About this study

Official title: Great Auricular Nerve Block for Children Undergoing Tympanomastoid Surgery: Does the Addition of Clonidine Increase the Duration of Postoperative Analgesia?

The investigators goal is to determine the efficacy and duration of analgesia with the addition of Clonidine, an alpha-2 agonist, to local anesthetic blockade using bupivacaine, of the great auricular nerve in children undergoing tympanomastoid surgery.

Read the detailed description

The surgical anesthesia during the operative procedure will be maintained using volatile anesthetics. No prophylactic dexamethasone or ondansetron would be provided to any patients in either group. Anesthesia will be discontinued at the end of the procedure and the patient will be extubated once standard extubation criteria have been met. Patients will be then taken to the postoperative recovery room where they will be evaluated for pain and discomfort by a blinded observer using the CHIPPS (Children and Infants Postoperative Pain Scale). If two consecutive pain scores at 5 minute intervals is >6, they will be rescued with incremental doses of 0.05 mg/kg of intravenous morphine required to reach a score of <6. The number of rescue doses as well as the pain scores will be documented. These patients will be also observed for the presence of nausea/vomiting. Any patient who vomits more than two times will be rescued with ondansetron 0.1 mg/kg intravenously. All patients will be continued to be evaluated in the 23 hour unit. Pain and side effects will be assessed for the next 6 hours or until discharge from the 23 hour observation facility. Standard doses of acetaminophen with codeine will be provided for pain relief in the 23 hour observational unit, as well as on discharge. The number of doses of acetaminophen with codeine will be recorded. Time to discharge from the hospital will also be noted. A questionnaire designed to address parent/patient satisfaction will be utilized and will allude to the need for rescue analgesia and the need for any other additional analgesics provided. The use of any additional rescue pain medication will be provided to the families at the time of discharge. A follow-up phone call will be made in 24 hours to note the information provided on the questionnaire.

What is being measured

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

  1. Average Observer-Rated Patient Pain Scores

    Patients will be observed with behaviors rated at regular time intervals using the CHIPPS (Children and Infants Postoperative Pain Scale) pain survey. The CHIPPS scale values range from a minimum of 0 (no pain, better outcome) to a maximum of 10 (worst pain, worse outcome).

    Measured: 60 minutes

Secondary outcomes (2)
  1. Number of Participants With Nausea/Vomiting

    Incidence of nausea/vomiting during 24 hour observation

    Measured: 24 hours

  2. Number of Participants Requiring Use of Rescue Analgesic Medication in the Initial 24 Hours Postoperatively

    Count of participants who will require use of rescue analgesic medication in the initial 24 hours postoperatively as recorded in the hospital or by parents at home following discharge.

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 0.25% Bupivacaine + Clonidine in people with Tympanomastoid Surgery and Cochlear Implant, run by Ann & Robert H Lurie Children's Hospital of Chicago at 1 site in United States.

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 7 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 4 Aug 2021. 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. 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?

Yes. Results are posted in the registry (first posted 7 Jul 2021). 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?

Average Observer-Rated Patient Pain Scores (time frame: 60 minutes). 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 NCT01638052, which also lists 2 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 4 Aug 2021.
