Frequency of Meconium-stained Amniotic Fluid in COVID-positive Term Pregnancies and Perinatal Outcome

ABSTRACT

Aim: To know the frequency of meconium-stained amniotic fluid (MSAF) among COVID-positive term pregnant mothers and to know perinatal outcomes in these neonates. Materials and methods: A retrospective study was conducted of COVID-positive term pregnancies admitted to Vanivilas hospital, Bangalore Medical College, during the study period of 1 year. The study period was from 1st of July 2020 to 31st of June 2021. High-risk pregnancies that confound the occurrence of MSAF were excluded (obstetric risk factors and medical risk factors complicating pregnancy). Data were collected from medical records of patients and parturition register, which are cross-verified with operation theater records and neonatal intensive care unit (NICU) registers. Results: In total, 200 pregnant women were included in the study. About 65% were delivered by cesarean, 34.5% by the vaginal route, and one vacuum-assisted delivery. In total, 199 live births and one fresh stillbirth are reported. About, 26% had MSAF and 6.5% of newborns had meconium aspiration syndrome. Grade I, II, and III cases were 4.5%, 12.5%, and 9% respectively. Low appearance, pulse, grimace, activity, and respiration (APGAR) scores were correlating with the grade of MSAF, which is statistically significant. There were two neonatal deaths in grade III MSAF cases. Conclusion: The frequency of MSAF is increased among COVID-positive mothers, which translates to low APGAR scores and poor perinatal outcomes. Vigilant intrapartum care is recommended for these pregnancies to reduce the risk of poor neonatal outcomes. Clinical significance: The current study is undertaken to know if coronavirus disease-2019 (COVID-19) is associated with an increased frequency of MSAF among COVID-positive pregnant women. Finding MSAF has implications on operative delivery, cesarean rates, and perinatal outcome. There is a lack of studies about MSAF and perinatal outcomes in COVID-positive mothers. Evidence generated by this study helps to counsel the COVID-positive mothers and guides in the management of COVID-positive laboring women.
