VIELMA O., Sebastián et al. Premature delivery in COVID-19 patients at San Juan de Dios Hospital. Rev. chil. obstet. ginecol. [online]. 2020, vol.85, suppl.1, pp.S59-S66. ISSN 0048-766X.

Introduction and Objectives:

The SARS-CoV-2 pandemic has affected pregnant women with different clinical manifestations, one of them premature labor. The objective of this study is to characterize the pregnant patients with COVID-19 who had their delivery and to determine the risk of preterm delivery in this group compared to those who did not have the disease at the Maternity Department in San Juan de Dios Hospital, and determine what the rate of premature delivery is.


Retrospective observational cohort study where pregnant patients were included between April and June of 2020 at the Maternity Department in San Juan de Dios Hospital. Patients who had their delivery were selected and demographic and medical data, obstetric history, information regarding delivery, newborn history and characteristics of COVID-19 disease were evaluated.


Among COVID-19 positives, a 16.9% had premature labor, reaching a nonsignificant OR 1.79 (0.76-3.84 95% CI) compared to those COVID-19 negative. Among those with severe COVID-19, all had preterm birth, with a significant OR (>=7.84 95% CI) compared to those with mild symptoms or COVID-19 negative. 10.1% of newborns of COVID-19 mothers required neonatal resuscitation, while, in the negative ones it was 5.5%.


Among COVID-19 patients, a trend towards increased risk of preterm birth was observed compared to those without the disease, with the increased risk being significant in those with symptoms and even more significant if they had severe disease.
