DYSPNOEA FROM LARYNGEAL HEMIPLEGIA IN THE HORSE.

the ventricle. This will in a few minutes produce both anesthesia 
and anemia in the walls of the ventricle. Next place upon the 
index finger the “ thimble curette ” and pass it into the ventricle, 
and by a little gentle scraping lacerate and destroy the thin 
mucous membrane lining. It is entirely unnecessary to be rough 
here, but, of course, the mucous lining must be thoroughly 
scraped. This curetting ends the operation. As after-treat¬ 
ment, little is necessary, but antiseptic attention will, of course, 
facilitate healing. In some cases an oedema of the glottis de¬ 
velops, and all patients must, therefore, be seen every few hours 
for the first three or four days. Upon the appearance of dyspnoea 
a laryngeal breathing tube should be inserted through the crico¬ 
thyroid incision. This tube is not needed in every case, and it 
should only be used when dyspnoea exists. But to be on the safe 
side, the tube should be kept in during the first three or four 
nights. 
Now this operation can be performed by any veterinarian. 
It is one of the simplest operations in veterinary surgery. Of 
course, the merest novice in surgery can cut through the skin and 
crico-thyroid membrane, and anyone can then introduce the finger

and pass it into the lateral ventricle. This is as simple as passing 
the finger into one’s vest pocket. Nor is any skill recpfired to 
curette the mucous lining of the ventricle. 
It is not necessary to cast the patient in performing this oper¬ 
ation; in fact, it can be done easier with the patient on its feet. 
No assistants are needed. A check-rein will hold the head up. 
With good cocaine and adrenalin in solution, the operation can 
be performed painlessly and bloodlessly, and it should not take 
over three or four minutes to perform it. 
In those rare casese where the paralysis is bilateral the mucous
