AbstractThis study analyzed the predictable factors of outcome such as neuro-parameters and systemic complications to elucidate the indications for therapeutic hypothermia. In our institute, 35 patients with severe head injury (Glasgow Coma Scale 3-7) were treated with mild hypothermia therapy (33 degrees-35 degrees C). Twenty-two of these 35 patients underwent complete neuromonitoring and outcome assessments by Glasgow Outcome Scale (GOS) at three months after injury. GOS of hypothermia group was significantly better than another patient group which was treated without mild hypothermia therapy. The hypothermia group was divided into two groups: good outcome (GOOD) (good recovery or moderate disability; n = 9, 40.9%) and poor outcome (POOR) (severe disability, vegetative state, or death; n = 13, 59.1%). The mean age (mean 30.2 years, range 9-46) was significantly lower in GOOD than in POOR (mean 45.2 years, range 17-62). Patients aged over 50 years had poor outcome. CPP was significantly higher in GOOD during hypothermia. All patients with thrombocytopenia had poor outcome. Hypothermia therapy can improve outcome in patients with traumatic brain injury who are younger than 50 years old, without severe brain damage, and if improvement of cerebral perfusion is expected. Systemic complications must be prevented as far as possible by combination with other therapies.
