Injuries — fingernails and toenails

Attention

  • Always better to keep nail in place if possible. Can be used to splint injury by taping back onto nail bed
  • Try not to damage nail base, so nail will grow back evenly
  • If diabetes — medical consult before proceeding

Letting out blood from under nail (subungual haematoma)

Attention

  • Use if blood is not clotted (fluid) and covers only part of area under nail
  • If blood fills whole area underneath nail — nail may need to be removed, or lifted to suture underneath
  • Hot end of needle or paperclip should go just under nail surface and not touch nail bed. Painless if done properly
  • Tell person discoloured part of nail will usually grow out over 4–6 months. If enough of nail bed injured — nail will drop off, new nail grows in over 4–6 months

What you need

  • 19-21G needle
    • OR ordinary paperclip and hot flame source (eg lighter, candle, spirit lamp)
  • Sterile dressing pack
  • Normal saline
  • Sterile gloves
  • Dressing, if needed

What you do

  • Wash hands and put on sterile gloves
  • Pierce nail — use gentle rotating motion with needle to make 1 or 2 holes in nail
  • OR as per local health guidelines — unfold 1 end of paperclip and hold over flame until red hot — Figure 7.15
    • Quickly move paperclip to nail. Hold at 90° (right angle) and press down lightly into haematoma (centre of blood)
    • Don’t push too hard, let paperclip burn through nail. You will feel it give way, blood will ooze out, pain will lessen — Figure 7.16
