RESUMEN
Acute respiratory syndrome caused by a novel coronavirus (SARS-CoV-2) in pregnant women can progress to a critical condition. In this paper, we present a case of a woman in the 28th week of gestation hospitalized due to respiratory insufficiency caused by COVID-19 infection and consequent bilateral pneumonia with development of severe acute respiratory distress syndrome. Noninvasive ventilation through a face mask was started but due to progression of respiratory insufficiency with high FiO2 and positive end expiratory pressure (PEEP), we decided to intubate the patient, after which obstetricians agreed to complete pregnancy by cesarean section. The clinical course was complicated by desaturation and bradycardia with recurring asystole which recovered after the use of atropine. The patient was increasingly difficult to mechanically ventilate on the PSIMV modality (tidal volume [TV] <200 mL). She was switched to ASV modality (TV up to a maximum of 350 mL, ASV 130%, PEEP 16 cm H2O, FiO2 100%, RR 25/min, pPeak 35 cm H2O, pPlateau 35 cm H2O), after which peripheral saturation recovered to 89%. Due to inadequate mechanical ventilation, the patient was transferred to Dr. Fran Mihaljevic University Hospital for Infectious Diseases in order to perform extracorporeal membrane oxygenation (ECMO). Owing to all of the measures taken, recovery followed after 13 days on ECMO.
