Recognizing a potentially difficult intubation can help clinicians prepare for complications by getting assistance from colleagues with airway training and by ensuring advanced airway management equipment is available. Michael E. Detsky, MD, MSHP, assistant professor of medicine at the University of Toronto and the Mount Sinai Health System, discusses findings from a Rational Clinical Examination systematic review identifying physical findings and risk factors that can help predict difficult endotracheal intubation.

Critically ill patients often require IV fluids for resuscitation but questions remain about the optimal type of IV fluid and best rate of IV fluid bolus infusion. JAMA Associate Editor Kristin Walter, MD, MS, discusses a recent clinical trial that examined the effect of 2 different crystalloid solutions and 2 IV fluid bolus infusion rates on ICU patient mortality with Alexandre B. Cavalcanti, MD, PhD, director of the Research Institute HCor in San Paulo, Brazil, and Craig M. Coopersmith, MD, professor of surgery and director of the Critical Care Center at Emory University School of Medicine in Atlanta, Georgia.
