Hiponatremia é o distúrbio hidroeletrolítico mais comum em pacientes hospitalizados. A presença de hiponatremia está associada a uma série de desfechos. dissociação proteino-citológica relativa (6) e séptica (4), hipoglicorraquia moderada (4%), hipoglicorraquia severa (4%), distúrbio hidroeletrolítico (3%).

We disthrbio that in HIV-positive individuals presenting acute consciousness disturbances there are frequently non-specific results in the CSF analysis that must be weighed against a detailed history and thorough physical examination. Mechanisms Involved in Fluid and Solute Imbalance. Excessive water ingestion and repeated seizures: Mortality after hospitalization with mild, moderate, and severe hyponatremia.

For ICU patients, clinical evaluation of volume status is even more complex and requires the determination of measures of preload, cardiac output or tissue perfusion. Except when hyponatremia develops in the hospital environment for example, in the postoperative periodit is difficult to determine the exact hidroeketrolitico of the disorder.

Cerebrospinal fluid syndromes in HIV-positive patients with acute consciousness compromise

Pseudohyponatremia with high serum osmolality. Hyponatremia is the most common electrolyte imbalance in hospitalized patients.

Hyponatremia, convulsions, respiratory arrest, and permanent brain damage after elective surgery in healthy women. This paper addresses the basic pathophysiologic concepts about hyponatremia followed by hidroeletrolitivo practical approach to its diagnosis and management.

The commonest clinical data were: Chronic infections, use of multiple and toxic medications, nutritional deficits, dehydration, etc. Urinary sodium is low and urine osmolality is high, demonstrating an appropriate salt and water retention in response to the true hypovolemia Hypervolemia History and physical examination suggest an edematous syndrome, such as CHF, cirrhosis or nephrotic syndrome.


Except for acute syphilitic meningitis, all other forms of NS tend to follow a chronic course. Vaptans are inhibitors of vasopressin receptors, which are capable of promoting electrolyte-free water diuresis also known as aquaretics.

The medication list must be reviewed in detail, since several common drugs like anti-inflammatories, antidepressants, anticonvulsants and thiazide diuretics may cause hyponatremia.

The mean age was The viral syndrome may reflect a non-specific reaction not only to virus, but also to fungi, protozoan, mycobacteria or treponemas. Since serum osmolality analysis is not performed in many Brazilian hospitals and laboratories and, when it is, the result may take a whilein practice, it is very common to rule out pseudohyponatremia based on readily available clinical and laboratory data, such as serum glucose, total proteins and fractions, and lipid profile.

Patients with acute kidney injury or chronic renal disease present a global reduction in their capacity to excrete water and solutes. Hyponatraemia in a neurosurgical patient: Waiting for more specific manifestations may delay the diagnosis of treatable diseases, like bacterial hidroeletroitico fungal meningitis. Other factors that might have contributed to the overly rapid correction in this case included the withdrawal of HCTZ, reversal of hypovolemia and water restriction.

New England Journal of Medicine Syndrome of inappropriate secretion of antidiuretic hormone SIADH after treatment with cyclophosphamide, alpha-interferon and betamethasone in a patient with multiple myeloma. Our results suggest that neurocryptococosis may run a more aggressive course, agreeing with Sanchez-Portocarrero The authors emphasize that serum potassium depletion may contribute to hyponatremia, due to sodium shift from the ECF to the ICF.



Diagnosis often defies clinicians, being based more on laboratory tests such as neuroradiological methods and a CSF analysis. Systemic capillary leak syndrome and monoclonal IgG gammopathy.

Among the clinical data, only headache and the presence of an associated pathology was correlated to a CSF data, the positivity of hematoxo.

It is associated with several unfavorable endpoints such as: Depending on the severity and duration of hyponatremia, symptoms may range from absent to full-blown encephalopathy, coma and seizures. Given the high frequency of antibodies against Toxoplama gondii in asymptomatic HIV-positive patients, this might be interpreted with caution 9.

Microcirculatory basis of fluid exchange. The most commonly used equation to estimate corrected serum sodium concentration in a patient with hyperglycemia was developed by Katz, in Formula 4. Sometimes, drowsiness may be interpreted as secondary to depression. 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. Nephrol Ther ; 3 Suppl 2: A recent study illustrated the risk of overly rapid correction of serum sodium with the administration of potassium chloride.

Little, Brown and Co. Since the patient has neither edema nor history or physical findings that suggest hypovolemia, she is believed to be euvolemic. Enviado por Gabriel flag Denunciar. Arq Neuropsiquiatr ; We found little association between clinical data and CSF syndromes.
