RESUMEN
BACKGROUND: Sepsis-associated brain dysfunction is a frequent disorder in septic patients and has a multifactorial pathophysiology. Cholinergic pathways and brainstem dysfunction may result in pupillary alterations. The aim of this study was to evaluate whether early assessment of the Neurological Pupil Index (NPiTM) derived from an automated pupillometry could predict mortality in critically ill septic patients. METHODS: Retrospective cohort study of adult critically ill septic patients admitted to the intensive care unit of a University Hospital; patients with acute or known brain damage were excluded. Patients' severity was assessed by the daily Sequential Organ Failure Assessment Score and the SOFA
