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… Read more about this study

About this study

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.

Questions about this trial

What is this clinical trial studying?

A study testing Remifentanil and Fentanyl in people with Breast Disease and Anesthesia, run by Udayana University at 1 site in Indonesia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Indonesia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Epinephrine (time frame: 1-hour (postoperative)). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jun 2021.
