Surgical repair of the hip can be extremely painful and is associated with considerable postoperative pain in children despite the use of systemic opioids. These patients may benefit from neuraxial analgesia in adjunction with general anesthesia. The reported advantages of this technique include decreased opiate exposure, decreased time in the post-anesthesia recovery room, decreased hospital stay, reduce the post-operative morbidity, provide early mobilization. Regional anesthetic techniques seem to be a better choice for improving acute pain management in these patients, with fewer adverse effects.

Regional anesthetic techniques seem to be a better choice for improving acute pain management in these patients, with fewer adverse effects. The erector spinae block is a recently described ultrasound-guided technique in which local anesthetics is injected into a fascial plane between the tips of the thoracic transverse processes and the overlying erector spinae muscle (longissimus thoracis). Pericapsular nerve group (PENG) block has been recently recommended by Girón-Arango et al. for use as postoperative analgesia in hip surgeries. It is a new regional anesthesia technique in the region between the anterior inferior iliac spine (AIIS) and ilio-pubic eminence (IPE). The anterior capsule is the most richly innervated section of the joint suggesting these nerves should be the main targets for hip analgesia.

Under ultrasound guidance, patients of this group will receive (0.5ml/kg) plain bupivacaine 0.25%with adrenaline 2.5 µg/ml injected beneath the erector spinae muscle sheath at the level of the transverse process of the second lumbar vertebrae

Under ultrasound guidance, patients of this group will receive (0.5ml/kg) plain bupivacaine 0.25%with adrenaline 2.5 µg/ml injected as the tip of the needle in the musculofascial plane between the psoas tendon anteriorly and the pubic ramus posteriorly

the patient will be placed in the lateral position with the surgical side up for performing erector spinae plane block. After skin preparation, superficial (5-12 MHz) ultrasound transducer will be placed in a longitudinal orientation 1-2cm lateral to the midline at the sacral level. The L2 level will be identified by counting upward from the sacrum. Following identification of the erector spinae muscle (ESM) and transverse process, a 21 G needle will be inserted deep to the erector spinae muscle (ESM) in a cranio-caudal direction. After negative aspiration, the correct needle position will be confirmed with the administration of 0.5-1ml LA. A total volume of 0.5 mL/kg local anesthetic solution will be injected interfascial plane between erector spinae muscle and transverse process for block performance.

the patient will be in supine position. The ilio-pubic eminence (IPE), the iliopsoas muscle and tendon, the femoral artery, and pectineus muscle will be visualized using a linear ultrasound probe. A 22-gauge, 50-mm needle will be introduced in a lateral to medial fashion in an in-plane approach to place the tip of the needle in the musculofascial plane between the psoas tendon anteriorly and the pubic ramus posteriorly. Following negative aspiration, a total volume of 0.5 mL/kg local anesthetic solution will be injected.

Time to first rescue analgesic requirement: measured from the end of surgery till patient require analgesia.

Total analgesic consumption If pain score more than 3, the child will be given intravenous morphine as rescue analgesia will be given in a dose 0.1mg/kg.

Inclusion Criteria: Children of both genders American Society of Anaestheologists (ASA) physical activity I, II aged more than one year admitted for elective pediatric hip surgery Exclusion Criteria: Children with severe systemic disease with American Society of Anaestheologists (ASA) III or IV, children with previous neurological or spinal disorders, coagulation disorder, infection at the block injection site, history of allergy to local anesthetics bilateral hip surgery.
