How Long to Leave Bandage on Wound?

Most people expose their wounds to the air to breathe. However, this is a mistake since it produces a dry environment which encourages cells to die. It’s not beneficial to air out your wounds because wounds require moisture to heal properly. Not covering your wound may result in drying out of new surface cells which can potentially slow down the healing process.

Many wound coverings such as bandages promote a slightly moist wound surface. This can keep the new skin and other cells alive. Additionally, it can aid in protecting the area from germs, dirt, and additional injury. Covering your wound instead of leaving it open may also make you feel more at ease and comfortable. 

However, as with a lot of medicines, there are some exceptions to the rule. You can leave small dry scabs from scrapes and minor cuts uncovered. Similarly, you can leave pressure ulcers on your heels open to dry. But if you think your wound looks a bit deep and not healing or getting an infection, let a medical professional examine it right away.

So how long to leave a bandage on the wound? You should leave a bandage on for 24 to 48 hours for most minor wounds. This gives enough time for most minor wounds to heal fully.

For bigger or more serious wounds, you will need to keep the bandage on for longer, around 3 to 5 days. You should see a doctor anyways for more serious wounds so the doctor will advise you how long you should leave the bandage on for.

I emailed Dr. Heather A. Brandling-Bennett, a dermatologist at Seattle Children’s Hospital, and asked her how long to leave a bandage on a wound. She said, “1 to 2 days should be sufficient for a minor wound to heal itself.” She also said, “If the wound is more serious, then you should see a doctor to get the recommended duration.”

Types of Bandages and How Long Each Should Be Left on For

A bandage is a type of textile wound dressing for covering up a wound until its healing process can protect it. It provides the maximum conditions for your wound to heal while protecting it from a further attack of pathogenic microorganisms and trauma. It’s also crucial for the bandage to be atraumatic (i.e. it minimizes tissue damage) so when removing the bandage, further damage to the wound is avoided.

There are several types of wound dressings utilized in treating moist wounds:

Hydrocolloids. These include the distribution of absorbent particles within the self-adhesive elastomer. You can use this dressing on any light to moderate draining wounds, burns, necrotic wounds, pressure and venous ulcers, and under compression wraps. Leave this type of bandage on your wound for 24 to 48 hours for it to heal – longer for more serious wounds.

Hydrogels. These are sheets of pre-hydrated hydrophilic polymer. This is ideal for necrotic wounds, painful wounds, donor sites, pressure ulcers, second-degree or higher burn levels, infected wounds, and if your wound has little to no excess fluid. Hydrogels can be left on for 24 to 48 hours for the wound to heal – longer for more serious wounds.

Foams. These are normally formed from coated polyurethane. This is designed for moderate to high levels of wound draining, packing wounds, pressure, and venous ulcers either in stage 3 or 4. Foams can be left on for longer but should be replaced if they have absorbed too much blood or other liquid.

Hydrofibers. These are carboxymethylated cellulose and calcium alginates. Use this type if you have stalled or chronic wounds, bedsores, ulcers, surgical wounds, transplant sites, second-degree or higher burn levels, bedsores, and if your wound has a large surface area. Hydrofibers can be left on for a longer period of time without needing to replace them. However, it is still wise to not leave them on for too long, like longer than 3 to 5 days.

Each of these come with properties unique to them, making them suitable for various kinds of wound conditions. However, what may work for a family member or friend may not work the same for you. It’s best to see a doctor for a serious wound to get a correct recommendation for your specific wound.

When Should I Use a Bandage on My Wound?

Getting a minor injury is unavoidable, whether it’s a cut finger or scuffed knee. These injuries are usually very irritating, especially if you hurt a part of your body that you often use. When this happens, make sure to clean your wound with cool water before doing anything else. Remove any debris or dirt out of it using a sterilized tweezer.

Keep in mind that sterilizing your wound with hydrogen peroxide or rubbing alcohol may irritate your wound and can also slow down its healing process.

In terms of bandaging your wound, there’s no exact answer as it concerns small injuries. What type of wound dressings and products you need will depend on the nature of your injury. But if you have a serious wound, it is best to consult with a healthcare professional to treat and take care of it.

If your wound is in a part where it gets dirty usually such as your hands or gets irritated by your clothing like your knee, make sure to bandage it up. However, make sure that the bandage does not come with antibiotics or antiseptics. Keeping wounds moisturized properly on these body parts is beneficial as it will slow down scab formation. 

How to Know When to Change My Bandage?

If you are wondering ‘how long to leave a bandage on a wound?’ then you should also be asking ‘when do I need to change my bandage.’ This is because you may need to change your bandage with a fresh one at some point to ensure your wound is still protected.

Unlike pharmaceuticals with particular instructions on dosage, wound bandages have no specific rules for their changing. You won’t get a consistent answer when it comes to a certain number of days or hours that you should pass that you should leave it on or before you can change it, making general recommendations quite difficult.

The accurate evaluation of your wound and dressing will play a big role in your decision to change the bandage. The areas you need to evaluate are the following:

  • How absorbent the bandage is.
  • The attachment and structural integrity of your bandage to your wound.
  • Contamination of your dressing.
  • Any clinical signs of infections in the affected area.

The bandage may also come off for the following reasons:

  • The edges of your dressing may have adhered to your bedsheets. And as you change position, it may get pulled off. 
  • It may develop channels or wrinkles when placed over a high flexion or friction body part, which may result in an entry point for dirt or bacteria, increasing the risk of infection
  • The bandage surface may be punctured or torn when it comes in contact with your clothing, shoes, and other items around you. 

Remember that at any point the adhesive bandage becomes unattached, you should change it immediately. 

When Do Bandages Reach Max Absorptive Capacity?

You’re most likely to change the dressing once it has nearly reached or exceeded its wound seepage capacity. Different types of bandages have various fluid absorption capacities. A foam dressing typically has a higher level of wound fluid absorption than a hydrocolloid dressing. Nevertheless, the absorption ability of a bandage will still depend on the amount of fluid your wound secretes.

Knowing when your bandage reaches its max absorptive capacity will tell you how long you can leave it on for, or when you need to replace it.

Here’s how you can tell if your bandage has reached its absorbent capacity and therefore you should change it:

  • There are bandage brands and types that may be translucent or transparent. The saturated areas are dark in color or opaque. You can change it once this area is about 75% steeped with wound fluid.
  • If the top coating of your dressing is not waterproof, change it once the wound fluid comes through its top.
  • You can also find a dressing with an indicator line throughout its perimeter. It becomes opaque as it absorbs wound fluid. And as the opacity touches the line, you need to change your bandage dressing.
  • It’s time to change your bandage when its attachment or structure to your wound becomes compromised no matter what its level of saturation is. Your wound may get contaminated with foreign materials or bacteria if the dressing is unattached.
  • Change your dressing if it becomes contaminated with dirt, urine, feces, or any other foreign material even if it’s not unattached.

How to Bandage a Wound

To ensure your bandage stays on for the necessary time for the wound to heal, you have to ensure your bandage the wound correctly.

Although any deep wound with profuse bleeding requires urgent emergency medical attention, you can bandage and manage most minor wounds and cuts at home. Bandaging a wound is a reasonably simple procedure once you’ve cleaned and stopped its bleeding.

  1. Know if the wound requires immediate medical care. You can use a simple Band-Aid on most minor cuts and wounds, and most moderate ones with dressing and medical tape. But some are way too serious for home remedies. Any skin wound involving broken bones and those major injuries to blood vessels with gushing blood that won’t stop needs immediate medical treatment. Also, seek medical attention if a wound to a leg or arm is causing loss of sensation or numbness below the area of the injury as it may mean nerve damage.
  2. Control wound bleeding. Get the bleeding under control before cleaning and bandaging any wound. Use a dry and clean bandage, and then apply very mild pressure over the injury to control its bleeding.
  3. Remove all visible dirt and debris. Use a clean tweezer rinsed in rubbing alcohol to take out any large pieces of glass, dirt, and any objects lodged in the wound.
  4. Cut or remove clothes away from the injury. You’ll be able to access the wound better by doing so. Once bleeding is contained, remove any jewelry and clothing surrounding the wound.
  5. Thoroughly rinse your wound. In most cases, you can use a saline solution for a few minutes to wash out your wound until it’s free of any debris and dirt.
  6. Get the appropriate bandage for the wound. Choose an appropriately-sized, sanitized bandage for the injury. A self-adhesive bandage is ideal for smaller cuts, while larger wounds require a larger dressing.
  7. Secure and cover the bandage. Attach the bandage to your skin on all sides by using a water-resistant, non-stretching medical tape. Ensure to attach the tape to the uninjured and healthy skin area. Do not use electrical tape, duct tape or any industrial type tape. Cover the wound with a clean stretchy bandage or elastic wrap to protect it further. Also, make sure the bandage is not too tight to avoid cutting off circulation to your wound or any injured part of your body.
  8. Change the dressing. Replace the wound dressing when necessary or if it’s reached its opacity level. Replacing an old bandage with a fresh one will keep your wound clean and helps in the healing process.
