Background: Breast carcinoma is most common malignancy among female patients. Pain is the most common symptom encountered during post operative period after MRM. Peripheral nerve block is the emerging procedure in anaesthesiology and modified pectoral nerve block 2 and erector spinae plane blocks are given for post operative pain relief in patients undergoing MRM without any side effects.

Aim and Objectives: To compare the effect of modified pectoral nerve block 2 and erector spinae plane block in patients undergoing MRM for post operative pain relief.

Methodology: It is a prospective randomized comparative study conducted in 64 patients undergoing MRM in tirunelveli medical college and hospital. Age group includes 18-65 years of female sex who have given informed written consent. Preanaesthetic evaluation done, checked for iv acess, all monitors connected, hemodynamics before the procedure were noted. Group 1 received modified pectoral nerve block 2 with 0.2% ropivacaine 25ml and group 2 received erector spinae plane block with 0.2% ropivacaine 20ml. pain score after the procedure noted by using VAS score[0-10].

Results: PEC 2 Group recorded a better VAS Recovery score than the ESP Group (mean: 2.5 versus 3.65). Opioid requirment is lower in PEC 2 Group compared to ESP group.

Conclusion: Ultrasound guided regional anaesthesia is playing a major role in terms of providing the patients better post operative care. Modified pectoral nerve block 2 is safe and effective procedure during breast cancer surgeries especially modified radical mastectomy. It shows lower intraop and postoperative opioid consumption than erector spinae plane block.
