Quality of Recovery-15 After Opioid-free Versus Opioid-based General Anesthesia in Major Urological Surgery
This randomized controlled trial evaluates postoperative quality of recovery assessed with the Quality of Recovery-15 questionnaire in adult patients undergoing elective major urological surgery under opioid-free versus opioid-based general anesthesia. Opioid-free anesthesia is a multimodal anesthetic technique that avoids intraoperative opioids by combining non-opioid analgesic and sympatholytic agents such as …
Anterior Suprascapular Versus Interscalene Block for Postoperative Analgesia After Arthroscopic Shoulder Surgery in the Outpatient Setting
Shoulder surgery performed in the outpatient setting can be associated with moderate to severe postoperative pain, especially during the first hours after surgery. Regional anesthesia is commonly used to improve postoperative pain control, reduce opioid use, and support early recovery and safe discharge. The interscalene block (ISB) is widely considered …
Intravenous Dexamethasone With Single-Shot Versus Continuous Brachial Plexus Block for Rebound Pain After Shoulder Surgery
Shoulder surgery often causes severe pain after the operation. To control this pain, doctors commonly perform a nerve block (interscalene brachial plexus block), which numbs the shoulder area. However, when the effect of a single-injection nerve block wears off, many patients experience sudden, intense pain known as "rebound pain". One …
Optimized Cardiopulmonary Bypass Flow Strategy Based on Ideal Body Weight in Obese Patients Undergoing Cardiac Surgery
Cardiopulmonary bypass (CPB) pump flow is typically calculated according to body surface area (BSA) derived from actual body weight and temperature, following the 2024 European guidelines recommending an indexed flow of 2.4 L/min/m². However, in obese patients, using actual weight leads to a high BSA and thus elevated pump flow, …
Comparison Between Ultrasound Guided Pericapsular Nerve Block And Suprainguinal Fascia Iliaca Nerve Block in Hip Surgery
Hip fracture is a common orthopedic emergency in the elderly, and it is associated with significant morbidity and mortality. Surgical reduction and fixation are the definitive treatment in most patients, effective perioperative analgesia that minimizes the need for opioids and related adverse effects (such as delirium) is essential in this …
The Predictive Value of Doppler Based Renal Ultrasound and Urinary Oxygen Tension for Prediction of Acute Kidney Injury After Open Heart Surgery
This study aims to investigate the predictive value of Doppler-based renal ultrasound and urinary oxygen tension in the development of acute kidney injury after cardiac surgery.
Prophylactic Use of Tamsulosin in the Prevention of Post-operative Urinary Retention in Men After Rectum Resection
The study will be a phase III double-blind randomized clinical trial. Participants will be recruited from the Department of General Surgery of the CHU de Québec - Saint-François-d'Assise and Hôtel-Dieu de Québec. The primary outcomes are the incidence of postoperative urinary retention in men undergoing rectal resection and the efficacy …
Comparison of Ultrasound-Guided Serratus Combination Plane Blocks and Local Wound Infiltration for Postoperative Analgesia Management in Minimally Invasive Cardiac Surgery (MICS)
This randomized, prospective, single-blinded study aims to compare the efficacy of ultrasound-guided serratus anterior plane (SAP) block combined with serratus-intercostal interfascial plane (SIP) block versus local wound infiltration (LWI) for postoperative analgesia in patients undergoing minimally invasive cardiac surgery (MICS). The primary outcome is total perioperative and postoperative opioid consumption. …
MITRIS China Post Market Clinical Follow-up (PMCF) Study
Collect clinical outcomes on acute and long-term safety and performance of the MITRIS RESILIA Mitral Valve, Model 11400M, in subjects requiring replacement of their native or prosthetic mitral valve with or without concomitant procedures.
Comparing Patient Reported Outcomes and Clinical Outcomes Based on Different Scar Placement in Patients Undergoing Standard Breast Conserving Surgery for Breast Cancer: The PROM-S Study.
This study is for patients with breast cancer and the objective is to compare patient reported outcome measures (PROMs) based on scar placement in patients undergoing standard breast-conserving surgery (sBCS). BCS has become the standard of care for eligible patients with breast cancer (current UK national BCS rate is 60%). …
