Effect of intraoperative esketamine on moderate-to-severe depressive symptoms in major surgery patients: A randomized clinical trial.

Pharmacological Research July 1, 2026 Yang Zhou, Wanchen Sun, Yuxuan Fu et al.

Perioperative depressive symptoms (PDSs) are common among patients who undergo major surgery and can lead to worse clinical outcomes. Esketamine has been reported to alleviate PDSs in patients undergoing certain types of surgery. However, there is a lack of evidence from large-scale, multisurgery studies to support its therapeutic effects in individuals with preexisting moderate-to-severe PDSs....

Acute Effects of Esketamine on the EEG Power Spectrum and Signal Complexity in Prolonged Disorders of Consciousness: A Prospective Exploratory Cohort Study.

Journal of neurosurgical anesthesiology June 15, 2026 Yi Liang, Wanning Yang, Xinxin Wang et al.

Effective treatments for prolonged disorders of consciousness (pDoC) remain limited. Grounded in the entropic brain hypothesis-that psychedelic agents facilitate consciousness recovery by increasing brain complexity-this study investigated esketamine, a nonclassical psychedelic drug, and its effects on electroencephalographic (EEG) neurophysiological metrics in pDoC patients. In this...

Effect of esketamine combined with pregabalin on acute postsurgical pain in patients who underwent resection of spinal neoplasms: a randomized controlled trial.

Pain September 1, 2024 Yang Zhou, Wanchen Sun, Yuxuan Fu et al. 9 citations

Moderate-to-severe acute postsurgical pain (APSP) can prolong the recovery and worsen the prognosis of patients who undergo spinal surgery. Esketamine and pregabalin may resolve APSP without causing hyperpathia or respiratory depression after surgery. However, there are other risks, such as dissociative symptoms. We designed a randomized controlled trial to investigate the effect of the...

Hierarchical fluctuation shapes a dynamic flow linked to states of consciousness.

Nature Communications June 5, 2023 Ang Li, Haiyang Liu, Xu Lei et al.

Consciousness arises from the spatiotemporal neural dynamics, however, its relationship with neural flexibility and regional specialization remains elusive. We identified a consciousness-related signature marked by shifting spontaneous fluctuations along a unimodal-transmodal cortical axis. This simple signature is sensitive to altered states of consciousness in single individuals, exhibiting...

Dynamic Reconfiguration of Human Brain Networks Across Altered States of Consciousness.

Behavioural Brain Research November 1, 2021 Haiyang Liu, Ke-Hui Hu, Yingjie Peng et al.

Consciousness is supported by rich neuronal dynamics to orchestrate behaviors and conscious processing can be disrupted by general anesthetics. Previous studies suggested that dynamic reconfiguration of large-scale functional network is critical for learning and higher-order cognitive function. During altered states of consciousness, how brain functional networks are dynamically changed and...
