Maneuver

Interventions/Control_1

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).

Interventions/Control_2

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.
