{Reference Type}: Journal Article {Title}: Encephalic hemodynamic phases in subarachnoid hemorrhage: how to improve the protective effect in patient prognoses. {Author}: de Lima Oliveira M;de Azevedo DS;de Azevedo MK;de Carvalho Nogueira R;Teixeira MJ;Bor-Seng-Shu E; {Journal}: Neural Regen Res {Volume}: 10 {Issue}: 5 {Year}: May 2015 {Factor}: 6.058 {DOI}: 10.4103/1673-5374.156969 {Abstract}: Subarachnoid hemorrhage is frequently associated with poor prognoses. Three different hemodynamic phases were identified during subarachnoid hemorrhage: oligemia, hyperemia, and vasospasm. Each phase is associated with brain metabolic changes. In this review, we correlated the hemodynamic phases with brain metabolism and potential treatment options in the hopes of improving patient prognoses.
