Abstract:Introduction Our goal was to assess the effects of titration of a norepinephrine infusion to increasing levels of mean arterial pressure (MAP) on sublingual microcirculation.

“…Algunos estudios han documentado buenos resultado clínicos en pacientes con shock séptico en quienes se ha empleado como meta hemodinámica una PAM ≥ 65 mmHg [29][30][31][32] . No obstante, algunos pacientes con hipertensión arterial crónica pueden requerir mayores niveles de PAM para asegurar una adecuada presión de perfusión a los diferentes órganos, lo que debe ser determinado en forma individualizada y evaluado a través del comportamiento de los diferentes marcadores de oxigenación tisular.…”

“…Se ha observado que los pacientes que mejoran precozmente su patrón microcirculatorio tienen una mayor posibilidad de supervivencia 75,76 . No obstante, la respuesta de la microcirculación a manipulaciones hemodiná-micas es compleja y depende mucho de su estado basal o del tipo de intervención 32,[77][78][79][80] . Un estudio prospectivo aleatorio que comparó una infusión de nitroglicerina intravenosa contra placebo durante la reanimación inicial de pacientes con sepsis severa o shock séptico, no demostró mejoría de la microcirculación sublingual evaluada por SDF.…”

“…In addition, there is clearly room for individual variability. A recent study examining the effect of varying perfusion pressure with norepinephrine on responses of the sublingual microcirculation found no effect on the population as a whole, but a fair amount of variation in individual responses, with patients reaching maximal perfusion at different mean arterial pressures [9].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
