About this study

Patients with cardiac channelopathies needing restorative dental treatment will be included in two sessions of the study, using local dental anesthetic: lidocaine 2% with epinephrine and lidocaine 2% without vasoconstrictor. The safety of the use of two cartridges (3.6 mL) will be evaluated. The patients will be their own control and will be assessed by Holter monitoring for 28 hours, blood pressure measurement and anxiety measuring.

Read the detailed description

Patients of Heart Institute of the University of São Paulo with inherited cardiac channelopathies will be included, considering the criteria for inclusion and non-inclusion, after reading and signing the informed consent.

They will undergo dental restorative treatment in two sessions, in the morning period, with an interval of at least seven days (wash-out) between them, and the patients will be their own control.

In the first session, after randomization, patients will receive lidocaine 2% without vasoconstrictor (LSA) or lidocaine 2% with 1: 100,000 epinephrine (LCA) (cross-over), resulting in two conditions: with adrenaline and without adrenaline.

The randomization of the anesthetic solution will be performed by the main researcher, being blind to the performer researcher and to the patient.

The injected volume will be 3.6 mL (2 cartridges) of the anesthetic solution, using blocking technique of the inferior alveolar nerve.

The patients will be monitored by Holter for 28 hours starting one hour before the procedure, for registration and analysis of cardiac electrical activity during the two sessions. Blood pressure will be monitored with digital sphygmomanometer and anxiety will be measured with Facial Image Scale, both on three occasions: at the beginning of the baseline periods, before starting application of anesthesia and at the end of the proceedings. The results will be analyzed statistically.

Questions about this trial

What is this clinical trial studying?

A study testing Dental restorative procedure in people with Channelopathies and Brugada Syndrome, run by University of Sao Paulo General Hospital at 1 site in Brazil.

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 9 Apr 2024. 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 Brazil. 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.

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?

No sustained ventricular tachycardia (time frame: during dental procedures). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03182777, which also lists 25 linked publications.

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 9 Apr 2024.
