The Effect of Adding an IPACK Block to the Adductor Canal Block on Total Knee Arthroplasty Surgery
Total knee arthroplasty (TKA) is a frequently performed major orthopedic surgery, where most patients experience severe postoperative pain. Pain-related delays in patient mobilization can lead to thromboembolism, deep vein thrombosis, surgical site infection, and increased risk of hospital-acquired infections due to prolonged hospital stay. Optimal postoperative knee analgesia is crucial …
A Prospective Cohort Study on Visual Function and Psychological Conditions Before and After Surgery for Congenital Ptosis
The goal of this observational study is to learn about the 6-month effects of Levator Resection combined with Fascial Sheath Suspension surgery in patients who undergo this procedure to treat congenital ptosis. The main questions it aims to answer are: Does this combined surgery improve best-corrected visual acuity, stereopsis, and …
Comparing the Postoperative Analgesic Efficacy of Anterior Iliac Block and Ilioinguinal-iliohypogastric Block in Inguinal Hernia Surgery
The primary aim of this study is to compare two postoperative analgesia techniques used in patients undergoing inguinal hernia surgery-(1) the anterior iliac block and (2) the ilioinguinal/iliohypogastric block-in terms of postoperative analgesia duration and patient satisfaction. Effective postoperative analgesia in inguinal hernia surgery is crucial for improving patient comfort …
Ultrasound-Guided Erector Spinae Plane Block Versus Thoracoscopically-Guided Intercostal Nerve Block in Video-Assisted Thoracoscopic Surgery
Effective postoperative pain management is essential after thoracic surgery. Insufficient pain control may impair breathing and coughing, increasing the risk of pulmonary complications such as collapsed lungs (atelectasis) or pneumonia. Although minimally invasive lung surgery (video-assisted thoracoscopic surgery, VATS) is less painful than open surgery, people can still have significant …
Effects of Preoperative Sleep Disorders on Perioperative Anesthesia Depth and Recovery Quality in Patients Undergoing Noncardiac Surgery
A Single-Center, Prospective Observational Cohort Study Comparing Perioperative Electroencephalographic Anesthesia Depth Parameters (Electroencephalographic Index, SE/RE Entropy, Burst Suppression Ratio) Between Patients With Preoperative Sleep Disorders and Those Without; To Identify the Independent Effects of Preoperative Sleep Disorders on the Speed of Electroencephalographic Recovery During Emergence, Electroencephalographic Status at Extubation, Intra-PACU …
Comparing the Incidence of Parastomal Hernia After Mesenteric Molding Suturing and Non-molding Suturing in Colostomy Surgery
\*\Research Background\\* Colostomy surgery is a common surgical procedure widely used for the treatment of various gastrointestinal diseases, including rectal cancer, ulcerative colitis, and Crohn's disease. Although this surgery can significantly improve patients' quality of life and prognosis, the incidence of postoperative complications, particularly parastomal hernia (PSH), is relatively high. …
Clinical Effects of Intraoperative Heat and Moisture Exchange Systems During Thoracic Surgery: A Prospective Observational Cohort Study
General anesthesia with endotracheal intubation bypasses the physiological warming and humidification functions of the upper airway, allowing cold and dry gases to reach the lower respiratory tract. This may impair mucociliary clearance, increase secretion viscosity, promote atelectasis, and contribute to postoperative pulmonary complications (PPCs). Patients undergoing thoracic surgery, particularly those …
Effect of Postoperative Analgesia of Oliceridine Fumarate for Gastrointestinal Function Recovery in Patients Undergoing Lumbar Spine Surgery
Osemitidine fumarate is a novel G protein-biased ligand μ-opioid receptor agonist. Previous studies have confirmed its potent analgesic effects and safety: compared with morphine, it reduces respiratory depression and gastrointestinal dysfunction. This study aims to evaluate the effects of osemitidine on postoperative gastrointestinal function recovery and pain in patients undergoing …
Adding a Live Biotherapeutic Product (CBM588) to Pembrolizumab for the Treatment of Renal Cell Cancer After Surgery
This phase II trial compares the effect of adding a Live Biotherapeutic Product called CBM588 to pembrolizumab versus pembrolizumab alone in preventing return of disease (recurrence) after surgery for patients with renal cell cancer. Pembrolizumab is an immune checkpoint inhibitor. Immunotherapy with monoclonal antibodies such as pembrolizumab may help the …
Assessment of Renal Perfusion Using Ultrasound and Near-Infrared Spectroscopy in Patients Undergoing Minimally Invasive Abdominal Surgery
This prospective observational study aims to evaluate renal perfusion in adult patients undergoing elective minimally invasive abdominal surgery. Renal perfusion will be assessed using two non-invasive monitoring techniques: Doppler ultrasonography-derived Renal Resistive Index (RRI) and Near-Infrared Spectroscopy (NIRS)-derived renal regional oxygen saturation (rSO₂). Measurements will be obtained at predefined perioperative …
