ACCIDENTS OF BLOOD-LETTING. 511 



is washed out with the tincture of iodine or perchloride of iron 

 solution, or even destroyed with the actual cautery. The last two 

 forms of treatment, however, are dangerous, from their liability 

 to occasion consecutive hemorrhages. 



3d Ilemorrhagie Phlebitis. — The most serious incident of 

 phlebitis, proceeding, as it does, from both the adhesive and the 

 sujjpui-ative forms, is the more or less abundant hemorrhage, 

 which, resulting from any of the various causes which have been 

 mentioned, may interfere with the cicatrization or obliteration of 

 the venous wound. Three modes of treatment are j^racticed for 

 their suppression. These are the twisted and the quilled sutiu'e, 

 and the ligation of the vein. 



{a) The Twisted Sutiire. — This consists in the combination of 

 several (two or three) long pin sutures, placed upon the wound 

 made by the fleam, and including a larger portion of the skin at 

 the sides than the single pin suture of an ordinary bleeding. 

 Sometunes wooden pins are substituted for those formed of me- 

 talHc material, and when the sutures are completed, the wound is 

 strengthened by a coating of some strong, adhesive mixture. 

 Some practitioners, however, prefer to this the application of a 

 severe blistering friction, which, by the pressure of the swelling 

 which it produces upon the internal circumjacent parts, secures 

 practically all the effects to be obtained by a compressive bandage. 



(b) Quilled Sutures. — These are applied on each side of the 

 wound, securing a good hold by placing them at some distance 

 from the edges, and embracing tightly between them a thick por- 

 tion of the skin. This point is important, for the reason that this 

 portion of skin is destined to be sacrificed by being left to slough 

 off, and this must not take place until the obhteration of the wound 

 is entii-ely completed. 



(c) Ligature of the Vehi. — The success of this operation, to be 

 assured, requires the selection of a healthy portion of the vein on 

 which to place the Hgature, even if it become necessary to look 

 for it among the original roots of the jugular, viz., the facial and the 

 glosso-facial. In performing it, the animal must be seciu:ed in the 

 recumbent position. A single incision is made through the skin, 

 the whole extent of the obliterated vein, jiarallel to its axis, and 

 the vessel exposed and sej^arated from the surrounding tissues. 

 The separation, which requires skillful and cautious manij)ulations, 

 can be effected by means of either a dii-ector or a long probe. It
