Band-Aids are a common item in our little home medicine cabinet.

However, it is important to remember that Band-Aids are not a "cure-all".It has is only for small wounds that are more superficial, neat and clean wounds that do not bleed much and do not require sutures.

Don't use band-aids in the following situations：

1. Deep, narrow wounds, such as fingers and toes accidentally injured by nails, should not be bandaged. The wound should be left exposed after bleeding has stopped to prevent anaerobic bacteria such as tetanus from infecting the wound, and if necessary (e.g., cuts from rusty nails or knives), a tetanus shot should be given.

2. When the wound is not clean or there is a foreign body in the wound, a band-aid should not be used directly, but the wound should be cleaned or the foreign body should be removed before sterilization and bandaging.

3. Wounds caused by animal stings and bites are also contraindicated to avoid the accumulation or spread of poisonous sap and germs in the wound;

4. Wounds with large trauma should be treated in a regular hospital with sterilization, debridement, suturing and bandaging.

5.Heavily polluted, infected, bleeding wounds, heavier or wider skin abrasions, burns and scalds, as well as dermatologic wounds, etc., should not be used with Band-Aids.. (12)

Dr. Clove is here to answer that question.

On the instructions for the Band-Aid, we can see the words:

Used on small wounds, abrasions and other affected areas, it helps to prevent the invasion of bacteria and foreign bodies, maintain wound hygiene and prevent wound infection;

Special waterproof and bacteria-blocking function, which can effectively prevent infection caused by bacteria invading wounds in water and accelerate wound healing.

As you can see, Band-Aids are not 'all-purpose adhesive tape'.

1. The role of band-aids

It only serves as wound protection as follows:

• waterproofing
• antimicrobe
• foreign matter prevention

2. Wounds to which band-aids are applied

Band-Aids are only suitable for small wounds and, in this case, 'small wounds' must meet the following conditions:

• Neat wound.
• Not much bleeding.
• No stitches.
• superficial wound

3. Pre-use treatments

To effectively prevent infection, it is important to do the following before applying a band-aid:

• Rinse the wound well with clean water or saline.
• Make sure you've flushed the wound.
• Sterilized with povidone-iodine

Second, these times, can not use a band-aid

• Band-Aids should not be used for too long; they usually need to be changed daily, up to a maximum of two days.
• When replacing it, you should observe the wound, once the wound is red, swollen and suppurating you must stop using it and seek medical attention.
• Band-Aids should not be wrapped too tightly when used, as they tend to cause poor blood flow to the finger.
• In order to prevent the band-aid from coming off, there are rules for applying the band-aid on the finger area, so look at the picture and I'll leave it at that.

A final special reminder:Band-Aids are not recommended for children under two years of age due to the delicate skin muscles of infants and children, and bandages should not be too tight in any situation.

Bandaids are mainly used for superficial cuts, shallow wounds, new wounds, etc. and should be sterilized and replaced with a new band-aid every day! What if it is a bruise? Crush? A wound to a tendon or key? Do not use band-aids! Small cuts that can't control blood? You don't need stitches? You can use a Band-Aid to stop the bleeding? Within half an hour, loosen it up a bit to avoid necrosis of the finger! If you still can't stop the bleeding? Go to the local hospital to clean the wound and stop the bleeding! Thanks for the invitation!

Band-Aid so inconspicuous a medical supplies, improper use will actually happen so serious things, it is estimated that everyone has seen and used, as long as there is a wound the first time everyone will think of this thing. In the clinic have seen the use of band-aids after the emergence of allergies or redness and swelling, have not seen such serious consequences, let a person shocked.

Why did that girl have such serious consequences? First of all, it has to do with the wound cleaning, should be wound clean before use, otherwise after putting on the band-aid will lead to bacterial growth and infection. Secondly, it is also related to the tightness of the bandage, resulting in the blockage of blood circulation at the end of the finger, causing ischemia and necrosis, and finally can only amputate the limb. Therefore, we remind you that you should disinfect and remove foreign objects before use, and should not be too tight, not water, and change it frequently. Some allergic patients with severe allergy to adhesive tape can not be used.

Bandaids are not for everywhere and are not a "miracle cure". Bandaids are suitable for superficial and small wounds, less bleeding, and neat wounds. If the wound is deeper or need stitches can not be used. For septic wounds can not be directly with a band-aid to cover the past, which will help bacteria growth, increase septic infection. For wounds scratched by cats and dogs and other animals can not use band-aids, because as we all know, cat and dog scratches will have the risk of rabies, so you need to go to the hospital in time to inject the rabies vaccine, and then by the professional medical personnel to deal with the wound. If the wound is deeper after being stabbed by a very sharp and thin sharp object, it cannot be ignored and you need to go to the hospital for tetanus to avoid tetanus.

This thing reminds us not to ignore the little things and live scientifically. Seek medical attention if you are unwell.

Welcome to Apricot Island for more interesting health facts!

Thanks for the invitation! I don't need to rehash this as several of you have already answered it to the point above!

A few days ago, a friend accidentally scraped a large piece of the knee, I said that should be wiped with purple or iodine after exposure, to be healed by itself, the results of her fear of pain, do not allow the use of medication, to buy a band-aid ready to stick a thing. As a result, the next day, the wound site pus flow phenomenon, but after persuasion and timely use of iodine to wipe disinfection, after exposure to the wound two days that is healed and scabbed.

Band-Aids are not a cure-all

Now that I think about it, for the usage of band-aids, although it seems to be a very small thing, in fact, there are some misunderstandings in people's lives:

It is not suitable to be applied to abrasion wounds!

Instead, they should be sterilized with iodophor and other disinfectants, leaving the wound naturally exposed to the air for healing. This is because the abraded skin wound is larger than ordinary wounds, coupled with the poor absorbency and breathability of ordinary band-aid, not conducive to the drainage of wound secretions and pus, coupled with the sultry weather now, on the contrary, it will help the growth and reproduction of bacteria, easy to cause inflammation of the wound, or even lead to ulcers.

Small, deep wounds are not suitable for the patch!

Because small, deep wounds are not easy to clean, they are prone to foreign bodies and bacterial contamination, and are inherently prone to infection, especially anaerobic bacteria such as tetanus bacillus. If a band-aid is applied, the infection will be aggravated.

Animal bites are not suitable for posting!

Dog bites, cat scratches, snake bites and other wounds caused by animals should not use band-aids, so as to avoid the accumulation or spread of poisonous juice or viruses in the wound.

Burns and scalds are not suitable for the patch!

Wounds from burns and scalds, skin disease wounds, etc. should not be covered with Band-Aids!

After use, what to look for

1, band-aid is only suitable for superficial wounds, wounds neat, clean, bleeding less, without the need for stitches that can stop the bleeding of small wounds.

2, band-aid should be changed once a day; usually to keep dry, if soaked wet should be replaced immediately, otherwise it is easy to breed bacteria. 3, can not be wrapped too tightly, so as to avoid the wound is not breathable and anaerobic infections, or lead to the injured part of the blood circulation is impaired;

4, trauma without contact with foreign objects, it is best to remove the band-aid, so that the wound natural ventilation, can recover faster. Once the wound is found to be infected, it should be treated in the hospital immediately.

Also, popularize the difference between iodine and iodophor

Iodophor is an indeterminate conjugate of monomeric iodine with polyvinylpyrrolidone.

Iodine, also called tincture of iodine, is an alcoholic solution of iodine and potassium iodide. It penetrates the skin and kills bacteria (2-3% iodine is used as a skin disinfectant and 1% iodine is used to disinfect the oral mucosa).

As compared with iodine and alcohol, povidone-iodine causes less painful irritation and is easy to be accepted by patients, and is so versatile and effective that it has basically replaced alcohol, red mercury, iodine, violet drops and other skin and mucous membrane disinfectants. In addition, low-concentration povidone-iodine is a light brown solution that is not easy to contaminate clothing and has been widely used in hospitals.

The above was answered by Duan Lian, Deputy Chief Pharmacist, Department of Pharmacy, The Second Affiliated Hospital of Guangzhou Medical University, Guangdong Provincial Pharmaceutical Society, a dedicated volunteer of PSM Drug Shield.

Dr. Ping Ping answered this question.

Band-Aids may seem insignificant, yet improper use can have serious consequences! So, what are the wrong ways of applying a band-aid that can kill you? Poke the video and watch the doctor and JOJO demonstrate it for you! Next time never dare to operate like this!

I think it's a special case , the band-aid is used by everyone who is experienced with it.It feels like people are getting caught up in this band-aid use issue and not looking for deeper reasons.

I think the most immediate cause of the girl's amputation was an infection with a specific bacterium, gas gangrene, which is an anaerobic bacterium that causes muscle necrosis or myositis caused by Clostridium difficile. Post-traumatic complications of this disease can occur as early as 8 to 10 hours and as late as 5 to 6 days after the injury. If not promptly diagnosed and treated, the loss of limbs or life-threatening. It is spread through soil, droplets and direct contact. Early and thorough debridement, open wounds, anti-infection treatment. This bacterium, because it is anaerobic, accelerated the growth and reproduction of the bacteria after the surface of the wound was closed, resulting in serious consequences. And the biggest tragedy for this girl is the lack of awareness, if she could get to the hospital in time to clean the wound, the ending could be completely different.

This should require a little bit of common medical knowledge to protect yourself from such an unwarranted injury. For normal shallow superficial wounds, it is possible to use a band-aid to keep the wound from becoming contaminated and inflamed with pus. Larger wounds, on the other hand, require a trip to the hospital to treat the wound. If the wound is very deep and there is obviously a foreign body left inside the wound, it is even more important not to use a band-aid dressing! If some anaerobic bacteria invade through the wound, you can't help but put on the protection, is it not exactly what you want? Do not see where there is an emergency to the hospital to deal with wounds, if the wound is deeper, and then there is mud or other dirt contamination, the doctor will certainly expand the wound cleaning! He doesn't care if you're afraid of pain. Rinse the wound with hydrogen peroxide and dress it properly. Inject anti-tetanus vaccine or other antibiotics as appropriate.

There are some unique viruses that don't normally infect the human bloodstream, and tend to parasitize places like the soil. Once infected into the bloodstream is very dangerous. So where I do the above simple introduction, we must pay attention to, band-aid is not a miracle cure, can only protect some epidermal small abrasions, you can eliminate the trouble of wounds in contact with water only. Don't trivialize the usual small accidents.

A girl in Suzhou due to improper use of band-aids, wound deterioration and infection leading to amputation, which wounds can not use band-aids?

Q: "Why would the wound deteriorate leading to amputation?"

A: "One, the bandage was not sterilized before it was applied; and two, when the bandage was applied to the finger using a Band-Aid, it was applied too tightly, resulting in poor blood flow to the finger and causing necrosis of the finger, which children are generally unable to realize."

Q: "And what happens in the future if we are in a similar situation?"

A: "Nowadays, children are active, it is inevitable that there will be some small trauma, we generally do not recommend the use of band-aids for children, especially prohibited in children's fingers and toes, with band-aids for ring bandage. If a child has a small wound such as a broken skin, it is best for parents to bandage it with gauze, as gauze is more breathable than band-aids and is also conducive to wound healing. And while Band-Aids can be used on areas like the face, arms, and legs, again, be careful not to use a circular bandage."

Q: "Shouldn't that be sterilized with some red, purple solution?"

A: "Now has long been eliminated red and purple drops, if the child trauma wound shallow, you can apply a little povidone-iodine, it will be fine, if the wound is deeper, it is still recommended to go to the hospital, by the doctor to carry out professional disinfection treatment for the better."

The Proper Use of Band-Aids

How often to change band-aids

Although Band-Aids are convenient and can stop bleeding and protect some small wounds, they are not foolproof and should not be used for a long time. If the wound is not breathable, not properly treated, and has not been replaced, but will aggravate the deterioration of the wound. Therefore, the band-aid should be changed at least once a day to avoid the pores of the skin being blocked for a long time, resulting in poor ventilation of the local skin, leading to discomfort.

After the use of band-aid need to pay attention to observe the changes in the wound, and should be changed regularly, so that can be very good is to prevent the wound from becoming infected with pus.

If the band-aid has been on for more than 24 hours and the pain in the wound worsens, or there is even secretion oozing out, you need to open the wound and check it in time. If the wound is found to be red, swollen, oozing and some other infected phenomena, we must immediately stop using band-aids, and promptly go to the hospital for treatment.

What to do if the band-aid won't come off

In life, sometimes it is inevitable that some bumps and bruises of small accidents will lead to small wounds, this time to put on a band-aid can be an emergency to stop bleeding, very convenient. But it will also happen that the band-aid and flesh adhesion, tear down the situation, tough tear down the pain is unbearable, but also may hurt the wound, here, I organized some band-aid tear down when you can do the tips:

1. Wet the band-aid with warm water or apply a hot towel to the band-aid for a few moments and then gently tear it off;

2, to tear the band-aid down as far as possible, do not lift the band-aid too high, so that it is as far as possible to lean into the bottom, slowly tear down, can reduce pain;

3. Wet the band-aid with hydrogen peroxide disinfectant, but don't get it on top of the wound, or it may cause pain.
