HORMON ADAPTATION OF THE NEWBORNS FROM MULTIPLE PREGNANCY AT THE FIRST WEEK OF THEIR LIFE
In this article the authors studied the level of hormones (cortisol, TSH, Т3 и Т4) at birth and on 3-4 day after birth in the newborn from multiple pregnancies. It was revealed that the first fetus had significantly higher level of cortisol and significantly low TSH at birth and on 3-4 day of life than the second fetus. Twins with weight discordance has cortisol level difference to compare with non-discordant twins. Intrauterine growth retardation (IUGR) associated with higher cortisol and T3 in IUGR, the higher T3 level persisted until 3-4 days of life. The association was found between hormones level and mode of birth and type of anesthesia. The authors come to the conclusion that it is necessary to conduct randomized controlled studies
