. To observe the controlled effect of dexmedetomidine for neurosurgery and the effect on postoperative cognitive function. The main task of this paper is to use data from a small sample. The proposed feature extraction algorithm based on the bilinear convolutional neurological network (BCNN) is based on a small sample of data. BCNN involves the simultaneous extraction of highly discriminative cross-sectional features from the input image using two parallel subnetworks. By optimizing the algorithm to minimize losses, the two subnetworks can be supervised by each other, improving the performance of the network and obtaining accurate recognition results without spending a lot of time adjusting parameters. The mean arterial pressure (MAP) and heart rate (HR) levels of cerebral oxygen metabolism were compared between the two groups before (T0), after (T1), immediately after (T2), and after intubation (T3). In the observation group, MAP and HR values at T3, arterial-internal jugular vein bulb oxygen difference [( - ) ] at T1, T2, and T3, cerebral oxygen uptake (CEO) levels, and postawakening agitation scores were lower than those of the control group during the same period ( < 0.05).
观察右美托咪定在神经外科中的控制效果及对术后认知功能的影响。本文的主要任务是使用小样本数据。基于双线性卷积神经网络（BCNN）的提出的特征提取算法基于小样本数据。BCNN 涉及使用两个并行子网同时从输入图像中提取高度有区别的横向特征。通过优化算法使损失最小化，两个子网可以相互监督，从而提高网络的性能，并获得准确的识别结果，而无需花费大量时间调整参数。比较两组患者在（T0）前、（T1）后、（T2）即刻和（T3）插管后的平均动脉压（MAP）和脑氧代谢心率（HR）水平。观察组 T3 时的 MAP 和 HR 值、T1、T2 和 T3 时的动脉-颈内静脉球血氧差[（-）]、脑氧摄取（CEO）水平和苏醒后躁动评分均低于同期对照组（<0.05）。
