A

Fluid is transported from lymphatic
capillaries

Lymphatic collecting vessels

Along the length of these vessels, lymph
nodes occur to filter the lymph

Lymphatic trunks

Lymphatic collecting ducts

Q

what is Pitting edema:

A

Pressure on the edematous tissues with the fingertips causes an
indentation of the skin that persists for several seconds after the pressure is removed.

This reflects significant but short duration edema with little or no fibrotic changes in
skin or subcutaneous tissue.

Q

what is weeping edema

A

This represents the most severe and long duration form of
lymphedema.

Fluids leaks from cuts or sores; wound healing is significantly impaired.

Lymphedema of this severity occurs almost exclusively in the lower extremities.

Q

what is Stemmer Sign

A

physical exam that helps diagnose lymphedema, a condition that causes the skin to thicken and become fibrotic.

The test involves gently pinching the skin at the base of the toes or fingers to see if it can be lifted

pinched (lifted) or is difficult to pinch compared with the uninvolved
limb

25
stage 0 - lymph
* No clinical edema, occasional reports of heaviness * Stemmer sign negative * Tissue and skin appears normal
26
stage 1 - lymph
Edema present (soft and pitting) Edema increases with standing and activity but reduces on elevation Stemmer sign negative
27
stage 2 - lymph
Hard swelling present; progresses to non-pitting ”brawny” edema * Stemmer sign positive (although still may be negative at early stage II) * Tissue appears fibrosclerotic; proliferation of adipose tissue
28
stage 3 - lymph
* Edema present; severe ”brawny” nonpitting edema * Stemmer sign positive * Skin changes (papillomas, deep skinfold, warty protrusions, hyperkeratosis, mycotic infections, etc.) * Repeated bacterial and viral infections are common
29
1+ - pitting edema
Mild, barely perceptible indentation; <1/4-inch pitting
30
2+ - pitting edema
Moderate, easily identified depression; return to normal within 15 seconds; 1/4-to-1/2-inch pitting
31
3+ - pitting edema
Severe, depression takes 15 to 30 seconds to rebound; 1/2-to-1-inch pitting
32
4+ - - pitting edema
Very Severe, depression lasts for >30 seconds or more; >1 inch pitting
33
what areas does Lipedema effect
bilateral condition affecting the lower extremities affects the proximal areas, such as the buttocks and thighs, but not distal areas, such as the feet
34
what is lipedema
an abnormal build-up of fat in your legs and sometimes arm
35
what does lipedema effect
affects skin’s elasticity, the skin sensitive to pressure and touch, which makes it bruise easily and painful
36
Lymphedema vs Lipedema - distribution
lymph - Unilateral or bilateral with one leg affected more severely (asymmetric) lip - Bilateral lower extremities (rarely upper extremities) symmetric involvement
37
what is worse is pitting or non pitting edema worse
pitting is harder to treat
38
Lymphedema vs Lipedema - Cellulitis
lymph - common lip - rare
39
Lymphedema vs Lipedema - Pain on pressure
lymph - absent lip - present
40
Lymphedema vs Lipedema - Distal edema in the foot
lymph - present lip - absent
41
Lymphedema vs Lipedema -Stemmer sign
lymph - + lip - (-)
42
what is Volumetric Measurements
Immerse the limb in a tank of water to a predetermined anatomical landmark and measure the volume of water displaced
43
what are Bioimpedance Measurements
Use of a low level alternating electrical current to measure the resistance to the flow through the extracellular fluid in the upper extremity
44
how do we read Bioimpedance Measurements
The higher the resistance to flow, the more extracellular fluid present
45
what measurement do we use for proximal UE/LE lymph
Girth Measurement
46
what measurement do we use for distal UE/LE lymph
volumetric
47
what measurement do we use for pre/post surgery lymph
Bioelectric Impedance
48
what measure do we use for Lymphatic Insufficiency
Lymphoscintigraphy Measured during rest and exercise, identifies lymphatic insufficiency
49
what is dopplers US used for
use to measure the blood flow through your blood vessels
50
what does being tender to palpation indicate
Indicative of inflammation or infection
51
what does Fixed, hard and non- tender to palpation indicate
Indicative of malignancy
52
where does lymphdema swelling start
distally - where do we assess stremmer sign at fingers and toes
53
what is the progression of edema - pitting or non-pitting first
pitting first that progresses to non pitting
54
Dynamic pressure changes within the body: lymph treatment
diaphragmatic breathing or muscle contractions
55
Manual Lymphatic Drainage: what is cleared first
Proximal areas (trunk, groin, buttocks or axilla) cleared first; distal areas done later. clear the traffic jam
56
Manual Lymphatic Drainage: how do we perform
MLD is performed using circular movements and stroking. Direction of the stroking is Distal to Proximal and towards specific lymph nodes.
57
Phase I: Intensive phase lymph care
*Manual lymphatic drainage (MLD) *Multiple layer compression bandaging *Skin and nail care *Exercise
58
Phase Il: Maintenance phase lymph care
* Self-MLD by the patient Compression therapy * Compression garment during the day * Multiple layer bandaging in the evening/night * Skin and nail care * Exercise
59
Compression therapy: Phase I bandages (Active reduction phase)
use only low-stretch bandages
60
what are low-stretch/short bandages
non-elastic or rigid short stretch compression bandages provide high working pressure (while you’re moving) and low resting pressure (while you’re inactive). Because short stretch compression bandages simultaneously provide pressure and expand, they can help move lymphatic fluid out of a limb.
61
High stretch sports bandage (ACE wraps) reccomended?
no
62
info about short stretch
* Has low resting pressure and high work pressure * From Distal-to-Proximal direction * Used during day and night
63
Exercises: for lypmhdema
Active ROM, stretching, low intensity resistance exercises - performed wearing compression garment or bandages * Proximal-to-Distal direction
64
why do we look at nail and skin care for lymph
Attention to avoid skin breakdown, infection and delayed wound healing
65
should lymph node be mobile
yes
66
should lymph nodes be tender or non-tender
non-tender
67
should lymph node be soft or hard
soft
68
what is lymphadenopathy
Enlarged lymph nodes
69
what is the goal of the intensive phase of decompression therapy
reduction as much as we can
70
what type of bandages are used in phase 1 treatment
short/low stretch bandages
71
when are high stretch bandages used
after an ankle sprain it has a lot of stretch - low working pressure and high resting pressure
72
should you do proximal or distal exercises first
proximal then distal breathing exercises before arm exercises
73
what kind of compression do we use in phase 2: matinence phase of lymph
compression garment - these are worn all day no longer using short stretch during the day short stretch are worn at night
74
What finger and toe do we test stemmed sign
2nd toe 3rd finger
75
If someone has a positive stremmers sign, does that mean they have brawny or pitting edema?
Brawny
