BackgroundPregnancy poses a risk factor for respiratory infections due to hormonal changes, reduced tolerance to hypoxia, immunodeficiency, and increased susceptibility towards viral infections. Pregnant women might develop a broad spectrum of clinical conditions associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, from asymptomatic to potentially life-threatening complications. Critical respiratory failure associated with the progression of viral pneumonia is the most severe complication of the coronavirus disease (COVID-19). In some cases, it may require intubation and invasive mechanical ventilation.Case SeriesIn this case series, we evaluated the outcomes and clinical features of eight critically ill pregnant patients requiring invasive mechanical ventilation during treatment. The most commonly observed symptoms were fever at admission to the hospital, cough, difficulty breathing, and fatigue. Less frequently observed were sore throat and loss of smell and taste. All patients had anemia, and hypertension was the second most common comorbidity in pregnancy. Pregnant patients with lethal outcomes were older than those who recovered. They had higher body mass index values, more symptoms at admission, and higher C-reactive protein values and ferritin levels. Acute Respiratory Distress Syndrome (ARDS) was diagnosed in five cases, and none of these patients survived.ConclusionObesity, maternal age, and diagnosis of ARDS were most commonly observed in our group of patients with lethal outcomes. Preventive measurements, counseling, and enlightenment of potential risk factors, such as obesity, advanced maternal age, and pregnancy-related comorbidities, should be the cornerstones in crises such as COVID-19 when medical care and resources are limited or restricted.
