BLOOD VESSELS, NERVES AND TENDONS
Assess the function of tendons, nerves and blood vessels distal to the laceration. Ligate lacerated vessels whether or not they are bleeding, as the vessels which are not bleeding may do so at a later time. Large damaged vessels may need to be divided between ligatures. Before dividing these larger vessels or an end artery, test the effect on the distal circulation by temporary occlusion of the vessel.

Loosely oppose the ends of divided nerves by inserting one or two sutures through the nerve sheath. Similarly fix tendon ends to prevent retraction. These sutures should be long enough to assist in tendon or nerve identification at a subsequent procedure. Formal repair of nerves and flexor tendons is not urgent and is best undertaken later by a qualified surgeon.
