Brief summary (from the registry)

The project will apply the methods of clinical observation experiment, (1) to collect the cognitive function data preoperatively and early postoperatively, as well as the pain score data at multiple time points pre- and postoperatively, and to observe the role of the degree of recovery of early postoperative cognitive function on acute pain and chronic pain after surgery. (2) to collect the resting-state electroencephalography (EEG) preoperatively, and to assess the role of EEG index system on the prediction of the degree of recovery of early postoperative cognitive function as well as the acute pain and chronic pain after surgery.
