Continuous Pectoral Nerve Block in Breast Cancer Surgery

The Effect of Continuous Pectoral Nerve Block on Postoperative Analgesia Consumption in Breast Cancer Surgery

The purpose of the study is to evaluate the effect of continuous pectoral nerve block on postoperative analgesia consumption in breast cancer surgery.

Pectoral nerve block has been developed as an alternative to thoracic paravertebral and/or thoracic epidural blocks in recent years. It is frequently applied for postoperative analgesia in breast cancer surgery.
