| Abstract |
|
We define acute respiratory failure(ARF) as present whenever the ratio of arterial oxygen tension (PaO2) and inspired oxygen concentrarion(FiO2) is below the normal predicted range for the patient's age and/or the arterial carbon dioxide tension(PaCO2) is above 45 in the absence of respiratory compention for metabolic alkalosis. Adult respiratory distress syndrome(ARDS) which is associated with shock, trauma, infection, inhalation of toxic gas, aspiration of gastric content and drugs etc, first received wide-spread attention in 1967. ARDS is a descriptive term that is characterized by a combination of refractory hypoxemia and severly decreased lung compliance. Numerous specific incidents or illnesses may be complicated by, or associated with ARDS. Early diagnosis and improvement in physiological therapy including PEEP therapy have been successful in treating the early and mild episodes of ARDS.
This report describes three cases of ARF following anesthesia and reviews the literature. |
