About this study

Official title: Comparison of the Effect of Xylometazoline and Cocaine on Epistaxis When Administered as Local Vasoconstrictors Prior to Nasal Intubation

The objective of this study is to compare xylometazoline and cocaine's effect on minimizing epistaxis when administered as a local vasoconstrictor prior to nasal intubation.

The investigators hypothesize that there will be a lower bleeding score in the group receiving xylometazoline as compared with the group receiving cocaine.

Read the detailed description

When performed by trained personnel nasotracheal intubation is a safe and effective technique for attaining a secure airway in preparation for surgery of the head and neck. Upon intubation the nasal mucosa must be sufficiently lubricated and decongested in order to minimize the risk of epistaxis. For this purpose several topical agents are suggested, the most common being adrenaline, cocaine and oxymetazoline/xylometazoline in varying combinations and dosages. As such, no broad consensus or guidelines currently exist on a single recommended drug for the prevention of epistaxis induced by nasal intubation.

In 1990 Katz et. al performed a study comparing three interventions: cocaine, lidocaine with epinephrine and oxymetazoline in regard to the prevention of epistaxis on nasotracheal intubation. This study included 14 patients in each of their three groups and the authors concluded that oxymetazoline and cocaine were equally effective. However, due to their limited sample size that study was clearly inconclusive, and the investigators wish to repeat such a comparison.

The trial drug xylometazoline is commonly used in Danish operating rooms under the registered trademark Zymelin. It is an adrenergic drug typically used for decongestion of the nose and its local vasoconstrictive effect occurs after a few minutes and lasts 10-12 hours. The drug is readily available without prescription and in theory the patient could administer this themselves on their way to surgery. Oxymetazoline used by Katz et. al and xylometazoline used in Danish hospitals have similar decongestive effects as oxymetazoline is a derivative of xylometazoline. The two drugs share pharmacodynamics varying only on receptor subtype affinity in their direct action on alpha-adrenergic receptors in the arterioles of the nasal mucosa. Both drugs result in vasoconstriction that leads to decreased blood flow and thereby decongests the nose.

The second trial drug cocaine is also routinely used. It is a magistral formula used especially due to its unique combination of both vasoconstrictive and analgesic properties. It is a potent vasoconstrictor through its ability to inhibit the reuptake and metabolism of catecholamines, which then in greater concentration produce adrenergic effects. Uniquely cocaine also binds to and blocks axonal membrane sodium channels, thus interfering with the propagation of action potentials and thereby exerting an analgesic effect. When administered in doses thought to avoid systemic effects, cocaine is a safe local anesthetic agent. The recommended dosage varies considerably throughout the literature with safe doses ranging between 1.5-3.0 mg/kg.

The investigators wish to compare the effects of xylometazoline and cocaine regarding their prevention of epistaxis during and immediately after nasal intubation.

What participants receive

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

  • Xylometazoline 0,1%Drug

    Also called Zymelin

    1 ml of 0,1% xylometazoline diluted with 1 ml of 0,9% isotonic saline solution given as a nasal spray

  • Cocaine 4%Drug

    Also called Cocaine hydrochloride 4%

    2 ml of 4% cocaine given as a nasal spray

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Bleeding score

    Evaluation of epistaxis measured on a predefined scale of 0-3:

    1. No sign of bleeding
    2. Blood only on the tracheal tube
    3. Pooling of blood in the pharynx
    4. Bleeding to the extent that it complicates intubation

    Measured: Immediately following nasal intubation

Secondary outcomes (2)
  1. Qualitative measurements of cocaine's main metabolite benzoylecgonine in saliva

    For cocaine-group only, saliva samples will be obtained and analyzed on the DrugTest 5000 machine used by the Danish Police Force in order to evaluate pharmacokinetics.

    Measured: Immediately prior to nasal intubation, 60 minutes after administration of cocaine and 24 hours after administration of cocaine.

  2. Quantitative measurements of cocaine in whole blood.

    In the cocaine group only, blood samples will be drawn and analyzed for the presence of cocaine in order to evaluate pharmacokinetics.

    Measured: Immediately prior to nasal intubation, 60 minutes after administration of cocaine and 24 hours after administration of cocaine.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Xylometazoline 0,1% and Cocaine 4% in people with Epistaxis, run by Copenhagen University Hospital, Rigshospitalet at 1 site in Denmark.

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 12 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 27 Mar 2023. 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 Denmark. 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. 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?

Bleeding score (time frame: Immediately following nasal intubation). 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 27 Mar 2023.
