Quantitative measurement of blood flow in various areas of small and large intestine

Abstract

A direct method is presented for the continuous quantitative measurement of blood flow in various areas of the small and large intestine. The mean blood flows of the duodenum, jejunum, ileum and descending colon were 1.39, 0.98, 0.83 and 0.73 ml/gm wet tissue/min. The cannulation of the intestinal artery to any intestinal area does not appear to interfere with the blood flow or pressure to the area. With proper precautions, a preparation will last 5 hours before measurable changes in blood flow and pressure occur.
