Because of this, despite Hua Tuo's reported success with general anesthesia, the practice of surgery in ancient China ended with his death. [57] The name mafeisan combines ma (麻, meaning "cannabis, hemp, numbed or tingling"), fei (沸, meaning "boiling or bubbling"), and san (散, meaning
Attempts at producing general anaesthesia can be traced throughout recorded history in the writings of the ancient Sumerians, Babylonians, Assyrians, Egyptians, Greeks, Romans, Indians, and Chinese. During the Middle Ages, scholars made advances in the Eastern world and Europe. The Renaissance saw advances in anatomy and surgical technique ...
Anesthesiology, anaesthesiology or anaesthesia is the medical specialty concerned with the total perioperative care of patients before, during and after surgery. [1] It encompasses anesthesia, intensive care medicine, critical emergency medicine, and pain medicine. [2]
General anaesthetics (or anesthetics) are often defined as compounds that induce a loss of consciousness in humans or loss of righting reflex in animals. Clinical definitions are also extended to include an induced coma that causes lack of awareness to painful stimuli, sufficient to facilitate surgical applications in clinical and veterinary practice.
Anesthesia is a combination of the endpoints (discussed above) that are reached by drugs acting on different but overlapping sites in the central nervous system. General anesthesia (as opposed to sedation or regional anesthesia) has three main goals: lack of movement , unconsciousness, and blunting of the stress response. In the early days of ...
The Meyer-Overton correlation for anaesthetics. A nonspecific mechanism of general anaesthetic action was first proposed by Emil Harless and Ernst von Bibra in 1847. [9] They suggested that general anaesthetics may act by dissolving in the fatty fraction of brain cells and removing fatty constituents from them, thus changing activity of brain cells and inducing anaesthesia.
To determine the depth of anesthesia, the anesthetist relies on a series of physical signs of the patient. In 1847, John Snow (1813–1858) [1] and Francis Plomley [2] attempted to describe various stages of general anesthesia, but Guedel in 1937 described a detailed system which was generally accepted.

Hua Tuo (華佗, ca. AD 145-220) was a Chinese surgeon of the 2nd century AD. According to the Records of Three Kingdoms (ca. AD 270) and the Book of the Later Han (ca. AD 430), Hua Tuo performed surgery under general anesthesia using a formula he had developed by mixing wine with a mixture of herbal extracts he called mafeisan (麻沸散). [5]
