Interscalene vs Phrenic-sparing Blocks in Obesity and Effect of Maximum Inspiratory Pressure
The goal of this clinical trial is to learn whether a phrenic-sparing nerve block can lower early breathing problems after shoulder surgery in adults with obesity, and whether a simple breathing-strength test (maximum inspiratory pressure, MIP) helps identify who is at higher risk. The main questions are: Does the phrenic-sparing …
Sevoflurane vs Propofol Anesthesia in Obese Patients Undergoing Lumbar Surgery
This randomized, single-center, single-masked clinical trial aims to compare the immunomodulatory effects of sevoflurane-based inhalational anesthesia and propofol-based total intravenous anesthesia in obese patients undergoing elective lumbar instrumentation surgery. Seventy patients will be randomized into two groups: a propofol group and a sevoflurane group. Blood samples will be collected preoperatively, …
Diagnosis of Postoperative Atrial Fibrillation by a Smartwatch
The incidence of postoperative atrial fibrillation (POAF) after on-pump cardiac surgery remains high, at around 30%. POAF increases the risk of cardiac decompensation, stroke, acute myocardial infarction, and death, resulting in increased morbidity and mortality, hospital length of stay, and cost of patient management. Episodes of POAF are usually paroxysmal …
Assessing the Burden of Perioperative Atrial Fibrillation in Patients Undergoing Cardiac Surgery
Background and Significance: In the United States approximately 220,000 patients undergo cardiac surgery per annum. Among potential complications, the incidence of atrial fibrillation (AF) is estimated at 30 - 60 %, and therefore presents the most common adverse event after cardiac surgery. Multiple complications may be associated with AF: Patients …
Diaphragmatic Inspiratory Amplitude as a Prognosticator for Postoperative Pulmonary Complications After Cardiac Surgery
Cardiac surgery is a critical intervention for a variety of cardiovascular conditions, yet it can frequently results in a spectrum of postoperative complications. Amongst various morbidities, Post-Operative Pulmonary Complications (POPCs) represent a significant clinical challenge leading to adverse outcomes like increased morbidity, mortality, and raised healthcare expenditures. The diaphragm, as …
Evaluation of Wellbeing and Patient Reported Outcomes After Open vs Robotic Mastectomy With DIEP Reconstruction
Nipple-sparing mastectomy (NSM) preserves the nipple-areolar complex (NAC) and is associated with improved cosmetic outcomes, body image, and patient satisfaction compared with more ablative techniques. Its use has expanded in both therapeutic and risk-reducing settings, including ductal carcinoma in situ (DCIS) and early-stage invasive breast cancer, where the NAC is …
Leica Microsystems Sponsored Study to Collect and Confirm Clinical Data on the Performance of the GLOW800 Device When Used in Accordance With Its Intended Use.
This post-market clinical follow-up (PMCF) study aims to confirm the safety and performance of the GLOW800 surgical microscope accessory when used in conjunction with the ARveo8x surgical microscope. The study evaluates fluorescence visualization and image quality during standard surgical procedures in the cerebral vascular area and plastic and reconstructive surgery. …
Evaluation of the Care Provided to Patients Who Underwent Bariatric Surgery and Were Lost to Follow-up 5 Years After Surgery
In 2025, bariatric surgery combined with nutritional and psychological support is one of the most effective treatments for patients with morbid obesity. (2)(3) However, it causes various deficiencies, such as vitamin and iron deficiencies, which justify lifelong personalised vitamin supplementation and, consequently, lifelong medical supervision. The latest recommendations from the …
Long-term Outcomes Sub-Study of Preoperative Combined Iron Therapy
This is a sub-study of the Preoperative Combined Iron Therapy trail in which some participants will be additionally randomized to combined iron supplementation or standarded treatment control to evaluate the impact on long-term outcomes.
Modeling Blood Management and Hemolytic Risk in Pediatric Heart Surgery
This study aims to learn more about blood management in children undergoing heart surgery, such as the right amounts, and the best blood products, to administer. It also aims to develop a mathematical model that may help researchers better predict and treat patients who need blood transfusions during heart surgery.
