BACKGROUND: Coronavirus disease 2019 (COVID-19) is associated acute respiratory distress syndrome that leads to intensive care unit admission and subsequent need of invasive ventilation. The aim of this study is to evaluate mortality rate and associated parameters among COVID 19 patients under invasive ventilation. METHODS: In this retrospective studies, COVID 19 patients referred to our center we evaluated. The data regarding demographic characteristics, comorbidities, biochemical and radiographic findings, need of invasive ventilation and mortality were collected and recorded for all the patients. Statistical analysis was performed to evaluate the risk of mortality in invasive ventilation patients relative to each risk factor or paraclinical or clinical feature. RESULTS: Among patients included in the study, 63 patients underwent invasive ventilation where 53 (84%) of these died. The mortality rate among invasive ventilation was significantly associated with advanced age, p = 0.006 whereas it was not significantly associated with smoking, gender, c-reactive protein, platelet count, hypertension, lymphopenia, leukopenia, creatinine kinase, addiction, blood urea nitrogen to creatinine ratio, malignancy, cough, fever, nausea, chronic obstructive pulmonary disease and erythrocyte sedimentation rate. CONCLUSIONS: The findings of our study indicate that advanced age can increase the risk of mortality in COVID 19 patients under invasive ventilation whereas, mortality among invasive ventilation patients is high, irrespective of their characteristic. Guidelines are therefore, required regarding the use of invasive ventilation among these patients.
