Get to know the method of intravenous injection, how to enter the drug through a vein: function, dosage, side effects, how to use it

IV or intravenous is a method of giving drugs by injection or intravenous infusion. In fact, intravenous itself means 'inside the vein'. So the drug will be inserted directly into the vein using a needle or tube called an IV catheter. This intravenous injection procedure should be performed by a medical professional.

When is the intravenous injection method necessary?

The intravenous injection method is a medical procedure that must be performed by and under the supervision of a medical professional. Usually, this method of intravenous injection is performed in the hospital to treat patients who need control over drug doses. The intravenous injection method can also speed up drug absorption for the patient. Examples are in patients with heart attack, stroke, or poisoning.

Intravenous injection will be performed when the patient needs to receive a drug whose doses must be slowly introduced into the body. The valves and tubes used in the intravenous injection method will make it easy for medical personnel to adjust the dose and time specified so that the drug can be absorbed properly.

The most common type of intravenous

Usually the standard intravenous type will be used for a short period or a maximum of 4 days. The standard intravenous injection uses only a needle to be inserted into a vein in the wrist, elbow, or back of the hand. The catheter will then be inserted to replace the needle.

Standard intravenous catheters are usually used for the following two types of IV methods:

• Intravenous injection, use a regular syringe to inject the drug into the catheter. It is used to deliver drugs to a vein in just one dose.
• Intravenous Infusion, used to give drugs to the blood vessels constantly but gradually, consisting of a pump infusion and a drip infusion.

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

Long-term intravenous use

If the intravenous injection method is used for a long period such as in chemotherapy patients, usually medical personnel will prefer to use it Central Venous Catheter (CVC) versus standard IV. CVC is usually inserted through a vein in the neck, arm, or groin area.

Thus, the catheter or drug entry route will be created at the start of treatment and will not be removed until 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 is placed in a vein in the neck or heart during a short surgical procedure.
• Implanted port - implanted or implanted under the skin in a vein 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 procedure is quite safe to do, the side effects that may arise from intravenous use are:

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