Outcomes

Primary Outcomes

Postoperative delirium during the 3 adys-follow-up after anesthetic resuscitation

Postoperative delirium was tested with 3D-Confusion Assessment Method or Confusion Assessment Method-intensive care unit (0-4, higher scores means worse). The patient is determined to be postoperative delirium (ie, Confusion Assessment Method positive) if he/she fall ill quickly with confusion disorder, and with mental disorder or consciousness disorder.

Time frame: From ending of the surgery to 3 days after anesthetic resuscitation

Secondary Outcomes

Postoperative delirium in the postanesthesia care unit

Postoperative delirium was tested with Confusion Assessment Method-intensive care unit. Postoperative delirium was tested with Confusion Assessment Method-intensive care unit (0-4, higher scores means worse outcome). The patient is determined to be postoperative delirium (ie, Confusion Assessment Method positive) if he/she fall ill quickly with confusion disorder, and with mental disorder or consciousness disorder.

Time frame: From ending of the surgery to the time when discharge from postanesthesia care unit, an average of 30 minutes.

Postoperative delirium on the first day after operation

Postoperative delirium was tested with 3D-Confusion Assessment Method (0-4, higher scores means worse outcome). The patient is determined to be postoperative delirium (ie, Confusion Assessment Method positive) if he/she fall ill quickly with confusion disorder, and with mental disorder or consciousness disorder.

Time frame: 9：00-10：00 and 15：00-16：00 on The first day after operation
