Caudal blockade (CB) is one of the most frequently performed regional anaesthetic techniques in children. It's an efficient way to offer perioperative analgesia for painful sub-umbilical interventions but with high incidence of motor block and urinary retention. In one study, psoas compartment block was associated with less morphine comsumption and prolonged duration of analgesia compared to single-shot caudal Block in small children undergoing open hip reduction/osteotomies. Ultasound guided anterior Quadratus lumborum block (AQLB) provides unilateral analgesia to the nerves between the psoas muscle (PM) and the quadratus lumborum muscle (QLM). The first pediatric study evaluating Quadratus lumborum block is encouraging .
The first pediatric study evaluating Quadratus lumborum block is encouraging. To the best of the investigator's knowledge, there are no previously published data comparing the AQLB with other regional techniques in infants undergoing hip surgery.
The aim of this prospective randomized study was to compare the analgesic effects between AQLB and CB in children undergoing unilateral open hip reduction/osteotomies for hip dislocation.
Patients were randomly assigned, into 1 of 2 groups, namely, group CB (n = 20) and group AQLB (n = 20).
Preoperatively all children were premedicated by using oral midazolam (0 .5mg/kg).
anesthesia was induced with 3 to 4% sevoflurane and 50% with 60% nitrous oxide in oxygen.Then fentanyl 3 μg/kg and Propofol 1 - 2mg/Kg were administered for anesthesia induction. Airway was secured with endotracheal tube placed in the mouth facilited by 0.15 mg/kg cistracurium. Anesthesia maintenance was performed with sevoflurane 2% in 50% nitrous oxide.
AQLB and CB were done with 1 ml/kg, 0.25% Ropivacaine (maximum dose limited to 20 ml)
Postoperative follow-up:
All patients received 15 mg/kg paracetamol before extubation. Tramadol 2 mg/kg intravenous was planned as rescue analgesia when CHEOPS score was more than 3. Supplemental IV tramado, 1 mg/kg could be added if necessary every 6 hours.

| CAUDAL BLOCK | Active Comparator | Sonosite machine (M-Turbo) equipped with a large bandwidth, a multifrequency linear probe (6-19 MHz) and needle of diameter and length respectively between 22G and 25G, 35mm and 40mm according to the child's size (Braun).The patient is positioned laterally with their hips flexed to 90°. The sacral hiatus is forming with the two posterior superior iliac spines an equilateral triangle. The puncture is performed between the two sacral cornuae. The sacrococcygeal ligament gives a perceptible 'pop' when crossed. After crossing the sacro-coccygeal ligament, the needle is redirected 30° to the skin surface, and then advanced a few millimeters into sacral canal. After verifying absence of spontaneous reflux of blood or cerebrospinal fluid, slowly injection of Ropivacaine 0.25% 1ml/ kg |

| anterior Quadratus lumborum block | Experimental | Sonosite machine (M-Turbo) equipped with a large bandwidth, a multifrequency linear probe (6-19 MHz) and a 22G, 50-mm, insulated facet type needle (BBraun Stimuplex Ultra 360°). Patients were placed in the lateral position, a probe was placed transversely to the abdominal flank. The needle was inserted using an in-plane technique and was preceded further into the fascia between the QLM and PM. Following confirmation of the correct space with the administration of 0.5-1 ml local anesthetic, block was induced with 1 ml/kg, 0.25% Ropivacaine, |
