Electroencephalography (EEG) recording techniques in early premature babies are not very different from those used for full-term neonates. Here, we emphasise the most important points: asepsis precautions, full knowledge of the clinical data and drug therapies, fundamental role of a well-trained technician in supervising the EEG recording and monitoring the baby. We discuss the best electrode positions, the most informative montages, and their standardisation between neurophysiological laboratories. Artefact detection constitutes an important aspect of EEG signal analysis in preterm babies of less than 30 weeks. It is obviously necessary to discriminate between meaningful information and artefacts. The complexity of the signal in neonates makes artefact detection difficult. We present some characteristic features and describe some methods for eliminating them. We underline the positive aspect of some artefacts and their clinical use. We emphasise the crucial role of the technicians.
早期早产儿的脑电图（EEG）记录技术与足月儿使用的技术并没有太大差异。在此，我们强调最重要的几点：无菌预防措施、对临床数据和药物治疗的充分了解、训练有素的技术人员在监督EEG记录和监测婴儿方面的重要作用。我们讨论最佳电极位置、最具信息量的导联组合以及它们在神经生理实验室之间的标准化。伪迹检测是孕周小于30周早产儿EEG信号分析的一个重要方面。区分有意义的信息和伪迹显然是必要的。新生儿信号的复杂性使得伪迹检测变得困难。我们介绍一些特征并描述一些消除它们的方法。我们强调一些伪迹的积极方面及其临床用途。我们强调技术人员的关键作用。
