Dehydration is a common condition that can be easily addressed by drinking enough fluids. However, severe dehydration is a medical emergency that requires immediate treatment in a hospital setting. Severe dehydration occurs when the body loses more fluids than it takes in, leading to a drop in fluid levels that affects organ function and bodily processes. Treatment for severe dehydration in a hospital typically involves intravenous (IV) fluids, which are administered through a vein to speed up recovery. In addition to rehydration, underlying causes of dehydration, such as diabetes or bacterial gastroenteritis, are also addressed as part of the treatment process.

What You'll Learn
Intravenous fluids
Intravenous (IV) fluids are liquids injected into a person's veins through an IV tube to prevent or treat dehydration. IV rehydration is a common, simple, and safe procedure that can make a patient feel better quickly and help save their life if they are seriously ill. It is often used to treat children, who are more likely to become dangerously dehydrated when they are ill.
IV fluids are used when a person is dangerously dehydrated, which can be caused by sickness (vomiting and diarrhea), exercise without drinking enough fluids, serious injury or burns, or surgery. Dehydration can also be caused by spending too much time in the heat without drinking enough, which can also lead to heat injuries. Severe dehydration can cause weakness or confusion, and in extreme cases, it can lead to brain damage and even death.
The decision to administer IV fluids is made by healthcare providers, who will also determine when to stop treatment. The optimal amount and composition of IV fluids to be administered, as well as the rate at which they are given, must be based on a careful assessment of the patient's individual needs. In cases of IV fluid resuscitation, crystalloids containing sodium in the range of 130-154 mmol/l are used, with a bolus of 500 ml over less than 15 minutes.
IV rehydration carries a few small risks, such as air embolism, vein collapse, and fluid overload, but these are generally outweighed by the benefits.

Blood and urine tests
Blood tests are performed to check for several critical indicators. Firstly, they assess electrolyte levels, particularly sodium and potassium, which are essential for maintaining bodily functions. Electrolyte imbalances can lead to serious complications, so restoring these levels is a priority. Secondly, blood tests evaluate kidney function. The kidneys play a vital role in fluid balance and electrolyte regulation, so their proper functioning is crucial in treating dehydration.
Urine tests, or urinalysis, are another essential tool. They can indicate the presence and severity of dehydration. By analysing urine composition, healthcare professionals can determine the extent of dehydration and make informed decisions about fluid replacement therapy. Urine tests can also detect bladder infections, which may be a contributing factor or a complication of dehydration.
The results of these tests help medical professionals determine the severity of dehydration and tailor the treatment plan accordingly. In cases of severe dehydration, intravenous (IV) fluid administration is often necessary to rapidly replenish fluid levels and prevent further complications. This approach is especially critical in vulnerable populations, such as children, older adults, and individuals with pre-existing health conditions, who are at higher risk of severe dehydration and its associated health risks.
It is important to note that treating dehydration involves more than just fluid replacement. Addressing the underlying causes and correcting electrolyte imbalances are equally vital components of the treatment process. Therefore, blood and urine tests play a pivotal role in guiding the comprehensive management of severe dehydration in a hospital setting.

Oral rehydration solutions
Oral rehydration therapy (ORT), also known as Oral Rehydration Solution, was first introduced in the 1940s but came into common use in the 1960s. It is considered the gold standard for treating fluid loss resulting from acute diarrhoea. ORT is particularly useful in resource-limited settings, such as refugee camps, health clinics, and developing countries. It is also recommended for infants and children who are dehydrated from diarrhoea, vomiting, or fever.
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. Older children and adults should take frequent sips, with a recommended intake of 200-400 ml of solution after every loose movement. If vomiting occurs, it is recommended to wait 5-10 minutes before resuming ORS administration.
ORT has been shown to be effective in reducing morbidity and mortality associated with dehydration. It is estimated to decrease the risk of death from diarrhoea by up to 93%. Case studies have also demonstrated a link between increased ORS use and reduced mortality. Additionally, ORT has been associated with shorter hospital stays and increased patient satisfaction compared to IV rehydration therapy.
However, it is important to note that ORT is suitable for people with mild to moderate dehydration. For severe dehydration, professional medical help should be sought immediately, and intravenous rehydration is typically required to rapidly replenish fluid volume.

Treating the underlying cause
Dehydration is a common condition that can be easily addressed by drinking enough fluids to replenish your body. However, severe dehydration is a medical emergency that requires immediate treatment with intravenous (IV) fluids in a hospital setting. This is particularly important for infants, young children, older adults, and those who are pregnant, as they are at higher risk of severe dehydration and serious health complications.
In some cases, severe dehydration can be caused by excessive sweating due to extreme temperatures or spending too much time in a sauna. In these instances, treating the underlying cause involves helping the individual cool down and avoid further fluid loss. This may include moving them to a cooler environment, providing them with cool drinks, and helping them reduce their physical activity.
For individuals with severe dehydration caused by vomiting or diarrhoea, it is essential to address these underlying issues. Medications such as loperamide (Imodium) for diarrhoea and ondansetron (Zofran) for nausea can be administered to help manage these symptoms. Additionally, oral rehydration solutions like Pedialyte or Hydralyte can help replace lost fluids and electrolytes, aiding in the treatment of the underlying cause of dehydration.
Underlying causes of severe dehydration can vary greatly, and in some cases, individuals may have multiple contributing factors. It is important to seek medical attention and undergo a thorough examination, including blood tests and urinalysis, to determine the specific causes and tailor the treatment plan accordingly.

Monitoring health complications
Severe dehydration is a life-threatening medical emergency that requires immediate treatment. It can lead to organ damage and other health complications, and in extreme cases, it can even result in brain damage and death. Therefore, monitoring health complications is crucial during treatment.
Upon arrival at the hospital, a patient's vitals will be checked, and their medical history will be analysed to identify the immediate and underlying causes of dehydration. Blood tests will be conducted to check electrolyte levels, particularly sodium and potassium, and kidney function. Urine tests can also be performed to assess the severity of dehydration and check for bladder infections. These initial tests provide a baseline for monitoring the patient's health status and the effectiveness of the treatment.
The primary treatment for severe dehydration is the administration of intravenous (IV) fluids to quickly replenish lost fluids and electrolytes. Monitoring during this process is crucial to ensure the patient's body can handle the rapid fluid intake. Healthcare professionals will closely observe the patient's vital signs, such as heart rate, blood pressure, and respiratory rate, to ensure stability and detect any adverse reactions.
In addition to vital signs, healthcare providers will monitor the patient's level of consciousness, mental confusion, and alertness. Dehydration can cause weakness and confusion, so it is important to assess the patient's mental status during treatment. Additionally, the patient's skin condition will be monitored. Skin turgor, or skin elasticity, is a late sign of dehydration, and an improvement in skin turgor indicates effective rehydration.
For patients with severe dehydration due to underlying health conditions, such as diabetes or bacterial gastroenteritis, monitoring of specific health complications related to these conditions is essential. For example, in patients with diabetes, blood sugar levels and the presence of uncontrolled diabetes-related symptoms, such as excessive urination, will be monitored. In cases of bacterial gastroenteritis, the patient's condition will be closely watched for any deterioration or improvement, and appropriate medications will be administered.
