Basic principles in effective wound care should be known

Wound assessment

  • The wound will be assessed by the doctor, judging that if the wound edge is flat, the healing process is fast, but if the wound has a rough edge, it is likely that the two edges of the wound will be difficult to close. .
  • New wounds will have better healing progress than old wounds, wounds are also accompanied by other injuries, making the wound more susceptible to infection, reducing resistance and prolonging wound time. heal again.
  • Where the wound is located on the patient’s body is also very important because there are areas with a lot of blood, clean areas, low chances of infection and more blood supply, the healing time will be shortened. much more.
  • Good health also contributes to the healing of wounds, and people who are obese or malnourished will also greatly affect their ability to heal. Patients with other comorbidities such as diabetes, cancer, tuberculosis are at risk of suturing and wound healing will be slow.

Wound care

  • Remove foreign bodies and bruises: any wound has the presence of bacteria, so removing the bruised tissue, removing the hematoma, foreign body will cut off the source. provide food for bacteria. Always keep the wound in a sterile state, avoid bringing in new bacteria.
  • Expand the wound with good drainage : the stagnation of fluids, old blood, foreign bodies, etc. is a food source for bacteria. Fluid stasis reduces the wound tissue’s ability to proliferate granulomatous tissue. Therefore, it is necessary to drain the fluid very well to stimulate the growth of granulation tissue to accelerate the wound healing process.
  • Helps wounds heal :
    • Every wound has a natural protective barrier, so when taking care of the wound, we should not destroy that barrier by: avoiding hurting the surrounding areas in the wound, not touching the wound much. love; Changing the dressing regularly every day is not technically correct.
    • Using an appropriate antiseptic solution is a protective barrier to prevent bacteria from entering, but it will also have the risk of injuring the granulomatous tissues, so do not use an antiseptic solution to apply directly to the wound if there is no suture. doctor’s decision.
    • The wound will always exude fluid, so keeping the wound moist is essential, but not too wet, so it is necessary to change the dressing when it is wet.

Wound care

Wound dressing:

  • A wound covered with a bandage will create a suitable environment for the wound healing process because the bandage absorbs fluid well, protecting the wound from impact and further damage.
  • When the wound is covered with a bandage, it will also help protect the wound from being attacked by dirt, bacteria, and foreign objects.
  • At the same time, dressing the wound also helps to stop bleeding when applying pressure or when splinting immobilize the wound. Dressing the wound will give the patient a sense of peace of mind.
  • New dressing is considered a form of preventing new tissue from growing deep into the old dressing, when removing the dressing can create a new wound on the newly formed granulation tissue.
  • A wound that is too wet / too dry will both slow down the healing process so dressing the wound will help maintain the right moisture on the surface of the wound.

No wound dressing:

  • Not dressing the wound also has significant benefits for the wound as it helps to eliminate the favorable conditions for bacterial growth (wet, warm, dark). With a wound without a bandage will help us observe and monitor the progress of the condition easily, bathing is also more convenient.
  • When removing the bandage improperly, there is also the risk of creating more injuries for the patient. So, not changing the bandage will also avoid additional damage, avoid adhesive tape allergies and save bandages, solutions …

Wound cleaning technique:

  • Wash the wound in a straight line going from top to bottom and wash from the inside out, from the cut in a straight line running parallel to the wound.
  • Always start washing from clean to less clean areas and use a cotton swab/gauze for each wipe in the downward direction.
  • It is recommended to use safe, benign solutions that do not harm body tissues so as not to interfere with the wound healing process. The gauze used can be synthetic or cotton (cotton is more commonly used because it has large crevices, they will retain moisture and are suitable for the wound).

Pay attention when taking care of the wound

  • Follow the correct order of wound care.
  • To apply a new dressing over the wound: Place the gauze gently in the center of the wound, extending it to the sides at least about 2.5cm from the edge of the wound.
  • For wounds that are oozing a lot of fluid, an absorbent gauze dressing has several layers above the gauze, 2-3 layers can be applied to absorb fluid until the next layer of dressing is changed.
  • Once the dressing is in place, secure the edge of the gauze to the patient’s skin with duct tape or possibly secure with a knot, elastic bandage, for maximum patient comfort.
