Paravertebral block is an anesthetic method with many advantages applied to inhibit afferent nerve conduction to reduce postoperative pain or provide anesthesia for thoracic trauma surgery.

The 5-year survival rate is up to 80% when breast cancer is diagnosed early and treated at the right time. Along with increasing survival rates, improving a woman's quality of life after breast surgery or mastectomy is equally important.

In breast surgery, nociceptive/inflammatory pain is due to tissue damage, while neuropathic pain is a consequence of damage to the central and peripheral nerves, especially the 2nd to 6th thoracic intercostal nerves. Therefore, pain control is the primary goal of local anesthetic techniques in breast surgery.
