What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Degree of pain by visual Analog Scale (VAS) score at rest | Pain scores will be observed and recorded using the Visual Analog Scale (VAS) both at rest and during movement. The scores will be recorded in the ward at 2, 4, 8, 12, and 24 h. VAS score from 0 to 10 (0: No pain, 10: The worst pain) | First 24 hours postoperative | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Degree of pain by visual Analog Scale (VAS) score at movement | Pain scores will be observed and recorded using the Visual Analog Scale (VAS) both at rest and during movement. The scores will be recorded in the ward at 2, 4, 8, 12, and 24 h VAS score from 0 to 10 (0: No pain, 10: The worst pain) | First 24 hours postoperative | 
| Total rescue analgesics consumption |  | First 24 hours postoperative | 
| The time to first analgesic |  | First 24 hours postoperative | 
| 24-h morphine consumption |  | First 24 hours postoperative | 
| Side effects associated with morphine |  | First 24 hours postoperative |
