Postoperative Pain
Conditions
Brief summary
This study aims to observe the impact of perioperative body temperature on postoperative pain and pain sensitization for the patients with laparoscopic surgery. Based on this study the investigators aimed to explore the effect of perioperative hypothermia on postoperative pain.
Detailed description
This study aims to included surgery patients to observe the impact of perioperative body temperature on postoperative pain and pain sensitization for the patients with laparoscopic surgery. Body temperature and postoperative pain will be continuously assessed, and then association analysis will be performed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Patients' pain score after surgery | From ending of the surgery to 24 hours after anesthetic resuscitation | The patients' pain score was tested with Numerical analogue scale of pain (0-10, 0 represents pain free, and 10 represents unbearable pain). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patients' pain score during postanesthesia care unit | From ending of the surgery to the time when discharge from postanesthesia care unit with a mean of 30 minutes after surgery | The patients' pain score was tested with Numerical analogue scale of pain (0-10, 0 represents pain free, and 10 represents unbearable pain). |
| Pressure pain threshold | From beginning of the surgery to the time when discharge from postanesthesia care unit with a mean of 30 minutes after surgery | the patients' pain threshold was tested by tenderness meter. |
