General anaesthesia

General anaesthesia eliminates pain perception in the whole body as well as consciousness for a specific time; the patient is in a sleep-like state.
General anaesthesia is carried out with a combination of different drugs. Sleeping drugs, analgesics and drugs to relax the musculature are combined and injected (usually through an infusion already in place) or mixed into the breathing air.
During surgery, the patient usually wears a breathing mask to administer more oxygen in order to support respiration.

For operations lasting more than one hour, a breathing tube is often inserted into the trachea to enable better and more reliable monitoring of respiration.

After anaesthesia, a variety of symptoms may occur, such as hoarseness, swallowing pain, headache, nausea and vomiting, sensation of cold and chills, urination problems or pain in the operated area. Today, these side effects have become substantially rarer and can be treated better and more effectively.
