Effect of Ultrasound-Guided Quadro-Iliac Plane Block on Postoperative Analgesia After Lumbar Spinal Surgery
This prospective observational study aims to evaluate the effect of ultrasound-guided Quadro-Iliac Plane Block (QIPB) on postoperative analgesia in patients undergoing lumbar spinal surgery. Lumbar spinal procedures are commonly associated with significant postoperative pain, which may impair early mobilization and increase opioid consumption. In routine clinical practice, QIPB is increasingly …
Wound Healing and Bacterial Adherence With Triclosan-Coated Sutures After Mandibular Impacted Third Molar Surgery
The goal of this clinical trial is to learn if triclosan-coated absorbable stitches (polyglactin 910 sutures coated with triclosan, an antibacterial agent) help soft tissue heal better and have fewer bacteria stuck to the stitches after lower impacted wisdom tooth surgery in adults aged 18 to 35 years. The main …
The Impact of Multiple Antihypertensive Therapy on Post-Induction Hypotension Burden in Cardiac Surgery Patients
This study aims to investigate the impact of multiple preoperative antihyperstensive drug use on the burden of post-induction hypotension (PIH) in patients undergoing elective cardiac surgery. The researchers will observe whether the combination of different antihypertensive classes (such as ACE inhibitors, ARBs, beta-blockers, and calcium channel blockers) leads to a …
Effects of Menstrual Cycle on Optic Nerve Sheath Diameter in Patients Undergoing Laparoscopic Gynecologic Surgery
This observational study aims to evaluate the effect of menstrual cycle phase on optic nerve sheath diameter (ONSD) in women undergoing elective laparoscopic gynecologic surgery. Patients will be grouped according to menstrual cycle phase as follicular or luteal. ONSD measurements will be performed perioperatively, and postoperative nausea and vomiting as …

Effect of Oxygen Administration in the Non-dependent Lung on Postoperative Complications After Lung Surgery
The purpose of this study is to analyze the effectiveness of apneic oxygenation and CPAP applied to the non-dependent lung during pulmonary resection surgery in reducing inflammatory response, ischemia-reperfusion injury, and postoperative complications. We will conduct a randomized, controlled, and blinded study in 177 patients with three arms: Control Group: …
A Study of Botensilimab and Balstilimab for Colorectal Cancer With ctDNA+ After Surgery and Chemotherapy
The researchers are doing this study to find out whether the combination of botensilimab and balstilimab (BOT/BAL), followed by balstilimab alone, is an effective treatment for people with microsatellite stable (MSS) colorectal cancer or colorectal liver metastases (CRLM) who have measurable residual disease (MRD) after standard treatment with surgery and …
