Abstract

The results of experimental study of possibility to monitor the micro-vascular blood flow in superficial tissues of various organs with the use of endoscope-based full-field speckle correlometer are presented. The blood microcirculation monitoring was carried out in the course of the laparotomy of abdominal cavity of laboratory animals (rats). Transfer of laser light to the area of interest and scattered radiation from the probed zone to the detector (CMOS camera) was carried out via fiber-optic bundles of endoscopic system. Microscopic hemodynamics was analyzed for small intestine, liver, spleen, kidney, and pancreas under different conditions (normal state, provocated peritonitis and ischemia, administration of vasodilative agents such as papaverine, lidocaine). The prospects and problems of internal monitoring of microvascular flow in laboratory and clinical conditions are discussed.
