assess and compare the efficacy of pericapsular nerve group block wersus lumber erector spinae plane block in reducing postoperative pain within the first 24 hours after hip surgeries.
after being informed about the study and potential risks. All patients giving written consent will be randomized by double blind manner into 3groups each one containing 23 patients ,PENG group (n =23 ): The patients will receive Pericapsular Nerve Group Block (PENG Block) before positioning for spinal anesthesia.
ESPS group E (n =23 ): The patients will receive Lumbar Erector Spinae Plane Block before positioning for spinal anesthesia.
Control group C(n =23 ): patients received spinal anesthesia without any block.

| PENG | Active Comparator | the patients lied in the supine position. The probe was originally placed in a transverse plane above the anterior superior iliac spine in the ipsilateral surgical site and then counterclockwise rotated about 45 degrees to line up with the pubic ramus. The iliopubic eminence, iliopsoas muscle and tendon, femoral artery, and pectineus muscle were all visible in this view. By an in-plane technique, from lateral to medial, a 22-gauge, 80-mm needle was placed in the musculofascial plane between both the psoas tendon anteriorly and the pubic ramus posteriorly .The local anesthetic medication was delivered after negative aspiration while looking out for proper fluid distribution for a total volume of 20 mL of Bupivacaine 0.25% |
|
| ESPB | Active Comparator | TThe patient was positioned at the lateral decubitus posture in the ipsilateral surgical site. The convex USG transducer was moved from the midline to the side of the operation and positioned 4-6 cm lateral to the L3 spinous process in a longitudinal parasagittal plane. The needle was advanced using the in-plane superior-to-inferior approach. The needle was advanced with the tip introduced up to the plane anterior to the "erector spinae muscle" and the posterior surface of the L3 transverse process. 0.5-1 ml of normal saline was administered for hydrodissection and to ensure proper placement .If there was any resistance during administering local anesthesia, the needle was modified by drawing it back a few millimeters. the prepared local anesthetic solution 20 ml bupivacaine 0.25 % was delivered through the point between both the transverse process and the erector spinae muscle |
