[Effect of reflex regulation of premature labor on the status of the cholinergic system in the mother and newborn infant].

The cholinergic system (CS) has been assessed in 60 women with a premature onset of labor and their newborns. Labor was regulated using transcutaneous electroneurostimulation (TENS) in 40 of them. High-frequency TENS (100-120 Hz) was used for uterine contractility stimulation and low-frequency (30 Hz) was used for relaxation. A pattern of contractile uterine activity was elucidated which indicated beneficial effects of TENS on abnormal conditions in premature labor. A correlation was found out between the maternal and neonatal SC status.
