Prediction of intestinal viability by intra-arterial dye injection: a simple test.
A vital dye solution injected intra-arterially stains only the viable parts in intestine of questionable viability. After various periods of ischemia, the viability of rat intestinal loops was assessed by three methods: on clinical basis; by detection of reactive hyperemia using an electronic thermometer; and by intra-arterial dye injection. The accuracy in viability prediction was 36, 69, and 84 per cent, respectively. The intraarterial dye injection method proved to be a simple, easy, and inexpensive way to accurately predict the viability of ischemic rat intestine.
