Primary Outcome Measures

Name	Time	Method
The primary outcome of this study is opioid consumption within the first 36 hours following surgery. This will be measured by the amount of morphine used in the PCA pump after 36h. Therefore, after 36 hours, we will analyze and collect the data of morphine consumption in the PCA pump. [36 hours after the surgery finished]
