What is anesthesia?

Literally, the word "anesthesia" is translated from the Greek language as "without feeling." This phenomenon can be characterized as a reduction in the sensitivity of the whole body or its separate part. Such a process can reach an absolute lack of perception of one�s own state or environment. In this article we will explain what anesthesia is and what types it has.

Description of the phenomenon and types

Anesthesia is triggered by impaired transmission of nerve impulses at different levels. It can be damage to sensory nerves or receptors, impaired perception of nerve impulses caused by brain damage, as well as various mental illnesses.

Medical anesthesia is used in anesthesiology for the purpose of pain relief in various medical procedures involving pain syndrome, as well as during surgical interventions. It is local or common. Local ensures the lack of sensitivity of a particular part of the body, and general (it is often called anesthesia) implies a complete loss of sensitivity.In the second case, the degree of impairment of consciousness is different.

Local anesthesia is divided into types on the site in which the transmission of nerve impulses is blocked. So, there are spinal, epidural, combined spinal-epidural, infiltrative and conduction anesthesia.
