[摘要] 目的 通过临床分析手术期间全身麻醉下脑电双频指数(Bls)和麻醉深度指数(CSI)的变化来调整麻醉药用量,评价BIS、CSI在监测麻醉深度方面的实用性。方法 随机选择2013年5月—2014年11月该院收治的拟在丙泊酚与瑞芬太尼麻醉下施实气管内插管的全麻患者160例,按照瑞芬太尼靶浓度随机均分为4组:R1组(0.9%氯化钠)、R2、R3、R4组分别为2.0 μg/(kg·min)、3.0 μg/(kg·min)、4.0 μg/(kg·min)瑞芬太尼。结果随着4组患者OAA/S评分的降低,BIS、CSI也逐渐降低(P<0.05);同时OAA/S评分下,R2~R4组的BIS、CSI高于R1组(P<0.05)。Speaman等级相关分析结果表明:BIS或CSI与OAA/S评分有相关性,但各组间相关系数比较差异无统计学意义。R1~R4组患者在睫毛反射消失及强直刺激反应消失时的CSI、BIS均高于R1组。结论 CSI与BIS相似,能较好地反映全麻手术患者镇静深度的变化;两者的变化均受到血浆镇痛药物浓度改变的影响,与OAA/S评分相关性一致。

[Abstract] Objective through clinical observation during surgery under general anesthesia electrical dual-frequency (Bls) and the anesthesia depth index (CSI) changes to adjust drug dosage, evaluation the BIS, the practicability of CSI in monitoring the depth of anesthesia. Methods Random selection in propofol anesthesia with fentanyl ShiShi endotracheal intubation of 160 cases of patients with general anesthesia, according to the red target concentration of fentanyl randomly were divided into four groups: R1 group (0.9% sodium chloride), R2:, R3 and R4 group were 2.0, 3.0, 4.0 mu g/(kg·min) fentanyl. The results of With the loss of the OAA/S score four groups of patients, the BIS, CSI also gradually reduced(P < 0.05); OAA/S score at the same time, the BIS, CSI is higher than the R1, R2 and R4 group group(P < 0.05). Speaman rank correlation analysis results show that the BIS or CSI has correlation with OAA/S score, but there was no statistically significant difference in the correlation coefficients between each group. R1 and R4 patients disappeared in eyelash reflex and tetanic stimulation reaction disappears CSI, BIS were higher than in R1 group. Conclusion CSI is similar to the BIS, can well reflect the general anesthesia surgery patients sedation depth change; Change of both types of influenced by analgesic drug plasma concentration changes, consistent with OAA/S score correlations.

全身麻醉手术中,患者若术中知晓往往会引发心理反感、恐惧等不良情绪,进而对手术产生恐惧,且对手术医生表现出程度各异的不信任感等诸如此类逆反心理。对于全麻患者来说,其在手术前通常应用肌松药辅助麻醉,因此单纯通过体动以及呼吸这两项指标来评估麻醉深度已经失去其原有意义,此种情况下判断全麻患者麻醉深度也显得越来越困难。因全身麻醉药物导致的意识改变与大脑电活动变化密切相关,故被广泛用于监测麻醉深度和预测意识变化。近年来随着临床监测技术与手段的快速发展,麻醉深度监测工作有了进一步改善,其中脑电双频指数(Bispectral Index,BIS)以及麻醉深度指数(cerebral state index,CSI)成为临床监测全麻患者常用的两项指标。其中麻醉深度指数(cerebral state index,CSI)作为一种近几年出现的临床麻醉深度监测指标,其临床意义已得到诸多研究证实,而最新研究表明,单纯输注丙泊酚时通过CSI指标可患者镇静深度予以准确监测[1-3]。……
