[Functional condition of autonomic nervous system in children with chronic gastroduodenal pathology]

A study was made of autonomic nervous system function in 125 children with chronic gastroduodenal pathology. Of these, 37 children presented with peptic ulcer, 36 with erosive processes occurring in the gastroduodenal area, and 52 with superficial gastroduodenitis. The status of the autonomic nervous system was evaluated according to the initial vegetative tone, vegetative reactivity, and vegetative supply of the activity in carrying out cardiointervalography and the clinoorthostatic test. The predominance of the normotensive initial vegetative tone, the combination of the sympatheticotonic vegetative tone with erosive ulcerous lesions of the gastroduodenal area and a grave disease course were demonstrated as was the predominance of hypersympatheticotonic vegetative reactivity. In carrying out the clinoorthostatic test, the given children's group showed 2 main types of the tuning of the regulatory system, corresponding with normal and excess vegetative supply of the activity.
