Hypofibrinogenemia in isolated traumatic brain injury in Indian patients.
Coagulation abnormalities are common in patients with head injuries. However, the effect of brain injury on fibrinogen levels has not been well studied prospectively to assess coagulation abnormalities in patients with moderate and severe head injuries and correlate these abnormalities with the neurologic outcome. Consecutive patients with moderate (Glasgow Comma Scale (GCS),9-12) and severe (GCS≤8) head injuries were the subjects of this pilot study, All patients had coagulation parameters, including plasma fibrinogen levels measured. Clinical and computed tomography (CT) scan findings and immediate clinical outcome were analyzed. Of the 100 patients enrolled, only seven (7%) patients had hypofibrinogenemia (fibrinogen ≤200 mg/dL). The head injury was moderate in two patients and severe in five patients. Fibrinogen levels showed a progressively increasing trend in four patients (three with severe head injuries and one with moderate head injury). CT scan revealed subdural hematoma in five patients; extradural hematoma in one; and subarachnoid hemorrhage in another patient. Of the seven patients, two patients died during hospital. Large-scale prospective studies are needed to assess the fibrinogen level in patients with head injury and its impact on outcome.
