High Yield Flashcards
Fibrin
Links Gp2b/3a to form PLT plug
Thrombin functions
- Fibrinogen to fibrin
- Activates f5, 8
- Activates PLTS
AT3 Functions
- Inhibits thrombin
2. Inhibits f9, 10, 11
Plasmin
Degrades f5, 8, fibrinogen, and fibrin
TXA2
Released from PLT
Ca release exposes Gp2b/3a
Increases PLT aggregation and promotes constriction
Cryo
vWF, f8, fibrinogen
FFP
All factors, Protein C and S, AT3
DDAVP
Cause endothelium to release f8 and vWF
Clopidogrel
MOA: ADP receptor (gp2b/3a) antagonist
Aminocaproic acid
Plasmin inhibitor
Use: DIC, excess tpa
Warfarin reversal
- Emergent: PCC or f7a (more s/e)

Cimetidine Isoniazid Ketoconazole Erythromycin Cipro Flagyl Allopurinol Verapamil Amiodarons MAOi Disulfuram
Halothane
Slow onset/offset. Least pungent (children)
s/e:
- highest cards depression and arrhythmia
- halothane hepatitis
- avoid w/ neurosurg
Sevoflurane
fast, less laryngospasm, less pungent
good for mask induction
Isoflurane
Good for neurosurgery
Pungent (not used for induction)
Propofol
Rapid distribution and on/off
s/e- hypotension, resp depression, meta acid
metabolism- liver
Ketamine
No respiratory depression
s/e
- hallucination, catelcholamine release, airway secretions, increased CBF
- c/i in head injury
Etomidate
Fewer hemodynamic changes Fast acting Fewest cards s/e s/e - adrenocortical suppresion w/ cont infusion
Dexmedetomidine
Mech- CNS alpha2 ago Not an induction agent. Good for intubated pts Anesthesia and analgesia s/e - not for more than 24h
Depolarizing agents
Succinyl choice
Malignant hyperthermia
Hyperkalemia
Glaucoma
Ca EKG
HyperCA- Short ST, wide T
HypoCA- long QT
HypoMg EKG
Tall t waves
Depressed ST
K ECG
HyperK- Peaked T, wide QRS, long PR
HypoK - ST depression, inverted T
