PCCRG aims to improve care for critically ill patients by using clinical trials to compare commonly used treatments in this setting. These studies span multiple areas of critical care medicine including non-invasive and invasive respiratory support, fluid management, and endotracheal intubation.

The goal of the RSI trial is to learn which of two drugs (“ketamine” or “etomidate”) is best for patients receiving a breathing tube – overall and for specific groups of patients with medical problems like heart disease or severe infection.

Clinicians perform rapid sequence induction, laryngoscopy, and tracheal intubation for more than 5 million critically ill adults as a part of clinical care each year in the United States. One-in-ten emergency tracheal intubations is complicated by life-threatening hypoxemia. Administering supplemental oxygen prior to induction and intubation (“preoxygenation”) decreases the risk of life-threatening hypoxemia. In current clinical practice, the most common methods for preoxygenation are non-invasive positive pressure ventilation and facemask oxygen. Prior trials comparing non-invasive positive pressure ventilation and facemask oxygen for preoxygenation have been small and have yielded conflicting results. A better understanding of the comparative effectiveness of these two common, standard-of-care approaches to preoxygenation could improve the care clinicians deliver and patient outcomes.
