Chloroform or Ether?
The question of which is the best and safest general anaesthetic continues to be constantly brought under the notice of the profession by the frequent occurrence of deaths during anaesthesia. The fact that opinions are still so divided shows that a good deal can be said in favour of both chloroform and ether; but one thing stands out pre-eminently, and that is, that when deaths do occur they ar...
متن کاملEffects of Buffer Gas Composition on Autoignition of Dimethyl Ether
Experimental and numerical studies are conducted on the thermal, chemical and dilution effects of buffer gas composition on autoignition of dimethyl ether (DME). The buffer gases considered are nitrogen (N2), a mixture of N2 and argon (Ar) at a mole ratio of 50%/50% and a mixture of Ar and carbon dioxide (CO2) at a mole ratio of 61.2%/38.8%. Experiments are performed using a rapid compression m...
متن کاملThe Rohrig dropper device for ether or chloroform.
Practicing later as an eye-ear-nose-throat, or EENT, surgeon, John George Rohrig (1883–1933) received his medical doctorate from the University of Iowa in 1909. That same year, he reported his design for a dropper can (left) for ether or chloroform. The large-diameter screw cap allowed rapid reloading of the can with liquid anesthetic. A conical valve permitted finger-control of continuous drop...
متن کاملDevelopment of an Optical Gas Leak Sensor for Detecting Ethylene, Dimethyl Ether and Methane
In this paper, we present an approach to develop an optical gas leak sensor that can be used to measure ethylene, dimethyl ether, and methane. The sensor is designed based on the principles of IR absorption spectrum detection, and comprises two crossed elliptical surfaces with a folded reflection-type optical path. We first analyze the optical path and the use of this structure to design a mini...
متن کاملComparison of osteogenic potential of poly-ether-ether-ketone with titanium-coated poly-ether-ether-ketone and titanium-blended poly-ether-ether-ketone: An in vitro study
STATEMENT OF PROBLEM Poly-ether-ether-ketone (PEEK), a high-performance semi-crystalline thermoplastic polymer, has been employed to replace the metallic implant components in orthopedics. There were various studies performed in accordance to medical grade PEEK, but the relationship between titanium dioxide (TiO2)-coated PEEK, TiO2-blended PEEK, and untreated PEEK still remains complicated, eve...
