Ultrasound-guided Bi-level Erector Spinae Plane Block and Pre-emptive Single-dose Oral Tizanidine for Postoperative Analgesia After Mastectomy Surgery: a Prospective, Randomized, Controlled Trial
Effective management of postoperative pain in breast cancer surgery is essential to minimize the risk of developing postmastectomy pain syndrome.The aim of this study is to evaluate the effectiveness of combining bilevel erector spinae plane (ESP) block with a single preoperative oral dose of tizanidine in improving postoperative analgesia in patients undergoing mastectomy surgery. It is hypothesized that the combination of bilevel ESP block and single-dose oral tizanidine will provide superior postoperative analgesia compared to bilevel ESP block alone in patients undergoing mastectomy.
