COMPARISON OF ULTRASOUND GUIDED MODIFIED PECTORAL NERVE BLOCK WITH LOCAL ANAESTHESTIC INFILTRATION FOR ANALGESIA IN BREAST CANCER SURGERY

Objective: To compare the frequency of pain and mean analgesia requirement after breast surgery under general anaesthesia when comparing pectoral nerve block with local anaesthesia infiltration. Study Design: Comparative prospective study. Place and Duration of Study: Combined Military Hospital, Rawalpindi from Mar 2018 to Sep 2019. Methodology: A total of 60 patients undergoing modified radical mastectomy were included in the study. Group A (n=30) received pectoral nerve blocks while Group B (n=30) received local anaesthetic infiltration. Outcome was assessed at 12 hours after injection of local anaesthetic. Results: Pain in 7 (23.33%) patients in Group A (Pectoral nerve blocks) and in 20 (66.67%) patients in Group B (Local anaesthetic infiltration), p-value of 0.001 which was considered statistically significant. Mean analgesic requirement was found to be 80 ± 33.73 mg in the Group A (pectoral nerve blocks) compared with 141.67 ± 47.50 mg in Group B (Local anaesthesia infiltration) patients with a p-value of <0.001 which was statistically significant. Conclusion: Pectoral nerve block significantly reduces early postoperative pain and analgesia requirement when compared with Local anaesthesia infiltration after breast surgery.
