HEART RATE VARIABILITY IN ANESTHESIOLOGICAL PRACTICE

Abstract

Introduction. Patient safety in optimal working conditions of the surgeon is the main task of the anesthesiology service. Neurovegetative homeostasis is the goal of the anesthesiologist [9, 19, 20, 49]. Full-fledged examination, identification of clear contraindications, extended monitoring; ensure joint and effective work of the team. The depth of anesthesia depends on a significant number of exogenous and endogenous factors. Many methods are used to assess the function of the cardiovascular system, which contributes to the performance of safe anesthesia. Much depends on the effect of the drug, but the effect of afferent noc- and antinociceptive systems, which behave extremely unstable, may require significant adjustment of the standard calculated dose. The adequacy of the effect of drugs and technological means on vital functions during anesthesia is sometimes difficult to assess based on standard monitoring methods, which forces us to consider the effect of surgical stress on the ANS. Maintaining a balanced pharmacological protection of all vital systems, in particular, the autonomic nervous system (ANS) before, during and after anesthesia is of great practical interest [7, 10].
