Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Neonates with abdominal surgery and quadratus lumborum block<br>0-6 months children with abdominal surgery. After standard induction of general anesthesia, patients will receive 0.5 ml/kg of ropivacaine (2 mg/ml) in a quadratus lumborum block. Ultrasonography will be used to guide the injection. In the postoperative period, pain scores and analgesics consumption will be recorded until the 48th hour post surgery. | Procedure: General anesthesia<br>* Standard general anesthesia<br>Procedure: Quadratus lumborum block<br>* Guided by ultrasonography, injection of 0.5 ml/kg of ropivacaine (2 mg/ml) between the quadratus lumborum muscle and the internal oblique muscle, before skin incision<br>|
