Ross, Michael G., Mina Desai, Catalina Guerra, and Shengbiao Wang. Prenatal programming of hypernatremia and hypertension in neonatal lambs. Am J Physiol Regul Integr Comp Physiol 288: R97–R103, 2005. First published September 16, 2004; doi:10.1152/ ajpregu.00315.2004.—Maternal water restriction and the accompanying dehydration-induced anorexia may induce long-term physiological changes in offs...
BACKGROUND Hypervolemic hypernatremia is caused by an increase in total exchangeable Na(+) and K(+) in excess of an increment in total body H(2)O (TBW). Unlike patients with hypovolemic or euvolemic hypernatremia, treatment needs to be targeted at correcting not only the elevated plasma Na(+) concentration, but also there is an additional requirement to achieve negative H(2)O balance to correct...
Total body water and tonicity is tightly regulated by renal action of antidiuretic hormone (ADH), reninangiotensin-aldosterone system, norepinephrine and by the thirst mechanism. Abnormalities in water balance are manifested as sodium disturbances--hyponatremia and hypernatremia. Hyponatremia ([Na+ < 136 meq/ l]) is a common abnormality in hospitalized patients and is associated with increased ...
OBJECTIVE To determine the sensitivity to an equal dose of ketamine/xylazine injection at anesthetic dose in a chronic model of hypernatremia. METHODS This study was conducted at the Department of Physiology, Zanjan University of Medical Science, Zanjan, Iran in 2004. Sixty male Wistar rats, weighing 250 +/- 20 g were randomly allocated to 3 groups. The control group was provided with tap wat...
CONTEXT Central diabetes insipidus (CDI) is a rare cause of hypernatremia during the neonatal period. The diagnosis is particularly difficult in very low birth weight (VLBW) newborns. CASE REPORT We report on a preterm newborn who presented CDI soon after birth. On the third day of life, signs of dehydration were present despite normal fluid supply. The diuresis rate was 4.4 ml/kg/h. Although...
