BackgroundAbdominal hysterectomy is associated with sever postoperative pain. Quadratus lumborum (QL) block is a regional analgesic technique which has an evolving role in postoperative analgesia.Aimswe aimed to compare ultrasound guided bilateral transverse abdominis plane (TAP) block versus bilateral QL block in patients undergoing total abdominal hysterectomy.Settings And DesignThis is a prospective randomized controlled double blinded study.Patients And MethodsSixty adult female patients (ASA I-II), scheduled for total abdominal hysterectomy were randomized into two equal groups (TAP group and QL group). Each patient received general anesthesia plus bilateral TAP block or bilateral QL block. We recorded postoperative total dose of morphine used / 24 hours, Visual Analuge Scales (VAS) for pain (at 30 min, 2, 4, 6, 12, and 24 hours postoperative), duration of postoperative analgesia, total dose of fentanyl use intraoperative, number of patients needed rescue analgesia and any side effects.Statistical AnalysisIndependent sample T test and Chi-Square (X2) test were used as appropriate.ResultsPatients in QL group consumed significantly less fentanyl and morphine than patients in TAP group, VAS for pain was significant higher in TAP group than in QL group at all times, the duration of postoperative analgesia was shorter in TAP group than in QL group, the number of patients requested analgesia was significantly higher in TAP group than in QL group.ConclusionsBilateral QL block provided better intraoperative and postoperative analgesia with less opioids consumption compared with bilateral TAP block, in patients undergoing total abdominal hysterectomy.
