RESUMO
INTRODUCTION: We analysed the neurological complications of patients with severe SARS-CoV-2 infection who required intensive care unit (ICU) admission. PATIENTS AND METHODS: We conducted a retrospective, observational, descriptive study of consecutive patients admitted to the ICU due to severe respiratory symptoms secondary to SARS-CoV-2 infection between 1 April and 1 June 2020. RESULTS: We included 30 patients with neurological symptoms; 21 were men (72.40%), and mean age (standard deviation [SD]) was 57.41 years (11.61). The mean duration of ICU stay was 18.83 days (14.33). The neurological conditions recorded were acute confusional syndrome in 28 patients (93.33%), neuromuscular disease in 15 (50%), headache in 5 (16.66%), cerebrovascular disease in 4 (13.33%), and encephalopathies/encephalitis in 4 (13.33%). CSF analysis results were normal in 6 patients (20%). Brain MRI or head CT showed alterations in 20 patients (66.6%). EEG was performed in all patients (100%), with 8 (26.66%) showing abnormal findings. In 5 of the 15 patients with clinical myopathy, diagnosis was confirmed with electroneuromyography. We found a correlation between older age and duration of ICU stay (P=.002; 95%CI: 4.032-6.022; OR: 3,594). CONCLUSIONS: Severe COVID-19 mainly affects men, as observed in other series. Half of our patients presented acute myopathy, and almost all patients left the ICU with acute confusional syndrome, which fully resolved; no correlation was found with EEG or neuroimaging findings. Older age is associated with longer ICU stay.

RESUMO
When working in healthcare centers in developing countries where diagnostic resources are limited, clinical skills are of considerable importance. This study presents the diagnostic tools available in resource-poor areas. Anamnesis and physical examination are key components for reaching a correct diagnosis. The laboratory has at its disposal hemograms, basic blood chemistry and urinalysis. The available basic microbiological tests are the study of fresh feces, smears for malaria, direct smears for bacilli in sputum and Gram staining of clinical exudates. Basic radiography of the chest, abdomen, bones and soft tissues are of considerable usefulness but are not available in all centers. Ultrasonography can be of considerable usefulness due to its simplicity and versatility. The diagnosis in low resource conditions should sharpen our clinical skills and should be supported by the use of additional basic tests.
