Q

When you start working, expect to get such calls from the micro lab staff :

  • “Hello dr, we have isolated gram positive cocci in clusters, in Tan See See’s
    blood culture.”
  • “Hello dr, you have asked for urgent gram stain on Ng Ann Bee’s CSF, we could see gram positive cocci in pairs”
  • “Hello dr, we have isolated gram negative bacilli in A Gaganathan’s blood culture taken from the central line”
  • “Hello dr, you have asked for urgent gram stain on Ali Bin Hasan’s knee aspirate, we could see gram positive cocci in chains”

a. How does this information help you?
b. Does this gram stain info influence which antibiotic you would prescribe?

A

a. sterile sites have microbes. BAD, will spread
b. Check best guess/empirical AB used

Q

EXAM: Broadest to narrowest AB spectrum

A
  • Broadest: carbapenem (big dad): ALL gram + and gram - except CRE (Carbapenem-Resistant Enterobacterales)
  • Tazocin: unresolved even with S to extended spectrum beta lactamase (ESBL) and Amp C, CRE resistant to it
  • Augmentin and ceftriaxone (narrow): All + ok, -ve CRE, ESBL, Amp C, pseudomonas aeruginosa resistant to it
