REBEL Core Cast – Basics of EM – Lacerations

Take Home Points

  • Don’t make bite width to small – look at the curvature of the needle – start the bite at half the curvature of the needle
  • Don’t pull too tight – this will pucker the skin and lead to poor healing due to ischemia at the wound borders
  • Laceration repairs are not sterile! Does not lower infection rates
  • Pressure irrigation DOES decrease infection rates – irrigation is the solution to pollution
  • Avoid lido with epinephrine for tips of fingers, nose, ears, and genitals
  • Splint or apply bulky dressing to large lacs that cross joints
  • Very long lacs when cosmesis doesn’t matter – consider using staples
  • Avoid sun exposure after laceration repair – leads to worsening scar formation
