Brief summary
Thoracotomy surgery is one of the most painful surgical procedures followed by intense, acute and chronic pain. The thoracic paravertebral block (PVB) is known to be the gold standard for acute post-thoracotomy analgesia for a long time . In recent years, many novel posterior thoracic wall blocks have been described as alternatives for PVB in order to avoid possible nerve-vessel damages and pneumothorax such as Erector Spinae Plane Block (ESPB) and mid-point transverse process to pleura (MTP) block .To date, there are no studies that compare the efficacy of ESP block and MTP block. The objective of this randomized study is to compare the analgesic efficacy of these two techniques in the control of acute post-thoracotomy pain.
Interventions
Erector Spinae Plane Block (ESPB) ;
The blocks will performed by same anaesthesiologist, before extubation. Linear USG probe will use to display erector spinae muscles and T4 transverse proces approximately 3-4 cm lateral from the midline. A 22-gauge, 80-mm block needle will advance (in plane) in cranio-caudal direction until touch the T4 transverse process under the erector spinae muscle.
Bilevel ESP blocks will perform at T4 and T6 levels with 30 ml 0,375 % bupivacaine (15 ml for each level
