Incision and drainage

life science Maturity 5-7 Next article →

Sometimes, fluid builds up under the skin. This can happen with a boil or an abscess. This buildup creates a lot of pressure. A doctor can help using incision and drainage. This is also called clinical lancing. It is a minor surgical procedure. It helps release pus or pressure from the body.

First, a doctor treats the area with an antiseptic. This is a liquid like an iodine-based solution. Next, they make a small incision. An incision is a tiny cut in the skin. They use a sterile instrument to do this. They might use a sharp needle or a pointed scalpel. This allows the pus to escape. It drains out through the small cut.

Doctors follow specific steps for different types of infections. For large abscesses in the abdomen, they use a tube. This tube helps the fluid drain out. They may also use a peripherally inserted central catheter line. This line helps them prepare for septic shock. For simple skin abscesses, antibiotics might not be needed. This is true if the drainage works well.

Caring for the wound is a very important part. A doctor may cover the area with gauze. They then use a sterile dressing. You should wash the wound with normal saline. This should happen at least twice each day. You must also change the dressing. If there is a risk of certain germs, doctors use antibiotics. They may use a drug called vancomycin. This fights staphylococci and streptococci.

There are different ways for the skin to heal. One way is called secondary intention. This means the wound is allowed to close on its own. Another way involves closing the edges of the cut. This happens when the infection is gone. You might see healthy granulation tissue at the base. Then, a doctor may use butterfly stitches. They might also use staples or sutures to close it.
