Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Randomization was divided into two groups by using closed envelope method. Postoperative pain scores at rest at 1, 2, 4, 6, 8, 10, 12, and 24 hours with VAS (0 = no pain, very severe pain = 10) using Visual Analogue Scale was made. VAS at rest and movement (coughing and taking a deep Breath) were evaluated. Patients with VAS\> 4 received additional analgesics.

block group

Paravertebral group at Thoracic 9-10 vertebrae level with an in-plane technique advanced ultrasound guided 10 ml bupivacaine hydrochloride (Marcaine 0.5%, Astra Zeneca) in 20 ml volume was enjected in the paravertebral area with real-time visualisation It was observed that the local anesthetic drug spread on the pleura and the pleura was pushed. All blocks were performed by the same experienced anaesthesiologist.

Control group

Conventional analgesia methods were applied to the control group. Control group was relieved by dexketoprofen 50mg intravenously. If the patient was not relieved with dexketoprofen and VAS score \>4, tramadol 1 mg kg-1 was administered intravenously.
