About

Regional anesthesia is a popular anesthetic method in patients who will undergo an inguinal hernia operation. Researchers known that pain in the operating area is a complaint that impairs the quality of life for patients in the long term after the operation. In addition to regional anesthesia, has planned to investigate the effects of applying another drug near the surgery area on pain that may develop in the long term.

Full description

Post-operative chronic pain can be defined as the neuropathic-characterized pain persisting at least 3 months after the surgery despite healing of the operation area.

However, it is still uncertain if the underlying physio-pathologic mechanism is due to intraoperative direct nerve injury or it is resulting from indirect nerve injury caused by inflammatory mesh. Post-operative chronic pain restricts the daily activities, causes anxiety and depression, increases use of analgesics and imposes a serious economic burden by increased use of health services and medical treatment. For this reason, today post-operative chronic pain is considered as an important complication of surgery. Researchers can list the risk factors of pain development as; age, weight, preoperative and postoperative pain, surgical method, recurrence, anesthesia method. Various oral non-steroid and/or opioid agents have been used in chronic pain treatment but nowadays interest in regional anesthesia approaches is increasing due to increased systemic side effects. Aim in this study is to evaluate the effects of postoperative ilioinguinal block implementation on chronic pain in patients who will undergo inguinal hernia operation with spinal anesthesia.
