COVID-19 is a disease that has a varied clinical spectrum from asymptomatic to severe symptoms. Because it is an emerging disease, the continuous contribution of clinical and epidemiological data is convenient for public health. The objective of this research work was to describe the clinical and laboratory characteristics of patients with COVID-19 in intensive care in a Venezuelan region for which there is no information in this regard. The study, a short report, was descriptive and prospective of patients with COVID-19 hospitalized in an intensive care unit, whose sample was 27 patients in whom the following were described: age, sex, clinical parameters, pathological history, laboratory results. , radiological tests and hospitalization data. The findings reveal that the most affected were 52.8±18.6 years old, with a body mass index of 23.1±4.3, diabetic and hypertensive, with abnormal liver enzymes and parameters such as: LDH, CRP, Bun, D-dimer and glycemia, SaO2 of 70 % and in tachypnea. It is concluded that advanced age is an important risk factor, as well as diabetes mellitus and arterial hypertension. That the SaO2 is less than 90 % in those with poor clinical evolution, with a predominance of the bilateral ground glass radiological pattern and alteration of liver enzymes (towards an increase), as well as for LDH, CRP, fibrinogen, BUN, D-dimer , glycemia and leukocytes.
