Perioperative Management

This study aims to evaluate the changes between preoperative and postoperative serum chloride levels in patients undergoing HoLEP surgery and to investigate the metabolic and clinical effects of this change. The study is observational, and no additional interventions will be performed.

The goal of this clinical trial is to evaluate the feasibility of two different preoperative hemodialysis schedules for people with end-stage kidney disease (ESKD) who undergo surgical procedures. The main questions it aims to answer are: Is it feasible to randomize participants with ESKD undergoing nonemergent surgical procedures to same-day hemodialysis versus no same-day hemodialysis? Is it safe to randomize participants with ESKD undergoing nonemergent surgical procedures to same-day hemodialysis versus no same-day hemodialysis? Researchers will compare the two hemodialysis schedules to see if the scheduling and safety profiles are the same. Participants will: Answer questions about their health up to 4 weeks before and 4 weeks after the surgical procedure. Receive hemodialysis on the day of the surgical procedure or not, depending on the study treatment assignment.

This study aims to develop and evaluate an integrated perioperative management system based on wearable devices and a digital rehabilitation platform for patients with non-small cell lung cancer (NSCLC) undergoing thoracic surgery. By combining preoperative functional assessment using the six-minute walk test (6MWT), continuous perioperative physiological monitoring, and structured postoperative home-based digital rehabilitation, this randomized controlled trial will investigate whether the wearable-based digital management model improves short-term postoperative pulmonary function, functional recovery, and clinical outcomes compared with standard perioperative care.

The goal of this observational study is to explore the value of eye-tracking technology in perioperative management and teaching. The study aims to understand how eye-tracking can help analyze the attention distribution of clinicians during perioperative procedures and optimize workflows for improved safety and teaching outcomes. The main questions it seeks to answer are: How does eye-tracking technology reveal the focus distribution patterns of experienced and novice clinicians in perioperative scenarios? Can visualizing expert clinicians' eye movement patterns improve the learning outcomes and operational skills of medical students? Participants include anesthesiologists and medical students involved in perioperative management training. Eye-tracking data, such as fixation duration, fixation count, and heatmaps, will be collected during surgical and training scenarios. The study will analyze correlations between attention distribution and operational performance. This research will provide insights into optimizing perioperative safety and revolutionizing medical education using objective attention data.
