Buffered lidocaine expiration dating
route if the only goal of lidocaine treatment is to manage bronchial hyperactivity.If lidocaine is being used as a local anesthetic, they recommended the nebulized route.One patient receiving inhalation therapy complained of lightheadedness and vertigo.Roughly one third of the patients mentioned minor central nervous system effects.conducted a placebo-controlled, double-blind, randomized study that examined inhaled lidocaine's ability to attenuate bronchoconstriction compared with i.v. They tested the preventive properties of lidocaine against histamine-induced bronchoconstriction in 15 young, healthy patients showing bronchial hyperactivity.
Supplemental lidocaine and total midazolam doses required during the procedure and patient and bronchoscopist perceptions of cough and discomfort were compared. Comments on Medscape are moderated and should be professional in tone and on topic.The inhaled lidocaine doubled the histamine threshold of the patients, a mean ± S. concentration of up to 14.8 ± 3.5 mg/m L, suggesting that patients could tolerate more bronchial stimulation (p = 0.0007).Peak serum lidocaine concentrations were significantly lower (p = 0.0229) in patients receiving inhalation therapy when compared with i.v. Heart rate and blood pressure were not significantly affected.Research investigating the use of nebulized lidocaine is limited and early results are contradictory. You must declare any conflicts of interest related to your comments and responses.Because lidocaine toxicity is a concern, it is important for caregivers to carefully weigh the risk and benefit for each patient.

The study found no differences among the anesthetics used before lidocaine inhalation.
