Intravenous iloprost increases mesenteric blood flow in experimental acute nonocclusive mesenteric ischemia

Abstract

Iloprost infusion increased SMA blood flow by 60% in this model of nonocclusive mesenteric ischemia (from 168 +/- 41 to 269 +/- 76 mL/min; p <.05). The effect of iloprost infusion was more prominent after the tamponade (422 +/- 87 mL/min in the iloprost group vs. 232 +/- 111 mL/min in the control group; p <.05). Increased mesenteric perfusion decreased intestinal mucosal hypercarbia, leading to improvement of intramucosal pH.
