Whether it’s an emergency or not depends on how long, how deep, and where the cut is located. The good news is that finger cuts are seldom life-threatening.
With finger cuts, the biggest concern is that you could lose finger function or even the entire finger. However, more severe cuts or amputated fingers do have the potential to be deadly. That’s because a deep gash across the palm or cutting off multiple fingers could lead to significant blood loss.
You most likely are not going to die from a finger laceration, but you want to move quickly to ensure the survival of the finger.
If the bleeding is severe (not just oozing) or blood is squirting, immediately take steps to control bleeding and call 911. Also, if you’ve cut off any part of a finger, call 911. Both of those are real emergencies.
