The content of gas transmitters in umbilical cord blood and blood of newborns born to mothers with preeclampsia

Abstract

To assess endothelial function in the newborns born to mothers with preeclampsia and without preeclampsia the scientists assessed the content of nitricoxide and hydrogen sulfide in the umbilical and venous blood of these children. The main group consisted of 80 women with moderate preeclampsia and their80 newborns; the control group included 50 children born to women without preeclampsia. The authors studied the content of nitric oxide by determining the totalnitrates and nitrites (NOx), hydrogen sulfide in mixed cord blood collected within 30 minutes after delivery, and venous blood taken from newborns on the 1-3rd day of life. Umbilical cord blood demonstrated no significant differences in the content of NO xand hydrogen sulfide in newborns of the main and control groups. However, in general, the study of umbilical cord blood revealed a relationship between the concentration of hydrogen sulfide and the possibility of developing intraventricular hemorrhagein a newborn of the main and control groups. In the venous blood there was a significant increase in the content of NOx and hydrogen sulfide in newborns born to mothers with preeclampsia. It may cause vasodilation asa compensatory reaction of the body during the period of postnatal adaptation of the child’s body, aimed at life support.
