Abstract
Blood flow to the splanchnic area is reduced in most forms of shock. In certain forms, such as following cardiac tamponade, the reduction in splanchnic blood flow is disproportionally great while in others, such as sepsis, blood flow rather changes in parallel with cardiac index. The renin-angiotensin axis seems to be important in situations with a disproportionate splanchnic vasoconstriction [1]. Blood flow distribution within the gastro-intestinal tract i.e. the distribution of blood to the various layers of the gut, is changing during ischemia and sepsis to ensure that a larger proportion of flow is directed to the mucosa [2]. Still, shock of various forms as well as regional ischemia of other causes rapidly lead to the development of characteristic injuries of the splanchnic organs. This injury is for the hollow viscera at least initially confined to the superficial layer of the mucosa (Table 1) [3]. This chapter will mainly deal with the pathogenesis and the implications of such injury in the stomach and the small intestine.
