Ultrasound continuous erector spinae catheter versus paravertebral catheter for pain management in modified radical mastectomy for cancer patients: A randomized double-blind

Abstract

Background Regional analgesia provides adequate management of pain during mastectomies and early postoperative period. The erector spinae plane block (ESPB) is a promising regional technique. This study compared the efficacy of ESPB versus paravertebral block (PVB) catheters for pain management in modified radical mastectomy (MRM).
