COLIC DUE TO INGESTION OF COLD WATER— CONGESTIVE COLIC. 163 



animals show uneasiness, stamp, and continually move about striking 

 themselves m the flank with the feet or horns, swishing the tail, etc. 

 They refuse food, lie down and rise frequently, and paw the ground. 



As a general rule this form of colic lasts from half an hour to one 

 hour, and terminates in recovery. In some rare cases where death 

 occurred C'ruzel found on post-mortem examination congestion of the 

 abomasum, and, in a few, congestion of the small intestine, with or 

 without rupture. 



The diagnosis is easy, on account of the suddenness of onset, rapid 

 development and history of the disease, discovered on questioning the 

 owner or herdsman. 



The prognosis is not grave. This form of colic generally cures itself. 

 Nevertheless precautions are required against possible compHcations, 

 such as intestinal haemorrhage and invagination. 



The necessary preventive measures are self-evident. Animals return- 

 ing from work should not be allowed to drink freely of cold water, but 

 should first receive a little food and afterwards water at the temperature 

 of the atmosphere. 



When colic has set in, the patient can be walked about. If pain 

 persists, the region of the abdomen may be dressed with oil of turpen- 

 tine, mustard, or similar counter-irritants. The application of warm 

 clothing is also useful. Finally, in grave cases, a moderate quantity 

 (three, four, or five quarts) of blood maybe withdrawn from the jugular. 

 The administration of stimulants like wine, alcohol, etc., is also 

 indicated. 



COLIC DUE TO INVAGINATION. 



Invagination consists in the passage of one portion of the intestine 

 into the next-following portion. When once the condition has been set 

 up it tends to become aggravated, the invaginated part being drawn 

 further and further forwards. Invaginations therefore may vary in 

 length between a few inches and sixteen to twenty inches. 



Law states (Vol. II. p. 347) that in cattle and swine invagination of 

 the large colon is almost impossible owing to the relation of the bowel 

 with the layers of the mesentery. The anatomical arrangement is 

 Ojpposed to the formation of invagination, yet this accident is not 

 uncommon in cattle and swine. The small intestine can be invaginated 

 into the caecum or into itself. The csecum may become invaginated, or 

 it may pass into the colon or rectum. 



Cartwright, Vcteri7iarian (1829), reports a case of invagination in 

 a bull calf, and Youatt gives particulars of a similar case which was 

 followed by sloughing and discharge per anum of the intussuscepted 

 portion of bowel. (See also Moller and Dollar's " Eegional Surgery," 



p. 328.)
