This study was undertaken to evaluate the usefulness of the EEG in neonates with intracranial hemorrhage (ICH) and to correlate the EEG with clinical findings and the CT-scan. Thirty-eight infants with intraventricular hemorrhage (IVH) and/or subarachnoid hemorrhage (SAH) had EEG examinations. Repetitive sharp waves were present in IVH (48%) and also seen in SAH (33%). They did not differentiate between IVH and SAH, nor were they related to the grade of IVH. The repetitive character of these wave forms suggest that it may be a type of seizure discharge. The value of the EEG in neonatal ICH lies not in the diagnosis of ICH and its extend. This can be done much better with CT-scan and ultrasound. But the EEG is valuable in the recognition of electrical seizure activity which should lead to early anticonvulsive therapy. Depressed background EEG activity was seen in all non-survivors and in all children with major neurological damage. Normal background activity in spite of seizure discharge was favorable prognostic criterion. The prognosis depends on the gestational age, clinical findings and morphological changes. The EEG reflects the actual cerebral function and can add to a more differentiated prognostic evaluation.
本研究旨在评估脑电图（EEG）在颅内出血（ICH）新生儿中的应用价值，并将EEG与临床发现及CT扫描结果进行关联。38例患有脑室内出血（IVH）和/或蛛网膜下腔出血（SAH）的婴儿接受了EEG检查。重复尖波出现在IVH患儿中（48%），也见于SAH患儿（33%）。它们无法区分IVH和SAH，也与IVH的分级无关。这些波形的重复性表明其可能是一种癫痫放电类型。EEG在新生儿ICH中的价值不在于ICH的诊断及其范围，这通过CT扫描和超声能做得更好。但EEG在识别癫痫电活动方面具有价值，这应能促使早期进行抗惊厥治疗。所有死亡患儿及所有有严重神经损伤的儿童均出现EEG背景活动抑制。尽管有癫痫放电但背景活动正常是良好的预后标准。预后取决于胎龄、临床发现和形态学改变。EEG反映了实际的脑功能，可有助于进行更具差异性的预后评估。
