Pectoral nerve (PecS II) block is the latest modality for providing postoperative analgesia after breast surgery. The present study was planned to compare the analgesic efficacy of thoracic paravertebral block (TPVB) and PecS II for postoperative analgesia after modified radical mastectomy (MRM). ⋯ The 0.25% levobupivacaine with dexamethasone 4 mg in PecS II block provided longer duration of analgesia than the TPVB in patients undergoing MRM without any adverse effects.
