Cerebral hemodynamic patterns in patients with head trauma and their relationship with mortality

Abstract

Background: mortality from severe head trauma is high and is due to the intracranial hemodynamic disorders that it causes. Objective: to determine the patterns of cerebral blood flow in the patient with head trauma and its relationship with mortality. Methods: descriptive, cross-sectional study carried out in the Arnaldo Milían Castro Clinical-Surgical Hospital Serious Care Units, Santa Clara, Villa Clara province, from 2004 to 2007 and from 2018 to 2020. The transcranial Doppler ultrasound was performed in 82 patients, in the first 24 hours after admission, after hemodynamic and respiratory stability. The Glasgow coma scale variables, cerebral blood flow patterns and mortality were determined. The information was processed using the statistical program SPSS / PC version 15 for Windows, statistical processing with univariate analysis was applied.Results: 82 patients were studied, with mortality of 37.8% of the total; the highest fatality occurred among patients older than 65 years (60%) (p = 0.01). The Glasgow coma scale of 8 or less points included 67 patients, with a mortality of 43% (p = 0.00). The cerebral ischemic pattern was the most diagnosed (43.9%) with a mortality of 74% (p = 0.03).Conclusions: the ischemic blood flow pattern is the most frequent and has a significant relationship with mortality. The Glasgow coma scale has a significant relationship with the mortality of patients with head trauma.
