In many cases, likewise, of alarming hemorrhage from wounds in specially difficultregions, perfect and immediate cessation of the bleeding can be obtained by passing the pin throughthe sound skin and below the track of the wounded vessel or vessels, and causing it to emergeat a suitable distance so as to allow a ligature to be thrown around the point and head of thepin, thereby firmly but not too tightly compressing the tissues together and holding them ina grip that can be regulated by slackening or tightening the ligature. These pins can be usedover and over again, and kept aseptic by boiling after use. This little instrument may some-times be of special service to surgeons accompanying troops into action, or in a field hospitalwhere work is done under pressure due to want of 620 a:\ierican practice of surgery. Pressure; Ligation.—This is the most generally used and safest method forthe permanent arrest of hemorrhage from any but the smaller vessels. It issafe and effective when reliable material is used, pro^ided the hgature is properlyapphed. The materials generally used for hgatures are catgut and silk—ordi-nary aseptic catgut for the small vessels, and for the largeones either silk or catgut which has been rendered less absorb-able by chromic acid or other means. The bleeding vessel iscaught with haemostatic forceps or a tenaculum and drawnslightly out of its sheath, and the ligature is then applied ashort chstance from the end and carefully tied by a surgeonsknot or reef knot (Fig. 189), and the ends of the ligature cutshort. It was formerly taught that the pressure should justKnot orRerf^Knrt. ^^ Sufficient to cUvide the inner coat of the vessel, but to-dayit i
