Re-expansion pulmonary oedema: two case reports and review of the current literature

Re-expansion pulmonary oedema (RPE) is an uncommon complication that occurs when a collapsed lung suddenly re-expands, resulting in an osmotic shift of fluid from the blood vessels into the air spaces within the lungs. This condition can develop following thoracocentesis or intercostal chest drainage. We report two cases of RPE that developed after varying volumes of pleural drainage and at different times. Both patients responded well to non-invasive ventilation and hydrocortisone, making a full recovery. Early detection is crucial as RPE is associated with higher mortality rates, but a positive prognosis is attainable with prompt identification and intervention.
