Abstract


Severe head Injury result in primary and secondary brain damage. The secondary brain damage produces a more worse effect than
the primary one. Therefore, the process of the secondary brain damage should be prevented in order to obtain a maximum result of
patient management. The difficulty is to make sure, whether the secondary brain damage is already very bad or, on the other hand, is
still in a positive condition, causing patient management to have a good result. The prognostic decision, is the most important thing in
patient management. The objective of this research was to find an accurate prognostic factor which is simple and non invasive for severe
head injury for each time lapse, 24, 48, 72 and 120 hours after the brain damage which had caused the head injury. The installation of
an intracranial pressure (ICP) monitor for the first 24 hours, after the head injury, followed by taking a cerebrospinal fluid sample for
BDNF examination at the first 24 hours, 48 hours, 72 hours and 120 hours as well. Enzyme Linked Immunosorbent Assay was used to
determine BDNF. Each subject was assessed by Glasgow Outcome Scale classification, three months after the injury. The result of this
research was that BDNF at 48 hours after head injury showed a significant difference (p < 0.05) between good and bad Glasgow Outcome
Scale classification. Thus, it can be concluded that patients with an increase in BDNF (>6.16 pg/mL) 48 hours after head injury, may
have a good prognosis.
