Comparing Two Pain Relief Techniques During Modified Radical Mastectomy Costotransverse Foramen Block vs Erector Spinae Plane Block

What this Trial Is About

This trial evaluates two types of nerve blocks, the costotransverse foramen block and the erector spinae plane block, in adult women undergoing modified radical mastectomy, a surgery often followed by significant pain affecting the upper limbs, axillae, and chest area. The study compares how these blocks may help reduce the need for pain medication after surgery. Both nerve blocks aim to provide pain relief by targeting nerves in the thoracic region but differ in technique and anesthetic distribution. Participants will be randomly assigned to receive either an ultrasound-guided costotransverse foramen block or erector spinae plane block on the same side as the surgery. Each block involves injecting 20 ml of 0.25% bupivacaine, a local anesthetic, to manage postoperative pain. These procedures are performed before surgery to help control pain afterward. During the study, researchers will monitor morphine use in the first 24 hours after surgery as the main outcome. They will also assess pain levels for up to 48 hours, track the time until the first request for additional pain relief, and record intraoperative fentanyl use. Heart rate, blood pressure, and any side effects will be observed during and after surgery to evaluate safety and effectiveness. Participants will be followed closely during the immediate postoperative period to gather these data.
