This systemic review and meta analysis looked at major adverses events (hypoxia, cardiovascular instability, or cardiac arrest) in patients intubated in emergency departments, ICU’s, or medical floors. They found nearly 1/3 of patents had an event. ICU intubation and patients with pre-existing hemodynamic compromise had the highest rate of adverse outcomes. This study gives further support to the concept of maximizing resuscitation pre-intubation and to anticipate a major event peri-intubation. Be prepared and don't be surprised when something doesn't go as planned.
