Influence of the relative insulin deficiency of the mother on the functional state of the central nervous system of the fetus in the third trimester of pregnancy

85 women from the 28-th to the 40-th week of pregnancy were examined.
Nineteen women with impaired glucose tolerance in the third trimester of pregnancy formed the control group. Forty women had gestational diabetes and 26 insulin­ independent diabetes. The data reveal negative influence of relative insulin insufficiency in expectant mothers on formation of the central neural system of the fetus that is displayed in shortening or even absence of quiet state phase, prolongation of the intermediate state, decrease of motor-cardiac reflex. The intensity of these disturbances depends upon the diabetes type and the rate ofits compensation.
