*****Causes of edema
|
1. Increased Capillary pressure
2. Decreased colloidal osmotic pressure 3. Increased capillary permeability 4. Obstruction of lymphatic flow |
|
|
Increased capillary pressure:
Arteriol dilation |
Allergic responses
Inflammation |
|
|
Increased capillary pressure:
Venous obstruction |
Hepatic obstruction
Heart failure Thrombophlebitis |
|
|
Increased capillary pressure:
Increased vascular volume |
Heart failure
Increased levels of adrenocortical hormones Premenstrual sodium retention pregnancy environmental heat stress |
|
|
Increased capillary pressure:
Effects of gravity |
Prolonged standing
|
|
|
Decreased colloidal osmotic pressure:
**decreased production of plasma proteins** |
Liver disease
Starvation or severe protein deficiency |
|
|
Decreased colloidal osmotic pressure:
increased loss of plasma proteins |
Protein losing kidney diseases
extensive burns |
|
|
**Increased Capillary Permeability**
|
Inflammation
Immune Responses Neoplastic disease Tissue injury and burns |
|
|
Obstruction of lymphatic flow
|
Infection or disease of the lymphatic structures
Surgical removal of lymph nodes |
|
|
Why do you need to control edema?
(swelling) |
1. Pain
***2. Increased diffusion (oxygen has to travel farther to get to cells) 3. impinges on circulation (squeezes) |
