Description of intervention(s) / exposure
Thoracic Paravertebral Block: Thoracic paravertebral block(TPVB) is the technique of injecting local anesthetic along side the thoracic vertebra close to where the spinal nerves emerge from the intervertebral foramen. This produces unilateral, segmental, somatic, and sympathetic nerve blockade, which is effective for anesthesia and in treating acute and chronic pain of unilateral origin from the chest and abdomen. (https://www.nysora.com/regional-anesthesia-for-specific-surgical-procedures/abdomen/thoracic-lumbar-paravertebral-block/) After the most prominent C7, processus spinosus in the cervical region was determined by palpation with the patients in a sitting position with their head slightly tilted forward, the relevant area was cleaned, we marked caudally one by one under US guidance. And 2,5-3 cm lateral of the T4 spinous process was marked as the injection point. At the needle insertion site, 2 mL of 2% lidocaine was infiltrated into the subcutaneous tissue.
After placing the linear US probe on the marked area for paravertebral block application in the longitudinal plane, consecutive transverse processes and the pleura, superior costotransverse ligament, and paravertebral area were determined. With the in-plane technique, an 80 mm 22 gauge peripheral block needle was directed caudally to the cephalad, and the needle tip was advanced into the thoracic paravertebral area until the superior costotransverse ligament was passed. After confirming there was no vascular interference with aspiration, 2-3 mL of 0,9% saline was administered and ventral movement of the parietal pleura was observed to confirm the needle location, and TPVB was administered by injecting 20 mL of 0.25% bupivacaine.
All TPVBs were performed by an anesthesiologist who has been working for at least 5 years.
The approximate time taken to perform the thoracic paravertebral block is 10 min and performed 10 minutes before commencing surgery. The suitability of the block was evaluated with the loss of cold sensation up and down two levels in the mid-clavicular line.

Comparator / control treatment
Erector Spinae Plane Block: Erector spinae plane block (ESPB) is an interfascial plane block first described in 2016 by Forero et al as an effective treatment method for the treatment of thoracic neuropathic pain. Trapezius, rhomboid, and erector spina muscles and consecutive transverse processes were determined with a linear ultrasound (US) probe placed in the longitudinal plane to the area marked. With the in-plane technique, an 80 mm 22 gauge peripheral block needle was directed caudally to the cephalad, and we advanced the needle tip between the anterior fascia of the erector spina muscle group and the T4 vertebral transverse process. After confirming that there was no vascular intervention by aspiration, 2-3 mL of 0.9% saline was administered and simultaneous monitoring of hydro dissection and distribution confirmed the needle location via ultrasonography(USG), ESPB was administered by injecting 20 mL of 0.25% bupivacaine.
All ESPBs were performed by an anesthesiologist who has been working for at least 5 years. The approximate time taken to perform the thoracic paravertebral block is 10 min and performed 10 minutes before commencing surgery. The suitability of the block was evaluated with the loss of cold sensation up and down two levels in the mid-clavicular line.

Statistical methods / analysis
Continuous variables will be presented as mean (±SD) or median (Minimum-Maximum or IQR), depending on whether the data are normally distributed. Data distribution will be evaluated using the Kolmogorov-Smirnov test or the Shapiro-Wilk test. Categorical variables such as gender and type of operation will be analyzed using the ?2 test. Data with normal distribution will be analyzed using Student's T test, and data with non-normal distribution will be analyzed using the Mann-Whitney U test. p< 0.05 was considered significant.
