Remimazolam Is Associated with Superior Cerebral and Pulmonary Protection over Propofol in Elderly Thoracic Surgery: A Real-World Study Validated by Propensity Score Matching
Clinical Report: Comparative Analysis of Remimazolam and Propofol in Elderly Patients
Overview
This study compares remimazolam and propofol in elderly patients undergoing thoracic surgery, highlighting remimazolam's advantages in cognitive recovery, pulmonary function, hemodynamic stability, and reduced postoperative complications. The findings are based on a propensity score-matched analysis of 244 patients.
Background
Elderly patients undergoing thoracic surgery are at increased risk for postoperative complications, including cognitive decline and pulmonary issues. The choice of anesthetic can significantly impact recovery outcomes. Recent guidelines emphasize the importance of lung-protective ventilation and minimizing sedative use in this vulnerable population.

Key Findings
Remimazolam showed superior cognitive recovery with higher MMSE scores at multiple time points post-surgery.
Patients receiving remimazolam had better pulmonary function at 72 hours, indicated by higher FEV₁% predicted.
Enhanced hemodynamic stability was observed with remimazolam, including higher mean arterial pressure.
Lower incidence of postoperative delirium was noted in the remimazolam group compared to propofol.
Remimazolam was associated with a reduced rate of pulmonary complications post-surgery.
Clinical Implications
The findings suggest that remimazolam may be a preferable anesthetic choice for elderly patients undergoing thoracic surgery due to its association with improved cognitive and pulmonary outcomes. This could inform anesthetic protocols in enhanced recovery pathways.
Conclusion
This study provides evidence that remimazolam offers significant advantages over propofol in elderly patients undergoing VATS lobectomy, particularly in terms of cognitive recovery and postoperative complications.
