Interscalene Versus Infraspinatus-Teres Minor Blocks for Arthroscopic Shoulder Surgery
This randomized controlled trial aims to compare the effectiveness of interscalene (ISB) and infraspinatus-teres minor (ITM) blocks for postoperative analgesia in patients undergoing elective arthroscopic shoulder surgery. The primary outcome is total 24-hour opioid consumption. Secondary outcomes include pain scores, hemidiaphragmatic paresis incidence and severity, duration of analgesia, and changes …
Single-port Versus Multi-port Robotic Surgery for Rectal Cancer
Single-port versus multi-port robotic surgery for rectal cancer
Laser-assisted Ultrasound-guided Peripheral Vein Cannulation in Cardiac Surgery
The aim of this clinical trial is to investigate the advantages of single-operator laser-assisted ultrasound-guidance comparing with traditional ultrasound guidance in peripheral venous catheterization.The primary question addressed is whether single-operator laser-assisted ultrasound-guidance could improve the first-attempt success rate of peripheral venous catheterization compared with traditional ultrasound guidance.
Goal-directed Fluid Therapy During Deep Inferior Epigastric Perforator (DIEP) Free Flap Breast Reconstruction
Adequate free flap perfusion during Deep Inferior Epigastric Perforator (DIEP) flap breast reconstruction surgery requires maintaining blood pressure above 100 mmHg and avoiding excessive fluid administration. This study aims to determine whether the use of a measurement of preload dependency (Pulse Pressure Variation = PPV), can guide fluid therapy and …
Glucagon-like Peptide 1, Glucose Metabolism and Gastric Bypass
The overall goal of this project is to understand the mechanisms by which gastric bypass surgery improves glucose metabolism. The central hypothesis guiding this project is that the reconfiguration of intestinal transit with the Roux-en-Y will increase the release of insulinotropic GI hormones, termed incretins that improve insulin secretion and …
Evaluation of the Stress Response in Bariatric Surgery With and Without the Use of Opioids
The goal of this clinical trial is to compare Opioid Free and Opioid Based Anaesthesia in patients undergoing sleeve gastrectomy. The main questions it aims to answer are: Will the total dose of intraoperative opioid be reduced? Will there be difference in pain scores between groups? Participants will be managed …
Evaluation of the Implementation of a Diet Workshop on the 15th Postoperative Day Following Bariatric Surgery
The objective of the study was to improve protein intake after the implementation of a dietary workshop performed on the 15th postoperative day following bariatric surgery.
Multifidus Cervicis and Inter-Semispinal Plane Blocks in Analgesia After Cervical Spine Surgery
Major spine surgery with multilevel instrumentation is followed by a large amount of opioid consumption, significant pain, and difficult mobilization Pain is one of the main factors limiting ambulation, increasing the risk of thromboembolism by immobility, and causing metabolic changes that affect other systems. Therefore, individualized pain management with the …
Effect of Individualized PEEP on Postoperative Pulmonary Complication in Bariatrics
Ventilation with low tidal volume and high PEEP (positive end expiratory pressure) has been shown to improve oxygenation in patients with ARDS (acute respiratory distress syndrome). In obese patients undergoing laparoscopic bariatric surgeries, the risk of postoperative pulmonary complications (PPCs) increases significantly with general anesthesia. Previous studies have shown that …
Gut Microbiome and Sex as Risk Factors for Kidney Stones After Bariatric Surgery
This is a single-center study that aims to better understand how diet and sex affect the risk of kidney stones in people who have had gastric bypass surgery. Subjects will be asked to follow a special (clinic-provided) diet for six days and come to a research clinic for 3 study …
