This study aims to determine the efficacy of a quadratus lumborum (QL) block in decreasing
postoperative pain in patients undergoing myomectomy for uterine fibroids. A QL block is a
temporary anesthetic injection in the quadratus lumborum muscle, a muscle in the lower back,
that has been previously shown to significantly reduce postoperative pain levels in patients
undergoing abdominal and pelvic surgery. Because of its demonstrated effects, the QL block is
becoming a standard of anesthesia and surgical care. Since participants will be undergoing a
myomectomy procedure, the investigators believe that participants may qualify to participate
in this study. The investigators will be comparing patients who receive the QL block (in
addition to standard anesthesia and postoperative pain care) with patients who do not receive
the QL block (in addition to standard care). The participants will be randomly assigned to
one of the two groups and may or may not actually receive the block.
