Effect of age on dexmedetomidine treatment for ventilated patients with sepsis: a post‐hoc analysis of the DESIRE trial
2021
Overview
Aim There are no definitive data to determine whether age influences the effects of dexmedetomidine (DEX) treatment. Thus, we investigated whether older age was associated with more favorable sedative action by DEX in sepsis patients who required mechanical ventilation. Methods This study involved a post‐hoc analysis of data from the Dexmedetomidine for Sepsis in the ICU Randomized Evaluation (DESIRE) trial. The patients were categorized based on median age into elderly and younger groups. The two groups were then compared during the first 7 days after ventilation based on proportion of patients with well‐controlled sedation (Richmond Agitation–Sedation Scale score between −3 and +1), days free from delirium (based on the Confusion Assessment Method for ICU), and days free from coma (Richmond Agitation–Sedation Scale score between −4 and −5). Results One hundred and one patients were assigned to the elderly group and 100 patients were assigned to the younger group. In the elderly group, 50 patients received DEX treatment and 51 patients received non‐DEX treatment, with the DEX arm having significantly better‐controlled sedation (range, 14–52% versus 16–27%; P = 0.01). In the younger group, 50 patients received DEX treatment and 50 patients received non‐DEX treatment, with no significant difference in the proportions of well‐controlled sedation (range, 20–64% versus 24–60%; P = 0.73). There were no significant differences in the numbers of days free from delirium or coma between the groups. Conclusion In elderly sepsis patients who require ventilation, dexmedetomidine could be more effective than other sedative agents for achieving proper sedation. Dexmedetomidine is more effective than other sedative agents for proper sedation in septic elderly patients requiring mechanical ventilation.
