Background: laparoscopic hysterectomy is associated with sever postoperative pain. Quadratus lumborum (QL) block is a regional analgesic technique which has an evolving role in postoperative analgesia.
Aims: we aimed to compare ultrasound guided bilateral transversus abdominis plane (TAP) block versus bilateral Quadratus lumborum block in patients undergoing total laparoscopic hysterectomy.
Settings and Design: This is a prospective randomized controlled double blinded study. Patients and Methods: Sixty adult female patients (ASA I-II), scheduled for total laparoscopic hysterectomy were randomized into two equal groups (TAP group and QL group). Each patient received general anesthesia and after completion of surgery and before extubation bilateral TAP block or bilateral QL block. We recorded Visual Analogue Scales (VAS) for pain (at 30 min, 2, 4, 6, 12, and 24 hours postoperative), duration of postoperative analgesia, number of patients needed rescue analgesia and any side effects.
Statistical Analysis: student unpaired T test and Chi-Square (X2) test were used as appropriate.
Results: 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.
Conclusions: Bilateral QL block provided better postoperative analgesia in patients undergoing total laparoscopic hysterectomy.
Key words: Quadratus lumborum block,Trans versus Abdominis plane block, laparoscopic total hysterectomy,Randomized trail.
