76 patients scheduled for elective cesarean delivery under spinal anesthesia to receive the quadratus lumborum block or the transversus abdominis plane block for postoperative pain relief.
Results:
Patients in the quadratus lumborum block group used significantly less morphine than the transversus abdominis plane block group at 12, 24, and 48 hours after caesarean delivery. This group also had significantly fewer morphine demands than the control group at 6, 12, 24, and 48 hours after cesarean delivery.
No significant differences in visual analog scale results were shown between the 2 groups at rest or with movement. Calculated total pain relief at rest and with movement were similar in both groups.
CONCLUSIONS:
The quadratus lumborum block was more effective in reducing morphine consumption and demands than transversus abdominis plane blocks after cesarean section. This effect was observed up to 48 hours postoperatively.
