About this study

Official title: Bupivacaine Versus Lidocaine Infiltration for Postoperative Pain in Thyroid Surgery: A Randomized Controlled Trial

The purpose of this study is to compare the efficacy of Bupivicaine and Lidocaine for postoperative pain control in thyroid surgery.

Read the detailed description

Patients planned for total thyroidectomy will be recruited for participation. After being informed about the study and potential risks, all patients giving written informed consent will be screened for eligibility for study entry. Patients that meet inclusion and exclusion criteria will be randomized via block randomization in a double blind fashion and a 1:1 ratio to surgical incision infiltration with Bupivacaine (0.5% with 1:200 000 epinephrine) or Lidocaine (2% with 1:100 000 epinephrine).

Being tested
Bupivacaine 0.5% with 1:200 000 epinephrine, Lidocaine 2% with 1:100 000 epinephrine
Keywords

What is being measured

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

  1. Postoperative Pain

    Patient reported postoperative pain reported on a 10cm pain visual analogue scale (VAS), minimum value of 0cm (no pain) and maximum value of 10cm (worst pain possible), lower VAS measurement represents better outcome

    Measured: 30 minutes after surgery

    Measured: 1 hour after surgery

  3. Postoperative Pain

    Patient reported postoperative pain reported on a 10cm pain visual analogue scale (VAS), minimum value of 0cm (no pain) and maximum value of 10cm (worst pain possible), lower VAS measurement represents better outcome

    Measured: 2 hours after surgery

  4. Postoperative Pain

    Patient reported postoperative pain reported on a 10cm pain visual analogue scale (VAS), minimum value of 0cm (no pain) and maximum value of 10cm (worst pain possible), lower VAS measurement represents better outcome

    Measured: 3 hours after surgery

  5. Postoperative Pain

    Patient reported postoperative pain reported on a 10cm pain visual analogue scale (VAS), minimum value of 0cm (no pain) and maximum value of 10cm (worst pain possible), lower VAS measurement represents better outcome

    Measured: 4 hours after surgery

  6. Postoperative Pain

    Patient reported postoperative pain reported on a 10cm pain visual analogue scale (VAS), minimum value of 0cm (no pain) and maximum value of 10cm (worst pain possible), lower VAS measurement represents better outcome

    Measured: 8 hours after surgery

  7. Postoperative Pain

    Patient reported postoperative pain reported on a 10cm pain visual analogue scale (VAS), minimum value of 0cm (no pain) and maximum value of 10cm (worst pain possible), lower VAS measurement represents better outcome

    Measured: 12 hours after surgery

Secondary outcomes (9)
  1. First dose of additional postoperative analgesia

    Time since completion of surgery when additional postoperative analgesia outside of standardized protocol was administered

    Measured: Up to 72 hours after surgery

  2. Inpatient analgesia utilization

    Quantity of standardized analgesia used during admission

    Measured: Up to 72 hours after surgery

  3. Outpatient analgesia utilization

    Quantity of standardized analgesia used between discharge and 4 week outpatient follow up

    Measured: Up to 4 weeks after surgery

  4. Time to return of sensation

    Patient reported time to return of sensation at surgical site

    Measured: Up to 4 weeks after surgery

  5. Incidence of postoperative complications

    Incidence of complications including bleeding, hematoma, surgical site infection, dehiscence, re-exploration, persistent paresthesia

    Measured: 4 weeks

  6. Incidence of local anesthesia related adverse events

    Incidence of adverse events including CNS (tinnitus, blurred vision, dizziness, tongue paresthesias, circumoral numbness, seizures, CNS depression) and cardiovascular (hear block, sinus bradycardia, sinus arrest, ventricular arrhythmias) events.

    Measured: 4 weeks

  7. Postoperative pain

    Patient reported postoperative pain reported on a 10cm pain visual analogue scale (VAS), minimum value of 0cm (no pain) and maximum value of 10cm (worst pain possible), lower VAS measurement represents better outcome

    Measured: 1 week

  8. Postoperative pain

    Patient reported postoperative pain reported on a 10cm pain visual analogue scale (VAS), minimum value of 0cm (no pain) and maximum value of 10cm (worst pain possible), lower VAS measurement represents better outcome

    Measured: 2 week

  9. Postoperative pain

    Patient reported postoperative pain reported on a 10cm pain visual analogue scale (VAS), minimum value of 0cm (no pain) and maximum value of 10cm (worst pain possible), lower VAS measurement represents better outcome

    Measured: 4 week

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Bupivacaine 0.5% with 1:200 000 epinephrine and Lidocaine 2% with 1:100 000 epinephrine in people with Postoperative Pain and Thyroid Diseases, run by St. Joseph's Healthcare Hamilton at 1 site in Canada.

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 14 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 28 Nov 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 Canada. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Contact Michael Xie, MD ((905) 522-1155 ext. 4765, michael.xie@medportal.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Postoperative Pain (time frame: 30 minutes after surgery). The study lists 7 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 28 Nov 2023.
