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....
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...
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...
