Infusion therapy is when medication or fluids are administered through a needle or catheter. It’s a way of delivering medication that can’t be taken orally, or that need to be dispensed at a controlled pace.

In this article, we’ll take a closer look at what infusion therapy is, how it works, and the types of conditions it can treat.

Infusion therapy is when you receive medication through a needle or catheter, usuallyintravenously (IV). Other types of infusion therapy include:

Some drugs can’t be taken orally because they lose their effectiveness when exposed to your digestive system. Infusion therapy is an alternative when there’s no comparable oral therapy or when you’re unable to take oral medication.

化疗是许多类型的常见治疗方法cancer. While some chemotherapies are given orally, many must be administered through an IV. In some cases, chemotherapy drugs are injected into the spine or to a specific part of the body.

Infusion therapy allows for the delivery of chemotherapy drugs directly into your bloodstream. It also enables you to receive anti-nausea and other medications without the need for more needles.

Infusion therapy isn’t just for cancer, though. It’s also used in the treatment of:

Another alternative is to have aportsurgically implanted under your skin. In future treatments, the needle can be inserted into the port to access the vein without sticking you. The port will be surgically removed after you’ve completed all your treatments.

Whatever the setting, IV therapy is administered by nurses or other trained medical professionals. The procedure requires careful monitoring, so if the process is going to take more than a few minutes, there is usually some sort of control mechanism attached to the line to ensure proper delivery. Frequent or remote monitoring always accompanies infusion therapy.

Depending on the medication, it may be pre-prepared or prepared just prior to use.

If the infusion is expected to take several hours in an outpatient setting, you’ll typically be offered a reclining chair. You can bring reading materials, blankets, or other items to help you feelcomfortable.

Before beginning, your nurse will perform a series of checks to verify:

  • your identity
  • the right medication and the right dose
  • the right time, as some medications are given at a specific time of day or for a specific length of time
  • the right route, such as vein, injection, or port

Once the medication dispenses, the catheter will be removed.

Insertion of an IV needle often goes smoothly, but it can be challenging, especially if you have small veins.

If you need to have many infusions, it can cause scar tissue to form over time, which may cause damage to your veins. Risks of IV therapy can include:

Sometimes, a needle can become dislodged, allowing the medication to get into surrounding tissues. With some medications, this can be harmful.

Other risks depend on the type of medications you’re receiving. Any new medication can cause your body to react strongly. If you’re going to have a reaction, it typically happens the first time you get a particular treatment.

Your doctor will explain the potential risks of your therapy and signs to watch for. The signs of infusion reaction typically include:

  • cough
  • facial flushing
  • fever, chills
  • 头痛
  • itching
  • muscle or joint pain and stiffness
  • nausea
  • rash or hives
  • 气促
  • swelling of hands, legs, ankles, or feet
  • swelling of the tongue, lips, or eyelids

Infusion therapy is the administration of medication or fluids in a controlled method. It’s done most often intravenously or subcutaneously.

Since the timing can be controlled, it’s used to deliver chemotherapy drugs and other medications that need to enter your system slowly. It can also be used to deliver drugs into your bloodstream quickly in the case of a life threatening emergency.
