摘　　要：目的　探讨老年人连续硬膜外复合全麻下胸腔手术时数量化脑电图与麻醉深度的关系。　方法　 30例老年人胸腔手术 ,均为连续硬膜外复合静吸全麻 ,根据吸入异氟醚浓度不同分为肺泡气最低有效浓度 (MAC)0 .6 ( 组 )和 MAC 1.0 ( 组 )两组 ,观察术前、诱导前、插管后、切皮进胸探查、进胸后 30 ,6 0 min以及术毕时循环和脑电图边缘频率 (SEF)、中位频率 (MF)、比率 (δR)和双频谱指数 (BIS)的变化。　结果　 组血压维持术前值的85 %左右 ,SEF 15 .1± 3.7,BIS 6 7.7± 5 .0是较为适宜的麻醉深度。 组循环变化明显 ,特别在切皮 ,进胸探查后需用升压药 ,此时 SEF 12 .3± 3.0 ,BIS 5 5 .0± 6 .2 ,显示麻醉偏深。　结论　老年人胸腔手术 ,不能以 SEF、BIS做为判断连续硬膜外复合静吸麻醉深度的唯一指标 ,需结合血压和 MAC综合判断。Objective\ Using quantitative electroncephalography(EEG) to assess depth of continual cpidural anesthesia(CEA)/general anesthesia(GA) in thoracic surgical elder patients.\ Methods\ 30 elder thoracotomic patient with CEA/GA were divided into group 1(minimum anesthetic concentration,MAC 0 6) and group 2(MAC 1 0) according to inhalaled concentration of forane.\ The changes of BP,HR,SEF,MF,δR and BIS were monitored at after CEA,intubation,incision,thoracotomy,30 minutes after thoracotomy,60 minutes after thoracotomy and end of operation.\ Results\ That BP reduced to 85%,SEF 15 1±3 7,BIS 67 7±5 0 were considered to be suitable depth of anesthesia in group 1.\ BP sharply reduced,SEF 12 3±3 0,BIS 55 0±6 2 were considered to be over depth of anesthesia in group 2.\ Conclusion\ SEF,BIS are not only signs for estimating the depth of anesthesia with CEA/GA in elder,BP,MAC are also needed.\;
