- W2002106547 abstract "The effects of controlled hypotension induced by sodium nitroprusside (SNP) on central and splanchnic haemodynamics were studied in ten artificially ventilated dogs under neurolept anaesthesia. SNP was given intravenously as a continuous infusion in order to maintain a mean arterial blood pressure (MABP) of about 50 mmHg. Observations were made before (control) and at 20 and 60 min after the start of the SNP infusion. The mean SNP dosage was 13.7 micrograms X kg-1 X min-1. Systemic vascular resistance (SVR) decreased by 47%. After 20 min there was a 17% decrease in cardiac output, while the hepatic arterial blood flow was diminished by 39%, and portal venous blood flow by 16%. Cardiac output and portal venous blood flow tended to return towards control values at 60 min, while the hepatic arterial blood flow remained depressed. The total oxygen uptake was unaltered after 20 min, but slightly decreased after 60 min. There were no changes in hepatic or preportal tissue oxygen consumption, nor in hepatic lactate uptake. It is concluded that SNP-induced hypotension was achieved primarily by a profound reduction of SVR, and initially also by a slight decrease in cardiac output. Although splanchnic and hepatic blood flows decreased, there were no signs of hypoxia in the preportal tissues or in the liver." @default.
