Higher oxygen saturation, lower rates of severe hypoxemia versus no ventilation.
Critically ill patients who underwent tracheal intubation had higher oxygen saturation and a lower incidence of severe hypoxemia with bag-mask ventilation, according to results of the PreVent trial.
In a sample of about 400 critically ill patients, those who received bag-mask ventilation in the interval between induction and laryngoscopy had a lower incidence of severe hypoxemia (oxygen saturation <80%) compared with patients who did not receive ventilation (10.9% vs 22.8%, relative risk 0.48, 95% CI 0.30-0.77), and the bag-mask ventilation group had a nadir oxygen saturation 3.9 percentage points higher, reported Jonathan Casey, MD, of Vanderbilt University Medical Center, and colleagues.
