Hospital emergency rooms treat injured fingers all the time．Without treatment, a bad cut can lead to permanent damage．But how should a person know when a bleeding cut is serious enough to require medical attention?
Here are some tips from Dr．Martin Brown, chairman of the department of emergency at Inova Alexandria Hospital in Virginia．
1．Laceration （裂口）
The medical term for a cut or tear in the skin is a laceration．小题1:  A long cut on a finger can likely be treated without a visit to a doctor if the wound is not very deep．However, if you have a short but deep laceration, you will need professional attention,
2．Fingertips cut off
Some injuries, like a fingertip that gets cut off, might even need surgery （外科手术） to repair．小题2: More often, cutting down the bone is what is done because reattaching a fingertip is often not successful．
3．Bleeding
 小题3:  Small cuts usually produce what is known as venous （静脉的） bleeding．This means the blood flows steadily from the injury．The bleeding will often stop when pressure is put on the wound．In most cases holding direct pressure with a clean cloth for four to five minutes would do. But if a cut appears to be pumping blood out with some force, this may be a sign of arterial （动脉的） bleeding．__小题4:_
Finally, always keep this in mind: even a cut that does not require medical attention must be kept clean to prevent infection．Small cuts should be cleaned gently with clean water．_小题5:  Then cover it with a clean, dry bandage．

A．How a wound bleeds can be a sign of how serious it is．

B．That requires a specialist to either cut down the bone or reattach the fingertip．

C．This kind of injury should be treated by a medical professional as soon as possible

D．The first signs of this disease include difficulty opening the mouth．

E．Use a washcloth to clean the area if the wound is dirty．
F．With a cut finger, holding the hand above the heart can reduce the loss of blood．
G The length is usually not as important as the depth．
