Anticipated and unanticipated difficult airway management.

Area of Science:

• Anesthesiology
• Emergency Medicine
• Critical Care

Background:

• Difficult airway management remains a significant challenge in clinical practice.
• Despite technological advancements, optimal strategies are still evolving.

Purpose of the Study:

• To review current research on difficult airway management.
• To provide an update on recent findings and best practices.

Main Methods:

• Literature review of current scientific research.
• Synthesis of evidence on new technologies and techniques.

Main Results:

• New intubation technologies increase provider confidence but lack evidence for reducing cannot intubate cannot ventilate (CICV) events.
• Optimization of mask ventilation is underappreciated but vital for reducing difficult mask ventilation.
• Enhanced preoxygenation extends safe apnea time, potentially improving outcomes during CICV.

Conclusions:

• Effective difficult airway management requires optimized mask ventilation, appropriate intubation tools, and maximized safe apnea oxygenation.
• Prompt surgical airway is indicated for severe hypoxia when noninvasive interventions fail.
• A simplified, concise algorithm for difficult airway management is needed for practical application.
