Abstract

Since Wiggers’ study on the ‘Portal pressure gradients under experimental conditions, including haemorrhagic shock’ (Wiggers et al, 1946) a number of observations have been carried out to clarify the role of the small intestine in various types of shock. The small intestine is regarded as a shock organ (Fine 1967), since its circulation quickly deteriorates and thus contributes to the irreversibility of the shock. However, the autoregulation of the intestinal blood flow during reduced perfusion has been repeatedly verified (Johnson 1960; Haglund and Lundgren 1972). A similar circulatory reaction of the small intestine was also found by Haglund (1973) during haemorrhage. These autoregulatory reactions are considered to maintain constant pressure within the exchange vessels of the intestinal circulation (Svanvik 1973).
