Q

Atypical CAP organisms, definition, treatment?

A

Lack cell was so do not respond to beta lactams

Mycoplasma pneumonia - erythromycin (macrolide, inhibit protein synthesis)/clari (macrolide, inhibit protein synthesis) + dox (tetracycline - inhibits protein synthesis)
Staphylococcus aureus - amoxicillin + dox/clari + fluclox (penicillinase resistant penicillin - prevents peptidoglycan cell wall cross linking)
Legionella
Clamydia

Q

Ventilator associated pneumonia? Prevention? Treatment

A 
Pseudomonas aeurginosa, staph aureus 
prevent by mouthwash, silver coated tube, wean off ASAP
Ciprofloxacin PO (quinolone - inhibits DNA gyrase - inhibits DNA synthesis) 
Gentamicin IV (aminoglycoside - inhibits bacterial protein synthesis)
