About this study

Official title: Intravenous Or Topical Lidocaine And Neuromonitoring in Thyroid Surgery (IOLANT Study)

The aim of this study is to test the hypothesis that the quality of recovery with topical lidocaine is better than placebo.

Read the detailed description

The use of neuromonitoring in thyroid surgery imposes a number of special demands for anaesthetic management. Such demands include avoiding muscle relaxation and local anaesthesia. Maintaining a balance between the risk of awakening during surgery and excessively deep anaesthesia in fast track surgery is an important task for the anaesthesiologist.

Mild anaesthesia in the absence of muscle relaxation increases the risk of developing laryngeal reflexes, coughing during surgery, while excessively deep anaesthesia slows down recovery after surgery and increases the risk of arterial hypotension. The frequency and duration of arterial hypotension, as well as the depth of anesthesia assessed by the Bispectral index, are independent risk factors for postoperative cardiovascular complications and long-term mortality. On the other hand, coughing in response to irritation of the endotracheal tube during recovery from anesthesia is recognized as a risk factor for respiratory and cardiovascular complications, as well as postoperative wound insufficiency.

Optimization the anesthesia by intravenous infusion of lidocaine can improve anesthesia controllability, hemodynamic stability and overall anesthesia recovery rates. Local use of lidocaine, including filling the endotracheal tube cuff with its alkalinized solution, has also been shown to be effective in reducing the frequency of laryngeal reflexes upon awakening after surgery of varying duration. However, the efficacy and safety of local use of lidocaine under neuromonitoring conditions has not been studied. Despite recommendations to avoid the local use of lidocaine for tracheal intubation, there is evidence of the safety of this technique in the absence of a negative impact on the quality of neuromonitoring.

The purpose of this study is to test the hypothesis that the quality of recovery with topical lidocaine is better than placebo. At the same time, the investigators assume that recovery after surgery will be comparable with both local and intravenous use. Intergroup differences in arterial hypotension, depth of anesthesia and intraoperative neuromonitoring parameters will also be investigated.

What participants receive

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

  • Intravenous lidocaineDrug

    Lidocaine IV 1.5 mg / kg BMI will be administered during induction into anaesthesia followed by infusion at a dose of 1.5 mg / kg / h until the end of the surgery.

  • Intravenous placeboDrug

    During induction and maintenance of anaesthesia, 0.9% sodium chloride solution will be injected intravenously at a rate equivalent to lidocaine solution.

  • Intra-cuff lidocaineProcedure or surgery

    The lidocaine solution will be applied to the intubation tube and the cuff will be filled with an alkalinised lidocaine solution.

  • Intra-cuff placeboProcedure or surgery

    The intubation tube will be lubricated 0.9% sodium chloride, the tube cuff will be filled with 0.9% sodium chloride solution.

What is being measured

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

  1. Quality of recovery 40 questionnaire

    Minimum and maximum values: 40 and 200, where higher scores mean a better outcomes

    Measured: First postoperative day

Secondary outcomes (7)
  1. Hypotension incidence

    Incidence of arterial hypotension (SBP <60 mm Hg)

    Measured: Intraoperative

  2. Hypotension duration

    Cumulative duration of arterial hypotension (SBP <60 mm Hg) expressed in minutes

    Measured: Intraoperative

  3. Cough rate

    Frequency of laryngeal reflexes

    Measured: In the operating room and during awakening.

  4. Minimal bispectral index

    Minimal observed intraoperative bispectral index value. Values less than 40 mean a worse outcomes.

    Measured: During surgery

  5. Bispectral index less then 40

    Cumulative duration of bispectral index less than 40. Values less than 40 mean a worse outcomes.

    Measured: During surgery

  6. Amplitude

    Amplitude of electromyographic potential during neuromonitoring of recurrent nerve

    Measured: During surgery

  7. Latency

    Latency of electromyographic potential during neuromonitoring of recurrent nerve

    Measured: During surgery

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Intravenous lidocaine and Intra-cuff lidocaine in people with Thyroid Neoplasm and Parathyroid Neoplasms, run by Saint Petersburg State University, Russia at 1 site in Russia.

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 21 Mar 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 Russia. 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?

Quality of recovery 40 questionnaire (time frame: First postoperative day). 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 21 Mar 2024.
