Bradicardia relativa como marcador de mortalidad en hipertensos con trauma craneoencefálico en el Hospital Teodoro Maldonado Carbo durante el 2013 – 2021.

Abstract

Background: Traumatic brain injury is defined as the alteration of brain function due to an external physical force. There are no precise and updated numbers on this issue in our country. Abnormal systolic blood pressure plays a very important role in injury after severe traumatic brain injury, and the relationship between hypotension and increased mortality in patients with TBI is well established. Relative bradycardia is a common finding and has also been associated with high mortality. However, there are no studies in our environment that establish a relationship between relative bradycardia and hypertensive patients. Objective: Establish the relationship between relative bradycardia and mortality in hypertensive patients with traumatic brain injury. Methodology: Quantitative, observational, analytical, retrospective, and cross-sectional study that involves patients who were treated at the Teodoro Maldonado Carbo Specialty Hospital during the period from 2013 to 2021. A multivariate analysis was carried out where the OR was calculated for certain variables of interest. Results and conclusion: In total, 181 patients met the inclusion criteria. TBI was more frequent in males (89%), the average age was 49.5 years, the most frequent mechanism of trauma was falls (49.7%) and subarachnoid hemorrhage (23.8%) was the most reported injury in CT scans. Hospital stay was most frequent in the range of 1 day to 1 month (73.5%). Hypertensive patients with relative bradycardia (HR 60-90) were 4.62 times more likely to die than tachycardic patients (HR>90) (95% CI: 1.04-20.49, p= 0.04).
