Why the study?
Failure to provide effective pain control after breast surgery impairs recovery, prompting comparison of modified pectoral nerve block versus erector spinae plane block for post-operative pain relief.
Does modified pectoral nerve block improve postoperative pain control compared to erector spinae block in female patients undergoing modified radical mastectomy?
Population
80 female patients aged 25-65 years undergoing modified radical mastectomy
Comparison
Modified pectoral nerve block vs erector spinae block
Design
Prospective randomized comparative study
Key result
Modified pectoral nerve block significantly reduced 24-hour postoperative morphine consumption (4.6 mg vs 7.5 mg) and prolonged the duration of analgesia compared to erector spinae block in patients undergoing modified radical mastectomy.

Absolute Event Rate: 4.6% vs 7.5%
p-value: p=0.0007
Modified pectoral nerve block provides superior postoperative analgesia and reduces opioid consumption compared to erector spinae block in patients undergoing modified radical mastectomy.
Shanmugam et al. (2023) conducted an RCT in Breast cancer undergoing modified radical mastectomy (n=80). Modified pectoral nerve block vs. Erector spinae block was evaluated on Total morphine consumed in 24 hours (mg) (p=0.0007). Modified pectoral nerve block significantly reduced 24-hour postoperative morphine consumption (4.6 mg vs 7.5 mg) and prolonged the duration of analgesia compared to erector spinae block in patients undergoing modified radical mastectomy.
