Great Auricular Nerve Block for Children Undergoing Tympanomastoid Surgery

Status Completed

Clinical Trial Summary

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.

Clinical Trial 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
