Treatment with sivelestat sodium of acute respiratory distress syndrome induced by chemical pneumonitis: A report of three cases

Inhalation of acid fumes and aspiration liquid substances or gastric contents may not initiate dyspnea within several hours after exposure but result in delayed onset alveolar edema. The present report presents three cases inhalation chemical that resulted acute respiratory distress syndrome (ARDS). Due to different underlying reasons, patients developed ARDS resulting from pneumonitis pulmonary infection. From with dyspnea, dry rales could be heard both lungs, <92% percutaneous oxygen saturation at room air. All were treated using a high‑flow nasal cannula sivelestat sodium. Oxygenation gradually improved the discharged without adverse events. These suggest early treatment sodium improve clinical outcomes ARDS.
