Anesthesia is a complex of methods used by patients during operations and painful manipulations to protect their lives and health.
Anesthetics are common and local action. Depending on the method of administration of anesthetics, ше is divided into inhalation and non-inhaling.
With inhalation anesthesia, gas or vapors of anesthetics enter the patient’s body when inhaled through an anesthetic mask, an intubation tube or a tracheotomy cannula. This narcosis is characterized by simplicity of the method, easy accessibility and high degree of controllability.
A characteristic feature of non-anional anesthesia is poor controllability: the complete dependence of its course on the duration of biological transformation (neutralization and excretion) of an anesthetic in the body.
In addition, combined methods of general anesthesia can be performed by non-invasive methods: neuroleptanalgesia, central analgesia, etc. Unlike general anesthesia, when using local anesthesia, consciousness is not excluded in patients.
