Contraindications

Contraindications are features of the nature, localization, course of the pathological process and the disorders caused by it. They prevent a particular treatment or test from being performed on a patient. Contraindications can be absolute or relative. Absolute contraindications are conditions in which the use of a given method of treatment or research is impossible. Relative contraindications are situations where the use of a treatment or research method is possible, but requires additional conditions or restrictions.

A contraindication to the use of a treatment method may be the presence of certain diseases or conditions in the patient. For example, some medications may be contraindicated in the presence of acute infectious diseases, allergic reactions, or other conditions.

Another example would be a contraindication for the use of a particular test. For example, magnetic resonance imaging (MRI) may be contraindicated if the patient has metal implants.

In addition, contraindications may be associated with the localization of the pathological process. For example, radiation therapy may be contraindicated for brain tumors because the radiation can damage healthy tissue.

Also, contraindications may arise due to the characteristics of the pathological process, for example, with the rapid progression of the disease or the presence of complications.

In general, contraindications are an important consideration when choosing a treatment or testing a patient. They allow you to avoid unwanted consequences and ensure maximum effectiveness of treatment.

**Relative contraindication.** Absolute contraindications are strictly specific and fixed, they completely exclude the possibility of carrying out a specific type of treatment and are indicated by a large
