Precautions when taking care of wounds

Controlling external bleeding

  • There are 3 different ways to control bleeding such as: Direct, elevation, and pressure points.
  • With direct you want to put pressure on the wound with gauze and if the bleeding goes through, add more gauze!
  • Next you'll want to elevate above the heart (if possible) and continue with the pressure
  • Lastly apply pressure to an artery to decrease the blood flow to the area.
  1. You can apply pressure to the Brachial artery- upper arm
  2. Or apply pressure to the Femoral artery- top of thigh

Wound care

For immediate care you would use Universal precautions - to treat all wounds as if they've been contaminated with blood borne pathogens.

  1. First step: To ALWAYS wear gloves
  2. Clean wounds with soap, water and sterile solution
Antibacterial ointments are effective in limiting bacterial growth and preventing wound from sticking to dressing

When are suture (stitches) necessary?

  • Deep lacerations, incisions, and occasionally punctures
  • If wound edges, it may be needed
  • Cannot be easily pushed back together
  • A physician should make the decisions
  • Within 12 years, sutures can then be used
  • If stitches are not required, you can then use steri-strips
