Patients scheduled for mastecotmy will be randomized to receive either an ultrasound-guided double space paravertebral block or a PECSII + parasternal block. In both groups, blocks will be performed with 20 ml of ropivacaine 0.75%, plus ropivacaine 0.375% 10 ml for parasternal block only. Postoperative, all patients will receive a morphine PCA. They will follow at 6, 12, 24 months for persistent postoperative surgical pain (PPSP) and cancer recurrence.
