SMALL BOWEL TRANSIT TIME OF WATER SOLUBLE IODINATED CONTRAST MEDIUM AND BARIUM SULFATE IN CATS WITH SIMULATED SURGICAL ACUTE ABDOMEN

The transit time of barium sulfate and hypaque through the small bowel was compared in: (a) normal cats; (b) the same cats medicated with probanthine (a drug which produces a simulated adynamic ileus); (c) the same cats 24 hours after abdominal exploration; (d) the same cats with induced mechanical obstruction or perforation of the small bowel; and (e) a small group of cats in which both mechanical small bowel obstruction and perforation were surgically effected.

The small bowel transit time for hypaque was shorter than for barium in most instances, with or without adynamic ileus produced by probanthine. The transit time of barium sulfate 24 hours after abdominal exploration was unchanged compared with that in the same intact animal. Twenty-four hours after abdominal explorations, however, transit times with hypaque in half of the examined cats were longer than those of the control study in the same animal.
