The clinical impact of pectoral nerve block in an 'enhanced recovery after surgery' program in breast surgery.

Background: Pectoral nerve block (PECS) is increasingly performed in breast surgery. Aim: The study evaluated the clinical impact of these blocks in the postoperative course. Patients & methods: In this case-control study, patients undergoing breast surgery with 'enhanced recovery after surgery' pathways were divided into group 1 (57 patients) in whom PECS was performed before general anesthesia, and group 2 (57 patients) in whom only general anesthesia was effected. Results: Postoperative opioid consumption (p < 0.002), pain at 32 h after surgery (p < 0.005) and the length of stay (p < 0.003) were significantly lower in group 1. Conclusion: Reducing opioid consumption and pain after surgery, PECS could favor a faster recovery with a reduction in length of stay, ensuring a higher turnover of patients undergoing breast surgery.
