Flashcards in Clinical Antibiotic Use Deck (17):
1

What utility is associated w/ specimen collection? Pitfalls?

a

2

What are some important points to keep in mind when obtaining appropriate specimens?

- Infecting orgs should be obtains BEFORE the start of therapy
- Tissues/fluids needs for cultures --- NOT swabs
- Deeper specimens preferred over superficial
- Don't culture fluid from a drain UNLESS it was just freshly placed
- Remember it's volume dependent! plus bacteria doesn't live long on swabs
- The gram stain is your friend (you will first know if a org is G(+) or G(-) and its shape before the actual org)

3

Describe the principles involved during empiric antibiotic use

THINK:

1) What is the infectious syndrome? Where is it located?
2) What are common pathogens that may cause this syndrome?
3) What is the likely resistance associated with the organisms being considered?
4) What's the most appropriate antibiotic to use?
