Experimental Study of the Diagnostic Potentialities of Bioimpedance Measurement in Acute Intestinal Obstruction

Abstract

The dynamics of impedance values of the small and large intestine, parietal peritoneum, and greater omentum was analyzed during different periods of experimental acute intestinal obstruction. The impedance was below the normal, which indicated progressive microcirculatory disorders and necrosis of the intestinal wall. The histomorphological picture of healing of anastomoses created after resection of the intestine with consideration for bioimpedance values and of anastomoses created after resection of the intestine in a priori viable tissues virtually did not differ.

Bioimpedance measurements in dentistry to detect inflammation: numerical modelling and experimental results

“…When the passive electrode is moved along the mucosa, different impedance values will be measured; in particular, it is expected that the value will be lower when the current flows through the inflamed tissue, since it is richer in liquid content than the healthy one (hyperaemia and infiltration of the adjacent tissues are typical of the inflammatory process (Rodin et al 2013)) and, consequently, it can be passed by electrical current more easily.…”

“…The bioimpedance method is a technique widely applied to monitor the remodelling and changes in the organism under normal and pathological conditions (Rodin et al 2013). It is advantageous because it is minimally invasive and the necessary instrumentation is simple, ergonomic, non-invasive and relatively inexpensive (Belik and Belik 2007).…”
