The aim of the study is to compare postoperative analgesia in pediatric patients undergoing inguinal hernia repair by comparing the efficacy of ultrasound guided paravertebral block versus ultrasound guided erector spinae plane block.
* To assess the total amount of rescue analgesic consumption in the first 24 hours post-operatively in each group. * To measure the time of first request of rescue analgesia and to assess pain intensity at rest (static) and after movement or coughing (dynamic) using 10 points Modified Objective Pain Score (MOPS). * To record the incidence of complications (hematoma, local anesthetic toxicity, pneumothorax, infection, hypotension, epidural or intrathecal spread). * Over all parent's satisfaction: The parents will be asked to rate the overall degree of satisfaction of the analgesia by using a 5-points likert-like verbal scale (1 = very dissatisfied analgesia, 2 = dissatisfied analgesia, and 3 = neutral, 4=satisfied analgesia, and 5=very satisfied analgesia).

after sterilization and identifying the level of T10 ,linear ultrasound probe will be placed in the midline over the spinous process at the chosen level, then the probe will be moved laterally to view the lamina and hyperechoic transverse process ,the pleural should be visible as a bright white line .The needle should be inserted in -plane from lateral to medial and the needle tip should end in a hypoechoic triangular space. Correct needle placement should be confirmed by anterior displacement of pleura with injection of small volume of saline then 0.5 ml/kg of a mixture of 0.25 ℅ bupivacaine and 1℅ lidocaine (1:1) will be injected
After sterilization, the linear ultrasound probe will be placed over transverse process of T10 ,after optimizing the image in sagittal or transverse scanning ,A 50 mm 22-G needle will be placed under the erector spinae muscle in -in plane orientation until it contacted T8 transverse process in the cranial caudal direction ,after hydro dissection and confirmation that the tip of the needle is between the transverse process and the fascia of the erector spinae muscle group, 0.5 ml/kg of a mixture of 0.25 ℅bupivacaine and 1℅ lidocaine (1:1) will be injected

Pain intensity at rest (static) and after movement or coughing (dynamic)
by using 10 points Modified Objective Pain Score (MOPS)(0=no pain, 1-3=mild pain, 4-6=moderate pain, and 7-10= sever pain)
Time frame: 0 minutes immediate postoperative ( on arrival to PACU), 30 minutes, 1hs, 2hs, 4hs, 8hs, 12 hrs and 24hs postoperatively
The time to first request of rescue analgesia (Ibuprofen)
the time from giving block till time of first request of ibuprofen when MOPS \> 3 at rest or after movement
Time frame: for 24 hours postoperative
The total number of patients requiring additional dose of intraoperative fentanyl.
Number of patients receive additional dose of intra operative fentanyl ( increase in the mean blood pressure or heart rate 20% above base line readings, fentanyl in a dose 0.5 mcg/kg will be given to the patient)
Time frame: during operation period
To record the incidence of complications
