Interventions/Control_1
The computer randomly assign patients to low dose quadratus lumborum block group (Group L, n=20) or moderate dose group (Group M, n=20). Patient is blinded from the administration. In Group L, the ultrasound-guided quadratus lumborum block is performed under general anesthesia. 0.2ml/kg of 0.375% ropivacaine are administered on operation sides.
General anesthesia are induced including continuous infusion of propofol, 0.5-1 mcg /kg/min remifentanil, and 0.6 mg/kg rocuronium and followed by supraglottic device insertion (i-gel). Propofol are modurated to maintain the bispectral index within the recommended range (45-65). For intraoperative analgesia, 0.1-0.5 mcg /kg/min remifentanil are titrated and 2mcg /kg intravenous fentanyl are administered. All patients are extubated at the end of surgery. Postoperative pain was treated with additional intravenous acetaminophen 10mg/kg. The evaluation of anesthetised dermatomes was performed using ice pack in 0.5 and 2 h after surgery.
Interventions/Control_2
The computer randomly assign patients to low dose quadratus lumborum block group (Group L, n=20) or moderate dose group (Group M, n=20). Patient is blinded from the administration. In Group M, the ultrasound-guided quadratus lumborum block is performed under general anesthesia. 0.4 ml/kg of 0.375% ropivacaine are administered on operation sides.
