Randomized Controlled Trial
The Efficacy of Ultrasound-guided Type II Pectoral Nerve Blocks in Perioperative Pain Management for Immediate Reconstruction after Modified Radical Mastectomy. A Prospective, Randomized Study.
The pectoral nerves (Pecs) II block is a technique that places local anesthetic between the thoracic muscles to block the axillary and breast regions. This study aimed to compare the quality of perioperative analgesia and side effects of the Pecs II block under general anesthesia versus general anesthesia alone in immediate unilateral breast reconstruction with an implant and latissimus dorsi flap after modified radical mastectomy. ⋯ When patients underwent immediate breast reconstruction with an implant and latissimus dorsi flap, the Pecs II block offers a comprehensive block of associated nerves in the surgical area, and therefore can provide superior analgesia and reduced perioperative opioids use without obvious block-related complications.
