They include such issues as:. In general for IM intramuscular injections you would use a 21 to 23 gauge needle 1 to 1. In a child you use a 1 inch long, 25 to 27 gauge needle. In obese patients, 1.
Intramuscular Injections: Injecting At Home
SQ medications are deposited into the loose connective tissue just below the dermis. This is not richly supplied with blood vessels so the absorption rate is slow.
There are many pain receptors in this tissue so only non- irritating, water-soluble medications in small doses should be given by the SQ route. Intramuscular tissue is richly supplied with blood vessels so the medication is more rapidly absorbed by this route.
There are few pain receptors so viscous and irritating drugs can be injected into the muscle tissue with less discomfort. In choosing a site consider deep muscle tissue for the most irritating or viscous medications to reduce the possibility of tissue damage.
Using a Z-track method may be recommended as well. Care must be taken to avoid blood vessels, and you must always aspirate with an IM injection to ensure that you have not hit a vessel.
If you aspirate blood, remove the needle and prepare a new syringe. Never inject the blood back into the tissue. SQ sites typically used are the upper arm, thigh, and abdominal areas in children and adults alike.
With frequent injections such as insulin, the site should be rotated with each dose. Preferred IM sites include the deltoid upper arm and the ventrogluteal or rectus femoris, and vastus lateralis in children. In adults IM sites include the deltoid, ventrogluteal, vastus lateralis and dorsal gluteal with careful land marking to avoid the sciatic nerve.
In many families, one person takes on most of the responsibilities for injections.
However, there may be problems when that person is not there. It is important for all regular caregivers to share the responsibility of giving the injection. Your child should feel safe and confident with any of them. Single-parent families should get the help of a friend or relative.
Some families work out a schedule.
One parent might take care of the morning injections and the other parent looks after evening injections. Sharing the burden is also important to cope with the daily demands of your child's condition and to prevent parent burnout.
The injection site depends on your child's age.
How to Determine Needle Size
The size of the needle also influences the location of the injection site. The size of the needle depends on the weight of your child and the type of drug they are taking.
The diameter of the needles also varies depending on your child's age. Needles with larger diameters have smaller gauge numbers.
If the injection you are giving is more than 1 mL in volume, check with your health care provider about which location is appropriate for your child. For newborns, the IM injection site is the front outer side of the thigh. To inject into the thigh, the needle length must be 16 mm.
Use a 23 to 25 gauge needle. For infants, the IM injection site is the front outer side of the thigh. Do not use the inner thigh or back of the thigh.
Divide the thigh into thirds; the injection site is in the middle third section. To inject into the site, the needles must be 16mm to 22mm long. Use a 22 to 25 gauge needle. Your baby's doctor may give you a longer needle depending on the size of your child. The needle must be long enough so that it will reach deep into the muscle. It should reach pass the tissue just above the muscle, which is the subcutaneous SC tissue. This helps to reduce irritation to the subcutaneous tissue which can cause pain associated with IM injections. For older children the size of the needle depends on the sex and weight of your child.
Generally, a needle that is 25 mm to 38 mm long can be used for adolescents. This can happen from time to time. It is not harmful. It usually means the needle has nicked a tiny blood vessel. To reduce the chance of bruising, apply gentle pressure to the site with a dry piece of cotton or a clean finger after injecting. Also, remember not to insert the needle too slowly. If you have too much bruising, consult your health care team.
