Neonatal Hypernatremic Dehydration.
Pediatric Annals
|May 9, 2019
Summary
Hypernatremic dehydration in newborns, often due to insufficient breast milk intake, is a serious condition. Early recognition and careful treatment are crucial to prevent complications like seizures and neurodevelopmental delays.
Area of Science:
- Neonatalogy
- Pediatric Endocrinology
- Public Health
Background:
- Hypernatremic dehydration in exclusively breast-fed neonates stems from a free water deficit due to inadequate fluid intake.
- This condition is frequently underrecognized in primary care due to potential underestimation of dehydration severity from fluid shifts.
Observation:
- Neonates of first-time mothers and those with significant early weight loss are at increased risk.
- Presentation typically occurs between 6 and 10 days of life.
- Serum sodium levels exceeding 160 mEq/L correlate with higher morbidity and mortality risks.
Findings:
- No established treatment guidelines exist, but expert consensus suggests a serum sodium reduction rate of 0.5 mEq/L per hour over 48 hours.
- Complications, most commonly seizures, often arise during incorrect correction of hypernatremia.
- Long-term follow-up studies indicate potential neurodevelopmental delays in affected neonates.
Implications:
- Highlights the need for improved diagnostic awareness and management protocols for hypernatremic dehydration in neonates.
- Emphasizes the importance of monitoring fluid balance and weight loss in the first week of life for breast-fed infants.
- Underscores the critical need for standardized treatment guidelines to minimize neurological complications and improve long-term outcomes.

149.1K
Overview
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
Synthesis of carbohydrates
Sugar molecules are covalently linked together by dehydration synthesis. During the reaction, the hydroxyl (-OH) group from...

02:35Acid-Catalyzed Dehydration of Alcohols to Alkenes
23.8K
In a dehydration reaction, a hydroxyl group in an alcohol is eliminated along with the hydrogen from an adjacent carbon. Here, the products are an alkene and a molecule of water. Dehydration of alcohols is generally achieved by heating in the presence of an acid catalyst. While the dehydration of primary alcohols requires high temperatures and acid concentrations, secondary and tertiary alcohols can lose a water molecule under relatively mild conditions.

01:14Dehydration of Aldols to Enals: Base-Catalyzed Aldol Condensation
6.9K
This lesson delves into the aldol condensation catalyzed by bases, where aldols undergo dehydration to enals. As shown in Figure 1, the β-hydroxy aldehyde formed in a base-catalyzed aldol addition reaction dehydrates on heating to yield an unsaturated carbonyl product, which is commonly referred to as an enal.

12.8K
Overview
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

121.8K
Overview
Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...
