Methods of injections infusions

Administering three types of injections.

The first being intradermal injections, this technique involves the injection of the fluid into the top layer of the skin which is soft. This technique is mostly used for treating certain health problems mainly many allergies.

The liquid drug is inserted with an intradermal injection, which will lie just beneath the skin surface in between the layers of the skin. The needle is extremely tiny and inserts the fluid under the skin.

Another type of injection is the intramuscular injections. This is the most common way of injecting medication directly into a patient. The medicine from the injection is absorbed directly into the muscle. It allows the medicine to gain easy access to the blood stream. This type of injection is the best and safest way of injecting medication into a patient.

The third type of injection is subcutaneous injections. Such types of injections are administered when the medicine needs to be absorbed slowly. In this case the needle must go through the first two layers of skin that is the epidermis and dermis. The needle should then reach the subcutaneous tissue which is the fatty layer of the skin. Medicines administered through subcutaneous injections have the least chance oh having an adverse reaction. The most common medicine given in this kind of way is insulin.

In all these injections, the size of the needle varies, the deeper the injection the longer the needle should be.
For an intradermal injection the needle should be the shortest available because it is inserted just under the first layer of the skin. for the intramuscular injection the needle should be at least a few inches long and for the subcutaneous injection are roughly a few inches long.
