Serial values of investigations done in the patient Click here to view. Unexpectedly high Frequency of reset osmostat and cerebral-renal salt wasting in non-edematous hyponatremia: Rather the evidence of negative salt balance and reductions in both plasma and total blood volume in these patients is more consistent with a diagnosis of cerebral salt wasting.

Wastinf is mounting evidence to prove the ineffectiveness of the volume approach to hyponatremia. Volume depletion and natriuresis in patients with a ruptured intracranial aneurysm. Table 3 Summary of extracellular volume expansion with isotonic, hypotonic and hypertonic saline on fractional excretion of sodium [FEsodium] and urate [FEurate] at control and experimental Exp.

Evaluation of vitamin K status and rationale for vitamin K supplementation in dialysis patients.

Cerebral salt wasting versus SIADH: what difference?

By contrast there were no differences in ANP concentration or digoxin-like immunoreactive substances between the two groups. Maesaka JK, Fishbane S.

Nevertheless modest expansion of the intravascular volume results in increased glomerular filtration rate and increased renal plasma flow. Management of neurosurgical patient with hyponatremia and natriuresis.

On hospital day 10 the patient was noted to be confused and hypotensive. In cetebral regard one could speculate that teleologically the development of renal salt wasting and resultant volume depletion in the setting of intracranial disease is a protective measure designed to limit extreme rises in intracranial pressure.

It determines the net transport of urate without distinguishing what is secreted or reabsorbed and can be readily determined by collecting blood and spot urine at the same time. ANP and BNP have also been waasting capable of directly decreasing autonomic outflow through effects at the level of the brain stem [ 1718 ].

SIADH versus Cerebral Salt Wasting

If so, fluid restriction would tend to aggravate an already decreased plasma volume. These same investigators then examined sodium balance in a monkey model of subarachnoid haemorrhage [ 12 ]. Ann Indian Acad Neurol ; Eur J Intern Med ; Abstract Hyponatremia is the most common electrolyte abnormality. This has been reported with increased morbidity when the patient with RSW was fluid restricted for an erroneous diagnosis of SIADH [ 12242530 ]. Sodium and fluid loss in the urine was matched by intravenous replacement in order to prevent the development of hyponatraemia.

SIADH versus Cerebral Salt Wasting

Previous studies have demonstrated that a sodium waasting patient will virtually eliminate sodium from urine until the sodium losses have been replaced [ 151617 ].


In this regard, hypokalaemia has not been a feature of CSW and in the current case the serum potassium was actually slightly increased.

In two patients with SIADH and increased blood volumes, saline infusion failed to dilute their urine or correct their hyponatremia [ 11 ]. Isr J Med Sci. A syndrome of renal sodium loss and hyponatremia probably resulting from inappropriate secretion of antidiuretic hormone.

Raven Press, New York: The high urine chloride and presumably sodium concentration in urine would, thus, have been consistent with RSW and xerebral term CSW was thus derived. Shaded areas represent normal ranges.

In addition, a fourfold increase in bone fractures in elderly hyponatremic patients and increased osteoporosis with chronic hyponatremia has been reported [ 5722 ]. A syndrome of renal sodium loss and hyponatremia probably resulting from inappropriate secretion of antidiuretic hormone.

Cerebral salt wasting versus SIADH: what difference?

Palmer; Hyponatraemia in a neurosurgical patient: On an average of 7 wawting following the event, nine patients developed hyponatraemia that met the criteria for a diagnosis of SIADH. A salt-wasting syndrome associated with cerebral disease. Receive exclusive offers and updates from Oxford Academic.
