Interventions/Control_1

In all the patients, general anesthesia is induced using inhaled sevoflurane in an air-oxygen mixture, including 2mcg/kg fentanyl and 0.6 mg/kg rocuronium, followed by tracheal intubation.
The nerve blocks are performed after intubation prior to incision. In both groups, a high-frequency linear ultrasound probe with a sterile sheath is used to guide needle placement and/or to confirm the spread of the local anesthetic.
The patients in Group Q are placed in the supine position. The bilateral ultrasound guided quardratus lumborum block is performed via the in-plane, transverse, posterior approach described by Branco et al. A needle is inserted from the anterolateral to posteromedial direction, and levobupivacaine 0.25% 0.4 ml/kg is injected into the lumbar interfascial triangle along the dorsal side of the thoracolumbar fascia on one side. The block is then performed on the contralateral side (0.8 ml/kg 0.25% levopivacaine in total).
Surgery is started 15-30 min after performing the block. Any complications occurring intraoperatively are recorded in detail. General anesthesia is maintained by total intravenous anesthesia. Propofol is modulated to maintain the bispectral index within the recommended range (40-60). For intraoperative analgesia, remifentanil is adjusted to maintain the systolic blood pressure and heart rate within 20% of the pre-incision value, and 2 mcg/kg intravenous fentanyl is administered at the time of wound closure. All the patients are extubated at the end of the operation. Intravenous acetaminophen 15 mg /kg is administered to patients in both.

Interventions/Control_2

In all the patients, general anesthesia is induced using inhaled sevoflurane in an air-oxygen mixture, including 2mcg/kg fentanyl and 0.6 mg/kg rocuronium, followed by tracheal intubation.
The nerve blocks are performed after intubation prior to incision. In both groups, a high-frequency linear ultrasound probe with a sterile sheath is used to guide needle placement and/or to confirm the spread of the local anesthetic.
The patients in Group QR are placed in the supine position. First, the bilateral ultrasound guided quardratus lumborum block is performed via the in-plane, transverse, posterior approach described by Branco et al. A needle is inserted from the anterolateral to posteromedial direction, and levobupivacaine 0.25% 0.4 ml/kg is injected into the lumbar interfascial triangle along the dorsal side of the thoracolumbar fascia on one side. The block is then performed on the contralateral side (0.8 ml/kg 0.25% levopivacaine in total). Then, the bilateral ultrasound guided rectus sheath block is performed via the in-plane, transverse approach. A needle is inserted into the rectus sheath, and levobupivacaine 0.25% 0.2 ml/kg is injected on one side. The block is then performed on the contralateral side (0.4 ml/kg 0.25% levopivacaine in total).
Surgery is started 15-30 min after performing the block. Any complications occurring intraoperatively are recorded in detail. General anesthesia is maintained by total intravenous anesthesia. Propofol is modulated to maintain the bispectral index within the recommended range (40-60). For intraoperative analgesia, remifentanil is adjusted to maintain the systolic blood pressure and heart rate within 20% of the pre-incision value, and 2 mcg/kg intravenous fentanyl is administered at the time of wound closure. All the patients are extubated at the end of the operation. Intravenous acetaminophen 15 mg /kg is administered to patients in both.
