Brisbane Intravenous Therapy

Intravenous (IV) Fluid Therapy 


IV fluids are specially formulated liquids that are infused through a vein into your body to treat dehydration. They are used in people of all ages who are sick, dehydrated from gastroenteritis, morning sickness or exercise or heat.  Intravenous rehydration is a simple, safe and common procedure with a low risk of complications.


What are IV fluids?


IV fluids are liquids injected into a person’s veins through an IV (intravenous) tube. They prevent or treat dehydration and electrolyte imbalances.



Why are intravenous fluids used?


Water is essential to every cell in our bodies. In fact, our bodies are made up of about 60% water. When you don’t have enough water in your body, that’s called dehydration. A person needs IV fluids when they become dangerously dehydrated.


Serious dehydration may occur when you:

  • Are sick (vomiting and diarrhoea) from gastroenteritis or vomiting from severe morning sickness (also known as Hyperemesis gravidarum).
  • Exercise too much or spend too much time in the heat without drinking enough.



What are the effects of dehydration?


When you are dehydrated, it can affect:

  • Balance of important minerals (electrolytes) in the body.
  • Cognitive (mental) performance.
  • Energy level.
  • Gastrointestinal function (your ability to digest food and create pee and poop).
  • Headache frequency and intensity.
  • Many organs, including the kidneys, heart and brain.


Signs of severe dehydration include:

  • Dizziness
  • Dry lips and tongue.
  • Dry, wrinkly or blotchy skin.
  • Fatigue (feeling tired).
  • Fast breathing.
  • Hands and feet that are cool to the touch or blotchy looking.
  • Less pee than usual (fewer than four times per day).

Procedure Details


There are different kinds of IV fluids. Your healthcare provider will decide which type is right for you, depending on why you need them.


What happens during rehydration with IV fluids?


If you need IV fluids, your healthcare provider at Top Health Doctors will:

  • Decide the type of IV fluid you need (usually normal saline).
  • Determine the amount of fluid you need and how quickly. This is based on many factors, including your weight, age and medical conditions.
  • Disinfect (clean) the skin where the IV will go, usually on the inside of the elbow or on top of the hand.
  • Tie an elastic band (tourniquet) around your arm to make blood fill the veins.
  • Examine the veins to find the exact insertion site.
  • Slide a sterile needle into the vein, which may pinch. The needle will have a small plastic tube at the other end.
  • Remove the tourniquet.
  • Place a small plastic attachment onto the tube.
  • Test the tube to make sure a little bit of fluid can go in.
  • Tape the IV needle to your arm so that it stays in place.
  • Attach the small tube to a longer tube, and then attach it to a bag of fluids.
  • Hang the bag from a hook on a tall stand (called an IV stand).
  • Check your IV line regularly and monitor the amount of fluid entering your body.



What happens after IV fluids?


IV fluids may make you feel better very quickly. But your healthcare providers will determine when you can stop receiving intravenous fluids.




What is the recovery time after receiving IV fluids?


Many people don’t need recovery time or have any restrictions after receiving IV fluids.

However, you may need other treatments or additional rest depending on the reason you needed rehydration in the first place. For example, if you had vomiting or diarrhea due to infection, you might need to take medicines afterward.

Ask your healthcare provider about your recovery and restrictions.


In summary


IV fluids are specially formulated liquids that are infused through a vein into you to prevent or treat dehydration. Intravenous rehydration is a simple and safe procedure used in people who are sick, dehydrated from gastroenteritis, severe morning sickness or from exercise with significant heat exposure.
