Renal and systemic hemodynamic responses to intravenous infusion of leukotriene C4 in the rat.
We studied the systemic and renal hemodynamic effects of leukotriene C4 (2 micrograms/kg per min for 5 minutes, iv) in the rat. During the period of its infusion, leukotriene C4 produced a significant elevation of mean arterial pressure and reductions in cardiac output and renal blood flow, as measured by electromagnetic flow probes. These effects were abolished by FPL55712 , a putative antagon...
متن کامل[Transition from intravenous to subcutaneous prostacyclin in pulmonary hypertension].
Treatment of arterial pulmonary hypertension with epoprostenol (intravenous prostacyclin) improves survival and quality of life, but the need for an implanted central venous catheter is associated with frequent complications, that often (as in the case of infection or dislodgment) are serious and require catheter replacement. Treprostinil is a prostacyclin analogue suitable for continuous subcu...
متن کاملSubcutaneous to intravenous prostacyclin analog transition in pulmonary hypertension.
INTRODUCTION Prostacyclin analogs are Food and Drug Administration-approved therapies for the treatment of pulmonary arterial hypertension and can be administered by inhalational, intravenous (IV), or subcutaneous (SQ) routes. Because there are limited data to guide the transition between SQ to IV prostacyclin analogs, we describe our experience. METHODS We performed a retrospective review of...
متن کاملCardiac output in four-, five-, and six-week-old broilers, and hemodynamic responses to intravenous injections of epinephrine.
Female broilers were evaluated at 4, 5, and 6 wk of age (1.2, 1.8, and 2.3 kg BW, respectively) to assess changes in cardiac output and related hemodynamics associated with BW gain, and to evaluate cardiopulmonary hemodynamic adjustments occurring secondary to i.v. injections of epinephrine (0.1 mg/ kg BW). Cardiac output increased with BW (253, 348, and 434 mL/min at 4, 5, and 6 wk, respective...
متن کاملRenal responses of normal and preascitic broilers to systemic hypotension induced by unilateral pulmonary artery occlusion.
During the pathophysiological progression of pulmonary hypertension syndrome (PHS; ascites), broilers concurrently develop systemic hypotension (low mean systemic arterial pressure) that may initiate renal retention of water and solute, contributing to fluid accumulation in the abdominal cavity (ascites). In male Single Comb White Leghorns, glomerular filtration is autoregulated over a systemic...
