What You'll Learn

Clean the wound with soap and water
Cleaning a wound is essential to preventing infection. For a minor cut at the side of your fingernail, you should rinse the wound under clear, running water. You can then gently wash around the wound with soap, taking care to keep the soap out of the cut itself. Avoid using antibacterial soap or soaps with heavy perfumes, as these may irritate the wound.
If there is any dirt or debris in the wound, you can use tweezers to gently remove it. Ensure the tweezers are clean by wiping them with alcohol first. If there is still dirt or debris that you cannot remove, you may need to seek medical attention.
You should also avoid using any cleaning solutions such as hydrogen peroxide or iodine on the wound, as these can irritate the skin and cause further issues.
Once you have cleaned the wound, gently pat it dry with a clean cloth. You can then apply a thin layer of antibiotic ointment to the cut to prevent infection and help the healing process. Finally, you can wrap the cut in an adhesive bandage to protect it. Ensure the bandage is not too tight or too loose, and change it daily or whenever it becomes dirty or wet.
Keeping the wound clean and dressed is essential to prevent infection and promote healing. Inspect your wound carefully for any signs of infection each time you change the bandage, and seek medical attention if you notice any problems.

Stop the bleeding
If you have a cut at the side of your nail, it's important to stop the bleeding to prevent further issues and promote healing. Here are some detailed steps to help you stop the bleeding:
- Clean the wound: Wash any minor cuts gently with soap and warm water to remove dirt and debris. This helps prevent infection and ensures that the wound is clean before dressing.
- Apply direct pressure: Use a clean cloth, tissue, or even the hem of your shirt to apply gentle but firm pressure directly to the wound. Hold it in place for a few minutes to help slow and eventually stop the bleeding.
- Use a clotting agent: Consider using a clotting powder, such as Kwik-Stop Styptic Powder, which can help speed up the clotting process and provide some numbing relief.
- Elevate the injured finger: Keep the injured finger elevated above the level of your heart. This will help reduce blood flow to the wound and promote clotting.
- Cold compress: Apply a cold compress or ice pack to the injured area. Cold temperatures help constrict blood vessels, reducing blood flow to the wound and promoting clotting.
Remember, if the bleeding is severe or does not stop within 10 to 15 minutes, or if there is a large amount of blood collecting under the nail, seek medical attention immediately. Do not try to treat serious bleeding at home.

Apply antibiotic ointment
Once you have cleaned the wound, it is a good idea to apply a thin layer of antibiotic ointment. Antibiotic ointment can help prevent infection and is particularly useful if you think your wound will come into contact with dirt and grime. Ointments such as Neosporin or Polysporin can be applied to a cotton swab or clean gauze and then gently applied to the wound.
It is important not to squeeze ointment directly from the tube onto the cut, as you do not want to contaminate the container. Adhesive bandages are not necessary for minor cuts, but they can be useful to protect the wound from contamination. If you do use a bandage, be careful not to apply it too tightly or too loosely.
If your cut is severe, your healthcare provider may prescribe antibiotics to prevent infection. This is especially important if you have injured the nail bed, as this can cause a fracture or tendon injury. If you have a broken bone, your doctor may need to place a wire in your finger to keep the bone in place.
In some cases, a doctor may recommend keeping the wound open to heal on its own. This is known as debridement and involves the cleaning of the wound and removal of dead tissue and contaminants.

Cover with a bandage
Once you have cleaned the wound and applied a thin layer of antibiotic ointment, the next step is to cover the cut with a bandage. This will protect the cut from contamination and prevent dirt and grime from getting into the wound. Adhesive bandages are not necessary for minor cuts, but they are useful if there is a chance that the wound will get dirty or irritated.
When applying an adhesive bandage, it is important to never touch the pad. Peel off one side of the protective covering and carefully attach the sticky part to the finger, being careful not to apply the bandage too tightly or too loosely. You can use a clean cloth, paper towel, or gauze to wrap and press against the wound. If the cut is on your child's finger, you can wrap the finger with gauze and then use a bandage to secure the gauze in place.
If the cut is more serious, such as a deep cut that requires stitches, your healthcare provider may recommend leaving the wound open to heal on its own. In this case, you may not need to use a bandage, as the wound needs to breathe. However, it is important to follow the advice of your healthcare provider and keep the wound clean and dry to prevent infection.
Remember, even small cuts can get infected, so it is important to protect your healing wound and keep it clean and dry. Inspect your wound carefully for any signs of infection each time you change the bandage. If you notice any redness, swelling, or discharge, seek medical attention as soon as possible.

Monitor for signs of infection
It is important to monitor for signs of infection after a cut at the side of your fingernail. Paronychia, a bacterial or fungal infection, is a common nail infection that can occur. It usually results from bacteria entering the skin through cuts in the cuticle and the nail fold (the skin around the nail). Symptoms of paronychia include pain, swelling, and tenderness around the nail, with skin that is red and warm to the touch. There may also be pus that builds up under the skin, which may leak out of the wound. The drainage is usually a white to yellow, cloudy colour.
If left untreated, paronychia can cause damage to the nail and, in rare cases, can lead to a serious infection that spreads deeper into the finger. Therefore, it is important to be vigilant for any signs of infection and seek medical attention if necessary.
In addition to paronychia, other types of finger infections include felon, cellulitis, infectious flexor tenosynovitis, and deep space infection. Felon is a bacterial infection of the finger pad, usually resulting from a puncture wound, and presents as a swollen and painful fingertip. Deep space infections can also result from puncture wounds and involve the invasion of bacteria into the deep tissue and structures of the hand, such as blood vessels, tendons, or muscles. Infectious flexor tenosynovitis is a type of deep space infection that specifically affects the tendons and tendon sheaths involved in flexing and closing the hand.
To prevent finger infections, it is important to practice good hand hygiene, avoid nail biting, and wear protective gloves when necessary. If you notice any signs of infection, seek medical attention promptly to ensure proper treatment and prevent potential complications.
