Before thinking about healing a wound at home, you first have to see its characteristics. Let’s take a look!

How to prevent a wound from becoming infected

first, it’s important to assess whether the wound is large or deep enough to require medical attention. If so, expert help immediately. It’s also always important that the best cure is prevention.

That said, we’ll give you some tips to prevent a wound from becoming infected at home and thus help it heal.

Stop the bleeding

To begin with, when treating a wound, you should wash your hands thoroughly with soap and water. This will prevent the spread of germs or bacteria to the person who is injured.

Your wounds take time to heal

Use a clean cloth, rag, or cloth to gently press down on the affected area. Pressure helps the blood clotting process. The ideal time to apply pressure is between 20 and 30 minutes.

On the other hand, to prevent bleeding in the extremities, it’s recommended to elevate the injured body part above the heart:

  • The arms or hands can be held in the air or placed on a surface that is higher than the chest.
  • The legs or feet can be elevated on a pile of pillows (for example).

Clean to prevent a wound from becoming infected

Cold water is ideal. This will drag particles of sand, dirt, or any trace of dirt that can cause an infection. The skin around the wound should be washed with soap and water and then dried with a towel.

  • If any particles remain in the wound, they should be carefully removed. Do this with eyebrow tweezers that have been previously sterilized with alcohol.
  • Large particles or embedded objects must be removed by a healthcare specialist. By doing it at home, you may just inflict more damage.
  • Avoid the use of alcohol. This is because it can cause irritation and delay the healing process. It’s also not advisable to clean the wounds with cotton balls, as this material leaves behind a residue.

Apply topical antibiotics and cover the wound

There are creams and ointments with different active ingredients to clean wounds on the market. The function of these creams is to prevent infection, not to speed up the recovery process.

Remove the bandage from a bleeding wound

Overall, this is the most effective way to prevent the wound from becoming infected. If the wound is small, an adhesive bandage can be used.

Apply a bandage

  • Those allergic to the glue in bandages can opt for gauze and adhesive bandages. Also, there are hypoallergenic options on the market.
  • When bandaging, it’s not necessary to tighten too much. Applying too much pressure with the bandage can obstruct circulation.
  • The bandage should be changed daily until the wound heals. If it gets dirty or wet, it’s also advisable to replace it.
  • Finally, remember to avoid the temptation to remove the bandage constantly to see if the wound is healing.

Keep an eye on the wound

All the necessary steps are followed to prevent a wound from becoming infected. However, it’s best to remain alert and observe its evolution. If any of the following symptoms occur, you have likely become infected. In any of these cases, it’s best to seek help.

Seek professional help if the wound:

  • Does not heal.
  • Hurts more.
  • Turns red.
  • Forms boils.
  • Presents pus-like secretions.
  • Feels “hot.”
  • Causes a fever.
