Emergency Hydration: Hospital Treatment For Dehydration

Dehydration is a condition in which the body loses more fluids than it takes in, causing it to not have enough water to function normally. It can be caused by various factors such as diarrhoea, vomiting, excessive sweating, fever, or inadequate fluid intake. While mild dehydration can often be treated by increasing fluid intake, moderate to severe dehydration requires medical attention and is typically treated in hospitals with intravenous (IV) fluids. This involves administering salts and fluids through a vein to speed up the recovery process. In this paragraph, we will explore how dehydration is treated in a hospital setting, focusing on the procedures and interventions used to manage this condition.

Intravenous fluids for severe dehydration

Intravenous (IV) rehydration is a procedure used to treat moderate to severe dehydration when oral rehydration is insufficient. It involves inserting a thin plastic tube with a needle, known as an IV line, into a vein in the patient's arm. The other end of the line is connected to a bag of fluids, typically hung above the patient's head.

The IV solution consists of sterile water with small amounts of salt (sodium chloride) or sugar (dextrose, glucose, or levulose). One of the most commonly used IV fluids is 0.9% normal saline, which contains 0.9% sodium chloride in sterile water. The type of fluid solution is determined by medical professionals based on the patient's age, existing medical conditions, and the severity of their dehydration.

The amount and rate of IV fluid administration vary depending on the patient's body composition, dehydration level, and cardiac output status, as well as clinical and hemodynamic parameters such as daily urine output or blood pressure. The patient's vital signs, medical history, and underlying causes are also considered in determining the appropriate treatment plan.

IV rehydration therapy is a safe and effective way to supply fluids directly into the patient's intravascular fluid compartment. However, there is a small risk of infection at the injection site, and prolonged IV insertion can cause vein collapse. Therefore, medical professionals closely monitor the patient's IV line to ensure they receive the right amount of fluids and address any potential complications.

In some cases, IV rehydration is combined with other treatments targeting the underlying causes of dehydration. For example, patients with hyperglycemia from diabetes may receive treatment for elevated blood sugar levels, or those with bacterial gastroenteritis may be treated for the infection. Additionally, medication management and dietary and fluid intake advice are often provided as part of a comprehensive approach to treating dehydration.

Oral rehydration sachets for mild dehydration

Dehydration is a condition in which a person loses so much body fluid that their body can’t function normally. It can be caused by diarrhoea, vomiting, fever, excessive sweating, or inadequate fluid intake. Severe dehydration can be life-threatening and requires immediate medical attention, often in the form of intravenous (IV) rehydration.

Mild dehydration, on the other hand, can usually be treated at home by drinking more fluids, such as water or clear broth. Oral rehydration therapy (ORT) is a type of fluid replacement therapy that can be used to treat mild to moderate dehydration, especially when it is due to diarrhoea. ORT involves drinking water with modest amounts of sugar and salts, specifically sodium and potassium. Oral rehydration sachets are powders that are mixed with water to form an oral rehydration solution (ORS). ORS is designed to optimise the absorption of fluid in the intestines, helping to quickly replenish fluids. It is often used to treat dehydration due to diarrhoea or vomiting and can be purchased over the counter or with a prescription.

The World Health Organization and UNICEF have used ORS to treat dehydration due to diarrhoea, and it is commonly used in countries with limited access to clean water or other hydration options. ORT is less invasive than intravenous fluid replacement and has played a significant role in reducing deaths due to diarrhoea, especially in children. According to 2018 research, oral rehydration therapy has prevented 54 million deaths due to diarrhoea since 2007 and has reduced diarrhoea-related deaths in children by two-thirds since 1980.

Oral rehydration sachets are typically well-tolerated and safe for children. However, it is important to follow the instructions provided and prepare the solution correctly. If the solution is not prepared or used correctly, it can lead to salt toxicity or hypernatremia. Additionally, oral rehydration therapy should be discontinued if vomiting occurs despite proper administration, if signs of dehydration worsen, or if there is evidence of intestinal blockage. In these cases, intravenous rehydration may be required.

Sports drinks to restore electrolytes

Dehydration is a condition in which a person loses so much body fluid that their body can’t function normally. It can be caused by a variety of factors, such as excessive sweating, fever, diarrhoea, vomiting, or not drinking enough water. Severe dehydration can be life-threatening and requires immediate medical attention, often in the form of intravenous (IV) fluid administration in a hospital setting.

Sports drinks are one way to restore electrolytes and rehydrate the body. Electrolytes are minerals that conduct an electrical charge when mixed with water, and they play a crucial role in nerve signalling, pH balance, muscle contraction, and hydration. While water is typically the best way to stay hydrated, sports drinks can be beneficial in certain situations, especially for athletes.

Traditional sports drinks like Powerade and Gatorade have received some criticism for their high sugar content. However, it's important to note that these drinks are designed for athletes who are exercising intensely and burning through glucose (sugar) and electrolytes at a rapid pace. The sugar in these drinks also helps electrolytes, particularly sodium, get into the cells faster, which can be advantageous for athletes who need sustained performance over long periods.

For those who are not engaging in intense or prolonged exercise, there are low-calorie and low-sugar sports drink options available, such as Gatorade Fit. Additionally, coconut water-based sports drinks like Coco5 are becoming increasingly popular due to their natural electrolyte content, including potassium, calcium, and magnesium. Coconut water is also low in calories and fat, making it a healthier alternative to traditional sports drinks.

Another option for restoring electrolytes is to use electrolyte tablets or drops that can be added to any water bottle. These products typically have little to no sugar and are designed to be consumed throughout the day for all-day hydration. For those who prefer a do-it-yourself approach, it is also possible to make your own sports drink at home by combining fruit juices, salt (a source of sodium), and water.

Treat underlying causes, e.g. diarrhoea or vomiting

Dehydration is a condition in which a person loses so much body fluid that their body can’t function normally. It can be caused by diarrhoea or vomiting, which are symptoms of many different health conditions, such as gastroenteritis, food poisoning, migraines, and cancer treatments.

If you are experiencing dehydration due to diarrhoea, it is important to treat the underlying cause. Diarrhoea is typically caused by a virus that infects the gut, also known as gastroenteritis or the "stomach flu". It can also be caused by food poisoning, medications, and infections. If you have acute diarrhoea, which is watery diarrhoea that lasts one to two days, it will usually go away without treatment. However, if it persists for more than two days or is accompanied by other symptoms such as a fever or bloody stool, it is important to seek medical attention. Your doctor can help determine the underlying cause and provide appropriate treatment.

To manage diarrhoea at home, it is important to stay hydrated by drinking plenty of clear fluids or oral rehydration solutions. It is recommended to avoid fruit juice, cordial, sugary drinks, alcohol, and caffeine, as these can upset the stomach. Instead, opt for water, and try adding a wedge of lime or lemon to make it tastier. Eating bland foods, such as rice, pasta, and crackers, can also help manage diarrhoea.

If you are experiencing dehydration due to vomiting, treating the underlying cause is crucial. Vomiting is commonly caused by viral gastroenteritis, which is highly infectious and spread through contact with an infected person. Other causes of vomiting include food poisoning, migraines, motion sickness, and cancer treatments. In most cases, vomiting is not a sign of anything serious and tends to last only a day or two. However, if it is difficult to determine the cause of recurrent vomiting, your doctor may suggest investigations such as an endoscopy or a CT scan.

To manage vomiting at home, staying hydrated is crucial. Drink clear and/or ice-cold beverages in small, gradual amounts. Eating light, bland foods, such as saltine crackers or plain bread, can also help. It is important to avoid fried, greasy, or sweet foods, and to eat slowly and in smaller, more frequent meals. If needed, nausea medication can be used to treat vomiting, but it is important to consult with a healthcare provider first.

Monitor vital signs and medical history

Dehydration is a common condition that affects patients of all ages. It occurs when the body loses more fluids than it takes in, and can be caused by a variety of factors such as exercise, heat exposure, medications, illness, impaired access to water, fever, fluid loss or inadequate fluid intake. Severe dehydration can be life-threatening and requires immediate medical attention.

When a patient presents with dehydration, it is important to monitor their vital signs and medical history to determine the severity of dehydration and rule out any other underlying conditions. Vital signs that may indicate dehydration include hypotension, tachycardia, fever, and tachypnea. Hypotension, however, may not appear until significant dehydration is present, and tachycardia may be absent if the patient is on certain medications such as beta-blockers. Other physical examination findings that may be indicative of dehydration include dry mucosa, skin tenting, delayed capillary refill, and cracked lips.

In addition to the physical examination, a patient's medical history can provide valuable information in diagnosing dehydration. Factors such as exercise, heat exposure, medications, illness, access to water, fever, and fluid loss can all contribute to dehydration and should be considered during the evaluation. It is also important to note that dehydration can be a comorbidity with other conditions, particularly in older adults. Delirium, for example, is a common comorbidity in patients who are dehydrated, and it is important for healthcare providers to recognise and treat this concurrently.

Furthermore, laboratory tests can be used to confirm the diagnosis of dehydration and identify any associated complications. Blood tests can check for electrolyte levels, particularly sodium and potassium, as well as kidney function. Urinalysis can also help to determine the severity of dehydration and rule out any bladder infections.

By carefully monitoring the patient's vital signs and medical history, healthcare providers can effectively diagnose and treat dehydration, ensuring the patient's volume is restored and addressing any underlying causes to prevent recurrence.
