Abstract
Background: despite the severity of infection with influenza virus, little has been reported about its presence in pregnant women. Objective: to communicate our experience on influenza virus H1N1 in pregnant women. Methods: we conducted a retrospective cohort study on 16 hospitalized patients with diagnosis of pregnancy and probable or confirmed case of infection with H1N1 influenza virus. Suspected case: sudden onset of respiratory infectious process, in 2009, in Mexico City. All cases underwent the fast detection test and subsequently confirmation by PCR test. Discharge criteria: clinical improvement, PaO(2) above 60 mm Hg and absence of bilateral consolidation on chest radiographs. Severity criteria: type I respiratory failure (PaO(2) < 50 mm Hg) who required mechanical ventilatory support, radiographic pattern compatible with multisegmental pneumonia and PaO(2)/FiO(2) < 200 mm Hg. Results: the pregnant patient mortality was 4.25%. The average age was 25.8 years, with 24.13 weeks of gestation with 5.6 days average of hospital stay. The main co-morbidity was obesity. Conclusions: the fatal cases were those with longer time of evolution and late diagnosis.
