Laser doppler for diagnosis of changes of microcirculation in the perioperal period in patients with acute adhesive obstruction of small gut

The article deals with changes in the amplitude-frequency spectrum of blood flow fluctuations in the perioperative period in patients with adhesive intestinal obstruction using computer diagnostics. To study the state of the microcirculatory bed and the mechanisms of its regulation, laser Doppler flowmetry was performed. Available results indicate significant changes at the level of the microcirculation system. Violation of blood circulation of tissues and decrease in body temperature at the end of surgery leads to hypoxia of organs and systems of the body, their dysfunction, and subsequently, insufficient functioning of the parenchymal organs and the development of complications.
