How does hand face crural oedema return a responsibility?
summary
The edema caused by the increase of vascular wall permeability, the protein content in the edema fluid is higher, and the relative density is higher than 1.018, which is called exudate, such as edema fluid in inflammation. The edema caused by the increase of capillary hydrostatic pressure or the decrease of plasma colloid osmotic pressure, the protein content in the edema fluid is low, and the relative density is less than 1.015, which is called leakage fluid, such as ascites caused by liver cirrhosis. The protein content in the edema produced by blocked lymphatic return was also higher. Next, I will introduce to you how hand face foot edema is going on
How does hand face crural oedema return a responsibility?
First: skin edema is an important sign of systemic or local edema. The edema area is swollen due to the accumulation of edema fluid. Pressing hard can leave depression or indentation, which is called depression edema.
Second: but before the appearance of depression edema, tissue fluid increased and reached 10% of the original body weight, which is called recessive edema. This is because in the early stage of edema, colloidal substances (hyaluronic acid, collagen, mucopolysaccharide, etc.) in the interstitial tissue can absorb the edema fluid and produce self expansion. When it exceeds its absorption capacity, it will form free liquid and appear concave edema.
Third: Mucinous edema caused by hypothyroidism and elephantiasis caused by blocked lymphatic reflux. Due to the high protein content in tissue fluid, the edema fluid is not easy to move, which is characterized by tight skin without obvious depression. It belongs to non depressed edema.
matters needing attention
Cardiac edema is mainly distributed in the drooping part of the body, renal edema first appears in the eyelid or facial tissue loose parts, liver edema is mainly ascites.
