The Use of Pecs Blocks in Combination With Exparel in Breast Reconstruction Surgery

Breast Reconstruction (mammaplasty) surgery with implant-based tissue expander

Pectoral nerve (Pecs) blocks I and II function by blocking the pectoral, intercostal, intercostobrachial nerves, and/or long thoracic nerve. These are used primarily for breast surgeries and are gaining momentum as simple administers of local analgesics. Pecs blocks utilize ultrasound to guide injection of local analgesic. It is less invasive and more accurate than most current modes of analgesia administration.

Exparel is a sterile, non-pyrogenic white to off-white preservative-free aqueous suspension of multivesicular liposomes (DepoFoam® drug delivery system) containing bupivacaine. Bupivacaine is present at a concentration of 13.3 mg/mL. After injection of Exparel, bupivacaine is released from the multivesicular liposomes over a period of time.

This is an anesthetic delivered during breast reconstruction surgery that will be given to participants in both arms.
