Cyclopropane CylinderAbout this object
Cyclopropane was originally thought to be the toxic compound within propylene
from which it was isolated by George Lucas in 1927, working with Professor V. Henderson and W.E. Brown in Toronto, Canada. It was, however, the anaesthetic.
‘Cyclo’ was first used clinically by Ralph Waters in Wisconsin in 1930 and was introduced in Australia by Gilbert Troup in 1935. It had numerous benefits over ether, chloroform and nitrous oxide and so became the favoured agent of many
Cyclopropane was used with a high percentage of oxygen, which was of
advantage to patients. Its high cost was a blessing in disguise by helping to lead to the introduction by Ralph Waters of ‘controlled’ (by inducing hypocapnia) respiration in anaesthesia and the gas could be used in a closed circuit with little wastage. Its disadvantage was its flammability - an issue that could (and did on occasions) prove lethal to both patients and theatre staff.
Cyclopropane and others were replaced by Halothane in the 1950s.
