Management of Pediatric Dehydration - Causes, Clinical Features, and Treatment.

Introduction:

Dehydration among children is challenging to manage, especially in settings where resources are fewer. Along with body fluids, different degrees of electrolytes are lost during dehydration. Infant mortality is most often caused by dehydration, which is caused by severe diarrheal diseases.

What Is Pediatric Dehydration?

Dehydration is the most common reason for morbidity and mortality among children. It was estimated that 14 to 30 percent of deaths occur due to dehydration and diarrheal diseases in the world. Children and infants were found to contain a higher percentage of total body water (TBW) when compared to adults. They contain 65 to 80 percent of TBW. Children are easily affected by dehydration because they cannot effectively communicate their thirst to caregivers, cannot access fluids easily, have increased metabolic rates, and have higher evaporative losses.

What Are the Objectives of Pediatric Dehydration?

The objectives of pediatric dehydration include:

• Recognizing signs and symptoms of dehydration and causes among children.

• To distinguish between isonatremic, hyponatremic, and hypernatremic dehydration among children.

• Implementation of a treatment plan among children with dehydration.

• Collaborating with team members to identify, evaluate, treat, and monitor children with dehydration.

What Are the Causes of Dehydration Among Children?

Dehydration is caused by increased fluid loss, decreased fluid intake, or because of both reasons.

Increased fluid loss occurs for various reasons, such as vomiting, diarrhea, or both. These may be caused by gastroenteritis. Other reasons include diabetic ketoacidosis (a diabetic complication caused by increased production of blood acids called ketones), increased sweating, burns, and fluid loss into the intestinal lumen in the case of bowel obstruction or ileus.

Decreased fluid intake occurs when children suffer from pharyngitis (sore throat or inflammation of the pharynx) and certain serious diseases. It can also be problematic for vomiting, fever, or tachypnea. This condition may occur due to neglect.

What Is the Pathophysiology of Dehydration?

Dehydration results from decreased TBW in both intracellular and extracellular fluids. TBW contains two-thirds of intracellular water and one-third of extracellular water. TBW is found to be higher among infants and children when compared to adults. Dehydration is considered total water depletion, and volume depletion is decreased circulatory volume. Volume depletion can be observed in the case of burns, acute blood loss, sepsis, and anaphylaxis.

What Are the Symptoms of Dehydration Among Children?

The symptoms among infants include:

• A soft spot on their head looks sunken.

• Eyes appear to be sunken.

• Infants do not exhibit tears when they cry.

• Mouth exhibits dryness.

• Infants do not produce much urine.

• Infants exhibit reduced alertness and are found to be underactive.

Moderate and severe dehydration may cause rapid heartbeat and lightheadedness. In cases of severe dehydration, children may feel sleepy or lethargic. They may exhibit bluish discoloration of the skin (cyanosis) and can breathe rapidly. Dehydration may lead to variations of salts in the blood. In severe cases, children may exhibit seizures, coma, or brain damage. Severe dehydration may sometimes be fatal.

How to Diagnose Dehydration Among Children?

Dehydration can be diagnosed by:

• History and Examination by the Doctor: Based on children's symptoms, like feeling thirsty, the doctor will examine them for any weight loss. Loss of weight in a few days indicates dehydration. The amount of weight loss helps you know the severity of dehydration.

• Blood Test: This test determines electrolyte levels and kidney function.

• Urine Test: This test is done to know the causes of dehydration.

These tests help diagnose and predict the amount of fluid replacement required.

How to Treat Dehydration Among Children?

Dehydration can be managed by drinking water. Oral rehydration sachets can also be used. The powder should be mixed with water and consumed. Lost fluids should be replaced. Fluids containing electrolytes like sodium and chloride can treat dehydration.

Children should be treated as follows:

• The doctor’s advice is to be followed strictly.

• Children younger than two years should not be given over-the-counter medications (OTC) for diarrhea unless prescribed by the doctor.

• Children should be given unsweetened fluids.

• Children should continue to breastfeed normally.

• Electrolyte solutions should be given according to the doctor's instructions.

• The food and fluids should be given slowly.

• The child must be put to rest.

If the child has only diarrhea, they should be given a lot of fluids less often. If children are having diarrhea and vomiting, they should be given fluids containing electrolytes. These fluids should be given frequently. If diarrhea increases with this treatment, the child should be hospitalized, and fluids should be given intravenously. Infants who cannot take fluids should be given intravenously or through a thin plastic tube passed through the nose.

DNS is a combination of two medicines. These include dextrose and sodium chloride. It is a purified salt solution and is used in dehydration treatment.

What Are the Differential Diagnosis of Pediatric Dehydration?

A healthcare provider must distinguish the causes of dehydration among children before the diagnosis. Dehydration is caused by fluid loss or insufficient consumption of oral fluids. It may also specify other medical conditions that are located beneath, like viral or bacterial gastroenteritis, urinary tract infections, sepsis, or shock. These underlying medical conditions were thought to cause electrolyte imbalances. These conditions are to be identified and treated to resolve dehydration.

If a person is affected by metabolic disorders like diabetes insipidus, ketoacidosis from diabetes mellitus, and congenital adrenal hyperplasia with impaired water and electrolyte imbalances may suffer from dehydration. Structural defects like pyloric stenosis or malrotation with volvulus can obstruct gastrointestinal function and may cause fluid loss and as a consequence may result in dehydration.

What Is the Prognosis of Pediatric Dehydration?

The prognosis of dehydration depends on many factors. These include limited facilities for clean water and healthcare, sanitation, and immunization. In certain areas with fewer healthcare facilities, severe dehydration may result in complications like electrolyte imbalances, organ failure, and even death. Continual dehydration with gastrointestinal infections may result in long-term poor health and retarded growth among children. These factors should be identified and tackled for a better prognosis of pediatric dehydration.

How Can One Prevent Dehydration?

Dehydration can be prevented in the following ways:

These include:

• Parents should always give their children an extra fluid or oral rehydration solution if they are sick.

• Parents should give a minimal amount of oral rehydration solution.

• Children need to drink water more frequently during hot weather.

• Children who play sports and are physically active should be given more water regularly.

• Sodas, cold drinks, and flavored gelatin, considered sugary drinks, must be avoided.

Conclusion:

Dehydration among children occurs when body fluids are lost for specific reasons like diarrhea or vomiting. It should be recognized and treated as early as possible. This condition may become fatal if not managed on time. Hence, it is essential to know about dehydration, its causes, symptoms, management, differential diagnosis, prognosis, and prevention. Knowing in detail about the condition helps identify it in the early stage and can be effectively treated. Preventive measures help prevent the condition from occurring.
