AbstractWe present a technique to measure pulmonary microvascular permeability for albumin in patients with multiple trauma by means of bronchoalveolar lavage (BAL). Routine laboratory tests for the analysis of BAL fluids are used. The results were clinically validated in 10 healthy volunteers and 12 patients with multiple trauma in a first prospective study. Additionally, another 11 severely traumatized and 24 less traumatized patients were evaluated in a second prospective study. Normal values (> 0.09 +/- 0.02), posttraumatic physiological ranges (< 0.35), and a "high risk" range (> 0.5) for pulmonary microvascular permeability for albumin were developed. There was a high correlation between the first posttraumatic values of pulmonary microvascular permeability and the required duration of intensive care treatment (r = 0.81), the duration of continuous mandatory ventilation (r = 0.78) and the mean lung injury score by Murray (r = 0.76). We conclude that the presented method is harmless and useful to describe the post-traumatic course of pulmonary microvascular permeability.
