Trial summary

Since its introduction in 1973, etomidate has been widely used in clinical anaesthesia, especially in haemodynamically unstable patients, as a new anaesthetic induction drug with the advantage of low circulatory and respiratory depression. Read more about this study

About this study

Since its introduction in 1973, etomidate has been widely used in clinical anaesthesia, especially in haemodynamically unstable patients, as a new anaesthetic induction drug with the advantage of low circulatory and respiratory depression. When administered via intravenous injection, etomidate can cause adverse effects such as injection pain and myoclonus. The incidence of myoclonus is still reported to be as high as 50-80%. Myoclonus caused by etomidate may cause discomfort during induction of anaesthesia and reduce perioperative satisfaction, and may lead to syringe dislodgement, extravasation of the injected drug, swelling at the injection site, delayed induction of anaesthesia and, in severe cases, cardiovascular adverse events. Therefore, the myoclonus and limb retraction reactions caused by etomidate are a key concern for clinical anaesthesiologists and need to be addressed at a time when comfort anaesthesia is being promoted. The aim of this study was to reduce myoclonus produced by etomidate injection during induction of general anaesthesia in surgical patients and to investigate the half effective dose of remifentanil to reduce etomidate myoclonus.

Study groups in NCT05754762
Study groupRoleWhat they receive
Age range of 18 to 40 years oldsExperimentalBased on previous literature and preliminary test results, the initial dose of pre-injection remifentanil is set at 1ug / kg. The dose of remifentanil is based on the patient's degree of myoclonus. If there is no myoclonus (negative response), the dose of remifentanil is reduced for the next patient until the patient develops myoclonus. If there is myoclonus (positive response), the dose of remifentanil will be increased in the next patient until the patient is free of myoclonus.
Receives: Drug: Remifentanil
Age range of 41 to 55 years oldsExperimentalBased on previous literature and preliminary test results, the initial dose of pre-injection remifentanil is set at 1ug / kg. The dose of remifentanil is based on the patient's degree of myoclonus. If there is no myoclonus (negative response), the dose of remifentanil is reduced for the next patient until the patient develops myoclonus. If there is myoclonus (positive response), the dose of remifentanil will be increased in the next patient until the patient is free of myoclonus.
Receives: Drug: Remifentanil
Age range of 56 to 70 years oldsExperimentalBased on previous literature and preliminary test results, the initial dose of pre-injection remifentanil is set at 1ug / kg. The dose of remifentanil is based on the patient's degree of myoclonus. If there is no myoclonus (negative response), the dose of remifentanil is reduced for the next patient until the patient develops myoclonus.

Questions about this trial

What is this clinical trial studying?

A study testing Remifentanil in people with Etomidate and Myoclonus, run by Yangzhou University.

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 2 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 6 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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?

Results are not available in the source record.

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?

The presence of myoclonus (time frame: an average of 2 minutes). 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 6 Mar 2023.
