FRIDAY, July 2, 2021 (HealthDay News) – Maternal gestational diabetes (GDM) may increase the risk of fetal hypoxia, according to a study published online in Acta Diabetologica on June 21.
Mikko Tarvonen from the University of Helsinki in Finland and colleagues investigated whether there was a connection between the ZigZag pattern (FHR baseline amplitude changes of> 25 beats per minute with a duration of two to 30 minutes) and asphyxia-related neonatal outcomes in GDM pregnancies . Intrapartum cardiotocographic (CTG) patterns were recorded in a cohort of 5,150 single births. Zigzag patterns, saltatory patterns, late decelerations, episodes of tachycardia and bradycardia, reduced variability, and changes in uterine tachysystole CTG were examined in women with GDM, women with normal oral glucose tolerance test (OGTT), and women without OGTT.
The researchers found that 12.1 percent of the women were diagnosed with GDM and 79.9 and 8.0 percent of the women were normal and OGTT was not done. Compared to those without GDM, those with GDM had an increased risk of hypoxia-related zigzag patterns (odds ratio, 1.94) and late slowing of FHR (odds ratio, 1.65), as well as an increased risk of fetal asphyxia ( Odds Ratio, 6.64.). ).
“Hopefully the new findings will improve childbirth safety – both in terms of preventing fetal hypoxia and in terms of the mother’s sense of security,” Tarvonen said in a statement.
