impact of COVID-19 on maternal, fetal, and neonatal characteristics
In the present study, researchers reported the fetal and maternal
characteristics of pregnant women diagnosed with COVID-19 and neonatal and maternal
characteristics of neonates having early onset COVID-19. The team conducted a
prospective cohort study at a tertiary referral center in North India. The
study included all pregnant women displaying severe to critical SARS-CoV-2
infection and neonates with early onset COVID-19. The pregnant women were
tested for COVID-19 during admission to the referral centre via reverse
transcriptase-polymerase chain reaction (RT-PCR).
The women were screened for SARS-CoV-2 infection for severe or critical
disease as per the definitions by the Chinese Centre for Disease Control and
Prevention. The severe infection was characterized by dyspnea, blood oxygen
saturation of 93% or less in room air, and respiratory rate of more than 30
per minute. The critical disease was characterized by septic shock, respiratory
failure, and/or multiple organ failure or dysfunction.
The team obtained data related to demography, known comorbidities,
symptomatology, gestation period, pregnancy-associated complications,
information regarding investigations and management, hospital stay duration,
intensive care unit (ICU) stay, the requirement of external ventilation, and
pregnancy outcomes such as neonatal and maternal outcome recorded from the time
of hospital admission to either discharge or hospital death.
All neonates born to SARS-CoV-2-infected mothers were tested for
COVID-19 using throat and nasopharyngeal samples. Neonatal and maternal characteristics
such as Apgar score, neonatal ICU (NICU) admission, birth weight, neonatal
morbidities, respiratory support, and mortality were recorded for neonates
having early-onset COVID-19. The team also noted any SARS-CoV-2 presence on
different maternal samples such as amniotic fluid, placental swabs, cord blood,
and cervical and vaginal swabs obtained at the time of birth to assess the
possibility of viral transmission from mother to child.
