Primary

MeasureTime frame
correlation between the specific allele of CYP2D6 between responders and non-respondersTimepoint: baseline sample before surgery

Secondary

MeasureTime frame
To compare the total rescue analgesic consumption between the responders and non-responders in 24 hours & The total rescue antiemetic consumption in 24 hours in non-respondersTimepoint: From the blood sample taken at the baseline for gene polymorphism study
