Apneic Oxygenation during Rapid Sequence Intubation in Critically Ill Children

Area of Science:

• Pediatric Critical Care Medicine
• Anesthesiology
• Respiratory Physiology

Background:

• Rapid sequence intubation (RSI) in critically ill children carries risks of hypoxemia.
• Apneic oxygenation (AO) is a technique to maintain oxygenation during airway manipulation.
• Limited data exists on AO safety and efficacy in pediatric RSI.

Purpose of the Study:

• To evaluate hypoxemia and complications of AO during RSI in critically ill children.
• To determine the safety and tolerability of AO in this vulnerable population.

Main Methods:

• Prospective case series of 44 critically ill pediatric patients undergoing RSI.
• Apneic oxygenation administered via nasal cannula at age-adjusted flow rates (5-15 L/min).
• Oxygen saturation (SpO2) monitored pre- and post-intubation attempt.

Main Results:

• Mean pre-intubation SpO2 was 98.9%, decreasing to 90.7% post-intubation.
• Hypoxemia (SpO2 < 80%) was significantly less frequent with one intubation attempt (p < 0.001).
• No serious complications were observed; AO was well-tolerated.

Conclusions:

• Apneic oxygenation is a safe and effective adjunct during RSI in critically ill children.
• Minimizing intubation attempts is crucial for maintaining adequate oxygenation.
• Further research can explore optimal AO parameters in pediatric RSI.
