prednisolone-hemisuccinate and Pulmonary-Edema

The influence of high-dose prednisolone on extravascular lung water (EVLW) was studied in a randomized trial in patients with noncardiac pulmonary edema. The patients were treated every 6 hours for 48 hours with 2 g of prednisolone-hemisuccinate or placebo. In the prednisolone-group (n = 7) EVLW decreased from 16.4 +/- 6.2 before to 11.8 +/- 5.1 ml/kg after treatment (p less than 0.05). Additionally alveolar-arterial oxygen gradient (AaDO2/FiO2), pulmonary vascular resistance and heart rate decreased, while arterial oxygen tension (PaO2/FiO2) and mean arterial pressure increased (p less than 0.05). In the placebo-group (n = 7) EVLW increased slightly from 17.5 +/- 3.1 before to 19.3 +/- 10.3 ml/kg after treatment. Additionally all other parameters did not change significantly in this group. Although no statistical significant difference was found between the two groups of treatment, a decrease in EVLW was observed in all prednisolone-treated patients, whereas a pronounced increase in EVLW was found in 3 placebo-treated patients. Probably, those patients would have benefited from high-dose prednisolone treatment. High-dose prednisolone reduced EVLW and improved hemodynamics and gas exchange in patients with noncardiac pulmonary edema, whereas placebo did not achieve comparable effects. Therefore, high-dose prednisolone appears beneficial in noncardiac pulmonary edema in respect of EVLW, hemodynamics, and gas exchange.
