Esketamine at a Clinical Dose Attenuates Cerebral Ischemia/Reperfusion Injury by Inhibiting AKT Signaling Pathway to Facilitate Microglia M2 Polarization and Autophagy.
Drug Des Devel Ther
January 2025
Department of Anesthesiology, Beijing Friendship Hospital, Capital Medical University, Beijing, People's Republic of China.
Purpose: This study aimed to assess the protective effect of a clinical dose esketamine on cerebral ischemia/reperfusion (I/R) injury and to reveal the potential mechanisms associated with microglial polarization and autophagy.
Methods: Experimental cerebral ischemia was induced by middle cerebral artery occlusion (MCAO) in adult rats and simulated by oxygen-glucose deprivation (OGD) in BV-2 microglial cells. Neurological and sensorimotor function, cerebral infarct volume, histopathological changes, mitochondrial morphological changes, and apoptosis of ischemic brain tissues were assessed in the presence or absence of esketamine and the autophagy inducer rapamycin.
Effect of Esketamine on Cognitive Recovery After Propofol Sedation for Outpatient Colonoscopy: A Randomized Clinical Trial.
Drug Des Devel Ther
January 2025
Department of Anesthesiology, Shengli Clinical Medical College of Fujian Medical University, Fujian Provincial Hospital, Fuzhou, Fujian, People's Republic of China.
Purpose: While esketamine shows promise as an adjunct in procedural sedation, its impact on postoperative cognitive recovery remains incompletely characterized. This study investigated the effects of esketamine on multiple dimensions of recovery, particularly cognition, in patients undergoing colonoscopy with propofol-based sedation.
Patients And Methods: We conducted this randomized, double-blinded, placebo-controlled trial from January 6, 2023, to May 20, 2024, at two hospitals in China.
Anesthesia depth monitoring during opioid free anesthesia - a prospective observational study.
BMC Anesthesiol
January 2025
Department of Anesthesiology and Intensive Care Medicine, Halland Hospital Halmstad, Lasarettsvägen, Halmstad, SE-30581, Sweden.
Background: Patients undergoing general anesthesia are more frequently monitored for depth of anesthesia using processed electroencephalography. Opioid-free anesthesia is nowadays an accepted modality for general anesthesia, however it is unclear how to interpret data from processed electroencephalography when using a mixture of non-opioid anesthetic drugs. Our objective was to describe density spectral array patterns and compare processed encephalographic data indices between opioid-free and routine opioid based anesthesia.

Oral Esketamine as Alternative for Maintenance Electroconvulsive Therapy in Patients With Treatment-Resistant Depression: A Case Series.
J ECT
January 2025
From the Department of Psychiatry, University Medical Centre Groningen, University of Groningen, Groningen, the Netherlands.
Objectives: This study investigates repeated oral esketamine as a substitution strategy for maintenance electroconvulsive therapy (M-ECT) in eight patients with treatment-resistant depression (TRD).
Methods: In a 6-week dosing phase, esketamine was titrated from 0.5 or 1.
