Stanislav Klikovich (1853-1910). Pioneer of nitrous oxide and oxygen analgesia

The career and work of Stanislav Klikovich (1853-1910) has been reviewed. He was born in Russian occupied Poland and was a pioneer of the use of analgesic concentrations of nitrous oxide in oxygen for many painful conditions including childbirth. He based his clinical work on sound research and animal and human experimentation and recognised that the analgesic state was distinct from anaesthesia.
