ICU sedation, delirium & recovery
Effects of dexmedetomidine on postoperative outcomes in adult non-cardiac surgical patients admitted to the intensive care unit: a systematic review and network meta-analysis of randomized controlled trials
Authors' conclusion
Dexmedetomidine may reduce postoperative delirium in non-cardiac surgical ICU patients but does not appear to improve ventilatory recovery or ICU length of stay and is associated with higher bradycardia risk. Its principal benefit lies in delirium prevention, supporting an individualised approach to sedative selection.
Study context
- Population
- Adults (≥18 years) admitted to the intensive care unit (ICU) after non-cardiac surgeryTwenty-four randomised controlled trials (RCTs) in the systematic review, 22 RCTs involving 2,544 patients contributed to the network meta-analysis · network meta-analysis (22 RCTs) 2,544
- Participants
- 2,777 adults
- Comparison
- Postoperative dexmedetomidine with normal saline or other sedatives
- Outcome
- Incidence of delirium during the ICU stay
- Follow-up
- During the ICU stay
