Coagulation Parameters and Risk of Progressive Hemorrhagic Injury after Traumatic Brain Injury: A Systematic Review and Meta-Analysis

Abstract EN

Intracranial hemorrhage (ICH) after traumatic brain injury (TBI) commonly increases in size and coagulopathy has been implicated in such progression.

Our aim is to perform a meta-analysis to assess their relationship.

Cochrane library, PubMed, and EMBASE were searched for literatures.

Pooled effect sizes and 95% confidential intervals (CIs) were calculated using random-effects model.

We included six studies, involving 1700 participants with 540 progressive hemorrhagic injuries (PHIs).

Our findings indicate that PT, D-dimer level, and INR value are positively associated with the risk of PHI.

Higher level of PLT and Fg seemed to suggest a lower risk of PHI.

Among these parameters, higher D-dimer level and INR value would possess more powerful strength in predicting PHI.
