What is the initial management for negative pressure pulmonary edema after extubation due to laryngospasm?

• A. Open the airway and reintubate
• B. Diuretics
• C. Inhaled bronchodilators
• D. Steroids

Answer: (A)

Negative pressure pulmonary edema happens when a strong inspiratory effort is made against an obstructed upper airway, such as after laryngospasm. The forceful trying to breathe against a closed glottis creates markedly negative intrathoracic pressure, pulling fluid from the vasculature into the alveoli and causing rapid pulmonary edema and hypoxemia. Because the problem is the airway obstruction, the first priority is to relieve that obstruction and ensure adequate ventilation. So the initial management is to open the airway and resecure it by reintubating. Once the airway is secured, provide 100% oxygen and assist with ventilation using positive pressure (often with PEEP) to improve oxygenation and recruit collapsed alveoli. Diuretics, steroids, or inhaled bronchodilators don’t address the underlying cause and aren’t first-line in this acute scenario; they may be considered later if specific indications arise, but they won’t promptly resolve the edema caused by the airway obstruction. With the airway cleared, edema typically improves as ventilation is restored and intrathoracic pressures normalize.
