Cerebral salt wasting urine sodium
What is treatment for Cerebral salt wasting?
Treatment of cerebral salt wasting is through frequent hydration to prevent dehydration plus medications.
What is the pathophysiology of Cerebral salt wasting?
Pathophysiology of cerebral salt wasting. The mechanism by which cerebral disease leads to renal salt wasting is not well understood . The most likely process involves disruption of neural input into the kidney and/or central elaboration of a circulating natriuretic factor (Figure 3).
What are mechanisms of Cerebral salt wasting (CSW)?
Cerebral salt wasting (CSW) is a syndrome of hypovolemic hyponatremia caused by natriuresis and diuresis . The mechanisms underlying CSW have not been precisely delineated, although existing evidence strongly implicates abnormal elevations in circulating natriuretic peptides.
What is cerebral salt wasting syndrome?
Cerebral salt wasting (CSW) is another potential cause of hyponatremia in those with CNS disease, particularly patients with subarachnoid hemorrhage. CSW is characterized by hyponatremia and extracellular fluid depletion due to inappropriate sodium wasting in the urine [ 5 ].

4.3. Cerebral Salt Wasting CSW is a disorder characterized by ECF depletion and hyponatremia. It is a true hyponatremia, first described by Peters et al as a cerebral disease causing natri-uresis and diuresis [19]. The pathophysiology is still not yet understood, v-howe er there are two proposed mechanisms. The first theory is that a direct ...

Low serum sodium levels may indicate the possibility of Cerebral Salt Wasting Syndrome (CSWS) - see section below on fluid / electrolyte imbalance. Whether CSWS is a separate clinical entity or another manifestation of DND is unknown, however the volume depletion seen with CSWS exacerbates DND and must be addressed.
