Summary

To compare between the intra muscular quadratous lamborum and the Trans muscular quadratous lamborum in pediatric population under going abdominal surgeries regards to first request of rescue analgesia, degree of pain relief, effect on hemo dynamic stability and incidence of complications.

Detailed description

The investigators hypothesized that an ultrasound guided quadratous lamborum block would prove successful peri-operative analgesia for abdominal surgeries in pediatric patients, and that Intra muscular quadratous lamborum is non inferior to Trans muscular blockade with the advantage of being safer (away from the peritoneum and retroperitoneal organs) and with the assumption that sarcolemmal layer in pediatrics should not resist the diffusion of the injectant from within the muscle out, to reach the inter fascial plane where the targeted nerves are found and cause an efficient blockade.

Conditions

• Pain, Acute

Interventions

Type	Name	Description
PROCEDURE	Bilateral Ultrasound-Guided Transmuscular Quadratus Lumborum Block.	A 22 G echogenic needle will be inserted in plane from the posterior (medial) end of the probe and directed for the fascial plane between the Quadratus Lumborum and the Psoa Major muscles through the Quadratus Lumborum muscle. Once the needle is confirmed in correct location, 1 mL of saline will be injected after negative aspiration. Then 0.5 mL/Kg of bupivacaine 0.25% will be injected. The spread of the injectate should be observed to distribute within this plane. This technique will be repeated to the other side.
PROCEDURE	Bilateral Ultrasound-Guided intra smuscular Quadratus Lumborum Block.	A 22 G echogenic needle will be inserted in plane from ventral (lateral) edge of the probe and advanced until penetration of QL muscle fascia is observed. Once the needle is confirmed in correct location, 1 mL of saline will be injected after negative aspiration. Then 0.5 mL/Kg of bupivacaine 0.25% will be injected. The spread of the injectate should be observed to distribute within this plane. This technique will be repeated to the other side.
PROCEDURE	Control	Conventional analgesia
