Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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.

Treatment: Other
Comparator / control treatment
Mid-point transverse process to pleura (MTP) block ;
The blocks will perform by same anaesthesiologist immediately before extubation. After identification of the mid point between the transverse process and pleura using parasagittal scan, the needle will advance in-plane from the caudal to cranial direction. Bilevel MTP blocks will perform at T4 and T6 levels with 30 ml 0,375 % bupivacaine (15 ml for each level)

Statistical methods / analysis

Sample size is calculate using previous studies about thoracotomy pain. VAS score as the main parameter (mean standard deviation 1.5-2.0 cm) considering 5% margin of error and 90% power and considering a difference of 2cm as clinically significant. The total sample size was calculated as 60.
The clinical data will collect, verify (mean, median, standard deviation) then analyse using paired and unpaired T-test, Chi-square test, Mann Whitney U-test, Wilcoxon rank sum test, p-value (significant < 0.05).

Summary
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.
