Before the Han Dynasty, the treatment of trauma was faced with a problem. When dealing with trauma, patients were often in unbearable pain, so that various restraints were used to control the patient.
According to the records of the Three Kingdoms, Guan Yu was shot through the left arm by a poisonous arrow. Although the wound healed, the residual poison remained on the bone, which often brought pain. The famous doctor Hua Tuo cut his arm again and scraped the bones to remove the toxins. Although the whole process was dripping with blood, Guan Yu could still drink and eat meat, chat and laugh with others as usual. This is the story of scraping the bones to cure the poison. Use scraping bone to cure poison as a metaphor for those who are strong-willed.
But ordinary people could not bear this kind of pain, until Hua Tuo, a famous doctor in the Eastern Han Dynasty, invented the earliest anesthetic, Ma Fei San, After that, the problem was solved. Let the patient take Mafei San with alcohol first, and then the operation can be performed without consciousness, so as to relieve the pain of the patient and make the operation go smoothly.
