Liberation from Invasive Mechanical Ventilation with Continued Receipt of Vasopressor Infusions.
Rationale: Weaning protocols for discontinuation of invasive mechanical ventilation often mandate resolution of shock. Whether extubation while receiving vasopressors is associated with harm is uncertain. Objectives: To examine whether extubation while still receiving vasopressors is associated with worse outcomes. ⋯ Extubation on high-dose vasopressors (>0.1 μg/kg/min) was associated with a greater hazard of reintubation (SHR, 2.25 [1.01-4.98]; P = 0.046) compared with extubation after vasopressor discontinuation. Meanwhile, extubation on low-dose vasopressors (⩽0.1 μg/kg/min) was associated with a lower mortality (hazard ratio, 0.69 [0.51-0.91]; P = 0.01) and a shorter ICU LOS (SHR, 1.34 [1.09-1.65]; P = 0.01), but no difference in reintubation or hospital LOS as compared with those weaned off vasopressors. Conclusions: Extubation while receiving high-dose but not low-dose vasopressors was associated with an increased risk of reintubation.
