Q

Dynamic insufficiency

A

most common
occurs when there is excess lymph circulating that exceeds the transport capacity
pitting edema
Examples: venous insufficiency, CHF, pregnancy

Q

Those at greater risk should

A

avoid injury to skin
avoid constriction of extremity
diet and exercise to maintain healthy weight
when exercising, observe any changes in limb
avoid extreme hot and cold
wear compressions during strenuous activity and when standing or sitting for long periods of time

20
Q

Procedure for limb circumference measuring

A

7 circumferences recommended for upper and lower extremities to see if fluid has been removed and not just redistributed

21
Q

A difference of ___-___cm between 4 comparative circumferences on bilateral UE is evidence of lymphedema.

22
Q

Mild lymphedema is classified as

A

<3 cm between affected and unaffected limbs

23
Q

Moderate lymphedema is classified as

24
Q

Sever lymphedema is classified as

25
Staging of Lymphedema: 0
latent or preclinical stage no visible edema transport capacity is affected
26
Staging of Lymphedema: 1
reversible pitting edema present and increases with activity or heat but diminishes with elevation and rest.
27
Staging of Lymphedema: 2
spontaneously irreversible non-pitting edema and does not change with elevation or rest skin begins to show fibrotic changes stemmers sign is positive
28
Staging of Lymphedema: 3
elephantiasis stage extensive non-pitting edema significant fibrotic changes papillomas skinfolds kyperkeratosis infection is common
29
Treat lymphedema with
complete decongestive therapy
30
CDT two phases:
Phase I is acute treatment in outpatient 4-6 weeks Phase II is self-management Can return to phase I when significant changes are noted.
31
CDT consists of
manual lymphatic drainage compression therapy exercise skin care
32
Compression therapy is in phase ___. ___-____bandages are used because they have a ____ resting pressure. Phase II consists a ___ of compression during the day and night. Bandages and garment should have ____ pressure distally.
I short stretch low combination higher
33
Basic guidelines for exercise should start with
trunk exercises followed by extremity working from proximal to distal end with trunk again and deep breathing wear compression during exercise
34
Soaps and moisturizers in lymphedema
low or neutral pH
35
Contraindications to CDT
acute infection cardiac edema diabetes HTN malignancy renal insufficiency DVT
36
Filariasis
parasitic infection most often seen in tropical climates most common causes of secondary lymphedema
37
hyperkertosis
thickening of outermost layer of skin observed in stage 3 lymphedema
38
Lymphadenitis
inflammation and infection of lymph nodes
39
Lymphadenomegaly
enlargement of lymph nodes secondary to cancer, infection, allergic reactions
40
Lymphadenopathy
affects size, number or consistency of lymph nodes
41
Lymphangitis
infection and inflammation of lymphatic sys
42
Milroy's disease
inherited type of primary lymphedema that typically presents in infancy. BLE
43
Papilloma
benign wart in stage 3
44
Spleen
upper left quadrant responsible for filtration of RBCs as well as production of antibodies to fight infection
45
Stemmers sign
positive if dorsal base of second toe/finger cant be easily lifted away from bone which indicates thickening of skin due to fibrotic changes
46
Thymus
posterior to sternum and anterior to heart that produces T cells and T lymphocytes to help combat infection
