Abstract

Background: Postoperative acute and chronic pain following breast surgery is a common complication that needs resolving to allow for improved patient outcomes. Previously, thoracic epidurals and paravertebral blocks have been the accepted standard administered intraoperatively. However, more recently the introduction of the pectoral nerve block (PECS and PECS-2 blocks) has appeared promising to control the pain more effectively, but further robust analysis is required to prove its efficacy. The authors aim to study the efficacy of a new block, S-PECS, that combines a serratus anterior and a PECS-2 block. Methods: In this study, the authors performed a single-center, randomized, controlled, double-blind group trial in 30 female patients undergoing breast augmentation surgery with silicone breast implants and the S-PECS block. Divided into two groups of 15, the PECS group received local anesthetics and the no-PECS control group received a saline injection. All participants were followed up at recovery and at 4, 6, and 12 hours postoperatively. Results: The authors’ results showed that the pain score in the PECS group was significantly less than in the no-PECS group across all time points: recovery, and at 4, 6, and 12 hours. Furthermore, the patients who received the S-PEC block were 74% less likely to request pain medications compared with the no-PECS group (P < 0.05). Conclusion: Overall, the modified S-PECS block is an effective, efficient, and safe method of controlling pain in patients undergoing breast augmentation surgery, with additional applications yet to be explored.
