Injection

Injection is the introduction of medications or other liquids into the body using a syringe (usually injections introduce those medicinal substances that can be destroyed during digestive reactions in the body if taken orally).

The main types of injections are:

1. Intradermal (or intradermal) (intracutaneous or intradermal)

2. Subcutaneous, such as insulin administration

3. Intramuscular (intramuscular) - in this way substances that are slowly absorbed in the body are introduced

4. Intravenous - this is how medications are administered that are quickly absorbed into the body

Injections can also be given through enemas (rectal injection).

Injection: Introduction of Medicines and Liquids into the Body

Injection is the process of introducing medications or other liquids into the body using a syringe. This method is used when it is necessary to bypass the digestive system and deliver the substance directly into the blood or into the desired tissue of the body. Injections are one of the most common methods of administering drugs and have various forms and methods of application.

There are several main types of injections, each of which has its own characteristics and is used in different situations:

1. Intradermal (intradermal) injection: This type of injection is performed by injecting a small amount of medication into the top layer of the skin. It is commonly used for diagnosis and testing, such as testing the body's response to allergens or administering the Mantoux test to detect tuberculosis.

2. Subcutaneous injection: In this case, a needle penetrates the skin and injects the drug into the layer below the skin. This type of injection is widely used for self-injections, such as insulin for diabetes. Subcutaneous injections are also used to release drugs slowly and gradually into the body.

3. Intramuscular injection: With this injection method, the drug is injected into the deep layers of the muscle. This allows rapid absorption and distribution of the drug. Intramuscular injections are usually used for drugs that are slowly absorbed into the body and require a long-lasting effect.

4. Intravenous injection: In this case, the drug is injected directly into a vein. This method ensures the fastest and most complete absorption of the drug, as it immediately enters the bloodstream and is distributed throughout the body. Intravenous injections are widely used in situations that require immediate action, such as serious conditions, acute pain, or to administer large doses of medications.

Alternatively, injections may be given using an enema, in which the drug is given through the rectum (rectal injection). This method is usually used to deliver drugs when other routes of administration are impossible or ineffective.

Injections are a powerful tool in medicine that allows drugs to be delivered accurately and efficiently. They bypass the digestive system and ensure rapid action of medications. However, injections require special skills and must be carried out with certain precautions to avoid possible complications.

When administering injections, sterility must be maintained to prevent infections. Syringes and needles should be disposable or properly sterilized before reuse. It is also important to choose the right injection site and insert the needle correctly into the tissue or vein.

In addition, injections may cause certain side effects, such as pain, irritation, or allergic reactions. It is important to monitor for possible side effects and consult your doctor if they occur.

In conclusion, injections are an important method of introducing medications and other fluids into the body. They provide precise and efficient drug delivery and bypass the digestive system. However, administering injections requires certain skills and precautions. If injections are necessary, you should always contact qualified medical personnel who will ensure the correct and safe administration of medicinal substances into the body.

Injections are a common method of introducing drugs into the body. This is due to the fact that not all substances can be taken orally, as they may be destroyed and ineffective. In such cases, injections help deliver the medicine into the blood without wasting time on its absorption and digestion.

When using the injection method, the rules of asepsis and antisepsis must be observed to prevent the development of unwanted side effects. Depending on the diagnosis, the doctor prescribes a certain type of injection. For example, to deliver insulin inside the body, the drug is injected through the subcutaneous fat layer. This method is the most popular because it allows you to evenly distribute the drug throughout the entire injection area. Subcutaneous and intravenous injections are used when it is necessary to quickly deliver drugs into the bloodstream, for example, in emergency medical care. Usually, to carry out these procedures, the doctor uses special disposable devices (syringes and needles).
