Popis: Objective: To evaluate the possible effects of a combination of systemic nitric oxide synthesis inhibition (to increase mean arterial blood pressure) and nitric oxide inhalation (to decrease pulmonary vascular pressure) in porcine endotoxin shock. Design: Prospective trial. Setting: Laboratory at a large University medical center. Subjects: Ten pathogen-free pigs weighing 19 to 25 kg. Interventions: After surgical preparation, all pigs received a continuous infusion of Escherichia coli lipopolysaccharide endotoxin (15 μg/kg/hr) for 2 hrs. After 1 hr of endotoxemia, nitric oxide inhalation (50 parts per million) and N G -nitro-L-arginine infusion (50 mg/kg/hr) were initiated in six pigs. Four pigs served as controls and received only a lipopolysaccharide infusion. Measurements and Main Results: N G -nitro-L-arginine infusion and nitric oxide inhalation prevented the further decrease in mean arterial blood pressure seen in the control pigs (p
