Method for Determining Microcirculatory Hemodynamics by Laser Speckle Interferometry in Small Animals

Method for Determining Microcirculatory Hemodynamics by Laser Speckle Interferometry in Small Animals:

We performed experimental evaluation of various positions (ear, paw, and tail) of the of dynamic light scattering sensor of near-infrared laser radiation (840 nm) using speckle interferometry in rats. Dynamic monitoring of the reactions to prolonged ultrasound exposure (7 days) showed that the base of the tail is most suitable for this purpose. Additionally, analysis of microcirculation parameters on the surface of skin autograft was performed. The method of analysis of hemodynamics in humans was adapted for animals.
