Name
Effects of esketamine on EEG
Description
The propofol-refentanil program-controlled closed-loop target-controlled infusion system based on NI guidance has been clinically verified. In the case of clinical use of esketamine, the separation anesthesia properties do not affect the accuracy and safety of closed-loop system guidance. However, whether the specific degree of impact can be quantified, and based on quantitative indicators, this model can be better applied to a wider range of clinical actual conditions and different drug administration backgrounds.

Treatment
Subanesthetic dose of esketamine
Both groups were given NI-guided propofol-refentanil dual-channel closed-loop target-controlled infusion under general anesthesia with a laryngeal mask/endotracheal intubation. The experimental group (EEG feedback index 36+N) and the control group (EEG feedback index 36) were intravenously injected esketamine 0.2mg∙kg-1 before anesthesia induction, followed by continuous 5μg∙kg-1∙min-1 infusion to maintain anesthesia for 30 minutes, and the maximum cumulative dose allowed was 100mg. In both groups, the infusion was stopped 30 minutes before the end of surgery.
