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 HabiHty 

 to occasion consecutive hemorrhages. 



3d Hemorrhagic Phlebitis—lhe most serious incident of 

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

 suppurative forms, is the more or less abundant hemorrhage, 

 which, resultiag 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 practiced for 

 their suppression. These are the twisted and the quUled suture, 

 and the ligation of the vein. 



(a) The Twisted /Suture. — This consists ia 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 pia suture of an ordinary bleeding. 

 Sometimes wooden pins are substituted for those formed of me- 

 talHo 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 sweUing 

 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 apphed 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 obliteration of the wound 

 is entirely completed. 



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

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

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

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

 glosso-f acial. In performing it, the animal must be secured in the 

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

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

 the vessel exposed and separated from the surrounding tissues. 

 The separation, which requires skillful and cautious manipulations, 

 can be effected by means of either a director or a long probe. It
