Discussion

Prospective observational study evaluates sedation's impact on delirium in geriatric patients, indicating no significant differences in methods.

No significant difference in postoperative delirium rates was found between dexmedetomidine and remifentanil sedation methods.
Group D patients showed a significant decrease in mean arterial pressure during surgery at multiple time points.
This observational clinical study involved patients aged 65 and older undergoing lower extremity surgery with spinal anesthesia.
The findings suggest that sedation protocols in geriatric patients yield similar delirium outcomes; further research may be needed.

Gazioğlu et al. (2025) studied this question.
