Outcomes
Primary Outcomes
Postoperative delirium during the 3 days-follow-up after anesthetic resuscitation
Time Frame: From ending of the surgery to 3 days after anesthetic resuscitation
Postoperative delirium was tested with 3 minutes-Confusion Assessment Method or 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.
Secondary Outcomes
- Hospital stay(From the ending of the surgery to hospital discharge, with means of about 7 days)
- Postoperative delirium in the postanesthesia care unit(From ending of the surgery to the time when discharge from postanesthesia care unit, an average of 30 minutes)
- Postoperative complication(From the ending of the surgery to hospital discharge, with means of about 7 days)
