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.
Intervention code [1] 316853 0
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).
