A Randomized, Controlled Clinical Trial Comparing Remimazolam Besylate Combined With Alfentanil Versus Propofol Combined With Alfentanil for Anesthesia in Thoracic Surgery

Title: A Clinical Study Comparing Two Anesthesia Methods for Chest Surgery Why is this study being done? Chest surgeries (like lung surgery) require safe and stable anesthesia. Currently, a drug called propofol combined with an opioid painkiller (alfentanil) is commonly used. However, propofol can sometimes cause low blood pressure and low oxygen levels. A newer drug called remimazolam may cause fewer of these side effects. This study aims to compare the safety and effectiveness of remimazolam (combined with alfentanil) versus propofol (combined with alfentanil) for anesthesia during chest surgery. What will happen in the study? Patients scheduled for elective chest surgery will be invited to participate. If they agree, they will be randomly assigned (like flipping a coin) to one of two groups: * Group 1: Will receive remimazolam and alfentanil for anesthesia. * Group 2: Will receive propofol and alfentanil for anesthesia (standard care). The anesthesiologist will carefully monitor patients during and after surgery. We will mainly compare how often patients in each group experience two safety issues: low oxygen levels in the blood and low blood pressure. We will also record recovery times, drug doses, side effects, and ask patients and surgeons about their satisfaction. Who can participate? Adults aged 18-65 who are scheduled for elective chest surgery and are in relatively stable health (ASA physical status I-III). Where is the study taking place? This study will be conducted in the Department of Anesthesiology at The First Affiliated Hospital of Xinxiang Medical College, Henan, China. Ethics Approval: This study has been reviewed and approved by the Ethics Committee of The First Affiliated Hospital of Xinxiang Medical College (Approval Number: (2025) Medical Ethics Committee Approval No. 29).

Tubeless VATS for Mediastinal Neoplasm

In recent year, non-intubated anesthesia had emerged as an available and promising alternative for thoracic procedure. However, its safety and feasibility in video-assisted thoracoscopic surgery (VATS) for mediastinal neoplasm remain controversial. This randomized controlled trial is designed to evaluate the impact of the non-intubated approach on surgical and perioperative outcomes in patients undergoing mediastinal neoplasm resection.
