PPP EOR Topics Flashcards
Most common presentation of PAD
Intermittent claudication
Leriche’s syndrome
Thigh or buttock claudicayiob, impotence, decreased femoral pulses
Livedo reticularis
Mottling of skin
Bruits in a peripheral vessel indicate occlusion is this bad
50% occlusion
ABIs with PAD
Normal 1-1.2
PAD <0.90
Severe PAD < 0.50
Rest pain/limb ischemia <0.4
*ABI of at least 0.85 needed to heal ulcers in diabetics
Thx of intermittent claudication
Cilostazol
Where do most AAAs occur?
Infrarenally
At what size is AAA rupture more likely?
> 5cm
Which bp med should a pt with an AAA be on to prevent aneurysm growth?
BB
When is immediate surgical intervention indicated for an AAA?
> 5.5cm or >0.5cm expansion in 6 months
Describe monitoring/referral guidelines for AAAs <5.0cm
3-4cm US annually
4-4.5cm US every 6 months
>4.5cm vascular surgery referral
Where do most aortic dissections occur?
65% in ascending
Most important predisposing factor for aortic dissection (present in 80% pts)
Hypertension
Sudden onset of severe tearing ripping knife-like chest pain
Aortic dissection
DeBakey classification of aortic dissection
Type I originate in ascending and propagates distally
Type II isolated to ascending
Type III originates in descending and propagates proximally
Stanford aortic dissection classification
A - involves ascending aorta and/or aortic arch
B - isolated descending aorta
Trousseau syndrome
Migratory thrombophlebitis associated with malignancy
Tx of superficial thrombophlebitis
Supportive with extremity elevation, warm compressed, NSAIDs and elastic supportive compression stockings
Asymmetric calf swelling >3cm should make you think of this
DVT
Cerulea alba
Milky white pallor with occlusion of deep venous system
Cerulea dolens
Cyanosis and swelling of limb with sudden pain associated with superficial and deep venous system compression
Antidote for heparin toxicity
Protamine sulfate
If someone has a VTE what is the minimum time frame to treat with anticoagulants?
3 months
Compare and contrast skin changes in peripheral venous v. Arterial dz
Venous-stasis dermatitis, brownish pigmentation, edema
Arterial- atrophic changes such as thin shiny skin, loss of hair thick nails, pallor, dry skin, livedo reticularis(mottled appearance)
Cheyne-Stokes
Smooth increases in respiration’s followed by gradual decrease and apnea
Caused by hypercapnia
Biot’s breathing
Quick shallow breaths of equal depth followed by a period of apnea
Seen with brain stem damage and opioid use
Kussmaul’s respirations
Deep rapid continuous respirations
Associated with metabolic acidosis
Vomiting/NG SUCTION, chronic diarrhea, and loop diuretics cause this kind of acid base imbalance
Metabolic alkalosis
Normal blood pH
7.35-7.45
> 7.45 alkalosis
<7.35 acidosis
Normal Pco2
35-45
Normal HCO3
22-26
Parietal cells secrete ________ and are stimulated by ______, _______, and ________.
HCl
Gastrin
Histamine
Ach/vagus nerve
Most common cause of noncardiac chest pain
GERD
