Postoperative pulmonary edema

Last edited: 4/15/2026

Overview

Postoperative pulmonary edema (PPE) is a serious complication characterized by fluid accumulation in the lungs following surgical procedures, often exacerbated by large volume infusions or compromised physiological mechanisms 1.

Diagnosis

  • Clinical signs include dyspnea, tachypnea, hypoxemia, and crackles on auscultation 2.
  • Diagnostic imaging: Chest X-ray often reveals bilateral infiltrates 2.
  • Pulmonary function tests may show restrictive pattern or reduced diffusion capacity 2.

    • Management

  • Fluid restriction and diuretic therapy (e.g., furosemide) to manage fluid overload 1.
  • Mechanical ventilation support if respiratory failure occurs 2.
  • Monitoring and management of underlying causes, such as anesthetic toxicity 1.

    • Special Populations

  • Elderly: Higher risk due to decreased physiological reserve; vigilant monitoring and fluid management crucial 1.
  • Comorbidities: Patients with pre-existing cardiac conditions are at increased risk; tailored anesthetic and fluid management strategies recommended 1.

    • Key Recommendations

  • Identify and closely monitor high-risk patients for fluid overload and anesthetic toxicity preoperatively and intraoperatively (Evidence: Expert opinion) 1.
  • Implement fluid restriction and consider diuretic therapy in managing postoperative pulmonary edema (Evidence: Expert opinion) 1.
  • Provide vigilant respiratory support, including mechanical ventilation if necessary, for patients with respiratory failure secondary to PPE (Evidence: Expert opinion) 2.
