The last time I regularly see people in the emergency department in which fingers stabbing devices where they do not belong. So I have several fingers amputated in recent months over ensue. Now I notice that the first question of the team’s hand, “the patient a smoker?”
Why this question? The reason for this question is that the chance of a successful re-implantation of the tip of a finger in smokers is virtually zero. It therefore not worth the effort or the cost to try.
The reason is that the blood supply to the fingers through the smoke before the crash so bad that after surgery the blood supply remains virtually absent.

The advice here is therefore twofold:
1. put your finger in places confused not hear
2. if you still smoke the fingertip then we can no longer … sorry ..
