Background and objective: Pectoral nNerve (PECS) block type-1 is an Ultrasound (US)-guided interfacial block that can be performed for postoperative analgesia management after breast surgery. In the procedure, a local anesthetic solution is injected into the interfacial area between the Pectoralis Major muscles (PMm) and Pectoralis minor muscles (Pmm). The present study compared PECS block type-1 administered preoperatively or postoperatively for postoperative analgesia after breast augmentation surgery.
