Inflammatory Effect Comparison Between Fentanyl & Remifentanil in

Status Completed

Clinical Trial Summary

Mastectomy triggers stress and inflammation responses due to tissue trauma. Surgical stress will increase levels of hormones (adrenocorticotropic hormone, cortisol, antidiuretic hormone, epinephrine, norepinephrine, and dopamine) and inflammatory cytokines (Tumor Necrotic Factor-α, interleukin-1, interleukin-2, and interleukin-6) in the body. This causes insulin resistance, gluconeogenesis, and glycolysis, and impaired insulin secretion, which results in hyperglycemia due to intraoperative stress. Intraoperative hyperglycemia increases postoperative complications and mortality. Inhibition of hyperglycemia due to operative stress and stress hormones with good anesthetic management in improving patient outcomes. The choice of opioid type plays an important role in suppressing the perioperative stress and inflammatory response. Opioids are an alternative, besides the use of regional anesthetic techniques which have been proven to suppress the perioperative stress response. Fentanyl is one of the phenylpiperidine synthetic opioids. Large doses of fentanyl can reduce stress responses but also increase side effects, such as hemodynamic instability and decrease T-cell function. Remifentanil provides unique pharmacokinetic benefits through nonspecific esterase enzyme metabolism, so it has a very fast onset and half-life. In addition, remifentanil also provides benefits in reducing the production of interleukin 6 cytokines (IL-6) and tumor necrosis factor α (TNF-α) and inhibits neutrophil migration through the endothelial layer. The stress response to stress and inflammation is directly proportional to the dose of remifentanil given. It is reported that remifentanil can suppress cortisol response according to increasing dose. Winterhalter et al. and Lee et al. reported that remifentanil is better at suppressing the stress response than fentanyl. On the other hand, Bell et al. showed no difference in cortisol and hemodynamic levels between the two groups. The goal of this study is to see if remifentanil provides less increase in serum epinephrine level, norepinephrine level, platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), and blood glucose level at one-hour and 24-hours postoperative in patients undergoing mastectomy surgery under general anesthesia.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
