Abstract:
Accepted methods to evaluate intestinal vascularity intraoperatively include standard clinical criteria (SCC), doppler ultrasound (DUS), and intravenous fluorescein (FLF). A combination of methods is often used to overcome disadvantages of individual techniques. Assessment of intestinal vascularity by FLF was compared to SCC, DUS, and pulse oximetry (POX) in segments of intestine demonstrating arterial, venous and arteriovenous occlusion, to determine if POX might supplement the assessment of intestinal vascularity. POX uses a commercially available instrument to assess tissue oxygenation and arterial flow, and is rapid, reproducible, and noninvasive. POX appears to be a superior technique when compared to SCC and DUS.

Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
