Brief summary

Retrolaminar block (RLB) and erector spinae plane block (ESPB) are alternative approaches to paravertebral block (PVB) and are advantageous in that they are easier and safer techniques compared with the traditional PVB. These blocks are considered to be compartment blocks or interfascial plane blocks. In these approaches, local anesthetics are assumed to penetrate the superior costotransverse ligament and reach the paravertebral space, although the needle tip is not advanced into the paravertebral space. the study aim to evaluate and compare the analgesic efficacy of retrolaminar plane block and erector spinae plane block.

Interventions

PROCEDUREretrolaminar block

curved probe will be placed 1-1.5 cm lateral to the target spinous process after identification of the lamina, the needle will be advanced caudally until it contacts the lamina

PROCEDUREESPB

curved probe will be placed 2-3 cm lateral to the spine using a sagittal approach at the level of T8. After identification of erector spinae muscle and transverse processes, the needle will be inserted deeply into the erector spinae muscle.
