The 4 Types Of Injections That Exist
There are four types of injections and we classify them according to the route of administration. Injectable drugs are parenteral and come in two types of glass containers: ampoules and vials.
The ampoules are a closed system, have a long neck and a constriction at the base. Once you have broken the opening or the “neck”, you can easily extract the medicine.
The bottles are also a closed system, have a short neck and a hard plastic cap lined with metal. You need to inject a volume of air equal to the volume of the desired substance to extract their contents.
The medicine may be ready for use as it is or may require another substance to mix. Here are the four types of injections, as well as the specific characteristics of each!
Types of injections
1. Intravenous injections
3. Subcutaneous injections
- Insulin
4. Intramuscular injections
This type of injection is used to administer drugs to muscles. The most commonly used drugs are vaccines and other substances such as painkillers, anti-inflammatory drugs, corticosteroids and antibiotics.
It is a faster route of absorption than the subcutaneous one. In addition, the effect appears in about 15 minutes. The volume injected is less than 15 milliliters and the syringe is 2 or 5 milliliters, with a medium green conical needle for adults.
The most common areas of administration are the upper outer quadrant of the buttocks, the deltoid and the side of the leg.
To administer these injections, the doctor inserts a needle directly into the muscle at a 90-degree angle. Then adjust the loaded syringe and pull the plunger back to make sure it has not punctured a blood vessel.
The doctor slowly inoculates the medicine, as this is a painful way. The muscle fibers are glued together and come off when the fluid enters, causing a lot of pain. The doctor then removes both the syringe and the needle at the same time.
