Abstract
|
|
|
Background: We performed this stody to find out about antimicrobial effect of lidocaine which is commonly used local anesthetic, and thrombin and epinephrine used for hemostasis during bronchoscopic procedures.
Materials & Methods: The microorganisms that were cultured from specimens obtained during bronchoscopy were Staphylococcus aureus (n=42), Streptococcus pneumoniae (n=42), Klebsiella pneumoniae (n=42), and Pseudomonas aeruginosa (n=43) collected from St. Mary’s Hospital, from March to Sep 2004 were used for susceptibity testing. Susceptibility to lidocaine, thrombin, and epinephrine were tested according to the National Committee for Clinical Laboratory Standards.
Results: MIC50 and MIC90 of lidocaine for S. aureus, S. pneumoniae, P. aeruginosa were all 20,000 microgram/mL and that for K. pneumoniae were 10,000 microgram/mL. MIC50 and MIC90 of thrombin for both S. aureus and P. aeruginosa was 500 IU/mL and above 500 IU/mL, respectively; that for K. pneumoniae were all above 500 IU/mL and for S. pneumoniae they were 125 IU/mL, MIC50 and MIC90 of epinephrine for K. pneumoniae and S. pneumoniae were above 500 microgram/mL; that for S. aureus and P. aeruginosa were 500 microgram/mL.
Conclusion: We observed possible antimicrobial effect of lidocaine, thrombin, and epinephrine in vitro against pathogens such as S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa, which are common respiratory microorganisms. The use of these agants could affect the result of bacterial culture.
