About this study

Official title: Pediatric Tonsillectomy Pain Reduction Study, a Randomized, Placebo Controlled, Double-Blind Clinical Trial Using Clonidine and Local Anesthetics

Tonsillectomy is associated with a significant decrease quality of life in children secondary to pain, which is worsened with swallowing. The objective of the current study is to conduct a prospective, double-blind, placebo-controlled, randomized clinical trial using a pre-tonsillectomy infiltration of the tonsillar fossa comparing three treatment regimens in reducing post-tonsillectomy morbidity (i.e. pain, poor oral intake): 1) Placebo (saline injection) 2) bupivacaine (0.5%) + lidocaine (1%), 3) bupivacaine (0.5%) + lidocaine (1%) + clonidine (25 µg).

Read the detailed description

Tonsillectomy is associated with a significant decrease quality of life in children secondary to pain, which is worsened with swallowing. Previous studies in the pediatric population have demonstrated a significant decrease in post-operative pain/morbidity when administering pain reduction medications into the tonsillar fossa prior to removal. While these studies have shown great promise, no large randomized trial of the most promising medications has been conducted. Because of this, many otolaryngologists do not administer intra-operative medications aimed at reducing post-operative pain. The objective of the current study is to conduct a prospective, double-blind, placebo-controlled, randomized clinical trial using a pre-tonsillectomy infiltration of the tonsillar fossa comparing three treatment regimens in reducing post-tonsillectomy morbidity (i.e. pain, poor oral intake): 1) Placebo (saline injection) 2) bupivacaine (0.5%) + lidocaine (1%), 3) bupivacaine (0.5%) + lidocaine (1%) + clonidine (25 µg).

What is being measured

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

  1. Total Number of Post-operative Doses of Analgesics.

    The total number of intravenous fentanyl doses given PACU which will be compared between the three randomized groups (arms)

    Measured: Post-operative thru day 7

Secondary outcomes (6)
  1. Median Number of Pain Medication Doses

    The median number of intravenous fentanyl doses administered in the PACU due to pain

    Measured: in recovery room

  2. Total Time Until Discharge From Hospital.

    Measured: Day of Surgery

  3. Mean Visual Analog Scale Pain Number.

    Visual analog pain scale range is 0-10 with 0=no pain and 10 = worst pain ever

    Measured: in recovery room; post-operative days 1,3,5 & 7

  4. Number and Percent of Participants Able to Tolerate Only Liquids

    The number and percent of patients whose post-operative diet has advanced to liquids only on post-op days 1, 3, 5 \& 7

    Measured: post-operative days 1,3,5 & 7.

  5. Number and Percent of Participants Able to Tolerate Only a Soft Diet

    The number and percent of patients whose post-operative diet has only advanced to a soft diet on post-operative days 1, 3, 5 \& 7

    Measured: post-operative days 1,3,5 & 7.

  6. Number and Percent of Participants Able to Tolerate a Regular Diet

    The number and percent of patients whose post-operative diet has to a regular diet on post-operative days 1, 3, 5 \& 7

    Measured: post-operative days 1,3,5 & 7.

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 4 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 2 Jul 2017. 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 United States. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Jul 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Total Number of Post-operative Doses of Analgesics. (time frame: Post-operative thru day 7). 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 NCT00678379, which also lists 7 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 2 Jul 2017.
