The aim of this study is to examine the effectiveness of intramuscular quadratus lumborum block for postoperative analgesia after cesarean section.
Efficacy
Time to first analgesic use after cesarean section
number of analgesic use within 24 hours after surgery, postoperative numerical rating scale (NRS) (0, 2, 4, 6, 8, 10, 12, 24, 48 hours after surgery), presence of adverse events

Treatment
Maneuver |
1) Before surgery, spinal anesthesia is performed from the L3/4 (or L2/3) with 2.0-2.2 mL of 0.5% hyperbaric bupivacaine and 15 mcg (0.3 mL) of fentanyl
2) Depending on cases, droperidol about 1 mg administered soon after delivery
3) Acetaminophen 1000 mg is administrationed in 15 min at the end of surgery in all cases
After the surgery, in the control group, 0.4 ml/kg of normal saline is injected into bilateral quadratus lumborum muscle under ultrasound-guided (total volume is 0.8 ml/kg).
In the intramuscular QLB group, spinal anesthesia and intraoperative management as same as control group are performed. However, after surgery, 0.25% ropivacaine 0.4 mL/kg is administered bilaterally as intramuscular QLB (total volume is 0.8 mL/kg). The total amount of ropivacaine used is 2 mg/kg.
Because this study is a double-blind study, patient, anesthesiologist performed block techniques and ward staff are not imformed which drug (normal saline/ropivacaine) is used. All cases are managed as administered ropivacaine. Patients can use some analgesics whenever they need after surgery.
