286 INORGiNIC AGENTS 



3. Invert small animals, particularly with chloroform, 

 to allow blood to flow to the brain. 



4. Use forced, artificial respiration with bellows and 

 rubber tube introduced into larynx. Practice ordinary 

 artificial respiration in small animals by carrying the fore- 

 legs outward and forward till they meet in front of the 

 head, and then bring them back till they touch, and com- 

 press the sides of the chest. These movements should be re- 

 peated twenty times a minute. Artificial respiration may be 

 done in the horse by two persons compressing intermittently 

 one side of the chest with the knees and hands. Rhythm- 

 ical traction of the tongue, at intervals of five seconds, has 

 proved successful in restoring respiration. Dash hot or 

 cold water or ether upon the chest and epigastrium ; or use 

 the faradic battery to stimulate respiration by moving the 

 electrodes over the chest and abdomen. 



5. Give subcutaneous injections of strychnine and digi- 

 talis. Administer nitroglycerin on the tongue, or inhalation 

 of amyl nitrite. In chloroformization, give strychnine and 

 atropine hypodermatically ; and, in shock, saline infusion 

 as below. Do not use alcohol or ether as stimulants, for 

 their action resembles that of the anaesthetics. 



6. Use hot (115° F.), high, rectal injections of salt 

 solution (one teaspoonful to the quart) in case of surgical 

 shock with feeble pulse and subnormal temperature result- 

 ing from hemorrhage or other cause. Two to four quarts 

 for large animals, and one pint to one quart for smaller 

 animals. Saline infusion is still more efficient. (See " Saline 

 Infusion," p. 700.) 



CHOICE OF AN ANESTHETIC. 



Ether and chloroform are the only anaesthetics of any 

 importance in veterinary medicine. The A. C. E. mixture, 

 containing alcohol (one part), chloroform (two parts), and 

 ether (three parts), possesses no particular value, and is not 

 so safe as ether. While chloroform is inferior to ether in 

 the matter of safety, it may be given to horses by an
