BRILMA Block in Breast-Conserving Surgery

Breast-conserving surgery has become a standard surgical approach in the management of early-stage breast malignancies. Despite being less invasive than other oncologic procedures, postoperative pain remains a significant concern. In postoperative pain management, the addition of regional analgesia techniques to multimodal approaches aims to reduce opioid consumption. First described in 2013, the Serratus-Intercostal Interfascial Plane block targets the branches of the intercostal nerves at the level of the mid-axillary line, specifically around the fourth rib-an anatomical region referred to by the acronym BRILMA. This regional anesthesia technique has demonstrated efficacy in managing postoperative pain, particularly after breast surgery. In the study, investigators planned to evaluate the postoperative analgesic efficacy of ultrasound-guided BRILMA block via 24-hour morphine consumption in patients undergoing breast conserving surgery.
