Association Between Dexmedetomidine Use and Duration of Invasive Mechanical Ventilation After Cardiac Surgery: A Hospital Registry Study
Main finding · Duration of mechanical ventilationResult — go to the resultAdjusted absolute difference 42 minutes 95% CI 11–75Authors' conclusion
Dexmedetomidine use, and a high sedative dose during mechanical ventilation were independently associated with prolonged mechanical ventilation after cardiac surgery. Among patients with a high sedative dose, dexmedetomidine was associated with shorter mechanical ventilation duration.
