脑电双频指数监测对重症监护病房昏迷患者预后的评估(1)
【摘要】目的 观察脑电双频指数(BIS)监测值与重症监护室(ICU)中昏迷患者预后的相关性,探讨通过BIS值评估ICU昏迷患者的预后的可行性。方法 回顾性将纳入的208例昏迷危重病患者根据所监测的BIS监测值分为四组:Ⅰ组,0~20;Ⅱ组,21~40;Ⅲ组,41~60;Ⅳ组,﹥60。分别用BIS值和神志预后(神志清楚-昏迷、植物状态、脑死亡状态)为目标,比较组间差异,计算各组BIS值与昏迷患者预后的相关性,寻找较准确评估昏迷患者预后的BIS临界值。结果 四组患者的年龄、APACHE Ⅱ评分采用单因素方差分析,差异无统计学意义(P>0.05),对BIS值与昏迷预后状态采用Spearman’s等级相关进行相关分析,结果呈负相关(r=-0.749,P=0.00),根据ROC曲线,当BIS值﹥42.5对神清-昏迷状态预后评估的敏感性及特异性较高。结论 BIS值与ICU昏迷患者的预后之间具有较好的相关性,BIS值可以对ICU昏迷患者的预后进行初步评估。

【Abstract】Objective To investigate the correlation between Bispectral index (BIS) value and the prognosis of patients with coma in ICU. Methods A total of 208 patients with coma in ICU were divided into 4 groups according to the BIS value. In group I, BIS value was 0 to 20; groupⅡ, BIS value 21 to 40; group Ⅲ, BIS value 41 to 60; and group Ⅳ, BIS value greater than 60. Comparison of the difference in BIS value with the differences in prognosis of patients with coma was carried out between four groups, and the prognosis of patients with coma was stratified into consciousness, coma, vegetative state, and brain death. Subsequently, the best cut-off score of BIS value calculated for determining the correlation between BIS and mental state was proposed.Results There are no significant differences in the age and APACHE Ⅱ scores between four groups (P> 0.05). It was inverse correlation between BIS value and mental state (r=-0.749,P=0.00). According to the ROC curve, as BIS value was greater than 42.5, there were higher sensitivity and specificity in Conscious-Coma patients.Conclusions BIS value is correlated with the prognosis of patients with coma in ICU, and BIS value can be a useful marker for estimating the prognosis of comatose patients.

脑电双频指数(bispectral index,BIS)是近年来新提出的一种脑电信号分析方法,目前被认为是最能反映大脑皮质功能状况的指标1。本研究旨观察早期BIS监测与ICU昏迷患者神志恢复的相关性,探讨以BIS评估判断ICU昏迷患者预后的可行性。

1.1 一般资料
病例选自2009年3月至2012年3月天津市第一中心医院ICU收治的患者,经家属知情同意后,纳入208例昏迷危重病患者,主要原发病包括脑血管病、颅脑创伤、心肺复苏术后、病毒性脑炎,排除镇静状态、肝性脑病、肺性脑病、中毒患者(见表1)。患者中男性124例,女性84例。对ICU患者行APACHEⅡ评分、昏迷Glascow评分、脑电双频指数(BIS)监测,并根据BIS监测值分为4组,分别为0~20组,21~40组,41~60组,>60组,基线人口统计学特点见表2。对患者BIS连续监测14 d,记录前72 h BIS值,随访患者28 d神志转归(预后)。预后分为脑死亡状态、植物状态,其余神志状态归为神志清楚-昏迷。, http://www.100md.com(高红梅 路玲 窦琳 常文秀)
