Research Facts
Liquified phenol is made from liquified carbolic acid by the addition of 10% water, is poisonous and its anesthetic qualities will numb rather than burn skin. Phenol (C6H5OH) has a distinct odour that is sickenly sweet and tarry. A colourless liquid when pure, otherwise pink or red. Commercial phenol is a liquid that evaporates more slowly than water. Pharmacy bottles were designed with built in hazardous warnings by adding raised vertical grooves, or embossed stars when the contents were poisonous. The tactile reminder eliminated possible improper use, especially in poor lighting for the customer. Dr Ralph and Mrs Olga Crawford donated their extensive Canadian dental collection to the DCF to create the museum in 1997; further donations were received while Dr Crawford was Curator Emeritus at the Dental Canada Museum until its closure in 2008.

Research Facts
Dr Ralph and Mrs Olga Crawford donated their extensive Canadian dental collection to the DCF to create the museum in 1997; further donations were received while Dr Crawford was Curator Emeritus at the Dental Canada Museum until its closure in 2008; this item was donated by Dr. Norman Ironstone from Ottawa, Ontario; Somnoform was a general anaesthetic made from 60 parts ethyl chloride, 35 parts methyl chloride, and 5 parts ethyl bromide; it was invented by Georges Rolland, director of the dental school at Bordeaux, in 1901; the anaesthetic had a very low boiling point, and turned to gas immediately upon contact with air; it had to be used with a special inhaler or, originally, with a piece of cloth with paper and cotton batting inside; one of its virtues was the fact that a patients breathing stopped before their heart stopped beating, so dentists could monitor their patients breathing in case of problems; it was claimed to be better for minor surgery than nitrous oxide because of its longer anaesthetic time, and better to use before ether or chloroform; while the instructions claimed it was the safest of all anaesthetics, a few deaths did occur, and its use was fairly short-lived

https://en.wikipedia.org/wiki/Cyclopropane https://www.britannica.com/science/cyclopropane
Research Facts
Cyclopropane is an anaesthetic when inhaled. In modern anaesthetic practice, it has been superseded by other agents, due to its extreme reactivity under normal conditions: when the gas is mixed with oxygen, there is a significant risk of explosion. Cyclopropane had no commercial application until Henderson and Lucas discovered its anaesthetic properties in 1929; industrial production had begun by 1936. This meant induction of anaesthesia by inhalation of cyclopropane and oxygen was rapid and not unpleasant. However at the conclusion of prolonged anaesthesia patients could suffer a sudden decrease in blood pressure, potentially leading to cardiac dysrhythmia; a reaction known as "cyclopropane shock".For this reason, as well as its high cost and its explosive nature, it was latterly used only for the induction of anaesthesia, and has not been available for clinical use since the mid 1980s. Cylinders and flow meters were coloured orange. Cyclopropane, also called trimethylene, explosive, colourless gas used in medicine since 1934 as a general anesthetic. Cyclopropane is nonirritating to mucous membranes and does not depress respiration. Induction of and emergence from cyclopropane anesthesia are usually rapid and smooth. A mixture of about 5 to 20 percent cyclopropane in oxygen is administered by inhalation. Because of the flammability and expense of cyclopropane, it is usually used in a closed (rebreathing) system, in which an absorbent chemical, such as soda lime, removes exhaled carbon dioxide, and the anesthetic is recirculated. The chemical formula is C3H6.
