What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: From ending of the surgery to 3 days after anesthetic resuscitation
Secondary outcomes (4)
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.
Measured: 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.
Measured: 9：00-10：00 and 15：00-16：00 on The first day after operation
Postoperative delirium on the second 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.
Measured: 9：00-10：00 and 15：00-16：00 on The second day after operation
Postoperative delirium on the third 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.
Measured: 9：00-10：00 and 15：00-16：00 on The third day after operation
