Best Of How To: Stop Scalp Bleeding

Bleeding from scalp wounds may seem like a trivial problem, but I have personally seen someone die from unrecognized hemorrhage over time from one. All too often, these are covered up with a crude dressing when the patient arrives in the ED and is not looked at for some time.

Here are some tips to stop scalp bleeding:

  • Use direct pressure. This seems obvious but is frequently done incorrectly. Direct pressure involves a small diameter piece of gauze (stack of 2x2s or double folded 4×4) and only one or two fingers. Larger dressings or the palm of the hand do not provide enough pressure to stop all the bleeding. Direct pressure for 5 minutes (no peeking) will stop all bleeding that doesn’t need more advanced techniques.
  • Inject local anesthetic with epinephrine. This increases vasoconstriction and helps the direct pressure work even better. Be cautious if there is a large skin flap that does not have a nice pink color. Degloved skin has been crushed and small vessel vascular injury has occurred. Further reducing blood flow with epinephrine may kill the skin flap in this type of injury.
  • Apply Raney clips. Neurosurgeons use these to stop scalp bleeding during brain procedures. Caution! Only apply to unconscious patients, and only to the scalp (not face)! These hurt!

  • Oversew the scalp. Use a large silk or nylon suture and insert a large running stitch to close the wound. This will stop all bleeding from the skin edges. However, any arterial bleeders underneath will continue to be a problem.
  • Ligate individual bleeders. Use a small absorbable suture and attack each small arterial bleeder with a figure of 8 stitch. Don’t suture large chunks of tissue; make sure that you are attacking just the artery and not any adjacent nerves.
