...M. Thollander; P.M. Hellström; B. Gazelius A small-bowel manometry tube was supplied with two single-fiber micro-probes, which recorded blood flow in the proximal small intestine by the laser-Doppler flowmetry (LDF) technique. In all experiments, saline was infused intravenously as control during...

... by means of a baby pressure gasket. Intestinal blood flow was measured by transit time flowmetry. Blood pressure was measured in a carotid artery and in veins of a closed loop of small intestine. The gasket pressure was increased stepwise in 10 mm Hg increments after which the intestinal venous pressure...

...E. Wahlberg; L. Enochsson To evaluate whether the microsphere method, including the necessary surgical procedures, for blood flow determination creates hemodynamic stress and a secondary reduction in small intestinal perfusion, we monitored the small intestinal perfusion with laser Doppler (LD...
