[Relationship between the state of the autonomic nervous system and nociceptive reactivity during preoperative emotional stress].

Using a complex of techniques, the state of autonomic nervous system, nociceptive reactivity, emotional status and endocrine reactions have been studied in 108 patients with preoperative emotional stress. It has been established that the immediate preoperative period in young patients is characterized by predominance of sympathetic nervous system tone associated with hypercortisolemia and high nociceptive reactivity. Sedative effect of premedication with tranquilizers is poorly realized.

[The dependence of sensory perceptions on the predominance of parasympathicotonia or sympathicotonia during preoperative psychoemotional stress].

Low tactile and pain thresholds and high Kerdo index were observed in patients with sympathicotonia predominance during preoperative emotional stress. Low Kerdo index and high tactile and pain thresholds were observed in patients with parasympathicotonia predominance during preoperative psychoemotional stress.
