Overview of Paronychia Drainage

Acute paronychia is one of the most common hand infections. It usually happens when the barrier between the nail and the skin gets broken, allowing bacteria or fungi to enter and cause an infection. This can be caused by habits like nail-biting, picking at hangnails, getting manicures, trauma to the nail or ingrown nails.

Different types of bacteria or fungi can cause this infection. The most common one is called Staphylococcus aureus, which includes a type that is resistant to some antibiotics (MRSA). Other types of bacteria may also be involved, especially if the person often puts their hands in their mouth or bite their nails. Some types of paronychia can be caused by viruses, like herpes, or by fungi, like Candida albicans.

Paronychia can be either acute or chronic. Acute means it has been present for less than six weeks, whereas chronic means it’s been present for six weeks or more. Chronic paronychia is usually caused by repeatedly exposing the nail to irritating substances.

Sometimes it can be tricky to differentiate between paronychia and a similar condition called herpetic whitlow, which is a herpes simplex virus infection that causes blisters on the finger. Usually, surgical drainage is not needed for herpetic whitlow unless another bacterial infection is also present.

Paronychia can also affect the toes, usually alongside ingrown toenails. The focus here though, is on acute paronychia of the hand.

To diagnose acute paronychia, doctors look for signs of pain, swelling and redness around the nail. If the infection gets worse, pus may start to build up along the nail fold. If left untreated, this pus can spread to underneath the nail plate, causing further trouble. Doctors can use a simple test to check for pus. When they apply gentle pressure to the affected finger, the area around the nail may change color, indicating there is pus underneath.

However, another condition called a felon – which is an infection in the tip of the finger – should not be mistaken for paronychia. Although one can lead to the other, they are distinct conditions. Accurate diagnosis is crucial to identify the need for surgical drainage.

In early paronychia, without pus, antibiotics with regular check-ups are usually suggested. If there’s a chance the infection could be caused by bacteria often found in the mouth, then a broad-spectrum antibiotic (that works on a broad range of bacteria) is preferred.

In serious cases where pus is present, the doctor may need to carry out additional tests such as blood tests, check for diabetes, or take an X-ray to check for any broader issues such as fractures, foreign objects, or bone infection. In all cases where there is pus built up, the infected area will need to be drained, usually under the care of a specialized hand surgeon.

Anatomy and Physiology of Paronychia Drainage

The tip of your finger, which is beyond where the tendons attach, is made up of bones and soft tissues, including specialized tissues that form and support the nail. These specialized tissues include the nail plate, perionychium, and nail bed. The nail plate is the hard part of the fingertip. It helps with detailed motor tasks by providing grip and a surface for the finger pulp to increase the sense of fine touch.

The perionychium is made up of the soft tissues on the sides and base of the nail plate. The paronychium is on the side, the hyponychium is at the base, and the eponychium is at the top of the nail plate. The nail bed, also part of the perionychium, is divided into the germinal and sterile matrices. The germinal matrix is in charge of most of the nail plate’s growth and is located deep in the eponychial fold with its end at the lunula, the crescent-shaped part of the nail plate that we can see. On the other hand, the sterile matrix, which is a darker shade located after the lunula, helps strengthen and ground the nail plate.

If an abscess forms, it might initially show up on one side of the nail plate (paronychium), but this infection can spread to involve the top of the nail plate (eponychium), the other side of the nail plate, or the nail bed beneath the nail plate. If all parts are involved, it’s called a paronychial infection. If it’s ignored, results might include interrupted nail growth, deep infections (felon), bone infections (osteomyelitis), skin infections (cellulitis), and lymphangitis (a condition where lymph vessels are infected).

Why do People Need Paronychia Drainage

If someone has a condition called acute paronychia, which is an infection of the skin around the fingernails or toenails, they may need to have it drained. This is usually the case if there is a clear collection of pus, known as an abscess, or if the infection hasn’t gotten better after taking oral antibiotics.

When a Person Should Avoid Paronychia Drainage

There’s no definitive reason not to treat an acute paronychia, a nail infection, by draining it. However, some factors can affect whether this treatment is suitable. These include:

If a patient is taking anticoagulants, which are medicines that prevent blood clots. This can cause bleeding problems during the procedure.

If the patient has diabetes, it’s important to make sure it’s well-controlled before the procedure. Diabetes can affect the body’s healing process.

There may also be additional factors specific to each patient that have to be taken into account before deciding to go ahead with the procedure. Always make sure to discuss these factors with your doctor to ensure you’re receiving the best possible care.

Equipment used for Paronychia Drainage

Your doctor will wear personal protective equipment (PPE) like masks, goggles, and sterile gloves for safety. They will use an antiseptic solution, which can be either chlorhexidine or povidone-iodine, to clean the area where the procedure will be done. The clean area is then covered with a sterile drape to maintain cleanliness.

A “digital block” will be done. This is a type of numbing process that uses a 10 mL syringe and a small needle (25 to 27-gauge) to inject a local anesthetic – for example, 1% lidocaine with epinephrine – into the area where the procedure will be done. This ensures you won’t feel pain during the procedure. Additionally, a finger tourniquet (a device to control bleeding) might be used, but this is optional.

Your doctor will use a scalpel blade (number 11 or 15) to make a cut. Scissors will also be used, specifically tenotomy scissors if they are available. Small forceps are also used to hold tissue or other objects during the procedure.

A nail elevator device like a Freer elevator or Mitchell trimmer may also be used if available. After the procedure, the area will be cleaned with a normal saline solution with or without an antiseptic solution.

For the dressing, your doctor will cover the procedure area with an interface dressing (like a silicon-based dressing), gauze, and a digital dressing. There are also tools for sampling like a microbiology swab or a 1 mL syringe for fluid sampling which can be used to check for possible infections.

Who is needed to perform Paronychia Drainage?

This procedure only needs one person, such as an emergency doctor, primary care doctor, nurse, or surgeon. But, for patients who find it hard to remain still or calm, like young children, or people with conditions like autism or developmental delay, they might need more people to help. This could either be to distract the patient or to give them anesthesia (which is a medication to induce unconsciousness) so the procedure can be done safely.

Preparing for Paronychia Drainage

Before any medical procedure, it’s important for the doctor to talk with you or a family member who can make decisions for you. This is called getting “informed consent.” The doctor will tell you about what is going to happen, what you need to do after the procedure, and how it can help. They should also talk about any possible problems that could happen. For example, if the doctor needs to remove part of the nail, they should tell you that it should grow back completely in about 3-4 months.

Once you understand and agree to the procedure, the doctor will clean your hand where the surgery will happen. They’ll use a special solution to kill any germs and then cover the area with a clean sheet.

Paronychia, the medical term for a nail infection, can be really sore. So the doctor will inject a local numbing medicine to help with pain during the procedure. They usually use a medicine called 1% lidocaine with epinephrine, which also helps to reduce the amount of bleeding. Sometimes, if the area keeps bleeding, the doctor might use a tourniquet (like a tight band) around the finger to help slow the blood flow. This allows them to see the area more clearly while they work.

How is Paronychia Drainage performed

Abscesses, or pockets of pus in your body, can be tricky to treat depending on where they’re located and how big they are. There’s no hard-and-fast-rule, and doctors usually decide on the best treatment plan depending on each specific case.

If the abscess is only in the skin fold next to the nail (paronychial fold), a surgical device is used between the nail and the skin to gently lift and drain the pus. This can be done using a blunt device or a sharp device like a scalpel, scissor, or needle based on the situation.

If a smaller abscess involves the protective layer over a nail (known as the eponychium), the doctor uses a similar technique to lift it up and allow the pus to come out. A small cut may be made on the most swollen point to help relieve the pus. If there happens to be a larger abscess in this area, the doctor might have to check for pus under the nail to decide if removing the nail is necessary.

If the abscess is under the nail (subungual abscess), the best option is usually to remove the entire nail. To do this, a surgical instrument is used to gently lift the nail off the bed. While removing only part of the nail might sound less intense, it could leave some pus behind and it’s a more technically challenging procedure. Removal of the whole nail ensures all the pus is cleared out and it’s a fairly simple procedure. Some folks worry about how the nail will regrow after it’s been removed, but research has shown that most nails grow back normally within 3 to 4 months after removal.

After removing an abscess, the doctor will typically take a sample of the fluid and swab the area to figure out what type of bacteria caused the infection. The area would then be thoroughly cleaned with a saline and disinfectant solution and then properly bandaged up.

Most patients can go home after this procedure, but hospitalization might be necessary if there are severe complications, like skin infection (cellulitis), infection spreading in the lymph vessels (tracking lymphangitis), or bone infection (osteomyelitis). Usually, patients are given oral antibiotics for a week to 10 days, but some studies have shown that antibiotics might not be needed if the abscess was fully drained. The patient should go back to the doctor several days after the procedure to have the wound cleaned, the dressing changed, and to make sure the prescribed antibiotics are effective against the bacteria that caused the infection.

Possible Complications of Paronychia Drainage

While the risks associated with surgical drainage are quite rare, they could happen, and it’s important for patients to know about them. Just like any medical procedure, it has general risks such as pain, bleeding, infection, and scarring, and there are also some more specific risks. These can include a return or partial removal of the infection – this might happen if all the pus isn’t drained out or if the bugs causing the infection don’t respond to the antibiotics used. Those with a weakened immune system tend to face a higher risk of this happening.

If an abscess, a pocket of pus, keeps coming back, it might lead to some other medical conditions like a bone infection (osteomyelitis), a painful infection on the tip of the finger (felon), skin infection (cellulitis), or a whole-body infection (sepsis). Unclear changes in the growth of the nail don’t happen often. Usually, if they do appear, they’re a result of the original infection. In rarer cases, they might also be caused unintentionally by medical treatment.

What Else Should I Know About Paronychia Drainage?

Paronychia, a common infection that affects both kids and adults, can often be handled in clinics, hospitals, and even in surgery departments. It can be treated usually with medications like antibiotics. However, if there’s a pocket of pus, known as an abscess, it generally requires a minor surgical procedure to drain it.

Paronychia drainage can have several effects on the finger. If an abscess forms, it may initially appear on one side of the nail plate but can spread to other parts of the finger, including the top of the nail plate, the other side of the nail plate, or the nail bed beneath the nail plate. If all parts are involved, it is called a paronychial infection. Ignoring the infection can lead to complications such as interrupted nail growth, deep infections, bone infections, skin infections, and lymphangitis.

You may need paronychia drainage if you have an acute nail infection that is causing pain, swelling, and pus formation. Drainage can help relieve the pressure and pain associated with the infection and promote healing. However, there are certain factors, such as taking anticoagulants or having diabetes, that may affect whether this treatment is suitable for you. It is important to discuss your specific situation with your doctor to determine the best course of action.

You should not get Paronychia Drainage if you are taking anticoagulants, have uncontrolled diabetes, or have other factors that may affect the success of the procedure. It is important to discuss these factors with your doctor to ensure you receive the best possible care.

The recovery time for Paronychia Drainage can vary depending on the individual and the severity of the infection. In general, most patients can go home after the procedure and are typically given oral antibiotics for a week to 10 days. It is important for patients to follow up with their doctor to have the wound cleaned, the dressing changed, and to ensure the prescribed antibiotics are effective against the bacteria that caused the infection.

To prepare for Paronychia Drainage, the patient should inform the doctor about any medications they are taking, especially anticoagulants, and ensure that their diabetes is well-controlled. The doctor will wear personal protective equipment (PPE) and use an antiseptic solution to clean the area. The patient will receive a local anesthetic to numb the area, and the doctor will use surgical instruments to drain the abscess and clean the area before bandaging it up.

The complications of Paronychia Drainage include a return or partial removal of the infection, a weakened immune system increasing the risk of this happening, the development of other medical conditions such as osteomyelitis, felon, cellulitis, or sepsis, and unclear changes in the growth of the nail, which can be a result of the original infection or caused unintentionally by medical treatment.

Symptoms that require Paronychia Drainage include a clear collection of pus, known as an abscess, or if the infection hasn't improved after taking oral antibiotics.
