Anaesthesia

The first classification system for general anaesthesia was proposed in 1847 by John Snow as the 5 stages of etherization (narcotism); and furthered by Francis Plomley in the Lancet in the same year. Guedel later proposed a four stage classification system to assess the depth of general anesthesia in 1937. This was designed for use with a single inhalational anesthetic agent (ether), in patients premedicated with morphine and atropine.
