在心内直视手术中，为了解儿童脑电图（ＥＥＧ）与成人的差异，观察了２０例儿童和成人术中ＥＥＧ及颈动脉血流变化。结果显示：成人组鼻温与ＥＥＧ波率、额部波幅和枕部波幅有较好相关性（Ｐ＜０．００１）。颈动脉血管直径及颈动脉平均流速与ＥＥＧ波幅呈负性相关（Ｐ＜０．０５），平均动脉压与ＥＥＧ亦有较好的相关性（Ｐ＜０．００５）。在儿童组同样有以上的相关现象。其相关性在儿童组较成人组为明显。提示儿童ＥＥＧ对外部环境的变化较为敏感，变异性较大，特别是在体外循环手术中有其自身的变化规律，受血液动力学及温度的双重影响，与成人有较大的差异，特别是在体外循环手术中尤为明显。
In the open heart surgery, EEG and carotid artery blood flow changes in 20 children and adults were observed in order to understand the differences between children’s EEG and adults. The results showed that there was a good correlation between nasal temperature and EEG wave rate, forehead amplitude and occipital amplitude in adults (P <0.001). Carotid artery diameter and carotid mean flow velocity were negatively correlated with EEG amplitude (P <0.05), mean arterial pressure and EEG also had a good correlation (P <0.005). The same applies to the above group of children. The correlation was significant in children than in adults. It is suggested that children’s EEG is more sensitive to changes in the external environment and has greater variability, especially its own variation during cardiopulmonary bypass surgery. Due to the double influence of hemodynamics and temperature, children’s EEG are quite different from adults. In particular, In extracorporeal circulation surgery is particularly evident.
