Riella Disturbios Hidroeletroliticos – Capítulo do livro de Nefrologia de Riella

A sixty-year-old white female, recently diagnosed with glioblastoma multiforme and treated with temozolomide, presented to the oncologist’s office disturbiio of drowsiness. The inadvertently rapid correction of chronic hyponatremia may severely reduce neuron volume and result in brainstem demyelination, especially at the pons pontine myelinolysis We need better proof of its existence. Berl T, Rastegar A. Up to Date, v. One case of subarachnoid hemorrhage shows that, naturally, it also happens in HIV-positive individuals.

Hyponatremia in marathon runners. Nidroeletrolitico replacement in volume depletion. Nevertheless, it is quite clear that improper management of a hyponatremic patient may result in severe neurologic damage or death. A potential pitfall in therapy. Tex Med ; Since the serum sodium concentration is the main determining factor of serum osmolality, true hyponatremia is accompanied by hypoosmolality Formula 3.

Regardless of the approach, the phsyician must always be vigilant to avoid an overly rapid correction of chronic hyponatremia, to minimize the risks of pontine myelinolysis.

Hence, hyponatremia may be the result of any of the situations shown in Table 1. In such situations, urine will be dilute, indicating that kidneys are trying to excrete excess water.

More recently, hyponatremia was associated with increased mortality in chronic kidney disease patients on hemodialysis. Nielsen S, Agre P.

Mortality associated with low serum sodium concentration in maintenance hemodialysis. If formulas are used, the rate hidroeletrolltico degree of correction will be underestimated because they do not take into account the electrolyte free water diuresis that occurs in response to the reversal of hypovolemia. The association persists when analyzed in specific subgroups of diseases, such as neoplasms, congestive heart failure CHF and cirrhosis.

It is associated with several unfavorable endpoints such as: Since both formulas are imprecise and present several limitations, some authors suggest simpler approaches for the use of hypertonic saline. JAMA ; Depending on the severity and duration of hyponatremia, symptoms may range from absent to full-blown encephalopathy, coma and seizures. Hemodynamic assessment in dosturbio critically ill patient. Waiting for more specific manifestations may delay the diagnosis of treatable diseases, like bacterial or fungal meningitis.

Severe hyponatremia and pulmonary edema during hysteroscopy]. Mechanisms Involved in Fluid and Solute Imbalance. Water excess results in dilution of serum sodium and hyponatremia. A detailed history, concerning mode of installation, previous diseases, associated symptoms and drug exposure is fundamental, but not ever obtainable.

For the same patient, the administration of 1 L hypertonic saline, which contains 1, mosm of solute, would result in an obligatory excretion of 1. Treatment The proper management of hyponatremia requires the consideration of several aspects, such as the duration and severity of the disorder, the presence or hidrieletrolitico of symptoms and etiological diagnosis.

These symptoms are not specific, and may be interpreted as clinical manifestations of the underlying disease. Joyce SM, Potter R. One strategy would be to administer 0. Atualidades em Nefrologia, Eds: The conclusion is that hyponatremia should be interpreted as a disorder of water excess rather than sodium deficit.

Serum creatinine must be measured to evaluate renal function. By reversing the hypovolemia, normal saline removes the hidroeletroliyico stimulus for ADH secretion. In this situation, use of AZT may diminish the pleocytosis and the protein alterations, confirming that the alterations were induced by the own viruses 5.

The Case A year-old male with hyponatremia. A detailed history, including mode of installation, previous diseases, associated symptoms and drug exposure, is fundamental but not always obtainable. Other factors that might have contributed to the overly rapid correction in hidroeletrolitixo case included the withdrawal of HCTZ, reversal of hypovolemia and water restriction.
