convenient and cheaper iiiikition of the udder witli air, whicli 

 promises far better results. 



Technique of the insufflation of air into the udder: The simplest form of 

 apijaratus consists of a hard rubber bulb eouuo.-ted with a hollow metal cyliuder cou- 

 taiuincr eottou wool, and an udder catheter or niilkiug tube fastened on the end of a 

 rubbed tube (in case of necessity a feather quill); it is sterilized by boding 

 in water and rinsing out with a one per cent creolin or lysol solution. Zehl 's double 

 iiir catheter (Fig. 116) appears especially useful. The udder is prepared for the 

 insufflation by milking out and thorough cleansing all four teats and the surrounding 

 parts with luke-warm water and a soft lirush. A clean piece of Inien soaked ma 

 •"; creolin or Ivsol solution is then ]ilaced under the udder and the teats and the 

 nei^hboriuo- ],arts are rinsed with creolin or ly^ol solution. Then the catheter or milk- 

 •" '^ ing tube is introduced into 



the canal of the teat and the 

 bulbs are V)rought into 

 play so that purified air is 

 passed through the cotton 

 wool into the udder. Suffi- 

 cient air must be intro- 

 duced so as to cause a plain 

 ly visible, tense, elastic 

 stretching of the udder. In 

 order to prevent the cathe- 

 ter from falling out, or the 

 infused air from returning, 

 the points of the teats must 

 be compressed with the dis- 

 infected fingers; the rub- 

 ber rings frequently em- 

 ployed appear to be less 

 adapted for the purpose 

 (Hess). At first the lower 

 quarters of the udder should 

 be inflated and afterwards 

 the upper ones. 



Kniisel uses 6-10 liters, 

 and Salvisberg 12-1.0 liters 

 of oxygen instead of air. 

 The oxygen is hehl in a 

 container, and after inser- 

 tion of a regulating appa- 

 ratus is allowed to pass 

 into the udder and the pro- 

 ceeding is repeated if neces- 

 sary; but this method of 

 treatment has no advantage 

 over that with atmospheric 

 air (Hess). — Formerly 

 some authors used salt or 

 lysol solution instead of pot. 

 iodide solution or ordinary 

 water boiled and allowed to 

 cool to body temperature, 

 up to 4 liters (Peters & 

 Wessel have each injected intravenously 2 liters of a 0.5% pot. iodide solution 

 warmed to 38° C, wliile others introduced this solution into the womb or gave it 

 internally). 



Since Schmidt's treatment has l)een employed tlie losses in 

 parturition paralysis have declined from 50 to 25 and even to 

 10% and often lower. This applies not only to the original 

 Schmidt treatment, Init to its various modifications without ref- 

 erence as to whether the pot. iodide is introduced in the food or 

 throui»h other organs, or whether, instead of pot. iodide, gaseous 

 sul)stances or other fluids are introduced into the udder.
