Module 9 Part 2 Asymptomatic Bacteriuria Flashcards
When is screening and treatment of asymptomatic bacteriuria indicated?
It is only indicated during pregnancy or before pre-operative genitourinary (GU) procedures.
What are the first-line antibiotics for asymptomatic bacteriuria (except during pregnancy and pre-op GU procedures)?
Amoxicillin, Nitrofurantoin (or Macrobid), TMP/SMX, and Fosfomycin.
How long should pregnant women be treated for asymptomatic bacteriuria if a positive urine culture is confirmed?
A 3-7 day antibiotic course is recommended.
Why should macro-crystals be preferred over micro-crystalline nitrofurantoin?
Macro-crystals are better tolerated, and micro-crystalline nitrofurantoin is contraindicated in renal failure and at term pregnancy.
When should trimethoprim and TMP/SMX be avoided during pregnancy?
They should be avoided during the first trimester and the last six weeks of pregnancy due to potential risks.
What is the role of cephalexin in treating asymptomatic bacteriuria?
Cephalexin has a role in treating pregnant women.
Why should fluoroquinolones be generally avoided during pregnancy?
They should be avoided because safer alternatives are available, and they should only be used if the potential benefit justifies the risk to the fetus.
