SARS-CoV-2 pandemic and pregnancy in the El Pino Hospital: a descriptive study

INTRODUCTION: Compared to previous pandemics caused by other viruses, SARS-CoV-2 has affected the obstetric population in a smaller number, thus recording the medical history in patients with COVID 19 in our population became imperative. METHODOLOGY: A non-analytical, cross-sectional descriptive study was carried out in the maternity section of Hospital El Pino. PCR tests for SARS-CoV-2 were performed between April and June 2020 to all patients with: (1) symptoms suggestive of COVID 19, (2) a history of close contact or (3) requiring hospitalization regardless of motive. In them, demographic variables, clinical evolution were analysed and obstetric outcomes were estimated. RESULTS: 409 PCR were taken, raising a cumulative incidence of positivity of 19.7%. 55.6% (40 patients) were asymptomatic, 4.2% (9 patients) were close contact and 40.3% (29 patients) symptomatic. Within these patients, the majority turned out to be Chilean (79.2%) with a prevalence of HT and DM type 1 or 2 between 8-10%. The average of the gestational age at which the diagnosis was made was in the 3rd trimester and that of the moment of delivery was 37.1 weeks (+/- 3.9). The most common symptoms presented were cough, headache and myalgia, however, 7 patients required admission to the intensive care unit. In the monitoring stage of asyntomatic patients, 6.9% and 2.8% had symptoms on day 7 and 14 respectively. CONCLUSIONS: The SARS-CoV-2 pandemic has affected the obstetric population with no difference, with the majority presenting asymptomatic, fact which highlights the importance of universal screening when hospitalizing our users and avoiding intra-hospital transmission.
