Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The following items are investigated before surgery; Age, sex, level of education, type of surgery, past surgical history, presence of chronic pain, the expected maximal pain score (VAS) after surgery, Pain catastrophizing scale, anxiety scale (HADS-A), Pain sensitivity questionnaire, and pain threshold measured by electronic algometer.
The total opioid consumption is investigated for 24 and 48 hours after surgery. In addition, the severity of postoperative pain is measured by the 11-point VAS at 24 and 48 hours after surgery. Patient satisfaction with postoperative pain control is also investigated at 48 hours after surgery using the 7-point patient's satisfaction scale.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
study group
The following tests will be performed on the study subjects.
1. Pain catastrophizing scale
2. Hospital Anxiety and Depression scale-Anxiety Subscale (HADS-A)
3. Pain sensitivity questionnaire
4. Pain pressure threshold using electronic digital pressure algometer
Electronic digital pressure algometer
Evaluation of pain threshold using an algometer is conducted one day before surgery.
The pressure of the plunger of algometer is applied vertically to the patient's right thenar muscle belly at a speed of 10 N/sec by the tester. Then the tester removes the algometer when the patients start to feel pain and record the pressure recorded on the algometer.
Pain sensitivity questionnaire
Evaluation of pain threshold using the Korean-version pain sensitivity questionnaire is conducted one day before surgery.
