Brief Summary:
Lidocaine is widely available and is a very commonly used local anesthetic. When administered intravenously, lidocaine infusions have anti-inflammatory effects and have significantly decreased the reliance on opioid use for adequate pain management in adult abdominal and spine surgeries. A major advantage of lidocaine infusion is that it is not associated with a significant side effect profile.The role of lidocaine in pediatric acute perioperative pain remains limited.

Condition or disease Intervention/treatment Phase
Children, Only Tonsillar Hypertrophy Adenoid Hypertrophy Drug: Lidocaine Iv Drug: Saline Solution Phase 4

Detailed Description:
The aim of the study is to determine if using lidocaine continuously during anesthesia care will decrease post-operative pain for children having their tonsils and adenoids removed.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 70 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

Enrolled patients will be randomly assigned into one of two intervention groups:

Group 1: systemic lidocaine infusion Group 2: normal saline infusion

Masking: Triple (Participant, Care Provider, Outcomes Assessor)
Masking Description: Anesthesia care providers will be acquiring the study solution from the institution's pharmacy (lidocaine or saline) to administer perioperatively. The pharmacy will prepare the study solutions per randomization and label the solution as the study solution without reference to lidocaine or saline. Per protocol, the care providers will then administer the study solution as a weight based infusion.
Primary Purpose: Treatment

Actual Study Start Date : May 7, 2019
Estimated Primary Completion Date : July 2021
Estimated Study Completion Date : September 2021

Primary Outcome Measures :
  1. Change in Pain Scores [ Time Frame: 15 minute intervals in postanesthesia care unit; up to 120 minutes following surgery. ]
    FLACC scale includes 5 categories (Face, Legs, Activity, Cry, Consolability) of pain behaviors scored from 0-2 to provide a total pain score ranging from 0 to 10 with higher numbers indicating greater or worse pain.

Secondary Outcome Measures :
  1. Opioid consumption [ Time Frame: Total perioperative period: time in the operating room until time of discharge to home from the postoperative anesthesia care unit (PACU) ]
    Morphine equivalents

  2. Emergence delirium scores [ Time Frame: 5 minute intervals for the first 30 minutes in postanesthesia care unit, then every 15 minutes for an additional 90 minutes after surgery ]
    Pediatric Anesthesia Emergence Delirium (PAED) scale to differentiate emergence delirium from postoperative pain. The scale includes 5 categories (eye contact, purposefulness of actions, awareness of surroundings, restlessness, inconsolable) each scored from 0 to 4 to provide a total score ranging from 0 to 20 with higher numbers being worse indicating that the emergence behaviors correlate better with emergence delirium.

  3. Parental satisfaction with the anesthetic [ Time Frame: Evaluated once on postoperative day 1 (or 24 hours after surgery) ]
    Measured on a scale from 0 to 10, where 0 means very unsatisfied and 10 means very satisfied; higher numbers are better
