue samples (biopsies) of lymph nodes near the airways or of lung tumours growing in close proximity to the airways. Briefly, an endoscope with an ultrasound probe which is inserted through the mouth and into the airways. Once in the airways, the ultrasound allows for identification of the optimal biopsy site; a hollow biopsy needle is then inserted into the tissue under real-time ultrasound visualization and a sample is extracted. In the investigator's centre, the extracted sample is then immediately subjected to rapid on-site evaluation (ROSE). During the ROSE procedure, a cytotechnologist uses part of the sample to make a limited number direct smears which are then rapidly stained and evaluated under a microscope by the cytotechnologist. The cytotechnologist provides an assessment of the adequacy of the sample for diagnosis. The respirologist performing the EBUS then uses this information to: i) determine whether additional sampling is required, and ii) triage any additional samples for ancillary studies as needed. A final cytopathological diagnosis is established several days later, when all of the material from the procedure (including the material not evaluated at ROSE) is examined by a cytopathologist. There are different techniques which are utilized to perform the needle aspiration biopsy. Suction aspiration (where pressure suction is applied to the needle to draw out material) which is the standard at many centres around the world and capilliary suction (where a tiny wire is drawn back slowly to create more gentle suction force) which is utilized often at LHSC. The purpose of this study is to evaluate for differences in ROSE adequacy between these two methods.
This study will compare a web-based advance directive to a standard advance directive.
