166 DEPRESSANTS TO CENTRAL NERVOUS SYSTEM 



and is therefore more liable to increase bronchitis in those already 

 suffering with it. 



5. Ether is more liable to irritate the kidneys and those suffering 

 with the various forms of acute or chronic renal disease or even renal 

 insufficiency should be subjected to ether anesthesia only when it is 

 administered with great caution. 



6. Ether never produces sudden reflex stimulation of the vagus 

 and death in the early stages of anesthesia except in the cat. 



7. In ether the period of excitation is much prolonged and con- 

 sequently there is more struggling. 



8. It must be given much more concentrated than chloroform. 



9. Since it is inflammable it must not be used around an open 

 flame. 



10. Ether is the more generally used in the United States in 

 human medicine and is to be preferred for small animals.

A. C. E. MIXTURE 



Many mixtures of chloroform, ether and alcohol have been advo- 

 cated to combine somewhat the strong anesthetic action of chloroform 

 with the less dangerous drug, ether. Of these mixtures probably the 

 above holds first rank. It is composed of alcohol one part, chloro- 

 form two parts and ether three parts, by weight. 



Hobday states that for young puppies and cats this is a better 

 anesthetic than either chloroform or ether alone, and he prefers giv- 

 ing it to these animals by means of a special inhaler, in which the 

 gas is forced out of a bottle holding the mixture. Various other pro- 

 portions of these agents have been advocated by different authori- 

 ties.
