“…Lee et al recognized severe hypernatremia as an independent risk factor of mortality in the patients admitted to the neurosurgery intensive care unit [19]. Cintra et al reported a higher incidence of serum Na disturbance in patients who died in the first week after TBI compared to survivors [20]. The discrepancy between our findings and the results of mentioned studies may be due to the difference in the study population and duration of follow-up period; in our study, DAI patients were adult and all had consciousness levels below 15, while Yousefichaijan et al assessed 110 patients aged one month to 18 years.…”

“…The maximal antidiuresis additionally occurs at serum concentrations of 1-3 pg/ml. At some point in certain stressors, such as severe nausea, vomiting and surgical procedure, serum AVP levels can temporarily reach 50 pg/ml [14]. In another study, six cases with a history of increased urinary frequency during migraines had been reported to be associated with severe diuresis and natriuresis and a significant decrease in urinary AVP [11].…”

“…[3], [4], [5] and contribute to the high morbidity and mortality rates observed in these patients. [6] K is the major intracellular cation, with relatively low extracellular levels. Changes in K levels can affect muscle contraction and nerve conduction; hypokalemia is associated with cardiac arrhythmias (Especially in patients with ischemic heart disease and left ventricular hypertrophy), muscle weakness (Including weakness of respiratory muscles), rhabdomyolysis, renal failure, and hyperglycemia.…”
