Axillary Brachial Plexus Block Using 0.25% Bupivacaine Versus Using 0.19%Bupivacaine in Pediatrics

Postoperative pain is a common manifestation in orthopedic patients, mainly due to intraoperative tissue damage and inadequate intraoperative pain assessment and management .Axillary brachial plexus block provides motor and sensory block with the distribution of the median, radial, ulnar and musculocutaneous branches so can be conducted with upper limb orthopedic surgery in hand, rest and elbow surgery distal to the cubital fossa . In this study the investigators will investigate (0.19%) and (0.25%) bupivacaine for postoperative motor power recovery and post-operative analgesic efficacy in ultrasound guided axillary brachial plexus block among pediatric patient undergoing below elbow orthopedic surgery.
