Following correction of HHS, he developed persistent hypernatremia accompanied by large volumes of urine with low osmolality and no response to desmopressin injections. Urine osmolality remained < 300 m Osm/kg after injection of vasopressin. Improvement in serum sodium concentration followed the intake of large volumes of water plus administration of amiloride and hydrochlorothiazide. Severe hyperglycemia may trigger symptomatic lithium-induced NDI years after cessation of lithium therapy. Patients with newonset diabetes mellitus who had been on prolonged lithium therapy in the past require monitoring of their serum sodium concentration after hyperglycemic episodes regardless of whether they do or do not carry the diagnosis of NDI.展开更多

In a country with very limited resources, the prognosis may be favorable in the absence of renal replacement. We report the case of a 63 years old woman, hypertensive and diabetic, admitted to the ICU for unconsciousness. Clinically, neurological examination notes a Glasgow of 8/15 (Y2, V2, M4) and a left hemiplegia. Temperature was 39°C. Diuresis was 100 ml during the first 24 hours. Blood pressure was 90/60 mmHg, tachycardia at 133/min. Cardiac auscultation is normal. Vascular axes were weakly perceptible. Oxygen saturation was 95%. The skin examination notes a dry skin and mucous membranes, a flattening of the superficial veins, sunken eyes and a persistent skin fold. There is no hepatomegaly or splenomegaly, or jaundice. Biological point of view note natremia: 176 mmol/L;osmolarity: 390 mosmol/kg;creatinin: 300 μmol/L;glycemia > 6 g/L;transaminases 217 UI. Diagnostics: malignant hypernatremia with a high plasma osmolarity associated with an acute anuric renal failure, hydro electrolytic disorders, an abnormal liver function, a fever of central origin and a stroke. The treatment consisted of a correction of the electrolyte disorders by infusion of isotonic and hypotonic fluids with insulin. In a country with very limited resources, the severe hypernatremia prognosis associated with anuric acute renal failure may be favorable in the absence of renal replacement.展开更多

Methods Hypernatremic dehydration and hemorrhagic shock models were produced by Trachtma's and Krausz's methods in Sprague Dawley rats. Hemorrhagic changes of mean arterial blood pressure (MABP), left ventricular end diastolic pressure (LVEDP), ±dp/dtmax and heart rate (HR) were registered on polygraph. Plasma Na +, urea lactate and taurine content were assayed. Results After treatment with HS, the hemodynamic changes of hemorrhagic shock rats were significantly alleviated, and tissue fluid redistributed. When the hemorrhagic shock animals were treated with HS containing taurine (HST), in comparison with HS treatment, the hemodynamic improvement and hemodilution were more obvious. When the hemorrhagic animals complicated with hypernatremia were treated with HS, the symptoms of dehydration and shock further deteriorated, when the hemorrhage with hypernatremia animals were treated with an infusion of HST, the symptoms of dehydration and shock were significantly ameliorated. Conclusion The therapeutic effect of HS with taurine is obviously better than HS alone. So when hemorrhagic shock was complicated with hypernatremia, HS with taurine is recommended in stead of HS alone.展开更多
