Abstract
Background : The mortality from acute respiratory distress syndrome(ARDS) in the late stage, which is characterized by progressive pulmonary fibroproliferation, is ${\geq}80%$. Although previous prospective trials failed to show a survival benefit of steroid therapy in early ARDS, recently, a few of reports have described the survival benefit of the long-term use of steroid in patients with late ARDS. In this study, we analyzed the effect of steroid therapy on patients with late ARDS retrospectively in a single. Medral intensive care unit (MICU). Methods : Over a 3-year period, the medical records of 48 ARDS patients who had been on mechanical ventilation more than 8 days were reviewed. 14 patients were treated by the long-term use of methylprednisolone and another 34 patients served as a control. Both groups were comparable regarding clinical and physiologic data lung injury score(LIS), multiple organ failure score, APACHE III and SAPS II score. Because steroid was instituted after 8 days of advanced mechanical ventilatory support in average, we arbitrarily defined the $8^{th}$ day of ARDS as first day of the study. Results : Initially, the groups had similar PF($PaO_2/FiO_2$) ratio, LIS, APACHE III and SAPS II score. By 7th day after the start of steroid therapy, there were significant improvements in PF ratio, LIS, APACHE III and SAPS II score. The mortality in the steroid treated group was significantly lower(42.9% vs 73.5%, p<0.05). Conclusion : Although the data of this study was retrospective and was not randomized, in order to improve the patient's outcomes, steroid therapy should be considered in late ARDS patients. However, prospective trials are needed to define the indication and the effect of steroid therapy in late ARDS.
