General anesthesia induces reversible changes in consciousness through cortical activity and connectivity alterations, yet the functional connectome dynamics underlying propofol-induced unconsciousness remains unclear. We analyze high-density 128-channel electroencephalogram (EEG) from 31 surgical patients using source localization to identify neurobiological connectome signatures of propofol...
To determine whether intraoperative low-dose esketamine ameliorates depression in women having breast cancer surgery. A prospective single-center double blind randomized placebo-controlled trial. Perioperative period, operating room, post anesthesia care unit and hospital ward. 108 women 18-65 years old who were scheduled for elective breast cancer surgery. All had preoperative depressive...
To determine whether a single low dose of esketamine administered after childbirth reduces postpartum depression in mothers with prenatal depression. Randomised, double blind, placebo controlled trial with two parallel arms. Five tertiary care hospitals in China, 19 June 2020 to 3 August 2022. 364 mothers aged ≥18 years who had at least mild prenatal depression as indicated by Edinburgh...
BACKGROUND: Remifentanil-induced secondary hyperalgesia has been documented experimentally in both animals and healthy human volunteers, but never clinically. This study tested the hypotheses that increased pain sensitivity assessed by periincisional allodynia and hyperalgesia can occur after relatively large-dose intraoperative remifentanil and that small-dose ketamine prevents this...
