intravascular volume status in patients with moderate to severe covid-19: a case series

Coronavirus disease 2019 (covid-19) is a transmissible disease instigated by the coronavirus (sars-cov-2) which has been identify for few years. patients with covid-19 may present with hypovolemia due to vomiting, anorexia, or diarrhea. however, treatment guidelines recommend a “conservative” fluid administration strategy with dynamic measuring parameters to assess fluid response. since physical examination has a limited ability to predict volume status, other non-invasive methods such as point-of-care ultrasound (pocus) have been extensively used for this purpose in other diseases. in this case series, we describe intravascular volume status in patients with moderate to severe covid-19 as measured by inferior vena cava (ivc) calibre and distensibility.
