Intubation in the Critically Ill: When, How, and How Long?

Area of Science:

• Critical Care Medicine
• Respiratory Physiology
• Mechanical Ventilation

Background:

• Endotracheal intubation is a common but high-risk procedure in critical care.
• Decisions regarding intubation are complex, relying on clinical judgment rather than strict criteria.
• Noninvasive ventilation offers an alternative to delay or avoid intubation in select cases.

Purpose of the Study:

• To provide guidance on the optimal timing, methods, and duration of endotracheal intubation.
• To discuss strategies for physiological optimization and personalized ventilation prior to intubation.
• To highlight the importance of daily assessment for extubation readiness.

Main Methods:

• This is a narrative review.
• Literature search on endotracheal intubation, noninvasive ventilation, and mechanical ventilation strategies.
• Synthesis of current evidence and clinical recommendations.

Main Results:

• Intubation decisions require careful consideration of patient-specific factors and clinical trajectory.
• Physiological optimization and tailored ventilatory settings can mitigate risks associated with intubation.
• Early and regular assessment of extubation readiness is crucial for patient recovery.

Conclusions:

• Endotracheal intubation should be approached with caution, emphasizing risk mitigation and patient-centered care.
• Noninvasive ventilation and pre-intubation optimization are key strategies for managing respiratory failure.
• A systematic approach to extubation readiness assessment facilitates timely liberation from mechanical ventilation.
