Early post-traumatic acute respiratory distress syndrome and albumin excretion rate: a prospective evaluation of a 'point-of care' predictive test.
All patients sustaining major trauma exhibit increased capillary permeability, manifested as micro-albuminuria. Urinary albumin excretion rate (AER) measured on intensive care units (ICU) can predict early post-traumatic acute respiratory distress syndrome (ARDS). This prospective study sought to evaluate AER as a practical predictive test for early ARDS. ⋯ The test was performed most consistently in the middle 10 h of the study period. If intervention had been based on the 8 h data point result, 75% patients who had the test performed and later developed ARDS would have had intervention appropriately. In principle, testing for AER as a predictor of post-traumatic ARDS on ICU is feasible, however, this study has underlined the challenges of introducing new concepts into the ICU environment.
