聴性脳幹反応（BAER）による重症脳障害患者の予後評価

Assessment of outcome prediction in severe brain damage patients with brainstem auditory evoked response

　聴性脳幹反応（BAER）およびGlasg（Glasgow Coma Scale（G．C．S．）scoreを指標に急性期重症脳障害患者の予後判定を試みた．

　対象はいずれもG．C．S．が10点以下（平均5.6）を呈したもので，その内訳は破裂脳動脈瘤14例，頭部外傷6例，高血圧性脳内出血9例，脳腫瘍内出血1例の計30症例である．

Patients with various neurologicaldisease resulting in severe brain damage andhaving Glasgow Coma Scale (G.C.S.) score ofless than ten (mean 5.6) were studied withbrainstem auditory evoked response (BAER)during the first few days of onset. Amongthem were subarachnoid hemorrhage, head in-jury, intracerebral hemorrhage, pontine hemor-rhage, intraventricular hemorrhage and bleedingtumor. BAERs were graded into four levelsfrom one (normal) to four (most abnormal).Outcomes were categorized through the Glas-gow Outcome Scale. Comparison of the resultsbetween BAER and G.C.S. as predictors of out-come was quite similar.
