Summary

the study aims to compare the analgesic efficacy of erector spinae plane block versus thoracic paravertebral block after open nephrectomy surgery.

Conditions

  • Pain, Postoperative

Interventions

PROCEDURE

erector spinae block

ultrasound probe is placed parallel to the vertebral spine at T4 level and shifted 3 cm laterally to obtain the appropriate visualization. Under aseptic precautions, the needle is inserted and advanced perpendicular to the skin in all planes to contact the transverse process of the vertebra at a variable depth of 2-4 cm from the skin depending on the build of the individual. At this point, the needle tip lies between the erector spinae muscle and transverse process. After negative aspiration, 20 ml of 0.25% bupivacaine is administered in cephalad and caudal directions.

PROCEDURE

thoracic paravertebral block

ultrasound probe is placed parallel to the vertebral spine at T4 level and shifted 2-3 cm laterally to obtain the appropriate visualization. Following the identification of pleura, transverse process and paravertebral space, the needle is inserted cranial to caudal direction using in-plane approach . After confirming the displacement of pleura with 0.5-1 ml of local anesthetic (LA), 20 ml of 0.25% bupivacaine is administered for the block.
