HEME Flashcards
Factor common pathway and one drug acts here
factor 10
heparin anti-factor Xa
trigger of the extrinsic pathway
tissue thromboplastin outside of the vessel
trigger of the intrinsic pathway
collagen exposure
diseases of the intrinsic pathway
hemophilia A. and B.
how is factor XIII related to clot
measured by area clot stability
primary factor that pro time measures
factor VII
how dose deficiency in protein C and S. present
blood clots at young age
Minor risk factors create DVT
thrombus more commonly than factor V Leiden deficiency
workup for patient with multiple abortions
anticardiolipin antibody
findings with anticardiolipin antibody
only procoagulants screening test
multiple portions
Increase in PTT and procoagulant screening test positive the
major test positive with hemophilia A. and B.
PTT
percentage of hemophilia factor and needed for major Versus minor surgery
Cardiovascular, prostate, neurosurgery:
Greater than 100% x3 days
80%-100% x4-7 days
Greater than 50% for 8-14 days
Marjor:
80-100%
for 3 days then greater than 50% for next 7-11 days
minor:
greater than 50% for 3-7 days
description and interpretation of mixing study correction studies her lupus
normal serum added to patient
does not correct: Negative
does not correct is good
Corrects with normal plasma: Positive
most common hypocoagulable condition
von Willebrand’s disease
bleeding time up
( possible increase in PTT)
mechanism of von Willebrand disease
prevent factor VIII from activation
von Willebrand’s disease the does not correct with DDAVP
von Willebrand 3
missing factor endothelium
treatment of von Willebrand disease
cryoprecipitate
DDAVP
preop treatment of uremia
dialysis
DDAVP during surgery
treatment to reverse Coumadin right away and efficacy
FFP
six-hour efficacy
major mechanism of heparin
acts on thrombin
factor 10
heparin is toanti-factor Xa
what lab values his warfarin effect
PT elevated
possible effect also on PTT
Ribaroxaban
Xarelto
irreversible heparin-like mechanism
Dabigatran
Pradaxa
warfarin-like mechanism
Hyper homocystinemia Defined, severity, treatment
20 times more blood clots and any other hypercoagulable disease
Most dangerous
Treatment:
folic acid
B12
differential diagnosis with arterial thrombus and findings
hyper homocystinemia
HIT - have been induced thrombocytopenia
white clot-represent clumped platelets
prothrombin factor
II
thrombin factor
IIa
potential coagulopathy from prostate surgery
DIC
treatment DIC
Amicar
Aminocaproics acid
HIT time course
5-7 days from first exposure
mins - hrs from second exposure
Argatrobam mech
Leach
Shorter half-life
Liver cleared
blood product with highest infection rate
platelets
highest infection contaminant
How much does 6 pack race platelet count
sixpack 50,000
storage time of packed cells
the 42 days
increase hematocrit with one unit
3%
hematocrit with a hemoglobin of 7
