Lecture 12: LE Pain Readings Flashcards
Most severe presentations of DVT (2)
- Phlegmasia cerulea dolens (cyanotic)
- Phlegmasia alba dolens (Pale)
Alba = albino = white
If someone has a PE, whats the likelihood they might have clinical signs of a DVT?
50%
Well’s for DVT
- Active CA in past 6 months
- Paralysis/paresis of lower limb
- Bedridden > 3 d 2/2 surgery in past 12 weeks
- Localized tenderness along deep veins
- Entire leg swollen
- Unilateral calf swelling > 3 cm below tibial tuberosity
- Unilateral pitting edema
- Collateral superficial veins
- Prior hx
>= 3 = high risk
When is venous US slightly impaired in dx DVT?
- Pelvic DVT
- Isolated calf DVT
- Obese
Which physical exam sign is non-specific for DVT?
Homan’s sign
Calf squeeze
Management of DVT
- LWMH
- UFH
- Xa inhibitor
What DVT subtype requires immediate tx with neutral position?
Phlegmasia cerulea dolens
Also consider IR for thombectomy
Top RFs for PAD
- Smoking
- > 70 years old
MC arteries for arterial embolism
- Femoral
- Popliteal
What 4 arteries are most likely to lead to limb ischemia?
- Femoropopliteal
- Tibial
- Aortoiliac
- Brachiocephalic
6 Ps of acute arterial limb ischemia
- Pain (earliest)
- Pallor
- Poikilothermia (cold)
- Pulsenessness
- Paresthesias
- Paralysis
Define claudication
- Cramping pain/ache
- Brought on by exercise, relieved by rest
- Reproducible
- Reocccurs at consistent walking distances
MCC of arterial embolism
Underlying thromboembolic dz
What ABI ratio is extremely concerning for critical limb ischemia?
< 0.41
Gold standard for diagnosing arterial occlusion
Arteriogram
Identify anatomy & directs tx of the limb
First steps to managing acute arterial occlusion
- Fluids
- Pain meds
- Dependent positioning (idk, it just says improves perfusion pressure)
- EKG & consider echo
What rutherford criteria requires immediate tx for acute limb ischemia?
2b or higher (immediately threatened)
What rutherford criteria may suggest amputation as tx for acute limb ischemia?
3 (irreversible)
Preferred AC for acute limb ischemia
UFH 80U/kg bolus + UFH 18U/kg/hr
Discharge meds for chronic PAD without comorbidities and no immediate limb threat
- Baby asa
- Loading dose of 325mg before d/c
Rutherford criteria chart for acute limb ischemia
How do community acquired MRSA skin lesions present?
- Warm
- Red
- Tender
- Abscesses that spontaneously drain
