Same-Day Initiation of Hormonal Contraceptives. Is this child dehydrated? 10. † These findings are for patients with a serum sodium level in the normal range; clinical manifestations may differ with hypernatremia and hyponatremia. When rehydration is achieved, a normal age-appropriate diet should be initiated. Comparison of nasogastric and intravenous methods of rehydration in pediatric patients with acute dehydration. The infant is currently producing 1 diarrheal stool every 3 hours and refusing to drink. Hyponatremia results in some fluid shifting out of the intravascular space into the interstitium at the expense of vascular volume. 15. Baker MD. Valeria Higinio, MD 1. Practice parameter: the management of acute gastroenteritis in young children. Philadelphia, Pa: Lippincott Williams & Wilkins; 2008:89– 90 Disorders of Sodium and Water Homeostasis. Laron Z. Skorecki K, Ausiello D. In: Cecil's Medicine. Mandl KD. Hypernatremia, hyponatremia, and hypoglycemia occasionally complicate dehydration. Molla AM, Normally, serum osmolarity controls moment-to-moment ADH release. All rights Reserved. Teach SJ, Dehydration can result from vomiting, diarrhea, not drinking enough fluids, or any combination of these conditions. Identify signs and symptoms of dehydration in pediatric patients. 4. The pathophysiology of dehydration is reviewed. 1,000 mL, plus 50 mL per kg for each kg between 11 and 20 kg, 40 mL, plus 2 mL per kg for each kg between 11 and 20 kg, 1,500 mL, plus 20 mL per kg for each kg over 20 kg, 60 mL, plus 1 mL per kg for each kg over 20 kg. Arch Dis Child. Replacement should be milliliter for milliliter in time intervals appropriate for the rapidity and extent of the loss. Vega RM, Pediatrics. Because sodium is restricted to the extracellular fluid space, the typical signs of dehydration are less pronounced in the setting of hypernatremia, and significant circulatory disturbance is not likely to be noted until dehydration reaches 10 percent. Clinical dehydration scales based on a combination of physical examination findings are the most specific and sensitive tools for accurately diagnosing dehydration in children and categorizing its severity. Recent literature suggests that hospitalized dehydrated children receiving 0.2% saline for maintenance fluid sometimes develop hyponatremia. Murphy KO. DeWalt DA, 2008;23(5):677–680. More complex calculations (eg, those using body surface area) are rarely required. DefinitionDefinition is defined as an excessive loss of body fluid & electrolytes. The traditional approach to calculating the composition of maintenance fluids was also based on the Holliday-Segar formula. 2004;114(5):1227–1234. Spandorfer PR, With hypotonic fluid replacement (eg, with plain water), serum sodium may normalize but can also decrease (hyponatremia). Stool electrolyte content and purging rates in diarrhea caused by rotavirus, enterotoxigenic. Baseline estimates are affected by fever (increasing by 12% for each degree > 37.8° C), hypothermia, and activity (eg, increased for hyperthyroidism or status epilepticus, decreased for coma). 2004;19(3):364]. dehydration and its treatments. Sampson A, Rahman O, The resuscitation phase should reduce moderate or severe dehydration to a deficit of about 8% body weight. Choose a single article, issue, or full-access subscription. Dixit S, Although practice variation still exists in choosing appropriate maintenance IV fluids, all clinicians agree the important point is to closely monitor dehydrated patients receiving IV fluids, which includes monitoring of serum electrolyte levels.
