Sternal exploration or closure

When you have open heart surgery , the surgeon makes a cut (incision) that runs down the middle of your chest bone (sternum). The incision hopefully heals itself. But sometimes, people have complications that require treatment.

Two wound complications that can happen within 30 days of open heart surgery are:

• Infection in the wound or chest bone. The symptoms can be pus at the incision, a fever, or feeling tired and sick.
• The sternum separates into two. The sternum and chest become unstable. You might hear a clicking sound in the sternum when breathing, coughing, or moving around.

Description

The health care provider will do exploration and close the sternal wound. They usually take care of this in the operating room. They will:

• Remove the wires holding the sternum together
• Do tests of the skin and tissue in the wound to look for signs of infection
• Remove dead or infected tissue in the wound (debride the wound)
• Rinse the wound with salt water (saline)

After the wound is cleaned out, your surgeon may not close the wound. Your surgeon may pack the wound with a dressing. The dressing will be changed often.

Or your surgeon may use a VAC (vacuum-assisted closure) dressing. It is a negative pressure dressing. It increases blood flow around the sternum and improves healing.

The parts of VAC dressing are:

• Vacuum pump
• Foam piece cut to fit the wound
• Vacuum tube
• Clear dressing that is taped on top

The foam piece is changed every 2 to 3 days.

Your surgeon may put a chest harness on you. This will make the chest bones more stable.

It may take days, weeks, or even months for the wound to be clean, clear of infection, and finally heal.

Once this occurs, the surgeon may use a muscle flap to cover and close the wound. The flap can be taken from your buttocks, shoulder, or upper chest.

Why the Procedure Is Performed

You may have already been receiving wound care or treatment and antibiotics.

There are two main reasons for doing exploration and closure procedures for the chest wound after heart surgery:

• Get rid of the infection
• Stabilize the sternum and chest

Before the Procedure

If your provider thinks you may have an infection in your chest incision, they may:

• Take samples from the drainage, skin, and tissue
• Take a sample of the breastbone for a biopsy

  Biopsy

  A biopsy is the removal of a small piece of tissue for laboratory examination.

• Do blood tests
• Assess how well you are eating and getting nutrients
• Give you antibiotics

After the Procedure

You will likely spend at least a few days in the hospital. After that, you will either go:

• Home and follow up with your surgeon. Nurses may come to your home to help with care.
• To a nursing facility.

At either place, you may receive antibiotics for several weeks in your veins (IV) or by mouth.

Outlook (Prognosis)

These complications can cause problems such as:

• A weakened chest wall
• Chronic pain
• Decreased lung function
• Increased risk of death
• More infections
• Need to repeat or revise the procedure
