Intraoperative pulmonary edema, what are the key management steps?

• A. Increase intravenous fluids and avoid diuresis
• B. Optimize hemodynamics, limit fluids, diuresis if indicated, and use positive pressure ventilation with PEEP
• C. Immediately terminate surgery and wake patient
• D. Administer high-dose vasopressors only

Answer: (B)

The main idea in managing intraoperative pulmonary edema is to support the heart and lungs while preventing further fluid buildup. The best approach combines optimizing the patient’s hemodynamics, restricting further fluid administration, removing excess fluid if appropriate, and ensuring adequate oxygenation with ventilation. Limiting fluids helps reduce ongoing edema formation, while diuresis, when there is true fluid overload, helps offload the left ventricle and decrease hydrostatic pressure in the pulmonary capillaries. Positive pressure ventilation with PEEP keeps alveoli open, improves oxygenation, and reduces shunt, which helps gas exchange despite the edema.

In practice, this means carefully balancing fluids and using diuretics if indicated, treating any hemodynamic instability so perfusion to vital organs is preserved, and employing PEEP to optimize oxygenation. Simply increasing fluids would worsen edema, and relying only on high-dose vasopressors without addressing fluid status won’t resolve the pulmonary edema. Terminating surgery or waking the patient isn't the immediate prerequisite unless there are other life-threatening issues, and those steps don’t directly target the edema management.
