Supra Inguinal Fascia Iliaca Block Versus Ultrasound-guided Caudal Analgesia for Pediatrics Undergoing Anterior and Lateral Thigh Surgeries: A Randomized Controlled Trial

With the patient in the proper position, the skin is disinfected and the transducer positioned to identify the femoral artery and the iliopsoas muscle and fascia iliaca. The transducer is moved laterally until the sartorius muscle is identified. After a skin wheal is made, the needle is inserted in-plane

The caudal block will be performed by visualizing the sacral hiatus at the level of the sacral cornu after placing the probe transversely obtaining a short axis view, two hyperechoic lines will appear between the sacral cornu the superficial line is the sacrococcygeal ligament
