Dehydration is a common condition that can often be treated by drinking enough fluids to replenish your body. However, severe dehydration can be life-threatening and requires immediate medical attention. Treatment for dehydration in a hospital setting typically involves administering intravenous (IV) fluids to quickly restore fluid and electrolyte balance in the body. This is especially important for vulnerable groups, including infants, children, and older adults, who are at a higher risk of severe dehydration and its associated complications.

What You'll Learn
Intravenous rehydration
IV rehydration is commonly used in paediatric patients, particularly for dehydration due to diarrhoea, and is also employed in adults for a broader range of indications, such as fever, drug intoxication, and hypercalcemia. The prevalence of IV rehydration therapy in hospitals varies, with rates ranging from 4.5% to 100% in paediatric patients and 1.5% to 100% in adults.
The type, amount, and infusion rate of IV rehydration are tailored to each patient's needs, taking into account factors such as body composition, dehydration level, cardiac output status, and clinical parameters like daily urine output or blood pressure. While IV rehydration is generally safe and effective, it carries a few small risks, including air embolism, vein collapse, and fluid overload, which can lead to complications such as interstitial oedema and acute pulmonary oedema.
IV rehydration is often necessary when dehydration is severe enough to cause hypovolemic shock, characterised by symptoms such as pale, cool, and clammy skin, rapid heartbeat, and shallow breathing. In such cases, emergency medical treatment is required, as severe dehydration can lead to kidney damage, brain damage, and even death if left untreated.
IV rehydration is a valuable tool in correcting fluid imbalances and restoring fluid balance, especially in vulnerable populations like children and older adults, who are at higher risk for severe dehydration and its associated complications.

Oral rehydration solutions
The World Health Organization (WHO) recommends giving children under two a quarter to a half cup of fluid following each loose bowel movement and older children a half to a full cup. For older children and adults, the recommended intake is 200-400 mL of solution after every loose movement, taken in frequent sips from a cup. If the person vomits, caregivers should wait 5-10 minutes before resuming the administration of ORS.
ORS can also be given through a nasogastric tube, especially in cases where the child cannot or will not drink the solution orally. The WHO recommends that children who are breastfed should continue breastfeeding throughout the administration of ORS. Additionally, supplemental zinc (10-20 mg daily) is recommended for 10-14 days to reduce the severity and duration of the illness and lower the risk of recurrent illness in the following 2-3 months.
In cases of severe dehydration, professional medical help should be sought immediately, and intravenous rehydration should be administered as soon as possible to rapidly replenish fluid volume in the body.

Dialysis
Dehydration is a common condition that can be addressed by drinking enough fluids to replenish your body. However, severe dehydration can be life-threatening and requires immediate medical attention, often in a hospital setting. In cases of severe dehydration, intravenous (IV) rehydration is typically administered in a hospital emergency room.
There are two types of dialysis: hemodialysis and peritoneal dialysis. Hemodialysis utilizes a machine to clean the blood and then returns the filtered blood to the body. Peritoneal dialysis, on the other hand, involves filling the abdomen with a dialysate solution to facilitate waste and fluid removal. While dialysis can be a frequent and time-consuming process, it is crucial for those with kidney failure to prevent the dangerous buildup of toxins in the blood.
For those undergoing dialysis, maintaining proper hydration is essential. Dehydration during dialysis can occur, and patients are advised to monitor their fluid intake carefully and consult their healthcare team for guidance. Dialysis patients should aim for a daily fluid intake of 6-8 cups or glasses, as recommended by the NHS and supported by European guidelines. This helps the kidneys flush out waste products and lowers the risk of developing chronic kidney disease.
In summary, dialysis is a treatment primarily used for individuals with kidney dysfunction or failure, and it plays a vital role in managing severe dehydration when kidney function is impaired. While dialysis can be a challenging and ongoing process, it is often necessary to maintain health and prevent further complications.

Treating the cause of dehydration
Dehydration occurs when the body loses more fluid than is taken in, and it can be serious if not treated promptly. The treatment for dehydration depends on the severity of the condition. Mild dehydration can be treated at home by drinking plenty of fluids, while moderate to severe dehydration may require medical intervention, such as intravenous (IV) fluids in a hospital setting.
For individuals experiencing vomiting or diarrhea, it is crucial to prioritize oral rehydration solutions (ORS) that contain the right balance of water, sugars, and salts. These solutions help replenish lost fluids and electrolytes, supporting the body's rehydration process. In cases where dehydration is caused by excessive sweating, such as in athletes or individuals working in hot environments, it is essential to increase fluid intake and consider electrolyte-rich sports drinks to replace lost minerals.
Additionally, certain medications can contribute to dehydration by increasing fluid loss through urination. If dehydration is suspected to be related to medication use, consulting a healthcare professional is vital. They may advise adjusting the dosage or provide guidance on managing fluid intake to minimize the risk of dehydration.
For older adults, the risk of dehydration may be heightened due to a decrease in the body's fluid reserve and a reduced thirst drive. Therefore, it is essential to encourage adequate fluid intake and monitor for signs of dehydration, especially during hot weather or periods of illness. Similarly, infants and young children are at higher risk of dehydration due to their lower body weight and higher fluid requirements relative to their size. Caretakers should be vigilant in offering fluids and seeking medical attention if dehydration is suspected.
In summary, treating the cause of dehydration involves identifying and addressing the underlying factors contributing to fluid loss. This may include managing vomiting or diarrhea, increasing fluid intake during illness or hot weather, adjusting medications that affect fluid balance, and being vigilant with fluid intake for at-risk groups such as older adults, infants, and young children. By addressing the specific cause of dehydration, individuals can effectively restore fluid balance and prevent further complications.

Preventing dehydration
Dehydration is a common condition that arises when the body loses more fluid than is taken in. It can be prevented by drinking fluids regularly, even when one is not thirsty. Water, diluted squash, fruit juice, sports drinks, and oral rehydration solutions are all effective in preventing dehydration. It is important to increase fluid intake during hot weather or when exercising, and to pay close attention to the fluid intake of children and older adults, as they are at a higher risk of dehydration.
For those with vomiting or diarrhea, it is crucial to drink plenty of fluids to compensate for the loss of body fluids. In cases of mild dehydration, oral rehydration solutions can be made at home by mixing salt, sugar, and water, or by mixing fruit juice, water, and a pinch of salt and freezing it into ice cubes or ice pops. These solutions are especially beneficial for children, as water alone can cause a drop in sodium levels.
Additionally, certain foods can contribute to fluid intake, with about 20% of daily fluid coming from food sources. Fruits such as watermelon, strawberries, oranges, and grapes, as well as vegetables like lettuce, cucumber, and zucchini, are high in water content and can aid in hydration. Salty snacks can also help replace lost electrolytes, but it is important to accompany them with water or an electrolyte solution to avoid increased thirst.
By staying vigilant about fluid intake, being aware of the risk factors, and taking proactive measures to prevent dehydration, many cases of dehydration can be avoided, reducing the need for hospital treatment.
