An injection is a shot, or a dose of medicine given by way of a syringe and a needle. Since the 1600s, injection has been used to mean “forcing a fluid into a body,” from the Latin inicere, “to throw in” or “to throw on.”

The definition of an injection is the act of pumping something in, or something that has been pumped in. An example of an injection is a flu shot. Something that is injected, especially a dose of liquid medicine injected into the body. …

In medical care, an injection is the introduction of a drug, vaccine, contraceptive or other therapeutic agent into the body using a needle and syringe. Injections are among the most common health care procedures throughout the world.

Learn about the 4 types of injection: intradermal, subcutaneous, intravenous and intramuscular injections, and what they are used for in Singapore.

The pain of most injections is usually brief. The fear and anticipation of getting a shot is often worse than the shot itself. Our medical assistants give injections all day long. They are fast, efficient, and often over before the kids know it, but there are still some things that we can do to minimize the discomfort.

Cervical Cancer Vaccine Called Most Painful Shot.

Shots given in muscles — like the deltoid in the upper arm where flu shots are usually given — tend to be more painful than ones that aren’t injected into the muscle, Stewart said. “Muscles have little tight fibers, and if you separate it by sticking a needle in there, you can cause an inflammatory reaction,” she said.

Treatment for post-injection inflammation

1. Cold packs. These help reduce swelling, itching, and pain.
2. Over-the-counter pain medicines. These help reduce pain and inflammation.
3. Prescription medicine. These treat infection.

Use a Cold or Warm Compress Afterward Heat brings more blood to the area and can relax the surrounding muscles when it is applied. A cold compress can reduce swelling around the injection site.

Can You Reduce Pain or Swelling After Vaccines?

1. Make sure to move your arm around after the vaccine.
2. Take a pain reliever for one or two days after receiving vaccination to help with soreness and swelling.
3. Rotate a warm pack on and off the injection site.

Pain, redness and swelling at the injection site are common reactions to vaccines. These reactions generally last one to two days but can sometimes last longer.

How To Give A Painless Injection

1. With your “nonshooting” hand, grab as big a chunk of skin plus underlying fat as you can hold comfortably.
2. Hold the syringe like a dart, with the thumb and first three fingers of either hand.
3. Now comes the most important part: Penetration must be rapid.

The need for needle pain intervention

1. Numb the skin. Using topical anesthesia to numb the area where the needle will be inserted can significantly lower the amount of pain.
2. Give a pacifier or allow breastfeeding.
3. Don’t restrain the child.
4. Distract, distract, distract.
5. Watch what you say.
6. Act it out.
7. Speak up.

In conclusion, smaller needles can reduce pain and provide other advantages that can increase patient compliance. Fine needles of 33–31 gauge have already gained clinical acceptance and still smaller microneedles are under development.

The microbes in injection substances, injection equipment or already-existing on the skin, can enter the body causing very serious infections. Similarly, incorrect injection techniques or erroneous injection locations, can cause blood vessel breakage, muscle or nerve damage and paralysis.

If needle insertion results in swelling and bruising, you’ve got a blown vein. It may sting and can be uncomfortable, but it’s harmless. The healthcare provider typically applies a little pressure to the injection site to minimize blood loss and swelling. After a few minutes, they clean the area to prevent infection.

Side Effects of the Depo-Provera Shot

• Uneven menstrual periods or no periods at all.
• Headaches.
• Nervousness.
• Depression.
• Dizziness.
• Acne.
• Changes in appetite.
• Weight gain.

If a nerve is hit, the patient will feel an immediate burning pain, which can result in paralysis or neuropathy that does not always resolve.

Nerves are fragile and can be damaged by pressure, stretching, or cutting. Injury to a nerve can stop signals to and from the brain, causing muscles not to work properly, and a loss of feeling in the injured area.

Where you give the injection is very important. The medicine needs to go into muscle. You do not want to hit a nerve or a blood vessel.

What are the complications of intramuscular injections?

• severe pain at the injection site.
• tingling or numbness.
• redness, swelling, or warmth at the injection site.
• drainage at the injection site.
• prolonged bleeding.
• signs of an allergic reaction, such as difficulty breathing or facial swelling.

The three main types of injections include:

• Subcutaneous (into the fat layer between the skin and muscle)
• Intramuscular (deep into a muscle)
• Intravenous (through a vein)

The intramuscular route allows the rapid absorption of drugs into the circulation. Using the correct injection technique and selecting the correct site will minimise the risk of complications.

Injecting a small air bubble into the skin or a muscle is usually harmless. But it might mean you aren’t getting the full dose of medicine, because the air takes up space in the syringe.

When a person receives fluids intravenously (through an IV bag, for example), a saline solution is sometime used. Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death.

Most women experience breakthrough bleeding or spotting for the first several months after they begin getting the shot. It may take six months to a year before the side effects end and your periods return to normal. For some women, their period may go away entirely.

Move air out of your body by moving your body Force gas out of your body by exercising: walking, jogging, or doing light aerobics. Lie on your stomach, then curl your knees in toward your chest, stretching your arms forward as far as they will go, and then arch your back.
