Abstract
Fluorescein flowmetry measured changes in intestine blood flow were compared with changes detected by electromagnetic blood flowmetry and the 133X clearance. In 8 anesthetized pigs the blood flow in the superior mesenteric artery was reduced to 20-75% of basal flow as defined by electromagnetic flowmetry. The change in blood flow as calculated by fluorescein flowmetry correlated well with that obtained by electromagnetic blood flowmetry (r = 0.86) and 133Xe clearance technique (r = 0.94). Fluorescein flowmetry can be considered a quantitative method for measurements of a relative blood flow.
