The first study, conducted by the University of Texas, was presented during the annual conference of US anesthesiologists, CNN reports. Scientists analyzed all confirmed cases of COVID-19 in women who gave birth in a Texas hospital from March to September 2020. Among those who had symptoms of the disease, 58% of patients required emergency hospitalization. In the group of women who had asymptomatic coronavirus infection, 46% of women required emergency medical care.
In addition, these women were more often diagnosed with breech presentation and chronic inflammation, which negatively affected the condition of the newborns. These children were more likely to require oxygen support and hospitalization in an intensive care unit.
“Chronic inflammation is extremely dangerous for both the mother and the development of the fetus. It is a struggle for their survival, in which they pay a price, ”commented reproductive immunologist Gil Mor of Wayne University on the results of the study.
Women with COVID-19 are more likely to have cesarean sections than healthy women, but scientists have suggested that doctors recommended this measure for reasons of caution.
Another study was conducted by specialists at the Mayanei Hayeshua Medical Center in Israel. They studied the medical records of about 2.3 thousand pregnant women in the third trimester and also found significant differences in rates in expectant mothers with and without COVID-19.
A third of the infected women (33%) had symptoms of the disease, and it was in this group that the most severe complications were identified – the likelihood is 20% higher than in healthy women. Among pregnant women with asymptomatic infection, the risk of complications was 14% higher.
Patients with coronavirus patients were more likely to be diagnosed with gestational diabetes, their white blood cell counts were low, and they had an increased risk of heavy bleeding during childbirth. Their children were more likely to develop respiratory failure.
According to the authors of both scientific papers, all these results clearly demonstrate the need to vaccinate pregnant women. Note that in Russia, only expectant mothers from risk groups – with obesity, chronic diseases, immunodeficiency, etc. – can get vaccinated so far.
