The Effects of Erector Spinae Plane Block on Pain Scores in Unilateral Breast Cancer Surgery

The high incidence of breast cancer is increasing the need for oncologic breast surgery. The optimal acute postoperative pain management after breast surgery is not yet clear. The erector spinae plane block (ESPB) is a newer and may be potentially safer alternative other regional analgesia techniques. We will investigate the effectiveness of ESP for managing acute pain after breast cancer surgery. Patients will randomise to receive either ESP block (Group1)or no ESP block (Group II). The primary outcome is postoperative pain scores used Visual Analog Scale (VAS), and the secondary outcomes include intraoperative opioid consumption postoperative total opioid consumption and patient satisfaction.
