Immunomodulatory Effects of Dexmedetomidine Infusion

Immunomodulatory Effects of Dexmedetomidine Infusion After Laparoscopic Major Abdominal Surgeries: Randomized Controlled Study

Anesthetic management may affect both immunostimulatory and immunosuppressive mechanisms directly by modulating immune cell function or indirectly by attenuating the stress response, Thus, the choice of anesthetic technique may affect clinical outcomes by perturbing the balance between pro- and anti-inflammatory responses,anesthetics favoring this delicate balance are thus desirable as their use may reduce postoperative complications and mortality
