Lymphedema Lecture during Lab on 10/12 Flashcards
What are two causes of lymphedema?
- increase in volume of lymph produced
2. Major reduction in capacity for lymph transport
What % of US pop has lymphedema?
1%
1999 World Wide Incidence
Parasite caused 90 mil case
Breast Cancer caused 20 mil cases
Primary (birth defect) caused 2-3 million cases
What % of women with breast cancer will develop some stage of lymphedema?
25-49%
Does Complete Decongestive Therapy (CDT) have side effects?
According to the PPT, no.
What is the gold standard of treatment?
CDT
What are the 4 components of CDT? (Plus one she added, so 5 total)
Manual Lymph Drainage (massage) Compression bandaging Remedial Exercise Meticulous Skin and Nail Care (Education of Self Care)
*MLD, compression, exercise, skin care
What are the two phases of CDT?
- Active Phase (3-5x week)
2. Maintenance phase
What makes up Phase 1 (active phase)?
Meticulous skin care
MLD
Bandaging
Exercise
Self wrapping and self-massage
—
Lasts 2 to 12 weeks depending on the amount of swelling and tissue firmness.
Complete decongestive therapy for one-hour sessions, 4 to 5 days per week.
Bandages with foam are worn 23 hours per day.
What makes up phase 2 (maintenance)
Compression Garments (days)
Bandaging (nights)
Skin care
Exercise (daily)
MLD as needed
—
In order to prevent the area from swelling constant attention is needed.
Elastic compression garments that fit like a second skin are worn during the day.
Often bandages with foam are worn at night to decrease daily daytime swelling.
Exercises are done while wearing compression.
Self manual lymphatic drainage is done for 20 minutes per day.
What are the 4 stages (1+3) of lymphedema?
Pre-Stage: Latency Stage
First Stage: Pitting Edema
Second Stage: Spontaneously Irreversible Lymphedema
Third Stage: Lymphostatic Elephantiasis
What happens during Stage 1
Symptoms worsen during the day.
Reversible
Relieved w/ elevation
Stage 2?
Skin hardens and no longer resolves upon waking. If skin is pressed upon, an indentation will remain. Not resolved with elevation
Stage 3?
Skin changes –> textured
lymphostatic elephantiasis, is nonpitting edema. At this point the disease has progressed to the point where permanent skin changes appear very hard. It is difficult to grasp the skin of the affected area with two fingers.
How does MLD work? Where does the lymph go?
Lymph flows around blocked areas and into more centrally located healthy lymph vessels
Advantages and disadvantages of MLD?
Improved lymph production
Inc lymphangio-motoricity (inc contraction of lymph vessels)
Inc volume transported in lymph system
Special techniques help break down fibrotic areas
Promotes relaxation
Analgesic effect
NO KNOWN DISADVANTAGES!
General contraind.?
heart problems acute infection renal disease maligant disease antibiotics --- neck: arrhythmia Age 60+ thyroid problems Hyper or hypo thyroidism --- abd: preg or menstrating recent abd surgery Crohn's Diverticulitis Cirrohsis unexplained pain aortic aneurysm Radiation fibrosis
What bandages are used in compression? What is enhanced and/or maintained
Short-stretch
*Diffusion and osmosis are enhanced and maintained
What are overall CDT benefits in wound care? (due to edema reduction)
Improved tissue-gas exchange, acid-base balance, bacterial dynamics, cellular transport, increased PO2 (coolagen cross linking, angiogenesis, epithelialization, improved neutrophil function, improved resistance to infection)
When do you wear elastic support garments? How much pressure is needed? How often do you wear it?
AFTER CDT phase 1 to PREVENT limb swelling
Uncomfortable if worn when limb is swollen; does nothing to correct underlying edema (just prevents)
*30-40mmHg - MUST WEAR DAILY
Do you do exercises with bandages and support garments in place?
Yes. Do low exertion, slow, rhythmic. Include diaphramatic breathing. Inc blood flow
Why should you include diaphragmatic breathing?
(increases lymph transported by thoracic duct)
What do you need to consider (what are disadvantages) when using bandaging?
Bulky, hot
Need to use caution with other vascular diseases!
What are advantages to bandaging?
Reduces ultrafiltration rate
Improve efficiency of the muscle and joint pumps
Prevents re-accumulation of evacuated lymph fluid
Helps break up deposits of accumulated scar and connective tissue
During Rx, bandages stay in place until next MLD treatment
