[Use of mathematical analysis of the cardiac rhythm in evaluation of the functional state of a patient in surgical interventions].
In 112 patients mathematical analysis of the cardiac rhythm indices and a biochemical investigation were effected during operative interventions with diverse types of endotracheal anesthesia. The correlation analysis of the cardiac rhythm parameters showed that at the most traumatic moment of the operation the synchronization of the functional links aimed at maintaining homeostasis was going up. Pharmacological block of adrenergic receptors results in weakening correlational interlinks. By analyzing the degree of synchronization marking functional links of the cardiac rhythm parameters that characterize the vegetative homeostasis it becomes possible to obtain information as to the level of the level of the adaptive-regulatory mechanisms tension and the correspondence of the depth of anesthesia to the seriousness of the operation trauma at different stages of surgery.
