174 SYNOPSIS OF VETERINARY 



stronger than 9 per cent are not stable and will separate crystals 

 of eucaine. 



Solutions of eucaine less than 9 per cent do not decompose 

 and may be sterilized (boiled) without suffering deterioration. 



Actions and Uses. — This drug has the same physiological 

 actions and uses that Cocaine has ; its advantages over cocaine 

 lie in the fact that it is far less poisonous. ( | as toxic as co- 

 caine,) and solutions of eucaine are permanent and do not, .like 

 those of cocaine, decompose when kept ; again, solutions of eu- 

 caine can be boiled for the purpose of sterilization, whereas so- 

 lutions of cocaine are decomposed by this process. 



It is used in solutions varying from 1 per cent up to 9 per 

 cent. For dogs usually a 2 per cent and for horses a 5 per cent 

 solution is used. 



A few drops ( 10 to 20) being enough to paralyze a large 

 nerve trunk, (the metacarpal nerve for instance X. 



It is said to have more powerful anaesthetic effects than co- 

 caine. The writer's experience is to the contrary, a longer period 

 must be allowed for it to begin its action (10 to 15 minutes). 



It may be incorporated in salves, powders lotions, etc., in 

 the same way that cocaine has heretofore been used. 



It can be carried conveniently in solution, say a 5 per cent 

 solution, make this by adding 15 grains of eucaine to 5 drachms 

 of distilled water, this can be boiled before using and thus it is 

 not necessary to add antiseptics to the solution, for the purpose 

 of preserving it.
