Intradermal InjectionIntradermal Injection
Administered usually into the forearm. Other sites include the upper chest, the upper arm, and shoulder blades.
- given into the dermal layer of the skin, just under the epidermis.
- Injected at about a 10 – 150 angle.

Intradermal InjectionIntradermal Injection
- Only a very small dose can be given < 0.5ml, usually 0.01 – 0.1ml.
- Used for TB & allergy testing.
- As there is a reduced blood supply, drug absorption can occur slowly.

Subcutaneous InjectionSubcutaneous Injection
Administration sites include: abdomen, anterior thigh, and the fat pad over the deltoid muscle in the upper arm
- given under the skin into the loose fat & connective tissue
- Absorption of drug is via the capillaries ... slower acting than IM or IV
- slow, steady absorption

Injection RoutesInjection Routes
Subcutaneous- should never be given into scar tissue, a
lesion or over a bony prominence- As subcutaneous tissues contain pain
receptors, only a small volume < 2ml should be given
- Unsuitable for any drug that may be irritating to the tissues

Injection RoutesInjection Routes
Intramuscular - given into the muscle tissue below the fatty subcutaneous layer
- Rich blood supply ... readily absorbed into the bloodstream
- Suitable for drugs that are soluble, non irritant to soft tissue & require quick absorption
![Page 7: Introduction to Injections Administer and Monitor Medication in the Work Environment Topic 8 Intradermal.](https://reader035.fdocuments.net/reader035/viewer/2022081000/56649e8f5503460f94b92ecb/html5/thumbnails/7.jpg)
Injection RoutesInjection Routes
Intramuscular
- Up to 4ml can be injected without causing undue discomfort
- Solution can be more viscous than that given by SC route – permits thicker, oil based compounds

Administering injectionsAdministering injections
Intradermal
- these medications are very potent requiring very slow absorption
- Only very small amounts can be administered 0.01 – 0.1ml
- The needle is inserted at an angle of 10 – 15 0 to the skin
- a small bleb should appear on the surface of the skin
![Page 9: Introduction to Injections Administer and Monitor Medication in the Work Environment Topic 8 Intradermal.](https://reader035.fdocuments.net/reader035/viewer/2022081000/56649e8f5503460f94b92ecb/html5/thumbnails/9.jpg)
Administering injectionsAdministering injections Intradermal- if a bleb doesn’t appear, most likely the
medication has entered the sc tissue & any results from the skin testing will be invalid
- The inner forearm & upper back are the most common sites used

ProcedureProcedure
Intradermal injection - perform the standard protocol for beginning the procedure
- Select injection site & clean skin with an alcohol swab; allow to dry
- Expel any air from the syringe- Pull the skin taught & insert the needle into
the skin approximately 3mm at a 10 – 150
angle, bevel face upwards

ProcedureProcedure
Intradermal- do not aspirate but inject slowly – it should
produce a small bleb under the skin- Withdraw the needle smoothly & wipe the
injection site- Do not massage – may disperse
medication into sc layer- Complete the standard protocol for the
completion of a procedure

Things to consider…Things to consider…
Client must be observed closely as they may have a severe anaphylactic reaction if a test allergen is being injected
The site chosen should be free of lesions & only lightly pigmented – enables clear inspection & assessment of any changes from the injection
