Intravenous immunoglobulins in patients with COVID-19-associated moderate-to-severe acute respiratory distress syndrome (ICAR): multicentre, double-blind, placebo-controlled, phase 3 trial.

Background: Acute respiratory distress syndrome (ARDS) is a major complication of COVID-19 and is associated with high mortality and morbidity. We aimed to assess whether intravenous immunoglobulins (IVIG) could improve outcomes by reducing inflammation-mediated lung injury.

Methods: In this multicentre, double-blind, placebo-controlled trial, done at 43 centres in France, we randomly assigned patients (1:1) receiving invasive mechanical ventilation for up to 72 h with PCR confirmed COVID-19 and associated moderate-to-severe ARDS to receive either IVIG (2 g/kg over 4 days) or placebo.

Early abolition of cough reflex predicts mortality in deeply sedated brain-injured patients.

Background: Deep sedation may hamper the detection of neurological deterioration in brain-injured patients. Impaired brainstem reflexes within the first 24 h of deep sedation are associated with increased mortality in non-brain-injured patients. Our objective was to confirm this association in brain-injured patients.

Dysglycemia and Neurologic Outcome in Mechanically Ventilated Patients With Guillain-Barré Syndrome.

Objectives: Acute respiratory failure is a frequent complication of Guillain-Barré syndrome, associated with high morbidity and mortality. Adjuvant treatments are needed to improve the outcome of Guillain-Barré syndrome. Since dysglycemia is a risk factor for development of axonal polyneuropathy in critically ill patients and since insulin therapy may be neuroprotective, we sought to explore the association between dysglycemia and neurologic status in Guillain-Barré syndrome patients.

Mismatch negativity to predict subsequent awakening in deeply sedated critically ill patients.

Background: Mismatch negativity (MMN) is the neurophysiological correlate of cognitive integration of novel stimuli. Although MMN is a well-established predictor of awakening in non-sedated comatose patients, its prognostic value in deeply sedated critically ill patients remains unknown. The aim of this prospective, observational pilot study was to investigate the prognostic value of MMN for subsequent awakening in deeply sedated critically ill patients.

Effect of Noninvasive Ventilation After Unplanned Extubation.

Background: Our study set out to test the effect of noninvasive ventilation (NIV) performed after unplanned extubation.

Methods: Retrospective analysis of prospectively collected data in a university-affiliated mixed ICU of 12 beds during a 5-y period (January 2013 to December 2017). Unplanned extubation was defined as the occurrence of an unplanned removal of the endotracheal tube, whether deliberate or accidental.
