Abstract : Previous unidentified coronavirus was discovered in late December 2019, which known as COVID-19 disease was spread all over the world from Wuhan, China. Limited data are available about coronavirus disease 2019 during pregnancy. To find out the blood parameters and outcome of pregnancy in terms of neonate survival and birth weight among admitted COVID-19 positive pregnant women in a tertiary care hospital in Kolkata. A retrospective observational study was conducted at a designated COVID-19 Hospital in Kolkata. Data of 201 COVID-19 positive pregnant women admitted in Covid Antenatal Ward were analysed. Blood parameters like total count, C- Reactive Protein(CRP), Liver function test, sodium, potassium, urea, creatinine were assessed. Results were presented in tabular form in mean and percentage and test of significance was calculated. Mean age of 201 COVID-19 positive pregnant was 26.79 years with standard deviation of 4.94 years. The mean height was 1.59 meter and mean weight was 65.46 kg. 193 (96%) were asymptomatic and 186 (92.53%) mothers had no comorbidities. Commonest comorbidity found was pregnancy induced hypertension. COVID-19 biomarkers, mean of Ferritin, CRP and D-dimer was 4.49,18.69 and 2.37 respectively. Average total WBC count was 11826. 136 (41.3%) mothers had spontaneous onset of labour. 97 (48.3%) deliveries were vaginal delivery. 36 (17.91%) babies were delivered preterm. These observations strongly suggest the requirement of special care like provisions of radiant warmer, phototherapy that may be needed for the newborns of mothers with COVID-19.
