RESUMEN
Objective The objective of this study was to evaluate the relationship between unilateral spatial neglect (USN) and haemoglobin (Hb) level in acute phase of stroke. Method Cross-sectional study was performed after right hemisphere ischemic stroke. Independent variable: Hb level (mg/dL); Outcome: USN; Potential confounding factors: Age, National Institutes of Health Stroke Scale (NIHSS), and glycaemia (mg/dL); Characterization variables were obtained from electronic medical records, Hb, mean corpuscular volume (MCV) and glycaemia by laboratory exams, and USN by cancellation and bisection tasks. The relationship between Hb and USN was assessed by Spearman correlation and linear regression model. Results 40 individuals were evaluated; it was observed that the higher the Hb level, the better the USN test performance, with the two being negatively correlated. There was no significant correlation between VCM level and USN performance. Conclusion Low hemoglobin levels may indicate a worse performance in USN cancellation and bissection tests in acute phase of stroke. .
Objetivo O objetivo do estudo foi avaliar a relação entre a negligência espacial unilateral (NEU) e hemoglobina (Hb) na fase aguda do acidente vascular cerebral (AVC). Método Foi realizado estudo transversal em pacientes com AVC de hemisfério direito dentro das primeiras 48 horas do ictus. Variáveis independentes: nível de Hb (mg/dL); Desfecho: NEU; Fatores potenciais de confundimento: Idade, National Institutes of Health Stroke Scale (NIHSS) e glicemia (mg/dL); A caracterização das variáveis foram obtidas por meio de prontuários eletrônicos, Hb e glicemia por exames laboratoriais, e NEU por meio do Line Cancellation (LCT), Star Cancelation (SCT), e Line Bisection Tasks (LBT). Resultados 40 indivíduos foram avaliados e foi observado que quanto maior os níveis de Hb, melhor o desempenho nos testes de NEU, demonstrando correlação negativa entre eles. Conclusão Níveis baixos de hemoglobina podem indicar pior desempenho nos testes de NEU na fase aguda do AVC. .
