Hypervolemic hypernatremia is the most common type of hypernatremia in the intensive care unit.

摘要: A high incidence of hypervolemic hypernatremia has been described in patients recovering from acute kidney injury (AKI) intensive care units. However, this limited to only a few cases. One hundred fifty adult AKI the unit single institution during 6-year period, who developed course their illness, were investigated. Serum and urine electrolytes, osmolality, urea nitrogen creatinine measured. The weights these at time development presentation hospital also Even though was mild most (146–160 mEq/L), average rise serum sodium concentration 14.5 ± 7.1 mEq/L. Of 34 had all urinary studies available, osmolality 436 ± 128 mmol/kg which 172 ± 54 mmol/L contributed by sodium, potassium accompanying anion. Another 204 ± 96 mmol/L accounted for (mainly urea). Almost hypervolemia as evidenced presence edema an weight gain more than 9 ± 11 kg between onset despite likely having lost muscle mass being several days. data available 54 patients, eight hypernatremia. Hypervolemic is far common cause unit. are negative fluid balance hypernatremia, earlier saline administration caused massive volume overload ongoing losses. Post-AKI diuresis face inability maximally concentrate because renal failure often leads mainly elevations concentration. solute concentrations with little electrolytes present urine.
