Features of neurological and psychomotoral development of premature children born by IVF and naturally

Abstract

Introduction.The use of in vitro fertilization methods plays an important role in overcoming the childlessness of families, but they must be combined with the success of nursing premature newborns to increase the effectiveness of assisted reproductive technologies. Children with very or extremely low body weight are at risk of increased rates of infant mortality and disability. The study of the state of health and the analysis of the psychomotor/neurological status of such children is extremely important due to the study of the possibilities of reducing the frequency of negative outcomes.Aim.A study during the first 3 years of neurological/psychomotor development in premature infants diagnosed with extremely low/very low body weight, born as a result of in vitro fertilization and naturally.Materials and methods.Studies of neurological/psychomotor development in premature infants have been carried out. The study included 189 infants diagnosed with prematurity at birth. The studies were carried out on the basis of the intensive care unit and the department of prematurity and neonatal pathology at the Republican Children’s Clinical Hospital (Ufa). Then, for 3 years, regular observation was carried out in the follow-up room in the same institution. Dynamic assessment of neurological and psychomotor status was performed using the Clinical Adaptive Test and Clinical linguistic and auditory milestone scales, as well as Gross Motor testing.Results and discussion. It was found that the incidence of neurological morbidity related to developmental delay is significantly higher in children born as a result of in vitro fertilization than in those conceived naturally. Thus, the number of children lagging behind in speech development at the age of up to 1 year is 59.1/59.6 and 52.1/52.3% when diagnosed with very low and extremely low body weight.Conclusion.The dynamics of the average coefficient of speech development in children conceived artificially did not reach (less than 75) normal values by the age of 3, and in the control group, the coefficient of speech development was normalized. There is no significant difference between very low and extremely low body weight children.
