Term
most all ABx (except vanco) should be given at what interval prior to cut time
Definition
30-60 minutes
Term
the most common in vitro predictor of antimicrobial effect
Definition
minimum inhibitory concentration (MIC)
Term
inhibiting bacterial growth without killing the organism
Definition
bacteriostatic
Term
killing or rendering bacteria dysfunctional
Definition
bactericidal
Term
drug that accounts for most fatal anaphylactic drug reactions
Definition
penicillin
Term
structure that is shared by penicillin, cephalosporins, carbapenems and monbactims. it is this structure that drives the allergy to the drug.
Definition
beta lactam ring
Term
enzyme produced by bacteria (usually mutated) that breaks down ABx
Definition
beta lactamase
Term
class of ABx that can kill a variety of bacteria that are both gram + and gram -
Definition
broad spectrum (GL's spelling: BRAOD SPECTRIM)
Term
1st generation cephalosporin, very common ABx for surgery (excellent for skin infections).
Definition
Cefazolin
Term
Cefazolin: adult dosing, time needed for IVP, when to rebolus
Definition
adult: 1 gram
give IVP 3-5minutes
rebolus if case is longer than 3hrs (still open and not on skin)
Term
2nd generation cephalosporins (2). good gram - coverage, commonly used in appys and other bowel surgeries
Definition
cefoxitin & cefotetan
Term
Cefoxitin: adult dosing, time needed for IVP, when to rebolus
Definition
1-2 grams
IVP over 3-5min
rebolus at 2hrs
Term
Cefotetan: adult dosing, time needed for IVP, when to rebolus
Definition
1-2 grams
IVP over 3-5min
rebolus at 4 hrs
Term
glycopeptide used against gram + organisms. drug most commonly used for MRSA.
Definition
vancomycin
Term
T/F: Vanco is a substitute for pts with cephalosporin allergy
Definition
true
Term
Vancomycin: adult dosing, time needed for IVP, when to rebolus
Definition
1 gram
administer over 60 MIN!!! (admin within 120minutes of cut time)
redose at 12hrs
Term
most common adverse effect of vanco (bonus: what can this condition progress to if drug given too fast?)
Definition
red man syndrome (due to large histamine release)
bonus: tachycardia and hypotension
benadryl can be given to help alleviate symptoms
Term
category of drug that irreversibly inhibits protein synthesis and is used against gram - organisms. almost completely secreted thru kidney.
Definition
aminoglycosides (ex: Gentamicin, neomycin, tobramycin)

30-60min (Can be given IV or IM)
Term
2 severe side effects of aminoglycosides
Definition
Nephrotoxicity and Ototoxicity
Term
T/F: aminoglycosides prolong NMDR activity (if true, by what mechanism do they prolong NMDR; and how is it treated)
Definition
true
inhibition of pre-junctional ACh release and reduction of post-synaptic sensitivity to ACh.
effect can be reversed with neostigmine and calcium improves muscle strength.
Term
pro-drug (meaning something has to cleave a portion off before drug becomes active) that kills anaerobic bacteria, protozoal and parasites

Term
metronidazole/flagyl: adult dosing, when to rebolus

Term
mechanism by which clindamycin prolongs effects of NMDRs
Definition
blocks release of ACh at the NMJ
Term
Clindamycin: adult dosing, time needed for IVP, when to rebolus

DM
corticosteroid therapy
immunocompromised
Term
