From the Guidelines
The best next step in management for this 10-year-old boy is endotracheal intubation (option B). The patient is showing signs of respiratory failure despite aggressive treatment with bronchodilators, corticosteroids, magnesium sulfate, and noninvasive positive pressure ventilation. His oxygen saturation has dropped to 89% despite high oxygen supplementation (FiO2 0.6), and he has become agitated, which can be a sign of hypoxia and impending respiratory collapse. The arterial blood gas results show respiratory acidosis (pH 7.30, PaCO2 50 mm Hg) with hypoxemia (PaO2 52 mm Hg), indicating that the current respiratory support is inadequate.
Key Considerations
- The patient's clinical trajectory is worsening despite maximal medical therapy, as evidenced by the lack of significant improvement in symptoms and the development of respiratory acidosis.
- The diminished breath sounds suggest severe airflow limitation, which is a concern for impending respiratory failure.
- Intubation would secure his airway, allow for better ventilation and oxygenation, prevent further deterioration, and give his airways time to respond to the ongoing medical treatments.
Evidence-Based Decision
According to the BTS/ICS guideline for the ventilatory management of acute hypercapnic respiratory failure in adults 1, worsening physiological parameters, particularly pH and respiratory rate, indicate the need to change the management strategy, which may include proceeding to endotracheal intubation. Although this guideline is for adults, the principles of managing respiratory failure can be applied to pediatric patients, especially in life-threatening situations. The ERS/ATS clinical practice guidelines for noninvasive ventilation for acute respiratory failure 1 also support the use of noninvasive ventilation in certain clinical settings, but the patient's worsening condition despite maximal medical therapy and noninvasive ventilation suggests that endotracheal intubation is the best next step.
Clinical Implications
- The patient's condition requires immediate attention to prevent further deterioration and potential respiratory arrest.
- Endotracheal intubation will allow for more effective ventilation and oxygenation, which is critical in managing respiratory failure.
- The patient's airways will have time to respond to the ongoing medical treatments, reducing the risk of long-term complications.
From the Research
Patient Assessment
The patient is a 10-year-old boy with symptoms of rhinorrhea, congestion, cough, and wheezing that worsened over 6 hours prior to arrival. He has been treated with nebulized albuterol and ipratropium, intravenous corticosteroids, and intravenous magnesium sulfate, but showed no significant improvement in symptoms.
Current Status
The patient is currently in the intensive care unit, receiving continuous nebulized albuterol, intravenous terbutaline, and bilevel noninvasive positive airway pressure ventilation. His pulse oximetry shows 89% on 0.6 FiO2, and he has become agitated. Laboratory results indicate:
- Arterial blood gases: pH 7.30, PaO2 52 mm Hg, PaCO2 50 mm Hg
Management Options
Considering the patient's current status, the best next step in management is:
- Endotracheal intubation: The patient's agitation, decreased oxygen saturation, and hypercapnia (elevated PaCO2) suggest that noninvasive ventilation is not sufficient, and endotracheal intubation may be necessary to secure the airway and improve ventilation 2, 3. Other options, such as continued noninvasive ventilation with close observation, nebulized racemic epinephrine, needle thoracostomy, or tracheostomy, may not be the best next step in management given the patient's current condition.
Key Considerations
When considering endotracheal intubation, it is essential to:
