Serratus Anterior Plane Block in Pediatric Patients

"After induction of anesthesia, the patients will be put on the lateral position with the diseased side up. A linear ultrasound transducer will be placed in a sagittal plane over the mid-clavicular region of the thoracic cage.~Then counting down ribs till the fifth rib will be identified in the mid-axillary line. The following muscles will be identified overlying the fifth rib: the latissimus dorsi (superficial and posterior),teres major (superior) and serratus muscles (deep and inferior). Under complete sterile conditions, the needle (25 G needle) will be introduced in-plane with respect to the ultrasound probe targeting the plane superficial to the serratus anterior muscle. Then, 2 mg/kg of 0.25% bupivacaine will be injected with continuous ultrasound guidance. In addition to continuous fentanyl infusion"

Continuous fentanyl infusion throughout the surgical procedure.
