Coagulation disorders following acute head injury

Area of Science:

• Neurotrauma
• Hematology
• Critical Care Medicine

Background:

• Acute head injury can trigger complex coagulation disorders.
• Disseminated intravascular coagulation (DIC) is a critical complication with high mortality.
• Understanding prognostic factors is vital for managing these patients.

Purpose of the Study:

• To investigate coagulation disorders in patients with acute head injury.
• To identify the incidence and types of coagulation abnormalities.
• To evaluate factors influencing patient survival and prognosis.

Main Methods:

• Prospective investigation of 100 patients with acute head injury.
• Analysis of coagulation parameters including activated partial thromboplastin time (APTT) and fibrinogen.
• Multivariate analysis to determine prognostic indicators.

Main Results:

• 24% of patients developed disseminated intravascular coagulation (DIC), most common in subdural hematomas.
• Mortality rate for patients with DIC was 58%.
• Serum fibrin-fibrinogen degradation product (FDP) levels correlated with tissue damage severity.
• APTT was the strongest predictor of survival in all patients; serum fibrinogen was critical for DIC patients.

Conclusions:

• Coagulation disorders, particularly DIC, are significant complications of acute head injury.
• Early identification of DIC and monitoring of APTT and fibrinogen are crucial for improving patient outcomes.
• Prognosis is strongly linked to specific coagulation markers, highlighting the need for targeted interventions.
