- Background: Pain control following breast surgery is of utmost importance in order to reduce the chance of chronic pain development, and facilitate early rehabilitation. The erector spinae plane block (ESPB) is a recently developed regional anaesthesia procedure successfully used for different types of surgical procedures including thoracic and abdominal surgeries. Methods: A double-blind, randomized, controlled trial was conducted on 90 patients who were scheduled for modified radical mastectomy (MRM). Patients were randomly categorized into groups I (women who underwent ESPB), II (women who underwent paravertebral block (PVB), and III (women who underwent general anaesthesia). Results: The ESPB (4.9 +/- 1.2 mg) and PVB (5.8 +/- 1.3 mg) groups had significantly lower total morphine consumption than the control group had (16.4 +/- 3.1 mg; p < 0.001). Notably, patients in the ESPB group had insignificantly lower morphine consumption than those in the PVB group had (p= 0.076). Moreover, patients in the ESPB and PVB groups had a significantly longer time to first required anaesthesia than those in the control group (7.9 +/- 1.2 versus 7.5 +/- 0.9 versus 2 +/- 1.2 h, respectively; p<0.001).The postoperative visual analog scale scores were lower in the ESPB and PVB groups than in the control group on the first 24 h after the procedure (p< 0.001). Conclusion: ESPB and PVB provide effective postoperative analgesia for women undergoing MRM. The ESPB appears to be as effective as the PVB.
