Head trauma is one of the most important emergency health problems both in the world and in our country. The objective in our study is to (i) state the correlation between the findings of bispectral index score (BIS) and computed tomography (CT), which are used to evaluate the level of consciousness of patients with isolated head trauma, and (ii) investigate objective results about the patient's level of consiousness/alertness according to the CT modality, which is used frequently.
This prospective study was carried out between 03.01.2014 and 09.01.2014 in the emergency department of Fatih Sultan Mehmet Education and Research Hospital. The average BIS scores were correlated with the Glasgow Coma Scale (GCS) point, the Canadian CT Head Rule major and minor criteria, and the pathologic findings in CT imaging. The patients' demographic features, vital signs at admission, and arrival times at the hospital were investigated.
In our study, 64 (31.7%) patients were female, and 138 (68.3%) patients were male. The mean BIS scores were 84.99±11.20 (86.05) and 93.78±3.80 (95.05) in patients with and without CT pathologies, respectively. The correlation between CT pathology and BIS scores was statistically significant: BIS scores were lower in patients with CT pathologies (p=0.001; p<0.01). There was a statistically significant positive correlation between the BIS and GCS scores (45.6%) (p<0.05).
We showed that most head traumas occur after dangerous accidents, and according to the results, we can predict that males are more frequently affected than females. There was a statistically significant positive correlation between BIS scores and GCS points. In our study, the BIS scores were statistically significantly lower in patients with CT pathology than in patients without. We can predict that if the BIS score of the patient is low, then there will be the presence of pathology on CT imaging.
颅脑外伤是全球及我国最重要的紧急健康问题之一。本研究的目的是：（i）阐述用于评估单纯性颅脑外伤患者意识水平的脑电双频指数（BIS）评分结果与计算机断层扫描（CT）结果之间的相关性；（ii）根据常用的CT检查方式，研究关于患者意识/警觉水平的客观结果。
本前瞻性研究于2014年1月3日至2014年1月9日在法提赫·苏丹·穆罕默德教育与研究医院急诊科开展。将平均BIS评分与格拉斯哥昏迷量表（GCS）评分、加拿大CT头颅扫描规则的主要和次要标准以及CT影像中的病理结果进行相关性分析。调查了患者的人口统计学特征、入院时的生命体征以及到达医院的时间。
在我们的研究中，女性患者64例（31.7%），男性患者138例（68.3%）。有CT病理改变的患者平均BIS评分为84.99±11.20（86.05），无CT病理改变的患者平均BIS评分为93.78±3.80（95.05）。CT病理改变与BIS评分之间的相关性具有统计学意义：有CT病理改变的患者BIS评分较低（p = 0.001；p < 0.01）。BIS评分与GCS评分之间存在统计学意义的正相关（45.6%）（p < 0.05）。
我们发现大多数颅脑外伤发生在危险事故之后，根据结果可以预测男性比女性更容易受到影响。BIS评分与GCS评分之间存在统计学意义的正相关。在我们的研究中，有CT病理改变的患者BIS评分在统计学上显著低于无CT病理改变的患者。我们可以预测，如果患者的BIS评分较低，那么CT影像上将会存在病理改变。
