Injections
An injection is the act of delivering a liquid drug into a person’s body using a needle (usually a hypodermic needle) and a syringe. It is a form of parenteral administration, which means delivering drugs via a route other than the digestive tract. Types of parenteral injections include:
- Subcutaneous (SC)
- Intramuscular (IM)
- Intravenous (IV)
- Intraperitoneal
- Intracardiac
- Intra-articular
- Intracavernous
Product Description
Injections are one of the most common healthcare procedures, with over 16 billion administered yearly in developing and transitional countries. Of these, 95% are for curative care, 3% for immunizations, and the remainder for purposes like blood transfusion. Sometimes, “injection” and “inoculation” are used interchangeably; what matters most is what is being administered.
Guidelines
In pharmaceutical use, infiltration refers to saturating a tissue volume with a drug, filling the interstitial spaces. Local anesthetics are typically infiltrated into the dermis and hypodermis for localized effect.
Clinical Research
- Intramuscular injection (IM): Delivers medication into the muscle. Commonly used for vaccines.
- Subcutaneous injection (SC): Administers drugs beneath the skin layers into subcutaneous tissue (e.g., insulin, heparin).
- Intradermal injection (ID): Delivers drugs just under the skin surface, often for local anesthetics before procedures.
