The method to be adopted for this purpose will depend upon the size of the divided vessels. When these are small, the less the part is interfered with the better. A short period of exposure to cold air will usually suffice to stop the flow; should it fail, the edges of the wound may be brought together with gentle pressure, or the wounded surface may be irrigated with clean cold water, or pressed upon for a minute or two by a pad of clean lint or cotton-wool soaked in a solution of tincture of iodine in the proportions of 20 drops to the ounce of water.

When the haemorrhage is profuse, and the blood spurts out or flows away from certain points of the wound in distinct streams, the divided vessels must be sought for, and either twisted, or raised with forceps and tied round with aseptic gut or silk. It should be pointed out, however, that ligatures tend to retard the healing of wounds, and where possible should be dispensed with.
