Redefining hypotension in traumatic brain injury

The association between admission systolic blood pressure and mortality in significant traumatic brain injury: A multi-centre cohort study

“…Alternatively Berry et al used logistic regression modelling to determine a cut-point for defining hypotension, identifying <110mmHg as the threshold providing optimal goodness of fit statistics. [40] This slightly lower threshold may stem from the data driven nature of the modelling, less rigorous control of confounding, or selection bias arising from complete case analyses.…”

Comparison of Revised Trauma Score Based on Intracranial Haemorrhage Volume among Head Injury Patients

“…Disruption of hemodynamic and intracranial pressure can cause secondary brain injury and may affect the hypothalamus in its role of producing catecholamine locally or systemically and the regulation of parasympathetic system which may disrupts blood pressure and respiratory system. Thus, a head injury with intracranial haemorrhage may impair the blood pressure, respiratory rate and consciousness (Martins et al, 2009;American College of Surgeons, 2012;Berry et al, 2012;Lee and Rincon, 2012;Takahashi et al, 2015).…”

Documento multidisciplinar de consenso sobre el manejo de la hemorragia masiva (documento HEMOMAS)

“…En pacientes con TCE, la presencia de hipotensión se asocia con un incremento de la mortalidad y peor pronóstico funcional 77,78 . Por lo tanto, en pacientes con TCE grave se recomienda mantener una PAS de al menos 110 mmHg o una PAM de al menos 80 mmHg 41 .…”

“…Recomendación 15 41,77,78 : En pacientes traumáticos con TCE grave se recomienda mantener una presión arterial sistólica de al menos 110 mmHg o una presión arterial media de al menos 80 mmHg (1C). ¿Cuándo se deben utilizar vasopresores en el contexto de una hemorragia masiva?…”
