Isoosmotic dehydration?
summary
Isoosmotic water shortage is also called acute water shortage or mixed water shortage. And this kind of situation may cause the patient's body to have the question generally, this kind of water shortage is most likely to occur in the surgical patient. At this time, water and sodium are lost in proportion, so serum sodium is still in the normal range, and the osmotic pressure of extracellular fluid can also be kept normal. However, the amount of extracellular fluid decreased rapidly due to isotonic dehydration. Now let me talk about the symptoms of isotonic dehydration?.
Isoosmotic dehydration?
First, the patient is not thirsty, and has symptoms of oliguria, anorexia, nausea, fatigue, dry tongue, eyeball depression, dry skin, relaxation, etc.
Second, if the body fluid loses more than 5% of body weight in a short time, that is, 25% of extracellular fluid is lost; The patient had symptoms of insufficient blood volume, such as pulse rate, cold and wet extremities, unstable or decreased blood pressure.
Third, body fluid loss continued to reach 6% - 7% of body weight; 30% - 35% of extracellular fluid was lost; Shock has been shown to be very severe. It is often accompanied by metabolic acidosis.
matters needing attention
Because of the above reasons, the decrease of extracellular fluid volume in hypotonic dehydration is more significant than that in isotonic dehydration.
