脑电功率谱在脑外伤诊断中的价值

APPLICATION OF ELECTROENCEPHALOGRAM POWER SPECTRUM OF DIAGNOSIS OF HEAD INJURY

本文用计算机处理的脑电功率谱(APS)指标δ+θ/α+β及θ/β观察脑外伤病人和正常人的改变,结果表明,脑外伤病人的δ+θ/α+β及θ/β功率比明显高于正常人。证明APS对脑外伤病人的诊断和预后有重要价值。

Sixty patients with head injury and 50 normal controls were studied with the APS criteria δ+ θ/ α+ β and θ/ β which were dealt by a computer. The results stowed that δ+ θ/ α+ β and θ/ β were signi-ficantly higher in the patients than that in the controls(P<0.005). We studied changes in 24 patients injured in head and found that δ+ θ/ α+βlowered as the condition improved, and that thers were no δ+ θ/ α+β changes in the patients who had no improvement. Our studies indicats APS is valuable to the early diagnosis and prognosis of the head injury.
