Abstract
Objective. 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 [D(a - jv)O 2] at T1, T2, and T3, cerebral oxygen uptake (CEO2) levels, and postawakening agitation scores were lower than those of the control group during the same period (P < 0.05).
Highlights
Craniocerebral injury in surgery is more traumatic and patients suffer from nervousness and fear, which require appropriate anaesthetic hypnosis to reduce the occurrence of stress reactions and improve surgical safety
Dexmedetomidine is highly selective for α2 receptors, with an affinity more than 1,600 times that of α1 receptors, inhibits norepinephrine release [2], reduces postsynaptic membrane excitability, has a low preoperative aerodynamic impact, has no respiratory depressant effect, effectively inhibits sympathetic excitation, lowers catechol levels, and reduces the stress response
Dexmedetomidine is a new highly selective α2-adrenergic agonist that can reduce the stress response during surgery and maintain aerodynamic stability [6]. is study will look at the effect of dexmedetomidine in controlled hypotension during craniocerebral injury and its effect on patients’ postoperative cognitive function
