You are currently viewing IV Fluids for Dehydration: All that you need to know

The specially formulated infusion fluids are injected into the vein to treat dehydration. The IV infusion therapy is used by people of all ages, either dehydrated, sick, injured, or undergoing surgery. This is a simple and safe method of maintaining body fluids with the least complications.

How Do IV Fluids Help Dehydration?

To relieve the symptoms of severe or moderate dehydration, IV therapies are recognized as the best dehydration treatments. In this process of IV rehydration, vitamins, nutrients, and fluids are injected into the bloodstream. Depending upon your symptoms and severity of the dehydration in your body, the type of fluid and its amount may vary during the rehydration process. Moreover, the choice of the fluid to be injected into your bloodstream is also determined by your pre-existing medical conditions and age. IV fluids injected through the therapy stay in your body until all the contents have been metabolized.

What Causes Dehydration?

Dehydration occurs when you take less than the required fluid by drinking very little water throughout the day. Your body uses water lost while sweating, breathing, urinating, and through tears and saliva. If you don’t consume enough water required by your body, your body will soon become deficient in fluid and nutrients. You can recover the lost water and nutrients only through water and a proper diet containing surplus water that may hydrate your body and replenish its fluids.

Sometimes, you face even severe dehydration when suffering from conditions like

  • While experiencing excessive sweating
  • Having fever or diarrhea
  • in case of vomiting within the 24 hours
  • Urinating more than usual.

Sometimes you lose your body water and fluids because you don’t realize that you are dehydrated, like when you are busy, not feeling thirsty, or having a sore throat that prevents you from consuming water.

Common Dehydration Side Effects

Exsiccosis, also known as dehydration, is a condition marked by a drop in water level in the body, which results in hypertonic and hypernatremic symptoms. It occurs when fluid in your body is not enough for all your body organs’ normal and proper functioning.

Benefits of IV Fluids

You might have been thinking about the components of the IV hydration fluid. It is a saline solution that contains water, electrolytes, and sodium chloride. It functions to restore your body’s natural fluids and replenish the hydration fluid. The fluid injected into the bloodstream passes through the digestive system and rehydrates the body faster.
Once your body gets dehydrated, you may feel many positive changes that include:

  • Enhanced clarity and mental concentration
  • Clearer skin
  • Improved cardiovascular health
  • Cushioning of your joints and muscles

These perks become especially important if you have recently recovered from some severe medical condition or are experiencing cold symptoms. Because, in these circumstances, your body would be more deficient in nutrients, and you may face severe dehydration symptoms, IV infusion therapy can help you recover fast.

Types of IV fluids

Intravenous fluids are mostly administered to patients brought to the hospital due to severe dehydration. Many intravenous therapy fluids are used as maintenance fluids and IV boluses. The types of fluids to be injected depend upon the patient’s condition.

1. Crystalloid solutions

Crystalloid solutions are the most commonly infused IV fluids containing small molecules that can easily diffuse from the bloodstream into the tissues and cells. Examples of crystalloid solutions include saline, the solution of salt in water, and Dextrose, which is sugar in water. Another example is lactated Ringer’s solution, which contains chloride, potassium, sodium, calcium, and lactate. Lactated Ringer’s are used for aggressive fluid replacement.

2. Colloids

Colloids are large molecules that stay in the blood vessels and can not pass through the cell membrane. Examples of colloids include hetastarch and albumin.

Maintenance Fluids vs. IV Bolus

Maintenance Fluids:

Maintenance fluids are the IV fluids that run slowly to overcome the expected fluid loss and decrease the PO intake. People who cannot take fluids by mouth are recommended IV maintenance fluids to minimize the ongoing fluid loss with many medical conditions.

  • People suffering from fever require maintenance fluids due to water losses caused by increased metabolism and sweating.
  • The people suffering from diarrhea and vomiting also need increased fluids to overcome the water losses.
  • The same is for people who face significant drainage.
  • Patients with pancreatitis and burns also require large volumes of fluid.
  • People with dehydration, acute renal failure, and mild hyponatremia require maintenance fluid for maintaining renal function and sodium levels.

IV Bolus:

IV boluses are the fluids administered in extreme medical illness to patients in ER or ICU with unstable blood pressure. IV boluses help them support hypotension and maintain blood pressure.

  • The patients initially brought to ER are suggested to take almost a liter of IV bolus. In contrast, people with extreme dehydration, migraine, sepsis, shock, and abdominal pain are suggested to take 1-3 liters of IV fluid.
  • For smooth bolus flow, it is suggested to hang the bolus and wide open the clamp. The patient should keep their arms straight while getting the fluid administered into their bloodstream.

Indications for Intravenous Fluids

In addition to being used for hydrating a dehydrated person, IV fluids are commonly used in healthcare institutions for people suffering from diarrhea, nausea, vomiting, abdominal pain, bleeding, headache, acute kidney injury, and maintaining blood pressure for people suffering from sepsis and hypotension.
Moreover, the people who cannot maintain the required daily uptake of liquid use intravenous fluids as maintenance fluids throughout the day.

Pros & Cons of IV Fluids for Dehydration in Dubai

Medical practitioners extensively use IV fluid therapies to treat many medical conditions as this is an efficient way to replace the replenished fluid.

  • Due to the rapid performance of IV fluids, they are considered best for someone struggling with a deficiency of electrolytes in the body fluids.
  • These fluids provide exactly what the body needs for managing dehydration.
  • The different formulations of fluids for different ailments help provide the patient with customized solutions for addressing the fluid imbalance, fluid deficit, and electrolyte composition by targeting the root cause.


Despite the amazing benefits of IV fluid therapy, it comes with certain drawbacks.

  • Intravenous fluid therapy is usually an inpatient procedure. Hence you might be required to pass through a lot of paperwork, and you might be required to stay in the pediatric care center or the hospital for long.
  • Moreover, you won’t get discharged unless your nurse or doctor permits you.
  • In addition, rehydration through IV infusion might be painful, especially for people who have a phobia with needles. You might face a hard time if you are afraid of needles and injections because the needle stays in your arm throughout the process, which results in discomfort.
  • The vein may collapse in case of a needle injected into it for an extended period when the patient suffers from extreme dehydration. Vein collapse happens when long-term and repeated treatment is required. This condition is common among children. However, it is not life-threatening. The nurse needs to re-inject the IV fluid in some other vein as an alternative.
  • Moreover, more movement during the IV infusion therapy may dislodge the needle in the vein and cause infiltration. This happens when the needle moves and causes the fluid to move outside the vein, which results in a stinging sensation and causes bruising. To improve such conditions, the nurse or doctor needs to reinsert the vein perfectly at a place in the vein.
