We investigated the contribution of alpha- and beta-adrenergic pathways to catecholamine-induced pulmonary edema and the role of pleural effusion in preventing alveolar edema. Female Sprague-Dawley rats received continuous intravenous infusion of norepinephrine and of separate alpha- or beta-adrenergic stimulation over 6-24 h. We performed heart catheterization in vivo and excised post mortem lung tissue for histological analysis. Interleukin (IL)-6 and total protein concentrations were determined in serum, pleural fluid (PF) and bronchoalveolar lavage fluid. alpha-Adrenergic treatment increased right ventricular systolic pressure (RVSP) and total peripheral resistance (TPR) and caused severe alveolar edema associated with IL-6 activation in serum and diffuse pulmonary inflammation. PF amounts were moderate (0.9+/-0.2 ml). beta-Adrenergic stimulation also increased RVSP but decreased TPR. Interstitial but not alveolar edema and focal inflammation without IL-6 activation developed. Large PF amounts (6.2+/-1.5 ml) occurred which were considered to prevent alveolar edema. We conclude that both alpha- and beta-adrenergic stimulation contribute to pulmonary fluid shifts in rats, but alpha-adrenergic pathways cause more acute and more severe lung injury than beta-adrenergic mechanisms.
