Q

The part of the circulatory system that is concerned especially with scavenging fluids and proteins which have escaped from cells and tissues and returning them to the blood, with the phagocytic removal of cellular debris and foreign material, and with the immune response and that consists especially of lymphoid tissue, lymph, and lymph-transporting vessels.

Q

When and why does high protein edema develop?

A

After a week; develops because excessive plasma proteins become trapped in interstitium and can’t move out of damaged lymph system.

Q

Pitting edema

Q

Does cold reduce edema? explain

A

yes, but it can also turn skin red and cause inflammation. (be mindful of this).

21
Q

Figure of 8 Method

A

method of measuring edema with a tape measure; used when whole hand is swollen.

22
Q

volumeter

A

method of measuring edema in which whole hand/arm is placed in water.

23
Q

Name 3 traditional techniques to reduce edema.

A
  • elevation
  • AROM
  • retrograde massage
24
Q

Retrograde massage

A

Stroke DISTAL to PROXIMAL, applying slight pressure trying to move fluid out. Good easy first step.

25
Q

How can we reduce swelling under a splint?

A

Compression glove under a splint.

26
Q

High Volt Pulses Galvanic Stimulation

A

helps intrinsics of hand contact and relax.

27
Q

Contrast baths

A
  • used for early edema
  • warm water 4 mins, cold water 1 min (for ex.)
  • no evidence, but some pts. say it works
28
Q

Which pts. can’t use contrast baths?

A

pts. with Raynaud’s Disease due to circulation.

29
Q

a technique to decrease sub-acute persistent and chronic hand edema post surgery, trauma, or stroke.

A

Manual Edema Mobilization (MEM)

30
Q

Does MEM work for lymphedema?

A

No

31
Q

Describe MEM techniques.

A

Rest hand underneath pts. arm. Put half of hand weight on top of pts. arm. Do a series of “U”s. At the end pt. should raise arm and open and close hand.

32
Q

MEM includes the use of what 3 things?

A

exercises, light skin-traction, massage techniques following the lymphatic pathways, and the use of low-compression garments.

33
Q

MEM should not be used on pts. with what 8 conditions? (contraindications)

A
  • inflammation, open wounds
  • blood clot, hematoma
  • active cancer
  • CHF, cardiac problems
  • inflammatory stage of wound healing
  • renal failure, kidney disease
  • pulmonary problems
  • post mastectomy lymphedema
34
Q

post surgical compressive bandage

A

a type of soft splint bandage consisting of many layer of soft material wrapped around a joint or extremity.

35
Q

what is the purpose of a post surgical compressive bandage?

A

to compress and to limit mobility in order to provide support, reduce bleeding, and limit swelling following surgery or trauma.

36
Q

a collection of protein-rich lymphatic fluid, usually in the arm or leg which accumulates within the soft tissues. it’s caused by interruption of normal lymphatic flow which can be due to surgery, radiation, infection of trauma.

A

lymphedema

37
Q

primary lymphedema

A
  • resulting from lymphatic dysplasia
  • can be present at birth
  • can develop later with no apparent cause
38
Q

secondary lymphedema

A
  • more common

- causes known ex: surgery, radiation treatment for cancer, after injury - trauma, scarring, infection of lymph system

39
Q

What causes lymphedema?

A

-the amount of fluid going into the arms or legs is greater than the amount that can go out bc of the damage to the transport system.

40
Q

Manual Lymphatic Drainage (MLD)

A
  • rerouting the fluid
  • gentle manual technique
  • activates lymph system
  • usually not done as only treatment modality
41
Q

Complete Decongestive Therapy (CDT)

A
  • most successful for chronic lymphedema

- gentle, non-invasive and highly effective

42
Q

Name the 5 components of CDT

A
  • MLD (manual lymphatic drainage)
  • bandaging
  • exercise
  • skin care/nail care
  • education
43
Q

a very gentle type of massage therapy used to drain excess fluid from the body and improve the overall functioning of the lymphatic (immune) system. Most commonly used to treat lymphedema, which is characterized by the blockage of lymph nodes in the arms and legs.

A

Manual Lymph Drainage (MLD)

44
Q

most successful treatment for chronic extremity lymphedema. Post mastectomy lymphedema and other related conditions respond extremely well to this gentle, non-invasive and highly effective therapy.

A

Complete Decongestive Therapy (CDT)

45
Q

Which medications should not be used to treat lymphedema?

A

diuretics (makes condition worse)

46
Q

Pneumatic compression pump

A

compresses and relaxes to reduce/control swelling

47
Q

Name 6 guidelines for lymphedema patients (patient education).

A
  • skin - avoid trauma/injury to reduce risk of infection.
  • lifestyle - build up duration and intensity of activity
  • avoid limb constriction
  • use compression garments
  • avoid extremes of temperature
  • LE practices - NO prolonged sitting, standing, crossing legs, wear good shoes, compression garments.
48
Q

How would you start OT on someone with edema?

A
  1. measure the edema (tape measure, volumeter)
  2. measure AROM
  3. assess pain levels
  4. assess sensibility
  5. treatment - elevation, compression glove, positioning (Splint) - safe position but not 24/7
