Use Wound Plaster Correctly to Protect Small Wounds from "Worsening"
# Correct Usage of Wound Plasters
In daily life, small wounds such as bumps, scratches, and abrasions are common. As the most common first-aid supplies, wound plasters have become a must-have for every household due to their convenience and ease of use. However, many people seem to know how to use wound plasters, but in fact, there are many misunderstandings. Incorrect use methods cannot protect the wound, but may also aggravate infection and delay healing. Today, we will detail the correct use method of wound plasters, teaching you to use this small tool correctly to protect wound health.
The core principle of using wound plasters is "cleaning, fitting, and timely replacement". The entire process is divided into four key steps, none of which can be skipped.
## Step 1: Clean and Disinfect to Build the First Line of Defense for Wound Protection
This is the most critical premise for using wound plasters and also the most easily overlooked step. If the dust and bacteria on the wound surface are not removed in time and the wound plaster is directly pasted, the bacteria will multiply in a closed environment, which is very likely to cause infection. The correct approach is: first rinse the wound with normal saline to wash away the surface dirt; if there is no normal saline, you can also rinse it with clean running water for at least 30 seconds; after rinsing, dip a sterile cotton swab in iodophor and gently wipe and disinfect from the center of the wound to the surrounding area. Be careful not to wipe back and forth to avoid bringing bacteria from the surrounding area to the wound; after disinfection, gently blot the moisture and iodophor on the wound surface with clean sterile gauze or cotton swabs, and wait for the wound surface to dry before proceeding to the next step.
It should be noted here that alcohol should not be used to disinfect deeper or larger abrasions. Alcohol is highly irritating, which will aggravate wound pain, and may also damage the normal skin tissue around the wound, affecting healing; do not directly wipe the wound with unclean paper towels or towels to avoid secondary pollution.
## Step 2: Choose the Right Wound Plaster and Fit It Precisely to the Wound
There are many types of wound plasters on the market, including ordinary type, waterproof type, breathable type, antibacterial type, etc. Different wounds are suitable for different types of wound plasters. Choosing the right style can better protect the wound. For ordinary small abrasions and scratches, a breathable wound plaster is sufficient to ensure that the wound can breathe and reduce stuffiness; for parts that are prone to getting wet such as hands and feet, choose a waterproof wound plaster, but note that the waterproof effect is limited, so try to avoid long-term immersion in water; for wounds with slight signs of infection or scenes that are prone to contact with bacteria, an antibacterial wound plaster can be selected to help inhibit bacterial growth.
After choosing the wound plaster, tear off the packaging. Be careful not to touch the absorbent pad in the middle of the wound plaster (i.e., the part that contacts the wound) with your hands to avoid bacterial contamination of the absorbent pad from your hands. Align the absorbent pad accurately with the center of the wound, gently press the adhesive tapes on both sides of the wound plaster to make it closely fit the skin surface, ensuring that the wound is completely covered without gaps. When fitting, pay attention to moderate force. Do not make it too tight, so as not to compress the blood vessels around the wound and affect blood circulation; do not make it too loose, otherwise the wound plaster will easily fall off and cannot play a protective role. If the wound is on a joint, an elastic wound plaster can be selected, which will not affect joint movement after fitting, and at the same time avoid the wound plaster falling off due to joint movement.
## Step 3: Replace Timely to Avoid Bacterial Growth
Wound plasters are not a one-time use item and need to be replaced regularly to ensure the protective effect. Many people are used to pasting the wound plaster until it falls off, which is incorrect. The absorbent pad of the wound plaster will absorb the pus, blood and secretions exuded from the wound. If it is not replaced for a long time, the absorbent pad will become damp and dirty, becoming a "hotbed" for bacterial growth, which is very likely to cause wound infection, with symptoms such as redness, swelling, pain and pus.
The correct replacement frequency is: replace ordinary wounds 1–2 times a day; if there is a lot of exudate from the wound and the absorbent pad is soaked, replace it in time to avoid the exudate flowing back to the wound; after using a waterproof wound plaster, if water is found or the absorbent pad is damp, it also needs to be replaced immediately. When replacing, gently tear off the wound plaster to avoid pulling the wound forcefully, clean and disinfect the wound again, and then replace it with a new wound plaster.
## Step 4: Master the Taboos – These Situations Are Not Suitable for Using Wound Plasters
Wound plasters are only suitable for superficial and minor wounds, not all wounds. In the following situations, wound plasters should not be used, otherwise the wound problem will be aggravated:
1. Deep and large wounds: When the wound is deep and bleeding a lot, the wound plaster cannot play a hemostatic and protective role. You should immediately press to stop bleeding with clean gauze, seek medical treatment in time, and suture and get a tetanus vaccine if necessary.
2. Infected and purulent wounds: When the wound has signs of infection such as redness, swelling, and pus, using a wound plaster will seal the wound, preventing the pus from draining and aggravating the infection. You should seek medical treatment in time and perform disinfection and drainage under the guidance of a doctor.
3. Wounds caused by rusty metal or unclean objects: Such wounds are prone to infection with tetanus bacilli and cannot be simply covered with a wound plaster. You should immediately rinse with clean water, disinfect, and then seek medical treatment in time to get a tetanus vaccine.
4. Ulcerated skin or eczema areas: The skin barrier of ulcerated skin or eczema areas is inherently damaged. Using a wound plaster will increase skin stuffiness and dampness, leading to worsening symptoms. You should use medication for care under the guidance of a doctor.
In addition, during the use of the wound plaster, pay attention to observing the changes of the wound. If symptoms such as redness, swelling, increased pain, pus, and fever appear on the wound, it indicates that infection may have occurred. You should immediately take off the wound plaster, stop using it, and seek medical treatment in time.
The small wound plaster, although simple, undertakes the important role of protecting the wound. Using wound plasters correctly can not only protect the wound and prevent infection, but also promote the rapid healing of the wound. It is hoped that everyone can master these use skills, and when encountering small wounds, handle them scientifically and protect them correctly, so that the small wounds can recover quickly without affecting daily life. At the same time, remember to regularly check the wound plasters at home and replace expired and damaged products in time to ensure that they can be used normally in case of first aid.
