OPERATIVE TECHNIQUE. 



or b}' pressure with warm sterilised compresses, en re l)ein<; taken 

 to avoid soilin^^ the peritoneum b}^ material escaping from the 

 incision ; the bowel must not be returned until it is certain that the 

 wound has been completely closed and the serous coats arouuLl the 

 suture touched with a strong carbolic solution in order to produce a 

 slight adhesive inflammation. For eight to ten days after operation 

 only small quantities of liquid nourishment, such as milk and beef- tea 

 for FTiiall animals and hay-tea for others, should be given. Ordii ar\' 

 food is then gradually resumed. 



In disinfecting the rectum, the food is diminished for se\eral da\s 

 in advance, and the same materials are prescribed as 

 tor intestinal antisepsis. In additi<m, however, the 

 rectum must be frequeiitK' irrigated. The anus is dis- 

 infected in precisely the same way as the healthy skin. 



The nasal cavities can Ije rendered aseptic by 

 washing out with sterilised lukewarm water, and afier- 

 waids by injecting a i in 5000 solution of sublimate or 

 a I in 1000 solution oi permanganate of potash. 



The e^e demands special precautions. It can be 

 1 allied with sterilised water, 4 per cent, boric solution, 

 1 in 150 or 200 creolin solution, or the following solu- 

 ti()n of biniodide of mercury recommended for man by 

 Pan as : 



Biniodide of mercury . 5 to 10 centigrammes. 

 Absolute alcohol . . ^o grammes. 



Boiled filtered water 1000 grammes. 



Sublimate must also be greatl}- diluted (i in 5000). 

 The instruments must be perfectl\- sterilised, especially 

 ||1^|| if the globe of the CN'e is to be opened. 



Disinfection of the external auditory meatus is 

 carried out with weak antiseptic solutions. The skin

 5000 sublimate solution. If discharge is abundant, the use oi bismuth, 

 salol, or iodoform is indicated. 



Antisepsis of the vagina is usually easy. Soap solution is used for 

 cleansing the mucous membrane, which is afterwards irrigated with 

 4 per cent, boric, 2 per cent, creolin, or i in 2000 sublimate solution. 

 These irrigations are repeated on several successue days. Instead 

 of syringes, irrigators consisting of a glas^ reservoir and an india- 

 rubber tube can be used. It is difficult howe\-er, to disinfect the
