Identification of abnormal pupil dilation velocity as a biomarker of cerebral injury in neurocritically ill patients

Abstract: Objetivo Calcular as velocidades médias da dilatação de pupila para classificar a gravidade da lesão derivada da escala de coma de Glasgow, estratificada por variáveis de confusão. Métodos Neste estudo, analisaram-se 68.813 exames das pupilas para determinar a velocidade normal de dilatação em 3.595 pacientes com lesão cerebral leve (13 - 15), moderada (9 - 12) ou grave (3 - 8), segundo a escala de coma de Glasgow. As variáveis idade, sexo, raça, tamanho da pupila, temp… Show more

“…Swelling or bleeding in or around the brain due to TBI can increase the pressure within the skull, causing damage to the brain or restrict blood supply. Hypothermia can be effective in reducing intracranial pressure, but it is not clear whether it improves survival or brain function (17,18), 37 . Prophylactic hypothermia made no difference to favorable neurologic outcome at 6 months.…”
