The General Anesthesia Quiz! Trivia

The general anaesthesia quiz trivia! General anaesthesia is a form of anaesthesia in which a patient is rendered completely unconscious as a procedure is being carried out on him for a long time. Do you know what other types of anaesthesia exist, what sets them apart and the different types of drugs administered to a patient? In this quiz, you will refresh your understanding of some of the main facts surrounding general anaesthesia.
