          What, who, when?
• Anaesthetics – used to knock out the patient
  and prevent them from feeling pain. James
  Simpson used CHLOROFORM
  successfully for the first time in 1847.
• Antiseptics – used to kill germs and stop
  them from infecting wounds after
  operations. Joseph Lister used CARBOLIC
  ACID in 1867 in the form of a spray.

  Anaesthetics did not make surgery safer     Many surgeons simply did not believe
