cellulitis procedure preparation

Overview

Cellulitis is a bacterial skin infection that spreads into the deeper layers of the skin and the tissues underneath. It usually starts when bacteria enter through a cut, scrape, or other break in the skin. In some cases, a small procedure may be needed to drain pus or remove damaged tissue.

Cellulitis is fairly common. It affects people of all ages, though certain conditions can make it more likely.

It can affect anyone, but you may be more at risk if you have diabetes, circulation problems, or a weakened immune system. It also appears more often in older adults and people with skin injuries or long-term swelling in the arms or legs.

Symptoms

Common symptoms

• Red, swollen, warm, and tender skin, often on the lower legs
• Fever or chills
• Pain or tenderness in the affected area
• Blisters or dimpling of the skin
• Rapid spreading of redness

Symptoms in children

• The same signs as adults, but younger children may be fussy, tired, or have a fever
• The infection often appears on the face or around a wound

Symptoms in older adults

• The redness may be less obvious, but confusion, sleepiness, or a sudden change in function can be signs
• Older adults may not run a high fever even with a serious infection

Causes

Main causes

• Bacteria, usually Streptococcus or Staphylococcus, entering through a break in the skin
• Cracks in the skin, athlete's foot, insect bites, or surgical wounds
• Inflammatory skin conditions like eczema that cause small breaks in the skin

Risk factors

• A weakened immune system from illness or medication
• Diabetes, especially if blood sugar is not well controlled
• Chronic swelling in the legs or arms (lymphoedema)
• Obesity
• A history of cellulitis
• Tight or partially healed wounds

When to see a doctor

See a doctor urgently if:

• If you see spreading redness, especially rapidly
• If you have a fever and feel unwell
• If you have a painful, swollen area that grows quickly

Book a routine appointment if:

• If you have a skin wound that becomes red, warm, or painful after a few days
• If you keep getting cellulitis or skin infections

Diagnosis

A doctor will usually diagnose cellulitis by examining the skin and asking about your symptoms. They may look for signs of injury, swelling, and warmth.

Tests that may be done

• A blood test to see if the infection has spread
• A culture (swab) from the affected area if there is an open wound or pus
• Sometimes an ultrasound or imaging test if there is an abscess that needs draining

What to expect at your appointment

The doctor will ask about your medical history and any recent injuries. They will examine the area and may press on it gently. If a procedure is needed, they will explain the steps and what you can do to prepare.

Treatment

Cellulitis is usually treated with antibiotics. If there is an area of pus or deep infection, a procedure may be needed to drain it. This article focuses on preparing for that procedure.

Self-care at home

• Keep the affected limb raised to reduce swelling
• Apply a cool, clean cloth to the area for comfort
• Take pain relief as recommended by your doctor or pharmacist
• Drink plenty of fluids and rest
• Keep the skin clean and dry, but do not soak in water

Medical treatments

Antibiotics are the mainstay of treatment for cellulitis. They are usually given by mouth, but in more severe cases may be given through a vein (intravenously) in the hospital. If an abscess is present, it may need to be drained using a needle or a small incision. Sometimes surgery is needed to remove dead tissue. Always follow your doctor's instructions about the procedure, including any fasting (not eating or drinking) if you are having surgery.

When is surgery considered?

Surgery is not always needed. It is used when the infection is very deep, when an abscess cannot be drained with a needle, or when there is a lot of dead tissue that must be removed. Your care team will explain this clearly if it applies to you.

Living with this condition

During recovery, you may need to take time off work or limit activities. Keep the area clean and protected, and follow your healthcare team’s advice about changing bandages and looking after the wound. It is normal to feel tired as you heal.

Lifestyle tips

• Eat a balanced diet to support your immune system
• Keep your skin moisturized to prevent cracks
• Protect any cuts, scrapes, or insect bites with a clean bandage
• If you have diabetes, manage your blood sugar carefully

Diet and exercise

There is no special diet for cellulitis, but eating well helps your body fight infection. Gentle movement, like walking, is fine once your care team says it is okay. Avoid strenuous activity if the affected limb is swollen or painful.

Mental health and emotional wellbeing

A skin infection can be distressing, especially if you need a procedure or are in hospital. It is normal to feel anxious or down. Talk to your healthcare team if your mood is low. Remember that the infection is treatable and you are being looked after.

Prevention

You can reduce the chances of another cellulitis by caring for your skin and treating breaks in the skin quickly. If you have athlete's foot or eczema, treat those conditions. If you have repeated episodes, your doctor may discuss long-term prevention.

Vaccines

No vaccine prevents cellulitis directly, but keeping up to date with tetanus shots and other routine vaccines is important, because skin breaks can carry bacteria.

Screening programmes

If you have conditions that raise your risk, such as diabetes or poor circulation, regular check-ups can help catch problems early.

Complications

If left untreated

• Sepsis, a life-threatening body-wide infection
• An abscess that grows deeper and becomes more painful
• Damage to the skin and tissues that may need surgery
• Recurring cellulitis in the same area

Long-term outlook

With prompt treatment and, if needed, a simple procedure, most people recover fully. The infection usually improves within days of starting antibiotics, though it can take a few weeks for the skin to look normal again. You can take steps to prevent it coming back.
