Risk factors in severe head injuries

Area of Science:

• Neurosurgery
• Trauma Care
• Critical Care Medicine

Background:

• Severe head injuries represent a significant cause of mortality and long-term disability.
• Identifying risk factors is crucial for improving patient outcomes and guiding treatment strategies.

Purpose of the Study:

• To assess various pretraumatic, traumatic, and post-traumatic risk factors influencing mortality in patients with severe head injuries.
• To compare the prevalence of these risk factors between surviving and non-surviving patient groups.

Main Methods:

• A retrospective study of 472 consecutive patients with severe head injuries (Glasgow Coma Scale score ≤ 8).
• Patients were categorized into two groups: survivors (n=173) and non-survivors (n=299).
• Comparison of pretraumatic, traumatic, and post-traumatic risk factors between the two groups.

Main Results:

• Pretraumatic factors associated with increased mortality: advanced age, pre-existing disease.
• Traumatic factors: Glasgow Coma Scale score < 8, shock, abnormal pupillary response, motor deficits, extensor rigidity, lack of pain response, intracranial space-occupying lesions, and additional injuries.
• Post-traumatic factors: blood pressure alterations, biochemical abnormalities, hypoxia, endotracheal intubation, and mannitol infusion.

Conclusions:

• Multiple factors across different phases of care significantly impact mortality in severe head injury.
• Early identification and management of these risk factors are essential for improving patient survival rates.
