[Behavior of pO2 on rabbit small intestine serosa, measured with the Clark electrode in different models of intestinal ischemia].

The pO2 on the surface of the small intestine serosa was measured on an isolated small intestine loop of the rabbit after synchronistic arterial and venous ligature of the mesenterium, after synchronistic arterial starvation and venous ligature, and after torsion of the mesenterium. The measurements of the pO2 were carried out by means of a Clark-electrode. Different periods for the decrease of the pO2 to zero Torr were shown in the different models of intestinal ischemia. Only the difference between the synchronistic arterial and venous ligature and torsion was statistically significant.
