About this study

Sufentanil has the advantages of fast onset time, strong analgesic function and cardiovascular stability, and is widely used during general anesthesia induction. However, sufentanil can cause cough during induction of general anesthesia. Different studies have reported that the incidence of sufentanil-induced cough ( SIC ) during anesthesia is 16-42 %. This pathological condition may lead to damage to the central nervous system, increase the risk of reflux and aspiration, increase intracranial pressure and intraocular pressure, and endanger patients with cerebral aneurysms and ocular trauma. Therefore, at the moment of advocating comfortable anesthesia medical services, sufentanil-induced cough response is a problem that clinical anesthesiologists need to focus on and urgently solve. It has been reported that ketamine can reduce the incidence of cough caused by opioids. Esketamine is a pure dextro-enantiomer of ketamine and an NMDA antagonist with potent analgesic and bronchodilator effects. In this study, Dixon sequential method was used to study the median effective dose ( ED50 ) of intravenous esketamine pretreatment to prevent sufentanil-induced cough, and to explore the effect of age on ED50. To provide reference for clinical rational selection of esketamine dose.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EsketamineDrug

    The initial dose of esketamine was set as 0.06 mg / kg, and the injection time of esketamine was 5 s. One minute after injection of esketamine, sufentanil 0.4 μg / kg was injected within 5 s, and the number of coughs within 1 min after injection was recorded. According to the evaluation of sufentanil-induced cough, the dose of esketamine was adjusted. If the patient had no cough ( negative reaction ), the dose of esketamine in the next patient was reduced until the cough reaction occurred. If the patient had a cough reaction ( positive reaction ), the dose of esketamine in the next patient was increased until the cough disappeared. The dose ratio of adjacent esketamine was 1.1. Each group was selected from the previous patient with positive reaction until the 7 groups of positive and negative reactions appeared alternately, and the test was completed.

Questions about this trial

What is this clinical trial studying?

A study testing Esketamine in people with Sufentanil and Esketamine, 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 1 inclusion and 10 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 12 Apr 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 cough (time frame: an average of 1 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 12 Apr 2023.
