Nebulized Lidocaine

KEY POINTS:
--not a ton of evidence for use, but sounds cool, probably safe (in the appropriate non-toxic dose)
--reminder: max dose of lidocaine (without epinephrine) = 4.5mg/kg

ASTHMA/COPD:
--some benefit in daily long-term therapy for asthma, but doesn't apply to us in the ED
--lidocaine can cause bronchospasm in asthmatics, so one study pretreated with albuterol
--one study's sample dose: 1ml of 1% lido in 4 ml NS
--may be useful for cough suppression

NG TUBE PLACEMENT (in kids):
--apparently, not much proof that it helps or makes it less painful

Reference(s): asthma long-term, cough suppression, more cough suppression, ng tube, more ng tube
