Abstract

INTRODUCTION: Angiotensin II (Ang II) is a potential vasopressor treatment for hypotensive hyperdynamic sepsis. However, unlike other vasopressors, its systemic, regional blood flow and renal functional effects in hypotensive hyperdynamic sepsis have not been investigated. METHODS: We performed an experimental randomised placebo-controlled animal study. We induced hyperdynamic sepsis by the intravenous administration of live E. coli in conscious ewes after chronic instrumentation with flow probes around the aorta and the renal, mesenteric, coronary and iliac arteries. We allocated animals to either placebo or angiotensin II infusion titrated to maintain baseline blood pressure. RESULTS: Hype..
