Edema vs Lymphedema

Fluid Balance
Fluid moves freely b/t interstitial & intravascular spaces to
maintain homeostasis
4 types of pressure control fluid shifts across the capillary
membrane
Capillary hydrostatic pressure( the internal fluid pressure on
the capillary membrane)
Interstitial pressure (external fluid pressure on the capillary
membrane
Osmotic pressure-(fluid attracting pressure from protein
concentration within the capillary

Fluid Balance Interstitial osmotic pressure (the fluid attracting
pressure from protein concentration outside the capillary
Normally capillary hydrostatic pressure is >than plasma osmotic pressure at the capillary’s arterial end forcing fluid out of the capillary.
Capillary end the reverse is true(plasma osmotic pressure is >)
Edema results when balance is impeded with increased capillary permeability, lymphatic obstruction, increased capillary hydrostatic pressure, decreased plasma osmotic or interstitial fluid pressure

Lymphedema Excessive and persistent accumulation of extravascular
and extracellular fluid and proteins in tissue spaces
Caused by a disturbance of the water and protein balance across the capillary membrane
Increased concentration of proteins draws greater amount of water into interstitial spaces
Exceeds transport capacity of the lymphatic system, leading to lymphedema

Contributing factors for
Lymphedema Congenital Malformation
Infection and Inflammation
Obstruction or Fibrosis
Trauma, Surgery, Neoplasms
Radiation Therapy
Surgical Dissection of Lymph Nodes
Chronic Venous Insufficiency

Edema vs Lymphedema Normal response to inury. As
healing occurs fluid
decreases
Excess tissue fluid not yet
returned to circulatory syst.
Caused by circulatory
system problems such as
chronic venous insuffiency,
Does not leave a mark when
press (nonpitting)
Can be relieved by diuretics
in some cases
Lymphatic system is
impaired
Excess lymph trapped in
tissue
Body responds with slow
healing and at risk for
infections
Leaves a mark
Harmed by diuretics
