Effects of Remimazolam on Neurocognitive Function in Patients Undergoing Cardiovascular Surgery

The goal of this observational study is to explore the effect of remimazolam-based total intravenous anesthesia on postoperative neurocognitive function in patients who undergo cardiovascular surgery. The main question this study tries to answer is: Does remimazolam influence the incidence of postoperative delirium in cardiovascular surgery? Participants already apply remimazolam-based total intravenous anesthesia as part of their regular medical treatment for general anesthesia to perform cardiac surgery will answer questionnaires about cognitive function after surgery.
