Definition of Lymphedema
Lymphedema is the result of the abnormal accumulation of protein rich edema fluid
Primary or secondaryAfflicts approximately 1% of the US
population (2.5 million people)* A SUDDEN ONSET OF EDEMA MUST BE
THOROUGHLY EVALUATED BY A PHYSICIAN

Lymphedema Interventions
Surgery (Debulking, Liposuction) Taking out all the lymphatic with these surgeries
Medication (Diuretics, Benzopyrones) Takes out all the water, but leaves lymphatic's with
protein rich lymph fluid.
Pneumatic Compression Pump May harden the tissue or destroy lymph collectors,
and leave person immobile for a couple of hours.
COMPLETE DECONGESTIVE THERAPY Removes proteins from the system.
![Page 28: Treatment of Lymphedema](https://reader036.vdocuments.us/reader036/viewer/2022081420/56814f32550346895dbcc5c4/html5/thumbnails/28.jpg)
Anti-Edema Medications
Not effective because: Do not allow the proteins to be reabsorbed into the
venous system As long as proteins are stagnate in the interstitial
space the onconic pressure remains high and lymphedema persists
Can worsen Lymphedema in the long run as they increase the concentration of proteins in the interstitial space exacerbating fibrosis

Precaution/Contraindication
Rationale Modification
DVT Do not treat in the area of an acute DVT. Fear is dislodging causing a life threatening emboli
Treat adjacent areasAwait medical clearance prior to treating affected area
Active Infection Do not treat with an active infection. Fear of spreading infection
Wait until appropriate antibiotic therapy has been initiated and show signs of resolving
Open wound Do not treat areas with breaks in the skin
Treat adjacent areas of intact skin
Metastatic Disease
Fear of spreading cancer Palliative care; Team decision
Congestive Heart Failure
Fear of systemic fluid overload Must be controlled, then treat conservatively and monitor
Asthma Fear that parasympathetic stimulation will provoke an asthma attack
Must be controlled, then treat conservatively and monitor
AAA, Diverticulitis, IBS, Crohn’s disease
Deep abdominal techniques may aggravate or worsen these conditions
Do not perform deep abdominal techniques
Pregnancy Fear deep abdominal techniques may harm the fetus or uterus
Do not perform deep abdominal techniques

Protect the skin : Individuals that have had lymph nodes removed are at risk for lymphedema. To minimize this risk the following precautions should be followed:
Keep arm clean and dry.Apply moisturizer daily to prevent
chapping/chaffing of the skin. Balance lotion
Attention to nail care; do not cut cuticles.Protected exposed skin with sunscreen
and insect repellent.Use care with razors to avoid nicks and
skin irritation.Avoid punctures such as injections and
blood draws.

Wear gloves while doing activities that may cause skin injury
If scratches/punctures to skin occur, keep clean and observe for signs of infection.
Gradually build up the duration and intensity of any activity or exercise, and monitor arm during and after for any change in size, shape, firmness or heaviness.
Avoid arm constriction from blood pressure cuffs, jewelry and clothing
Avoid prolonged (>15 minutes) exposure to heat, particularly hot tubs and saunas
Airplane flights: due to decrease pressure in cabin, will need a compression sleeve

Manual Lymph Drainage (MLD)
a manual technique to mobilize fluid in the lymph system, by movement of proteins and fluid into the initial lymphatic vessels. This manual technique is done lightly and slowly.
![Page 43: Treatment of Lymphedema](https://reader036.vdocuments.us/reader036/viewer/2022081420/56814f32550346895dbcc5c4/html5/thumbnails/43.jpg)
Manual Lymph Drainage (MLD)
Basic Principles: 1. Proximal area is treated first, clearing first the
adjacent and unaffected lymphotomes, then proximal sections of the affected lymphotomes.
2. The direction of pressure depends on the areas of edema and the direction should always be towards a cleared lymphotome.
3. Technique and variations are repeated rhythmically. 4. Pressure phase lasts longer than relaxation phase. 5. As a rule there should be no reddening of the skin
![Page 44: Treatment of Lymphedema](https://reader036.vdocuments.us/reader036/viewer/2022081420/56814f32550346895dbcc5c4/html5/thumbnails/44.jpg)

Compression bandages
Compression bandages have been shown to produce a micromassage effect that improves lymph transport.
Increase temperature of up to 5 degrees enhances the lymphangion mobility
![Page 58: Treatment of Lymphedema](https://reader036.vdocuments.us/reader036/viewer/2022081420/56814f32550346895dbcc5c4/html5/thumbnails/58.jpg)
Bandages
Resting pressure - Pressure from the outside in the resting position of the muscle. Pressure applied from fascia, bandages
Working pressure - Pressure from the inside when the muscles are active. Pressure generated by the muscles

Types of compression bandages
Elastic high stretch bandage- high resting pressure and low working pressure Not effective for treating lymphedema High resting pressure does not allow the
lymphatics to fill And low working pressure does not increase tissue
pressure effectively enough to influence the lymphatic pump because it stretches when the muscle contracts
![Page 62: Treatment of Lymphedema](https://reader036.vdocuments.us/reader036/viewer/2022081420/56814f32550346895dbcc5c4/html5/thumbnails/62.jpg)
Types of Compression bandages
Low stretch bandage- low resting pressure and high working pressure
low resting pressure allows the lymphatic to fill High working pressure compresses the lymphatic vessels
between the muscle the bandage facilitating lymphatic flow
![Page 63: Treatment of Lymphedema](https://reader036.vdocuments.us/reader036/viewer/2022081420/56814f32550346895dbcc5c4/html5/thumbnails/63.jpg)
Low Stretch Compression Bandages
Form a semi rigid support which causes an increase in interstitial pressure when the muscle contracts
When a patient wears low stretch compression bandages while sleeping or resting the increased interstitial pressure will reduce the amount of fluid and protein leaving the arteriole (ultra filtration) and less edema is formed
When a patient wears low stretch compression bandages during activity the increased interstitial pressure not only reduces ultra filtration but increases reabsorbtion into the lymphatic system which decreases lymphedema and well as venous edema

Must use Low stretchAlways start distally and proceed
proximallyMaintain moderate tensionAvoid creases and foldsUse tape to secure…not clips or
pinsApplied with greater pressure
distally than proximallyDo not extend bandage to maximal
length

Principles of Bandaging – con’t
Check pressure gradientPlace more layers for increase
compression rather than applying them more tightly
Fill indentations with padding or foam pieces
Cover as much of the limb as possible
Compression to be worn until next visit
Exercise with bandages on to take advantage of muscle pump effect

Bandaging SuppliesScissorsTape Lotion – low pHTubular bandage
Protects the skin, skin hygiene, absorbs perspiration
Elastic gauze/finger/toe wraps/CobanPadding – Artiflex or foam
Prevents indentations in skin, equalizes pressure, protects tender areas
Low stretch compression bandages 6 cm: foot, hand 8 cm: ankle, forearm 10 cm: lower leg, upper arm 12 cm: upper thigh

When to instruct the patient to remove the bandages
If the patient gets short of breath or has heart palpations
If the fingers/toes are numb, blue or tingling
If the wraps fall offIf the patient is experiencing too much pain

Compression Therapy
Compression therapy is the application of external pressure on body tissue to support the elasticity of the skin and its underlying vessels
Phase I with Compression BandagesPhase II with medical compression Garments
![Page 71: Treatment of Lymphedema](https://reader036.vdocuments.us/reader036/viewer/2022081420/56814f32550346895dbcc5c4/html5/thumbnails/71.jpg)
Rationale for using compression therapy:
Compression therapy directly effects the underlying lymphatic vessels, veins and tissue.
Improves the efficacy of the muscle pump by creating a semi-rigid support for the muscle to work against
Causes a mild increase in total tissue pressure
Improves and maintains the shape of the limb

Compression Garments
Not designed to decrease edema- only to maintain the edema reduced by the treatments
Increases reabsorbtionIncreases tissue pressureready made vs. customill fitting garment is worse than not wearing
one at all

Lympha Press
Pressure range is 20-180 mmHg. Pressure is distributed into overlapping air
compartments which are contained in a special sleeve. The compartments are sequentially inflated, from distal
to proximal, massaging the limb in a proximal direction. The overlapping compartments prevent any gaps in
treatment, to achieve a maximal and safe reduction of the lymphedema.
The treatment cycle starts by filling the distal compartment first and continues inflating the remaining compartments in sequence during the first 24 seconds until all are full.
The pressure is held in all compartments for 2 seconds, then deflates for four seconds which completes the 30 seconds cycle. The cycle then repeats itself.

LASER
Another new frontier in the treatment of lymphedema involves using the laser.
From various trials lasers appear to help lymph flow, shown to be effective improvement of wound healing, and it has been used effectively in treating edema from DVT’s.
The FDA has approved a laser device to be used in the treatment of post-mastectomy arm lymphedema. Clinical trials are currently underway for leg lymphedema.
Lymphedema and its complications can causing "scarring" of the lymphatic system. The laser is useful in removing the scar tissue, thereby helping lymph flow.
