Transition DVT Flashcards
Virchow’s Triad
- Hypercoagulability
- Venous stasis
- Tissue damage
6 risk factors for DVT
- Venous stasis:
lengthy surg
immob
older age
preggo
afib aflutt
HF
obesity
stroke
denervated limb
orthopedic surg - Venous endothelial injury
prev dvt
iv cath
bone fracture
chemical injury (smoking)
high CBG chronic
trauma
vericose
HTN
pacing wires
Central lines
dialysis cath
chemotherapy - hypercoagulability
tumor
cancer
dehydration
oral contraception
estrogen
sepsis
blood dyscratias
burns
genetic predisp
preggo
Deep veins are thin or thick walled
thin
Venous system is high pressure or low pressure?
low = clots
LJ’s risk factors
smoking
decreased mobility
A fib and flutter
previous DVT
70 years old
bus driver (sedentation)
Most important assessments for LJ
- Cardiovascular
baseline vitals
heart sounds
compare extremities - Vascular
venous assessment
warmth
redness
pain
edema
distal pulses
cap refil
baseline calf and thigh girth
Homan’s sign (not fool proof) - Respiratory system
breath sounds
dyspnea
chest pain
baseline pulmonary ass - Neuro exam
LOC
CNFS
restlessness
lethargy
AOX?
Most serious side effect of DVT
PE AND CVA
8 assessments to monitor (PE syptoms)
- crackles
- cough
- tachycardia
- restless
- dyspnea/tachypnea
- pleuritic chest pain
- fear/apprehension
- hemoptysis
- fever
- N/V
- Cyanosis
NEED BASELINE ASSESSMENT to be able to recognize right away

Why Lovenox instead of Coumadin?
Coumadin onset 12-24 hours, peak 1-2 days
Needs rapid:
Enoxaparin (3-5 hours peak)
Enoxaparin dosage
1 mg per kilogram
Special techniques for subQ Enoxaparin
rotate sites
love handles (lovenox)
DON’T expel air bubble
DON’T aspirate
DON’T massage
T/F lovenox monitored by aPTT
False: anti Xa
Bed rest?
Nah
But if can’t move:
change pos freq
dorsiflex/plantar flex
foot pumps
ankle circles
knee to chest
don’t cross legs
don’t massage area
right leg elevated, NO pressure under knee
no sudden muscle movements
SCD on unaffected leg
Ted hose unaffected leg
What labs to order
PLT (HIT)
CBC
chest xray
d-dimer
ct scan chest
ABGs
Occult blood
