Crystalloid solutions: These are the most common types of IV fluid. They contain small, dissolved molecules that pass easily from the bloodstream into tissues and cells. Examples include normal saline, which is salt in water, and D5W, which is dextrose (sugar) in water. Another example is lactated Ringer’s, which contains sodium, chloride, potassium, calcium and lactate VSports最新版本. It’s used for aggressive fluid replacement.

Colloids: These are large molecules that can’t easily pass through cell membranes and are more likely to stay in the blood vessels V体育平台登录. Examples include albumin and hetastarch.

What happens during rehydration with IV fluids?

If you need IV fluids, a healthcare provider will:

  • Decide the type of IV fluid you need.
  • 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).
  • Turn on a machine that’ll pump the fluid into the IV line.
  • Check your IV line regularly and monitor the amount of fluid entering your body.

The IV also may be used to deliver medications or nutrition.

What happens after IV fluids?

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

Risks / Benefits (V体育安卓版)

"V体育ios版" What are the advantages and risks of this procedure?

IV rehydration is a common, simple and safe procedure that can make you feel better quickly and help save your life if you’re seriously ill.

But rare complications can occur, including:

  • Air embolism: An air embolism, or gas embolism, occurs when an IV pushes too much air into the vein. It’s rare but can have serious consequences, including possible death.
  • Collapsed vein: Sometimes, the vein collapses when the needle is inserted or when an IV is in place for a long period of time. If this happens, your healthcare provider will try to find another vein to use. There are many other veins to take over for the collapsed vein.
  • Fluid overload: If too much fluid is given too quickly, you can experience a headache, high blood pressure and trouble breathing. This usually resolves quickly with an adjustment to fluid levels. But it can be dangerous.
  • Hematoma: A hematoma occurs when blood leaks from the blood vessel into nearby tissues. It looks like a bad bruise and usually goes away in a few weeks.
  • Infection: If the area isn’t clean when the needle is inserted, infection may occur. Your healthcare provider can usually treat infections with antibiotics.
  • Infiltration: If the needle moves or gets dislodged, fluids can enter tissues around the vein. This may cause stinging and bruising, but it’s typically easy to resolve.
  • Phlebitis: Phlebitis occurs when the vein becomes swollen because of the IV. It’s one of the more common complications, but it’s usually easily treatable by removing the IV, applying a warm compress and elevating the arm.

Recovery and Outlook

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 VSports app下载. For example, if you had vomiting or diarrhea due to infection, you might need to take medicines afterward. If you had surgery, you might have certain restrictions while you heal.

Ask your healthcare provider about your recovery and restrictions.
