Introducción: La insuficiencia respiratoria aguda durante el embarazo no es una causa frecuente de ingreso a la unidad de cuidados intensivos, pero sí puede generar alta mortalidad. Las adaptaciones que sufre el organismo en muchos de sus sistemas biológicos durante el embarazo, condicionan cambios en el diagnóstico y tratamiento de este trastorno en comparación con la población general. Objetivo: Realizar una revisión bibliográfica sobre el tema y resumir los principales aspectos fisiológicos a tener en cuenta por el personal de salud en contacto con esta población, con el fin de realizar un adecuado abordaje de los casos.

Importance: The effect of high-flow oxygen therapy vs conventional oxygen therapy has not been established in the setting of severe COVID-19.

Objective: To determine the effect of high-flow oxygen therapy through a nasal cannula compared with conventional oxygen therapy on need for endotracheal intubation and clinical recovery in severe COVID-19.

Design, Setting, And Participants: Randomized, open-label clinical trial conducted in emergency and intensive care units in 3 hospitals in Colombia.

The efficacy and safety of ertapenem, 1 g once a day, for the treatment of community-acquired pneumonia (CAP) requiring parenteral therapy were compared with those of ceftriaxone, 1 g once a day, in 866 hospitalized adults randomized in two prospective, double-blind, multicentre studies. Patients were stratified according to Pneumonia Severity Index (< or = 3 or >3) or age (< or = 65 or >65 years). After > or = 3 days of parenteral antimicrobial therapy, patients who had clinically improved could be switched to oral co-amoxiclav.

In a double-blind, multicenter trial, 502 patients hospitalized with community-acquired pneumonia were randomized to receive therapy with either ertapenem or ceftriaxone (for each, 1 g given intravenously once daily). After a minimum of 3 days, therapy could be switched to oral amoxicillin-clavulanate. The median duration of intravenously administered therapy for the 383 clinically evaluable patients was 4 days for both treatment groups; 345 patients (90.
