The actual cautery or Paquelin's thermo-cautery is seldom employed to arrest hæmorrhage, but is frequently useful in preventing it, as, for example, in the removal of piles, or in opening the bowel in colostomy. It is used at a dull-red heat, which sears the divided ends of the vessel and so occludes the lumen. A bright-red or a white heat cuts the vessel across without occluding it.
That this inference is correct is shown by the fact that the application of a thermocautery to the intestines when completing a colostomy in a conscious patient is absolutely painless. One would conclude also that there are no touch receptors in the abdominal viscera, and therefore no sense of touch in the peritoneum.
Colostomy, an operation designed to make a fistulous opening in any portion of the rectum, was first practiced by Littre. In early times the mortality of inguinal colostomy was about five per cent, but has been gradually reduced until Konig reports 20 cases with only one death from peritonitis, and Cripps 26 cases with only one death.
