810 EPITOME OF MODERN TEEATMENT OF 



Poisoning. 



For Antidotes, see special drugs. Use of stomach tube most ef- 

 fective, 739. Emetics in dogs, cats and swine — mustard, 518; zinc 

 sulphate, 186; apomorphine, 373. Stimulants, as strychnine, 408, 

 camphor, 550. 



Poll Evil. See Abscess and Fistula. 



Polyuria. See Diabetes Insipidus. 



Post-Partum Hemorrhage. See Hemorrhage. 



Post-Partum Paralysis. See Apoplexy, Parturient. 



Prolapse of Rectum (In Cattle and Swine). 



If slight, of mucous membrane alone, apply ice cold water, and 

 astringents — as fluidextract of hamamelis — and replace bowel, after 

 washing and greasing it, and raising the hind quarters, or, if impos- 

 .sible to reduce, apply actual, cautery to prolapse in lines radiating 

 from its circumference to the center, and burn through the sphincter 

 in two places to aid its contraction after return of bowel. Intro- 

 duce morphine suppository, 356, or give it subcutaneously to pre- 

 vent straining. If all coats of bowel are prolapsed, as happens in 

 large prolapses, return bowel if possible, and then apply cautery in 

 lines parallel to long axis of the bowel — ^just within the anus^^-to 

 cause contraction there and prevent prolapse. Then apply pad over 

 anus, and give opium. In severe (old or gangrenous) prolapse of 

 great size, one must empty lower bowel by enema, push back any 

 loop of small intestine in the prolapsed portion and amputate the 

 prolapsed portion, performing an end to end anastomosis between 

 the two ends of the bowels. To prevent escape of the upper seg- 

 ment of bowel back into the belly, the two layers of bowel should 

 be fixed by two or three silk sutures placed just outside the anus, 

 before amputating. 



Prolapse of Uterus or Vagina. 



After cleansing and replacing parts, prevent recurrence of pro- 

 lapse by the use of opium, as above; elevation of hind quarters; 

 and by truss; West's vulval clamp; or closure of the vulva by wire 

 sutures of the quilled type.
