Abstract
A number of factors, including Glasgow coma scale (GCS) score, age, pupillary response and size, hypoxia, hyperthermia, and high intracranial pressure, may play an important role in predicting the outcome of traumatic brain injury. Eight hundred forty-six cases of severe traumatic brain injury (GCS < or = 8) were analyzed retrospectively to clarify the effects of multiple factors on the prognosis of patients. At 1 year after injury, the outcomes in these cases were as follows: good recovery, 31.56%; moderate disability, 14.07%; severe disability 24.35%; vegetative status, 0.59%; and death, 29.43%. The outcomes were strongly correlated (p < 0.05) with GCS score, age, pupillary response and size, hypoxia, hyperthermia, and high intracranial pressure (ICP). These findings indicate that prevention of hypoxia, control of high ICP, and prevention of hyperthermia may be useful means for improving the outcome of patients with severe head injury.
