Background: Our study aimed to compare pectoral nerve (PEC) block with local anesthetic (LA) infiltration for providing analgesia in superficial breast surgeries.
Materials and methods: This prospective comparative randomized study included seventy American Society of Anesthesiologists I and II female patients undergoing excision of fibroadenoma. In Group 1, the LA mixture was infiltrated in the desired planes. In Group 2, PEC I and PEC II blocks were performed under ultrasound guidance. Patients were observed at regular time intervals for pain scores, time to first analgesic request, and the number of patients requiring rescue analgesia with the cumulative analgesic requirement, hemodynamic changes, and any adverse events.
Results: The patients were comparable in demographic profile, duration of anesthesia, and hemodynamic parameters. NRS scores at all times after extubation were significantly lower in Group 2 as compared to Group 1 (P < 0.0001). All patients in Group 1 required additional analgesia, while only two in Group 2 received rescue analgesia (P < 0.0001). The time to first analgesic request was significantly longer in Group 1 as compared to group 2 (9.5 + 0.70 h vs. 1.35 + 0.83 h) (P < 0.0001). The cumulative requirement of tramadol in Group 1 (96.88 ± 16.45 mg) was significantly higher than in Group 2 (6.47 ± 26.38 mg) (P < 0.0001). No adverse event was reported in either group.
Conclusion: PEC block is a useful method for achieving effective and long-lasting analgesia. It is an efficient and safe alternative to LA infiltration in patients undergoing fibroadenoma excision.
