Awake Tracheal IntubationPhase 4NCT02673723
The Application of Docozine Combined With Sufentanil for Awake Tracheal Intubation
A Phase 4 study testing Docozine and Saline in people with Awake Tracheal Intubation, run by The First Affiliated Hospital of Anhui Medical University at 4 sites in China.
Trial summary
Mortality associated with difficult airway in anesthesia is up to 30%. So, it is urgent to find a safe and effective method for intubation. Awake tracheal intubation which is used to retain spontaneous breathing is one of the important measures to ensure the safety of the patients with difficult airway in anesthesia.

About this study
Official title: The Application of Docozine Combined With Sufentanil for Awake Tracheal Intubation-a Multiple Center, Randomized, Controlled,Double Blinded Clinical Trial
Mortality associated with difficult airway in anesthesia is up to 30%. So, it is urgent to find a safe and effective method for intubation. Awake tracheal intubation which is used to retain spontaneous breathing is one of the important measures to ensure the safety of the patients with difficult airway in anesthesia.
Sufentanil is used to provide good analgesia and can effectively inhibit the reaction of awake tracheal intubation, however, the outstanding problem is serious respiratory depression after intravenous sufentanil injection. Few study showed that dezocine is a kappa opioid antagonist related to mild respiratory depression and can prevents sufentanil-induced cough during general anesthesia induction.It is necessary to carry out large-scale, multi-center, randomized, controlled clinical study to determine whether dezocine prevents sufentanil-induced respiratory depression and whether dezocine combined sufentanil is a safe and effective method for awake tracheal intubation.

The record lists 4 sites in China. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Sedation assessment (time frame: anesthesia induction). The study lists 5 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 15 Feb 2019.
