Universal Precautions Needed For Treating a Wound

# data[].attributes.body
Use disposable gloves and other protective barriers while examining all patients and while handling needles, scalpels, and other sharp instruments. Washing hands and other skin surfaces that are contaminated with blood or body fluids immediately after a procedure or examination is needed. Changing gloves between patients and never reusing gloves is a must when treating wounds.

Puncture- a forceful injury caused by a sharp, pointed subject that penetrates the skin.

# data[].attributes.body
To care for a puncture wound, start off by stopping the bleeding; apply gentle pressure with a clean bandage or cloth. Clean the wound and apply an antibiotic such as Neosporin or Polysporin. Cover the wound and change the dressing whenever the bandage becomes wet or dirty.

After caring for a puncture wound, keep your wound clean and dry. When you are allowed to bathe, carefully wash the wound with soap and water. Dry the area and put on new, clean bandages as directed. Change your bandages when they get wet or dirty.

To care for a laceration, apply antibiotic ointment, and then cover the wound area with a sterile gauze bandage and first-aid tape. Clean the wound area daily with soap and water and apply a fresh sterile bandage.

After a laceration, take antibiotics and pain medication as directed. Avoid strenuous activities. Ask your doctor about when it is safe to shower, bathe, or soak in water. Do not pick at or scratch the wound.

Incision- a surgical cut made in skin or flesh.

# data[].attributes.body
To care for an incision, gently wash it with soap and water to remove the crust. Air-dry the incision or pat it dry with a clean, fresh towel before reapplying the dressing.

Post care treatment for an incision: a surgical incision heals in about two weeks. More complex surgical incisions will take longer to heal. If you have other medical conditions or are taking certain medications, your healing time may differ.

Avulsion- the action of pulling or tearing away.

# data[].attributes.body
To care for an avulsion, rest and ice the affected area and do controlled exercises that help restore range of motion. This helps improve muscle strength and promote bone healing.

Post care treatment for an avulsion includes cleaning the wound, elevating the wound, bandaging the wound, using cool compressions, and reducing scarring by avoiding direct sunlight on your wound.

Post care treatment that can be helpful to heal an abrasion includes cleaning the wound and changing the ointment and bandage once per day.
