| Abstract: | AIM: When studying intestinal blood flow (IBF) using radiolabeled erythrocytes in the rabbit intestinal volvulus model, we also evaluated whether a pulse oxymeter (POX) could be used for the measurement of intestinal blood flow. METHODS: IBF was measured with radiolabeled erythrocytes and POX in the rabbit intestinal volvulus model. The study was performed on 3 groups: 1) baseline, 2) volvulus, 3) volvulus plus devolvulus. RESULTS: The POX and scintigraphic measurements were in correlation and showed that IBF stopped for 6 hours following volvulus. IBF was significantly decreased in the volvulus plus devolvulus group compared to the baseline group (p < 0.01). IBF measured with POX correlated with scintigraphic measurements. CONCLUSION: POX is useful for the measurement of IBF and thus may be a cheap and reliable alternative to other intestinal blood flow measurement methods. |
