Исходное состояние и динамика показателей сердечного ритма у недоношенных новорожденных в периоде ранней постнатальной адаптации

Abstract

Изучено исходное функциональное состояние и закономерности ранней постнатальной адаптации автономной нервной системы недоношенных новорождённых. Вариабельность сердечного ритма определялась методами вариационной пульсографии по Р. М. Баевскому и анализа частотного спектра кардиоритмограммы. Установлено, что для недоношенных новорожденных в раннем постнатальном онтогенезе характерна выраженная симпатикотония («гиперсимпатикотония»), которая обеспечивается онтогенетически более древним периферическим аппаратом симпатического отдела автономной нервной системы и компенсаторной нейрогуморальной гиперстимуляцией её морфологически незрелого центрального аппарата, что, с одной стороны, обеспечивает протекание трофических процессов в незрелом организме, а с другой - создает ситуацию «риска декомпенсации» автономной нервной системы, особенно в возрасте 6-10 дней.

Initial functional status and regularities of early postnatal adaptation of autonomous nervous system inpremature newborns were studied. Cardiac rhythm variability was determined by variation pulsography (R. M. Baevsky technique) and cardiorhythmogram frequency spectrum analysis. It was stated that premature newborns in early postnatal ontogenesis were characterized by manifested sympathicotony ("hypersympathicotony"). It was ontogenetically assured by more ancient peripheral apparatus of sympathetic part of autonomous nervous system and by compensatory neurohumoral hyperstimulation of its morphologically immature central apparatus; this fact both provided the elapsing of trophic processes in premature organism and created the situation of "decompensation risk" of autonomous nervous system especially in the newborns aged 6-10 days.
