How much lower is serum sodium in hypoosmotic dehydration?

summary

Water and sodium were deficient at the same time, but water deficiency was less than sodium deficiency, serum sodium was lower than normal range, and extracellular fluid was hypotonic. But more attention to their own body, not to check, and eventually developed into a more serious disease. The body reduces the secretion of antidiuretic hormone, reduces the reabsorption of water in renal tubules, and increases the excretion of urine volume, so as to improve the osmotic pressure of extracellular fluid. But the amount of extracellular fluid decreased more. The decrease of interstitial fluid is more than that of plasma, although it can partly compensate the blood volume. Today, let me talk about how much lower the serum sodium of hypotonic dehydration?.

How much lower is serum sodium in hypoosmotic dehydration?

First: mild sodium deficiency patients have fatigue, dizziness, numbness, thirst is not obvious. Serum sodium was below 135 mmol / L and urine sodium was decreased.

Second: moderate sodium deficiency in addition to the above symptoms, often nausea, vomiting, pulse speed, unstable blood pressure, blurred vision, less urine. Serum sodium was below 130 mmol / L.

Third: Patients with severe sodium deficiency are delirious, tendon reflex is weakened or disappeared, and appear numbness, even coma. Shock often occurs. Serum sodium was below 120 mmol / L.

matters needing attention

The key to prevent the disease is vomiting, diarrhea or correct postoperative rehydration.
