The Physiologically Difficult Airway and Management Considerations

Abstract

Purpose of Review: This paper evaluates the recent literature regarding the physiologically difficult airway. Recent Findings: Adverse events mainly desaturation, cardiovascular collapse, and cardiac arrest remain common complications. This risk is greatly increased in patients with altered physiology prior to intubation. Studies published over the last 5 years have explored many aspects surrounding the epidemiology, risks, and approach to managing the physiologically difficult airway. Summary: Important work has been done to identify directly modifiable risks of complications related to the physiologically difficult airway, but a large percentage of patients remain at high risk despite optimizing induction agents, preoxygenation, and first attempt success.
