Previous studies have shown that paravertebral block (PVB) has the potential to reduce pain and side effects after breast surgery when used in addition to general anesthesia or sedation.The investigators would like to further discern the impact of GA or PVB on the postoperative QoR, pain and satisfaction.

Arms Assigned Interventions
Experimental: general anesthesia and PVB
general anesthetics consisting of propofol, cisatracurium and fentanyl for endotracheal intubation and deaflurane for maintenance will be given. After intubation, paravertebral injections will be performed under ultrasound guidance.
Other: PVB
paravertebral block
Experimental: sedation and PVB
After sedation with midazolam and fentanyl, the patients in sedation and PVB group will receive PVB. paravertebral injections will be performed under ultrasound guidance.Intraoperative sedation will be provided with propofol titrated to moderate sedation.
Other: PVB
paravertebral block
Active Comparator: general anesthesia
general anesthetics consisting of propofol, cisatracurium and fentanyl for endotracheal intubation and deaflurane for maintenance will be given.
Other: PVB
paravertebral block
