Document Summary
Contraction of fluids in the extracellular compartment. Expansion of fluids in the extracellular compartment. Increase in sodium concentration in ecf, water flows from icf to ecf compartment, cells shrink. Decreased water intake from impaired thirst or unconsciousness. Water flows from icf to ecf compartment. Increased nerve cell water impaired sensorium (confusion, lethargy, + romberg sign, seizures, coma) + romberg sign: close their eyes, try to stand, difficult time balancing/maintaining posture. More dangerous than hypernatremia because of potential for hernias. Drop in sodium concentration in ecf, water flows from ecf to icf, cells become swollen. Water flows from ecf to icf compartment. Reduced urine output (exercise, heat exposure, siadh) May be hypovolemic, euvolemic (normal volume can be due to medication interaction) or hypervolemic (fluid overload); can be acute or chronic. Ecstasy: how is hyponatremia treated? (consider acute versus chronic hyponatremia. ) Slow rehydration over 48 hrs with iv of 5% dextrose in 0. 9% nacl.
