Traumatic brain injuries in patients on antithrombotic agents carry significant morbidity. Initial therapy is centered around reversal of these agents. The thromboelastogram (TEG) maps the clotting cascade to guide reversal. A retrospective chart review was conducted for 118 patients presenting with a traumatic brain injury while on antithrombotics. Patients were divided between those who received a TEG on arrival and those who did not. The primary endpoint was overall mortality. Secondary endpoints included blood product utilization, and outcomes associated with specific novel anticoagulants. Mortality in the control group was 20.3 per cent compared with 18.5 per cent in the TEG group ( = 0.81). For less severe injuries, the control group mortality was 3.8 per cent and the TEG group mortality was 8.7 per cent ( = 0.64). For more severe injuries, mortality in the control TEG groups were 31.6 per cent and 25.8 per cent, respectively ( = 0.73). Blood product utilization was significantly lower in the TEG group ( = 0.002). Overall mortality was not significantly different between the groups. However, when stratified by severity of injury, mortality was reduced in the TEG-guided group in severely injured patients. Blood product utilization was significantly reduced with TEG-guided reversal. Trauma centers can improve the utilization of blood products in reversal of antithrombotics with the use of TEG.

Subdural hematoma as a complication of endoscopic third ventriculostomy in a pediatric patient: a case report and literature review.

Background: Subdural hematoma (SDH) typically occurs due to traumatic brain injury but can arise as a rare complication of procedures like endoscopic third ventriculostomy (ETV).
Case Presentation: We report an unusual case in a 9-year-old male with previous resection of a fourth-ventricle ependymoma at 2 years of age. Seven years post-surgery, he presented with worsening hydrocephalus and underwent ETV.
Background: Paroxysmal sympathetic hyperactivity (PSH) occurs with high prevalence among critically ill patients with traumatic brain injury (TBI) and is associated with worse outcomes. The PSH-Assessment Measure (PSH-AM) consists of a Clinical Features Scale and a diagnosis likelihood tool (DLT) intended to quantify the severity of sympathetically mediated symptoms and the likelihood that they are due to PSH, respectively, on a daily basis. Here, we aim to identify and explore the value of dynamic trends in the evolution of sympathetic hyperactivity following acute TBI using elements of the PSH-AM.

Acute kidney injury (AKI) is associated with adverse hospitalization. Previous studies have reported that an elevated triglyceride glucose (TyG) index is significantly associated with the development of AKI in patients with cardiovascular disease, as well as in those undergoing surgery; however, the potential of the TyG index to predict AKI following neurotrauma remains unclear. Patients diagnosed with traumatic brain injury (TBI) in Chinese tertiary hospitals between January 2014 and December 2023 were included in this retrospective study.

A wide range of acute brain injuries, including both traumatic and non-traumatic causes, can result in elevated intracranial pressure (ICP), which in turn can cause further secondary injury to the brain, initiating a vicious cascade of propagating injury. Elevated ICP is therefore a neurological injury that requires intensive monitoring and time-sensitive interventions. Patients at high risk for developing elevated ICP undergo placement of invasive ICP monitors including external ventricular drains, intraparenchymal ICP monitors, and lumbar drains.

Progressive hemorrhagic injury (PHI) is a frequent complication of traumatic brain injury (TBI). This study aims to investigate the impact of coagulation factors (platelet [PLT], prothrombin time [PT], activated partial thromboplastin time [aPTT], international normalized ratio , fibrinogen [Fg], D-dimer [Dd], and fibrin [Fib]) at admission and PHI development through a comprehensive systematic review and meta-analysis based on PRISMA 2020 guideline. Databases including PubMed, Scopus, Web of Science, and Embase were searched up to March 2024.
