Introduction:

SARS-CoV-2 infection is a health problem worldwide. It’s highly important to identify new clinical manifestations, mainly the serious form of the disease, because it produces severe acute respiratory syndrome, which is responsible for millions of deaths. Several studies associate the serious form of SARS-CoV-2 with high obesity and immune suppression.

Objective:

to analyze body mass index (BMI) with prolonged invasive mechanical ventilation (IMV) in patients with SARS-CoV-2 from Intensive Care Unit.

Material and methods:

retrospective correlational and observational study.

Results:

a significant association between obesity grade (BMI > 30 kg/m2) and mortality was found in patients diagnosed with SARS-CoV-2 under invasive mechanical ventilation through more than 20 days. Obesity grade I (p = 0.001) and II (p = 0.008) showed higher influence on patient’s mortality with induced mechanical ventilation.

Conclusions:

patients with obesity (BMI > 30 kg/m2), mainly grades I and II showed higher mortality and risk of prolonged invasive mechanical ventilation, so it is important to diagnose and apply early and proper treatment to this type of patients in order to reduce mortality.
