Percutaneous Catheter Drainage (PCD)

What is a percutaneous drain?

The word percutaneous means 'through the skin'. A percutaneous drain is a small plastic tube placed in any part of your body, which needs to be drained off a collection of fluid.

A percutaneous drainage procedure is a way to remove excess fluid from your body such as the abdomen, or chest using a small tube (called a drain) that is inserted through a tiny incision in the skin. This procedure is often used to treat fluid buildup due to an underlying liver disease, or to drain infected fluid collections. Sometimes, the fluid is sent for testing to help doctors understand its cause.

Why is this Procedure Needed?

PCD may be needed if there is:

• a collection of fluid, which might be causing discomfort or difficulty breathing.
• pus: draining it can help treat the infection.

PCD helps alleviate symptoms like pain, fever, or swelling by removing the fluid and allowing the area to heal.

Who Will Perform the Procedure?

A radiologist, a specialist doctor trained in using imaging tools like ultrasound or CT scanners, will perform the procedure. They will use the images from these machines to guide the insertion of the drain into the right spot.

Preparing for the Procedure

The procedure is usually done in the radiology department, either in the CT or ultrasound area. You might need some blood tests beforehand to check for any risks, especially if you're taking blood thinners. Be sure to inform your doctor if you have any allergies or previous reactions to contrast dyes used in imaging.

What Happens During the Procedure?

PCD is performed under local anesthesia or sedation to ensure you are comfortable. Here's a basic overview of the process:

• 1. Imaging guidance (ultrasound or CT scan) will be used to identify the location of the fluid collection.
• 2. The doctor will clean the skin and apply local anesthesia to numb the area.
• 3. A needle will be inserted through the skin to access the fluid. You may feel some pressure, while the needle and drain are inserted, but the procedure itself is generally not painful.
• 4. Once the drain is in place, it will stay there to collect the fluid, and a collection bag will be attached to it. The drain may remain in place for a few hours or longer, depending on how much fluid is being drained and its type.

How Long Will the Procedure Take?

The procedure usually takes about 30 minutes, but you may spend more time in the department for preparation and recovery.

After the Procedure

• You may need to stay in bed for a few hours for monitoring.
• A nurse will check your pulse and blood pressure, and if you experience pain, pain-relief medication will be provided.
• Depending on the situation, you might stay in the hospital overnight or be discharged the same day. Make sure to rest and avoid strenuous activities for the rest of the day.
• You won't be able to drive for 24 hours, so arrange for a friend or family member to take you home.

Possible Risks and Complications

While percutaneous drainage is generally very safe, like any procedure, it has some risks. The radiologist will explain these risks and ask you to sign a consent form before going ahead.

Discharge Instructions for Percutaneous Drainage

To ensure proper healing and prevent infection, follow these care instructions:

• 1. Keep the catheter site clean:
  • Wash your hands before touching the catheter or dressing.
  • Keep the area dry and clean. If the dressing becomes wet or soiled, change it immediately.
• 2. Flush the catheter (if instructed by your doctor):
  • You may need to flush the catheter with sterile saline to keep it clear and prevent blockage.
• 3. Monitor the drainage:
  • Keep track of the amount and appearance of the fluid being drained. Record daily output, noting any changes in color or consistency.
• 4. Avoid activities that may pull or kink the catheter:
  • Do not submerge the catheter in water (e.g., swimming or bathing). Make sure to cover the dressing with plastic wrap while taking shower to keep it dry.
  • Be gentle around the catheter site to avoid dislodging it. Avoid any movements that cause pulling sensations or pain around the catheter, or that may cause the catheter to bend/ kink.

Follow-Up Care

• You will need follow-up visits to monitor the drainage and ensure that the catheter is working properly.
• Your doctor will advise you on when the catheter can be removed, typically once the fluid collection has resolved.

When to Call Your Doctor

Contact your doctor immediately if you experience any of the following:

• Increased pain around the catheter site.
• Redness, swelling, or warmth at the catheter insertion site (signs of infection).
• Fever over 101°F (38.3°C) or chills.
• Leakage or drainage of blood from the catheter site.
• Dislodgement or movement of the catheter.
• A decrease in drainage by half within 24 hours
