Pharmacokinetic and pharmacodynamic study of dexmedetomidine in elderly patients during spinal anesthesia.
The application of dexmedetomidine in patient sedation is generally accepted, though its clinical application is limited because of the lack of information detailing the specific properties among diverse populations of patients. The aim of this study was to compare the pharmacokinetic and pharmacodynamic characteristics of dexmedetomidine between elderly and young patients during spinal anesthesia. ⋯ The clearance of dexmedetomidine in elderly patients showed a declining trend compared to young patients. Interventions in the elderly group were more frequent than in the young group, and the elderly group showed significant adverse effects. It is suggested that elderly patients who use dexmedetomidine may benefit from a different dose. However, further research with a larger population size is required to confirm these findings.
