Video guides on the three main types of injections, which are intramuscular, subcutaneous and intradermal, are available online at websites such as FreedomMedTeach.com, DailyMotion.com and HealthPhone.org. The types of injection differ in how and where they are administered.
Intramuscular injections are injected into deep muscle tissue, notes Novosanis. This allows faster absorption of the medication. Influenza vaccinations are a type of intramuscular injection. Dailymotion has a video on how to give an intramuscular injection. The video is created by LifeXMD, a hormone replacement clinic.
Subcutaneous injections are shot into the fat layer that lies between the epidermis and the muscle, explains Drugs.com. These injections are used to give small doses of medication such as insulin to patients. Subcutaneous injections can be given in the abdomen, thigh and upper arm, among other areas. Freedom Fertility Pharmacy has videos on giving several kinds of injections, including a basic subcutaneous injection given in the abdomen.
Intradermal injections are given in the dermal layer of the skin that lies underneath the epidermis, according to Novosanis. It has a high number of immune cells. Delivering an intradermal injection requires a high level of skill. Healhphone's video shows how to give a newborn an intradermal injection of the BCG vaccine for tuberculosis.
