Peculiarities of Change in Hemodynamic Indicators in Persons With Different Types of Vegetative Nervous System at Dental Reception

Abstract

In the dental clinic GAUZ KSP No. 10, Volgograd examined 80 patients who applied for dental care at the age of 25-30 years. Before and after the dental appointment, blood pressure - systolic (SD), diastolic (DD), pulse rate (HR), and respiratory rate (RR) were measured. The indirect method of Star (1954) was used to calculate the minute volume of blood circulation (MVC), according to the formula of F. Poiseuille (1839), peripheral vascular resistance (PSS) was determined, according to the formula of N.N. Savitsky (1974) calculated the average hemodynamic pressure of the SRS. The vegetative status was calculated according to the values of the Kerdo vegetative index (VI). The patients were divided into 3 groups, depending on the type of ANS, sympathotonics in 36 patients (including 25 men and 11 women), normotonics 18 people (8 men and 10 women), vagotonics 26 people (5 men and 21 women). During a dental appointment, patients with a symptomatic type of autonomic regulation had high blood pressure (SD, DD), PD, and heart rate, IOC, SRS. With the vagotonic and normotonic type of autonomic regulation, DM and DD were within the normal range, but before taking the numbers were higher than after it. Analysis of hemodynamic parameters in patients during a visit to the dentist made it possible to identify the features of regulation and mechanisms of tension of adaptive capabilities depending on the type of the autonomic nervous system.
