The state of the vegetative nervous system in patients with gonarthrosis for surgical treatment before and after surgical treatment

Aim. Analyzing the vegetative tensity of organism» functional systems before and after surgical treatment of elderly patients with metabolic-and-dystrophic gonarthrosis. Methods. The evaluation of vegetative homeostasis, reactivity of the vegetative nervous system by the data of variation pulsometry («REAN-POLY» RGPA-6/12, Taganrog) in 60 patients with gonarthrosis at the age of 50-72 years and the disease duration — 9+1.5 years before and after surgical treatment: total tunnelization (Group I), tunnelization with osteotomy of leg bones for correction of limb biomechanical axis (Group II), treatment-and-diagnostic arthroscopy (Group III). Results. The reduction of the level of hypoxia tolerance and the decrease of the processes of general adaptation one month after surgery in Group I was registered in 40% of patients. As for patients of Group II, by the end of the period of fixation with the llizarov device — in 50%. As for those of Group III after arthroscopy — in 10% of patients. Among the patients whose 1С / 1С calculated parameter after surgical treatment was registered 10.0 before treatment in 70% of cases. At rest, marked vagotonia was registered with hypersympathicotonic reaction to orthotest, as well as with sharp decrease of the proportion of second-order slow waves while transition to standing position (VLF proportion
