The Immune Modulation of Bilateral Paravertebral Block and Propofol in Spine Surgery.

Summary

General anesthesia has an important effect on inflammatory cytokines. Inhalational agents as isoflurane and sevoflurane attenuate immune function expressed by neutrophil chemoattractant-1 as well as inflammatory enzyme and also they reduce inflammatory cascade. Total intravenous anesthesia (TIVA) based on using propofol suppresses the inflammatory response caused by surgery to a greater extent because Propofol affects the balance between pro-inflammatory and anti-inflammatory cytokines, increasing production of the anti-inflammatory cytokine IL-10 and at the same time reducing the increase of IL-6 during the perioperative period. It also alters expression of nitric oxide and inhibits neutrophil function. TIVA has many advantages such as; fewer side effects, earlier discharge, better patient satisfaction, faster recovery, less nausea and vomiting and reduced muscle relaxant requirements. Paravertebral block has an important role in the inflammatory and immune response. The paravertebral block can decrease perioperative inflammation and prevent immune suppression. Also, it can attenuate the cytokine response and reduce acute stress response caused by surgery. Decrease inflammation processes, improve surgery result, limit the duration of hospital stay, decrease post-operative fatigue and reduce postoperative complications.
