Negative-Pressure Pulmonary Oedema

  • Seen in the early postoperative period
  • Due to forced inspiration in the presence of upper airway obstruction (e.g. from laryngospasm after extubation)
  • After relief of laryngospasm, patients develop clinical and radiological features of pulmonary oedema
  • Typically resolves over the course of a few hours with supportive care
  • Cardiogenic pulmonary oedema should be excluded by clinical assessment, ECG and echocardiography
