Lymphedemasharepoint

  1. 1. Edema vs Lymphedema
  2. 2. 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
  3. 3. 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
  4. 4. Pitting edema
  5. 5. Lymphatic Disorders
  6. 6. 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
  7. 7. 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
  8. 8. 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
