- Age: 19 to 80 years old
- ASA (American Society of Anesthesiologists Class) I-?
Exclusion criteria: - Patients who have difficulty in obtaining information and effects of nerve block related to the study due to cognitive decline.

Intervention(s)

Procedure/Surgery : Following thoracic epidural block, which is considered the standard treatment for postoperative pain control, for patients who underwent video assisted thoracic surgery, paravertebral nerve block has been proven to be effective in pain control. Recently, a new technique called erector spinae plane block has been introduced and the frequency of its use is gradually increasing. The difference between the two procedures is the target point where the tip of the epidural needle inserted under ultrasound guidance is located.
In the case of paravertebral nerve block, the needle tip is placed in the paravertebral space located between the transverse process, superior costotransverse ligament, intertransverse ligament, and the pleural structure, and then a local anesthetic is administered. In the case of erector spinae plane block, after checking the trapezius, rhomboids, erector spinae, and transverse processes, place the needle tip under the erector spinae muscle and administer a local anesthetic.

Primary Outcome(s)

VAS (Visual analog scale) of each group after surgery

Secondary Outcome(s)

Total consumption of opioids (Morphine equivalent dose)

Analgesics taken by the patient in addition to the nerve block
