These questions are worthy of study: How to select appropriate medical tape and using it correctly to avoiding skin lesion, and how to paste wound dressings on special sites so that the wound care dressing can be pasted securely, firmly and a long time lasting, which is not only convenient for patients to move and feel comfortable, but also conducive to wound healing.
Ⅰ. The fixation of new self-adhesive wound dressing
Closed or semi-closed wet dressings can maintain a constant temperature and humidity of the wound, which is conducive to wound healing. For example, if the dressing doesn't fall off or leak, it can last for 5 to 7 days normally. Although closed or semi-closed wet dressings generally have self-adhesive function, the adhesive at the edge of dressing will stick to the clothes and be easily lifted during patients using time, especially when the patient is uncooperative or irritable, the friction-prone parts are easy to loose, which affects the using time. In addition, the sacrococcygeal region and other parts are easy to be contaminated by urine and feces, which will shorten the using time and affect the treatment effect. Therefore, in order to prolong the using time of self-adhesive dressings and ensure the desired therapeutic effect of dressings, external fixation is necessary for self-adhesive dressings.
Methods: Wash and dry the wound and surrounding skin, paste hydrocolloid or foam dressing from the center of the wound, and then smooth the adhesive wound dressing on all sides by hand, try to avoid leaving gaps or wrinkles. The size of the dressing should exceed the outer edge of the wound at least 2-3 cm. In order to avoid the displacement of dressings in the area that is easy to rub while patients move, the edge of dressings should be fixed with a wide breathable tape or transparent film as a sealing edge. Paste on the sites easy to be contaminated by urine and feces, it can be covered with transparent film to avoid contamination. Mark the date on the outer dressing can clearly understand the using time of it. When changing dressings, we can hold the skin with one hand and then slowly remove the dressing from the corner of it to avoid damaging skin.
Ⅱ. Sticking skills of wound dressings for special sites
1. The aural region
For auricular skin injury, the self-adhesive dressing like foam dressing with adhesive border (hydrocolloid) can be cut into a size of 5*7 cm. After folding the length of wound dressing in half, short cut the dressing along the outer edge of its one side separated 0.5 cm. Usage: the uncut side of the dressing is fixed to the back of the auricle first, and then the side of the cut fragment is fixed homogeneously along the auricle shape. If the wound is moist, a small piece of alginate dressing can be placed at the bottom before sticking the self-adhesive dressing.
2. The armpits
Cut the foam dressing radially or cut it into a "ten" shape to increase the mobility and comfort. The axillary hair should be shaved before pasting the dressing to increase the adhesion effect.
3. The heels, elbows and other joint parts
Cut the wound care dressing, and overlapped paste the cut area slightly and make appropriate adjustment. We can use bandages to fix or put on socks for external fixation in order to prevent loosening.
