Hypertonic dehydration diagnosis and treatment
Hypertonic dehydration is diagnosed according to the general medical history and clinical manifestations. Laboratory tests: a. a high specific gravity; b. at many higher serum sodium 150mmol / L or more; c. red blood cell count, hemoglobin, hematocrit increased slightly.
Hypertonic dehydration treatment is to remove the cause, so that fluid loss is no longer sick. The loss of the liquid has been added to intravenous infusion 5% glucose or aqueous solution of salt and low permeability. Added an estimated amount of lost liquid has two ways: a. In accordance with the severity of clinical manifestations, according to the weight loss to estimate the percentage. Medium such as dry weight of the water volume of 4% ~ 6%, about rehydration 2.5L ~ 3.0L. b. According to the measured blood Na + concentration to calculate. Added water (ml) = [measured value of sodium (mmol) - the normal serum sodium (mmol)] × weight (kg) × 4.
At the same time to add water to fill the appropriate sodium, to correct the lack of sodium. At the same time there is such as to correct potassium deficiency should be in the urine of more than 40ml / h after the potassium to avoid excessive potassium. After rehydration treatment, has yet to be corrected acidosis can supply sodium bicarbonate solution.
