The pleura (pleurae when talking about both sides of the body) is a thin, slippery layer of tissue that helps protect the lungs. There are 2 layers of pleurae:
The pleurae cushion the lungs and help them move freely as you breathe. In between the pleura is an area called the pleural space, or pleural cavity. There is a small amount of fluid (called pleural fluid) in this space. There are normally 10-20 milliliters (about 1 tablespoon) of fluid in this space.
Sometimes, too much fluid can build up in the pleural space. This extra fluid is called a pleural effusion. A pleural effusion can be caused by a few things, such as cancer (malignancy), congestive heart failure (CHF), and infection. About 40% of pleural effusions are caused by cancer. Cancers of the lung and breast, lymphoma, and leukemia are the cancers most often linked with pleural effusion. Pleural effusions can happen once, or they may keep happening (recurrent).
The pleural effusion can affect one or both lungs. The extra fluid makes it hard for your lungs to work as they should. Signs and symptoms of pleural effusion are:
If the fluid in your pleural space keeps coming back (recurrent pleural effusion), your healthcare provider may want to place an indwelling pleural catheter, often called a PleurX™. The PleurX™ drains the extra fluid from the pleural cavity. It can help ease the symptoms you are having.
The pleural catheter is a flexible tube that is inserted through an incision (cut) in your chest and placed in the pleural cavity. The catheter sits in the pleural cavity and has many holes in it to collect the extra fluid. The rest of the
catheter sits outside of your body and is coiled up and covered by a bandage when not in use.
The PleurX™ catheter is usually placed as an outpatient procedure, meaning you can go home afterward. The procedure usually takes 45-90 minutes. You will have an IV placed and be given medication to make you sleepy. During the procedure:
If you are going home after the procedure, you will need to have someone drive you home. Your provider will tell you when you can go back to normal activity and when to shower. You will probably have a visiting nurse come to your house at first. Call your provider if:
Your healthcare team and the visiting nurse will teach you how to care for your PleurX™ catheter and incisions. They will also teach you how and when to drain the fluid. Once you are comfortable, you will be able to change your dressing, check that your catheter is working, and drain the fluid on your own or with the help of a caregiver. In general:
Change your dressing at least once a week, or as directed by your provider. Change it earlier if it is wet, soiled, or has come loose.
Most often, you will need to drain the fluid from your PleurX™ every day, or as directed by your provider. If you have pain when you empty the fluid, take prescribed pain medication about 30 minutes before you drain the fluid. Your provider will tell you how much fluid to drain and what it should look like. Keep a log of when you drain, how much fluid you drained, and what the fluid looked like. Never drain more than 1,000 milliliters in one day. Most times, the PleurX™ catheter is capped and a vacuum bottle will be used to empty the fluid.
*If you have a drainage bag instead of a capped catheter, your provider will tell you how and when to empty this bag.
Your care team will tell you how to throw out the fluid that you drain, but most often you can flush it down the toilet. If you have problems with draining the fluid or if the fluid doesn’t come out, call your provider for instructions.
