Ultrasound- Guided Mid Point Transverse Process to Pleura Block

After marking the level of the incision by surgeon (commonly T11 -T12) The patient will be situated in modified lateral position with flank region over kidney elevated to wide the space between iliac crest and subcostal margin, the block area will be sterilized with povidine-iodine, and high -frequency linear ultrasound probe will be placed oblique parasagittally lateral to the spinous process of T11 or T 12 and scanning till appearance of transverse process, 100-mm short bevel echogenic needle (Vygon) will be inserted in plane from cranial to caudal direction. The desired end point of the needle tip will be the midpoint of the line between the posterior border of transverse process and the pleura.After negative aspiration to avoid intravascular injection levobupivacaine 0.5% and dexamethazone 4mg total volume 21ml will be injected
