Myocardial ischemia in intestinal postischemic shock: the effect of hypoxemic reperfusion.

Objective: The circulatory shock following intestinal ischemia-reperfusion injury has been attributed to hypovolemia. The purpose of the current study is to clarify the pathophysiology of this type of shock and to test the hypothesis that hypoxemic compared with normoxemic reperfusion improves hemodynamics.

Design: Randomized animal study.
