Blood flow in different areas of the gastrointestinal tract in the anesthetized dog

Abstract

Radioactive rubidium (⁸⁶Rb) acts as the almost ideal tracer and gives accurate measurements of regional blood flow. In dogs weighing between 10 and 20 kg and anesthetized with sodium pentobarbital, blood was distributed to the various gastrointestinal organs as follows: esophagus 29.5 ml/min 100 g; stomach 52.3 ml/min 100 g; gall bladder 35.8 ml/min 100 g; duodenum 111.1 ml/min 100 g; pancreas 65.2 ml/min 100 g; jejunum and ileum 99.5 ml/min 100 g; and colon 123.6 ml/min 100 g.
