Subcutaneous injections can lead to localised cellulitis, granuloma formation and abscess. The COVID-19 vaccine has shown to have high efficacy if given correctly intramuscularly. Subcutaneous injection can happen inadvertently (figure 1), affecting efficacy of vaccination and potentiate local adverse events.
Can intramuscular injection be given subcutaneously?
For all intramuscular injections, the needle should be long enough to reach the muscle mass and prevent vaccine from seeping into subcutaneous tissue, but not so long as to involve underlying nerves, blood vessels, or bone (15,19-22).
What happens if you inject air in a subcutaneous injection?
What would happen if an air bubble was accidentally injected into your child? It is not harmful to inject an air bubble under the skin. However, if you are injecting air rather than medicine, your child may not be getting the full dose, which may mean they are not being properly treated.
What is the advantage of an intramuscular injection over a subcutaneous injection?
Intramuscular injections are absorbed faster than subcutaneous injections. This is because muscle tissue has a greater blood supply than the tissue just under the skin. Muscle tissue can also hold a larger volume of medication than subcutaneous tissue.Where do you give a subcutaneous injection?
- the upper outer area of the arm.
- the front and outer sides of the thighs.
- the abdomen, except for a 2 inch area around the navel.
- the upper outer area of the buttocks.
- the upper hip.
What is the disadvantage of subcutaneous route?
The slower absorption is a common disadvantage of subcutaneous administration because there is less blood flow to quickly absorb drug; however, this may be an advantage as well, in that lower doses of drugs may last for longer periods.
What is the difference between intramuscular and subcutaneous?
The key difference between subcutaneous intramuscular and intravenous injection is that in subcutaneous injection, the drug is injected under the skin, while in intramuscular injection, the drug is delivered deep into the muscles, and in intravenous injection, the drug is given directly into a vein.
At what angle do you give an IM injection?
a 90-degree angle and inject all of the vaccine in the muscle tissue. by 1 inch if possible.What are the disadvantages of intramuscular route?
- Expert and a trained person is required for administrating the drug by IM route.
- The absorption of the drug is determined by the bulk of the muscle and its vascularity.
- The onset and duration of the action of the drug is not adjustable.
Insert the needle quickly at a 45- to 90-degree angle. Inserting quickly causes less pain to the patient. Subcutaneous tissue is abundant in well-nourished, well-hydrated people. For patients with little subcutaneous tissue, it is best to insert the needle at a 45-degree angle.
Article first time published onIs bleeding After im injection normal?
Light bleeding at the injection site is normal, but a person can use a bandage if necessary.
Is intramuscular deeper than subcutaneous?
Subcutaneous injections are administered in the fat layer, underneath the skin. Intramuscular injections are delivered into the muscle. Intradermal injections are delivered into the dermis, or the skin layer underneath the epidermis (which is the upper skin layer).
What is the advantage of subcutaneous route?
As subcutaneous tissue has few blood vessels, the injected drug is diffused very slowly at a sustained rate of absorption. Therefore, it is highly effective in administering vaccines, growth hormones, and insulin, which require continuous delivery at a low dose rate.
What are the advantage of subcutaneous?
The main advantage of a subcutaneous transposition is that it is easy to perform. It is a good procedure when subluxation and traction on the nerve are contributing to the patient’s symptoms. The primary disadvantage is that the nerve may be hypersensitive after surgery because of its new superficial location.
Why are subcutaneous injections given by a hypodermic needle?
The drug needs to be injected into the fatty tissue just below the skin. Some areas of the body have a more easily accessible layer of tissue, where a needle injected under the skin will not hit muscle, bone, or blood vessels.
Can you give 2ml in deltoid?
Immunizations and medication doses between 1-2 milliliters should be administered in the deltoid muscle. Medication doses between 2-3 milliliters should be administered in the ventrogluteal muscle.”
Can you inject 2 ml in deltoid?
Deltoid muscle This site is used for small medication volumes and administration of routine immunizations in adults. If the deltoid site is used, no more than 2 ml of medication should be administered at one time.
Which route of drug administration is most likely to lead to the first pass effect?
It happens most commonly when the drug is administered orally. The drug then is absorbed in the GIT and enters enters the portal circulation before entering the systemic circulation.
Do you have to pinch skin for subcutaneous injection?
Angle of injection PHE (2013) recommends that subcutaneous vaccinations are given with the needle at a 45-degree angle to the skin and the skin should be pinched together (PHE, 2013).
Which two techniques apply when giving a subcutaneous injection?
- Holding the needle upwards, tap the syringe gently to move any air bubbles towards the needle.
- Push the plunger gently to remove the air bubble and squirt a small amount of the medicine into the air.
- Lift the skin in the chosen injection area between your thumb and index finger.
When administering a subcutaneous and or an intramuscular injection you would gently pull back on the plunger to?
Gently pull back on the plunger of the syringe to check for blood. After inserting the needle under the skin, lift your hand away that is holding the skin. Wait 5 seconds, and then pull back on the syringe to remove the needle from your skin. Dispose of the syringe and needle properly, using a sharps container.
How can you make an injection hurt less?
Cough. Research shows that coughing once before and once during the shot can help some people feel less pain. Relax your arm. If you’re tense, it can make a shot hurt more — especially if you tense up the area where you’re getting the shot.
What is the best way to give an intramuscular injection?
Hold the skin around where you will give the injection: With your free hand, gently press on and pull the skin so that it is slightly tight. Insert the needle into the muscle: Hold the syringe barrel tightly and use your wrist to inject the needle through the skin and into the muscle at a 90 degree angle.
Which is the most painful injection?
The groundbreaking vaccine that prevents cervical cancer in girls is gaining a reputation as the most painful of childhood shots, health experts say. As Austin Powers would say; “Ouch, baby.
What are the potential complications of subcutaneous injections?
- 1.) Pain. The thought of injection is already painful—from blood checkups to surgeries. …

What are the contraindications of subcutaneous injection?
Contraindications. Subcutaneous injections should not be given at any site where a severe dermatitis or cellulitis exists.
What are the disadvantages of intramuscular or subcutaneous injection of medication?
Intramuscular injections commonly result in pain, redness, and swelling or inflammation around the injection site. These side effects are generally mild and last no more than a few days at most. Rarely, nerves or blood vessels around the injection site can be damaged, resulting in severe pain or paralysis.
