Get to know the Intravenous Injection Method, How to Enter Drugs Through Blood Vessels


IV or intravenously is a method of administering drugs through intravenous injection or infusion. Actually, intravenous itself means 'in veins'. So the drug will be inserted directly into the vein using a needle or tube called the IV catheter. This intravenous injection procedure must be performed by a professional medical expert.

When does the intravenous injection method need to be done?

The method of intravenous injection is medical action that must be carried out by and under the supervision of a professional medical expert. Usually, this method of intravenous injection is done in a hospital to treat patients who need control over the dosage of the drug. The method of intravenous injection can also accelerate the absorption of drugs for patients. An example is in patients with heart attacks, strokes, or poisoning.

Intravenous injection will be done when the patient needs to get medication whose dose must be slowly inserted into the body. Valves and hoses used in the method of intravenous injection will make medical personnel easily adjust the dosage and time specified so that the drug can be absorbed properly.

The most common type of intravenous

Usually a standard type of intravenous will be used in the short term or at most 4 days. Standard intravenous injection using only a needle will be inserted into a vein in the wrist, elbow or back of the hand. The catheter will then be inserted to replace the needle.

The standard intravenous catheter is usually used for the two types of IV methods below:

  • Intravenous injections, use ordinary syringes to inject drugs into the catheter. Used to deliver drugs to blood vessels in just one dose.
  • Intravenous Infusion, is used to deliver drugs to the veins constantly but little by little, consisting of pump infusions and drops of infusion.

Generally, this type of intravenous standard is given in cases of hospitalization, surgery, pain medication, nausea treatment, or antibiotics.

Long-term intravenous use

If the intravenous injection method is used for the long term as in chemotherapy patients, usually medical personnel will prefer using the Central Vein Catheter (CVC) compared to standard IV. CVC is usually inserted through a vein in the neck, arm, or groin area.

So, the catheter or drug entry will be made first at the beginning of the treatment and will not be released until the treatment is complete. CVC can be used for a longer period of time, ranging from a few weeks to several months.

The three main types of CVC:

  • Peripherally inserted central catheter (PICC) - inserted into the elbow on the upper arm directly into the vein.
  • Tunneled catheter - a catheter placed on a vein in the neck or heart during a short surgical procedure.
  • Implanted ports - implanted or implanted under the skin in veins in the neck or chest, usually used during surgery.

To find out which type of intravenous you need, you should consult this with your doctor.

Side effects of using intravenous

Although this action is quite safe, but the side effects that may arise from intravenous use are:

  • Infection at the injection site.
  • Damages blood vessels at the injection site.
  • Air embolism (formation of air bubbles in the heart and lungs which can inhibit blood flow.
  • Blood clots.
