PURPOSE OF REVIEW: Despite improvements over time, cardiac arrest continues to be associated with high rates of mortality and morbidity. Several methods can be used to achieve airway patency during cardiac arrest, and the optimal strategy continues to be debated. This review will explore and summarize the latest published evidence for airway management during cardiac arrest.

RECENT FINDINGS: A large meta-analysis of out-of-hospital cardiac arrest (OHCA) patients found no difference in survival between those receiving tracheal intubation and those treated with a supraglottic airway (SGA). Observational studies of registry data have reported higher survival to hospital discharge in patients receiving tracheal intubation or an SGA but another showed no difference. Rates of intubation during in-hospital cardiac arrest have decreased in the United States, and different airway strategies appear to be used in different centres.

SUMMARY: Observational studies continue to dominate the evidence base relating to cardiac arrest airway management. Cardiac arrest registries enable these observational studies to include many patients; however, the design of such studies introduces considerable bias. Further randomized clinical trials are underway. The current evidence does not indicate a substantial improvement in outcome from any single airway strategy.
