Ultrasound-Guided Combined Pericapsular Nerve Group Block and Lateral Femoral Cutaneous Nerve Block Versus Caudal Block for Postoperative Analgesia in Pediatric Hip Surgeries. A Randomized Controlled Study.

All children will be assessed clinically, and investigations will be done to exclude the exclusion criteria mentioned above. Laboratory works needed: complete blood count (CBC), prothrombin time, concentration, partial thromboplastin time. Midazolam (0.5mg/kg) will be given orally to each child in both groups as a premedication half an hour before the procedure.

General anesthesia will be induced in a supine position under standard basic monitoring of vital signs with inhalational anesthetic using (100%) O2 + Sevoflurane.

Group C will receive caudal analgesia Bupivacaine 0.25% at a dose of 1 ml/kg. Group B will receive PENG block Bupivacaine 0.25% at a dose of 1 ml/kg and lateral femoral cutaneous nerve block Bubivacaine 0.25% at 0.1 ml/kg.

After receiving the block, a surgical incision will be done after 15 minutes. Continuous recording of heart rate and blood pressure will be carried out from the moment of injection at timely intervals intra-operative. Intra-operatively, an increase in hemodynamics in response to the skin incision by more than 30% from baseline values 5 min after intubation or thereafter is managed by intravenous administration of fentanyl 1 µg/kg to a maximum dose of 2 µg/kg. Postoperative pain assessment using the FLACC score will then follow for 24 hours.
