Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: aerosolized 2% lidocaine (20mg/ml)
Description: The aerosolized solution to be used is 2% lidocaine (20 mg/ml) at a dose of 1.5 mg/kg with a maximum volume of 3 ml or adjusted to a volume of 3 ml with addition of NS solution.The aerosolized solution will be administered with an Aerogen ultrasonic nebulizer, which is standard of care for administering aerosolized solutions in our pediatric intensive care unit (PICU).After each treatment a 3-minute interval will be allowed prior to ETS and there will be a 4-6 hour wash out period between each treatment.
