Buffered lidocaine expiration dating
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.Lidocaine is a common local anesthetic frequently nebulized during bronchoscopy procedures, allowing the bronchoscope to reach greater depths in the airways.
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.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.
