Covid-19 durante el embarazo: revisión rápida y metaanálisis / Covid-19 during pregnancy: a rapid review and meta-analysis

RESUMEN

Resumen Objetivo: Resumir la evidencia científica sobre efectos maternos y neonatales del Covid-19 durante el embarazo. Material y métodos Se realizó una revisión rápida Cochrane y un metaanálisis de proporciones y razones de momios (RM). Resultados: Los eventos maternos más comunes fueron la ventilación mecánica invasiva y admisión a la unidad de cuidados intensivos (UCI); las complicaciones del embarazo fueron el sufrimiento fetal y la ruptura prematura de membranas; las comorbilidades fueron la obesidad y el asma. Las cesáreas indicadas por Covid-19 fueron frecuentes (51%). Los eventos neonatales comunes fueron bajo peso y prematuridad; se identificaron neonatos SARS-CoV-2 positivos (14%). Las embarazadas con Covid-19 experimentaron más cesáreas (RM combinada=6.7) y partos pretérmino (RM combinada=2.9); los neonatos experimentaron más admisiones a la UCI neonatal (RM combinada=5.9). Conclusión: La evidencia sobre los efectos adversos del Covid-19 durante el embarazo es limitada. No se pueden descartar riesgos a la salud del binomio, particularmente debido a las cesáreas y prematuridad.

ABSTRACT

Abstract Objective: To summarize the scientific evidence of adverse health effects of Covid-19 during pregnancy. Materials and methods We conducted a Cochrane rapid review. Meta-analysis of proportions and odds ratios (OR) were performed. Results: Frequent maternal events included invasive mechanic ventilation and admission to the intensive care unit (ICU); pregnancy complications were fetal distress and premature rupture of membranes; common comorbidities were obesity and asthma. Deliveries by cesarean section (C-section) due to Covid-19 were frequent (51%). The most frequent neonatal outcomes were low birthweight and prematurity; we identified cases of SARS-CoV-2 positive neonates (14%). Pregnant women with Covid-19 were more likely to deliver by C-section (pooled OR=6.7) and prematurely (pooled OR=2.9); neonates were more likely to be admitted to the neonatal ICU (pooled OR=5.9). Conclusion: The available evidence on Covid-19 during pregnancy is limited. Therefore, we cannot disregard adverse health effects on the mother-child pair, particularly those related to C-sections and premature deliveries.
