Interventions to Reduce Risk in the Physiologically Difficult Pediatric Airway: A Descriptive Study and Exploratory...

Area of Science:

• Pediatric Emergency Medicine
• Critical Care
• Airway Management

Background:

• Physiologically difficult airways in pediatric emergency departments (PEDs) pose a high risk for peri-intubation cardiac arrest.
• Preintubation interventions aim to stabilize patients but their use and effectiveness are unclear.

Purpose of the Study:

• To describe the utilization of preintubation interventions in pediatric patients with physiologically difficult airways.
• To determine if these interventions are associated with a reduction in peri-intubation cardiac arrest.

Main Methods:

• Secondary analysis of a multicenter, retrospective cohort of 332 patients (<21 years) undergoing rapid sequence intubation in 8 academic PEDs.
• Patients met criteria for a physiologically difficult airway.
• Examined administration rates of IV fluids, vasoactive medications, and sodium bicarbonate; assessed association with cardiac arrest using propensity scores.

Main Results:

• 80% of patients received at least one intervention; IV fluids (77%), vasoactive medications (26%), and sodium bicarbonate (6%).
• Significant site-to-site variability in intervention administration rates was observed.
• Preintubation interventions were not significantly associated with a reduction in peri-intubation cardiac arrest (OR 1.59).

Conclusions:

• Wide variability exists in preintubation intervention use for pediatric patients with difficult airways.
• Current preintubation interventions were not linked to decreased peri-intubation cardiac arrest.
• Prospective studies are necessary to evaluate interventions for preventing cardiac arrest during pediatric intubation.
