ABSTRACT
INTRODUCTION:
Traumatic brain injury (TBI)-associated coagulopathy significantly influences survival outcomes in patients with multiple injuries. Severe TBI can potentially affect systemic hemostasis due to coagulopathy; however, there is limited evidence regarding whether the risk of hemorrhage increases in patients with pelvic fractures complicated with TBI. Therefore, through multivariable analysis, we aimed to examine the association between severe TBI and increased blood transfusion requirements in patients with pelvic fractures. MATERIALS ANDMETHODS:
This retrospective observational study was conducted at a tertiary care facility in Japan. Patients aged 16 years or older with pelvic fractures who were admitted to our intensive care unit between April 2014 and December 2021 were included in the analysis. The patients were categorized into no to mild and severe TBI groups according to whether the Head Abbreviated Injury Scale (AIS) score was 3 or higher. The primary outcome was the number of red blood cell (RBC) units transfused within 24 h after arrival at the hospital. The primary outcome was analyzed using univariable and multivariable linear regression analyses. The covariates used for the multivariable linear regression analysis were age, sex, antithrombotic therapy, mechanism of injury, Pelvic AIS score, and extravasation on contrast-enhanced computed tomography on admission.RESULTS:
We identified 315 eligible patients (221 and 94 in the no to mild and severe TBI groups, respectively). In the univariable analysis, the RBC transfusion volume within 24 h after arrival was significantly higher in the severe TBI group than in the no to mild TBI group (2.53-unit increase; 95 % confidence interval [CI] 0.46-4.61). However, in the multivariable analysis, no statistically significant association was detected between severe TBI and the RBC transfusion volume within 24 h after arrival at the hospital (0.87-unit increase; 95 % CI -1.11-2.85).CONCLUSIONS:
Concomitant severe TBI was not associated with increased RBC transfusion volumes in patients with pelvic fractures on multivariable analysis.Palabras clave
