What is the purpose of anaesthesia in surgery?
When surgery used to be done without anaesthesia, the types of operations were limited, and pain was a big issue. The purpose of anaesthesia is to relieve pain and the only way out of this was using analgesics - a pain relief agent. Around 1844, general anaesthesia came into play using nitrous oxide, chloroform and ether. Chloroform and ether alter a patient’s consciousness and put them to sleep while nitrous oxide has pain-relieving properties.
