Selective Activation of NAc D1R-VP/LH Circuits Promotes Reanimation From Sevoflurane Anesthesia in Mice.
Emerging evidence has uncovered a vital role of nucleus accumbens (NAc) neurons that express the dopamine D1 receptor (D1R) and its upstream neural circuit in general anesthesia (GA) regulation. However, the underlying downstream neural basis of the modulation of GA emergence by NAc D1R neurons remains unknown. In the present study, we explored the downstream neural mechanism of NAc D1R neurons in the modulation of emergence from sevoflurane GA. ⋯ Both NAc D1R -VP and NAc D1R -LH circuits are sufficient to promote reanimation from sevoflurane GA by simultaneously inducing cortical and behavioral emergence.

ReviewA Narrative Review Illustrating the Clinical Utility of Electroencephalogram-Guided Anesthesia Care in Children.
The major therapeutic end points of general anesthesia include hypnosis, amnesia, and immobility. There is a complex relationship between general anesthesia, responsiveness, hemodynamic stability, and reaction to noxious stimuli. This complexity is compounded in pediatric anesthesia, where clinicians manage children from a wide range of ages, developmental stages, and body sizes, with their concomitant differences in physiology and pharmacology. ⋯ This review discusses anesthetic management principles in a variety of clinical scenarios, including infants, children with altered conscious levels, children with atypical neurodevelopment, children with hemodynamic instability, children undergoing total intravenous anesthesia, and those undergoing cardiopulmonary bypass. Each scenario is accompanied by practical illustrations of how the EEG can be visualized to help titrate anesthetic dosage to avoid undersedation or oversedation when patients experience hypotension or other physiological challenges, when surgical stimulation increases, and when a child's anesthetic requirements are otherwise less predictable. Overall, this review illustrates how well-established clinical management principles in children can be significantly complemented by the addition of EEG monitoring, thus enabling personalized anesthesia care to enhance patient safety and experience.

Randomized Controlled Trial Observational StudyComparison of effects of volatile and intravenous anesthetics on pupillary function during general anesthesia in children: A prospective observational study.
The light reflex, which reflects central nervous system dysfunction, can also be affected by anesthetic agents. ⋯ The Neurological Pupil index value in pediatric patients under general anesthesia is affected by the anesthetic agent used; this factor requires consideration in evaluations of the Neurological Pupil index during general anesthesia.
