COMBIPECS, the single-injection technique of pectoral nerve blocks 1 and 2: a case series

Ultrasound-guided Pecs block can provide perioperative analgesia for breast surgery. A single-injection technique (COMBIPECS) combines both Pecs 1 and Pecs 2 blocks in a single needle pass. This technique saves time and is equally effective as the modified Pecs block which uses 2 needle passes. We present a case series of 21 patients who received the COMBIPECS block as a part of multimodal analgesia for breast cancer surgery. The block was administered before the surgery after induction of general anesthesia. The patients needed minimal intraoperative analgesics and remained pain free in the postoperative period up to 24 hours after surgery.
