Brief Summary

The effects of anesthesia and surgery can lead to stress responses that result in hormonal and metabolic changes in the body. The immune system and the nervous system communicate both ways, and it was found that nociception and proinflammatory cytokines play a joint regulatory role, i.e., increased production of proinflammatory cytokines can worsen the pain. Major surgery can trigger the release of cytokines such as IL-1, IL-6, and TNF-α.

Outcome Measures

Primary Outcomes (6)

  • Serum CRP level

    Serum C-reactive protein level

    1-hour before surgery

  • Serum CRP level

    Serum C-reactive protein level

    24-hours after surgery

  • serum neutrophil-count

    serum neutrophil-count (from a complete blood count test)

    1-hour before surgery

  • serum neutrophil-count

    serum neutrophil-count (from a complete blood count test)

    24-hours after surgery

  • VAS (visual analog score)

    minimum=0; maximum=10; higher score corresponds to more severe pain

    first 24 hours after the surgery

  • morphine consumption (mg)

    total morphine consumption in 24 hours after the surgery

    first 24 hours after the surgery
