When Your Child Needs a Tracheostomy: Suctioning 

In a trach tube, mucus can build up and thicken. As a result, mucus can plug up the trach tube, making it hard for your child to breathe. Regular suctioning of mucus keeps the tube clear. You will be instructed on how to suction mucus to keep the tube clear. You will also be instructed about methods for cleaning catheters and how deeply to insert them while suctioning. It's also important to know how to do CPR for your child with a trach. Below are the basic steps for suctioning. Follow any other instructions you are given.

When to suction

Suctioning is often done just before changing and cleaning the trach tube. It should also be done before your child goes to sleep and when they wake up. But you may need to suction more often, depending on your child’s age and the reason for the trach tube. An older child may be able to tell you if they feel that suctioning is needed. Here are signs that you may need to suction:

  • Your child is breathing more quickly or seems very restless.

  • You hear a whistling or rattling sound when your child breathes.

  • There are bubbles of mucus at the trach opening or you hear gurgling or rattling sounds as if mucus is present.

  • Your child is having trouble breathing or eating.

  • Your child's color is paler.

  • Your child's nostrils are flaring (spread out).

Gathering your supplies

As with cleaning, you may find it easier to set up in the same area each time you do suctioning. Choose a clean, well-lighted space near a sink. It's a good idea to have a resuscitation bag close by, in case of an emergency with the trach. Suctioning supplies include:

  • Clean, disposable, powderless gloves

  • Suction machine, tubing, and catheters (you may also use another premarked catheter to help guide insertion depth)

  • Sterile water

  • Sterile saline solution

  • Syringe or eyedropper

  • Sterile or clean cup

Setting up your equipment

First explain to your child what you are about to do. Then set up what you will need:

  • Wash your hands with liquid soap and water. Scrub your hands for at least 20 seconds. Dry well. You may also use alcohol-based hand sanitizer, if you don't have soap and water. Rub the sanitizer for at least 20 seconds over all areas of your hands.

  • Put on gloves.

  • Attach the catheter to the suction machine. Don’t touch the end that will go into the trach tube.

  • Turn on the suction machine to 50mm Hg to 100mm Hg. Ask your provider about what suction pressure is best for your child. Suction pressure may vary depending on your child's age.

  • Pour sterile water into a cup.

  • Test to see if the catheter is working. Dip the tip of the catheter into the sterile water.

Suctioning the trach tube

Below are basic instructions for suctioning. You may have been given additional instructions for your child.

  • Do this step only if your healthcare provider tells you to: Use a syringe or eyedropper to put a small amount (about 1 mL) of sterile saline solution into the trach tube. This helps loosen mucus.

  • Have your child take a few deep breaths. This may cause your child to cough briefly. This is normal and helps to clear the mucus. 

  • Put a catheter gently into the trach tube as far as you’ve been instructed to do. (Insertion depth depends on the size of your child and the length of the trach tube.)

  • Apply suction by covering and uncovering the suction valve on the catheter.

  • While twirling the catheter, withdraw it to remove mucus. Don't keep the catheter in place for more than 3 to 4 seconds at a time.

  • Draw saline from the cup into the catheter to clear it of mucus.

  • Let your child rest and breathe for 1 to 2 minutes.

  • Then repeat suctioning until the trach tube is clear and makes no more rattling sounds.

  • Check the secretions. Tell the healthcare provider if there are any changes in odor, thickness, color, or amount.

  • Do other steps as instructed. For example, you may also suction your child’s nose and mouth. Or you may need to give extra oxygen (do this only if instructed).

Cleaning up

When you have finished suctioning:

  • Turn off the machine.

  • Throw away the saline and gloves.

  • Follow equipment supplier directions for how to clean the suctioning machine and how often.

  • Wash your hands again even when using gloves.

Making suctioning easier for your child

Suctioning can produce a gagging feeling, which can be scary to your child. Tell your child that this is normal. It may also help to do relaxing activities beforehand. Let your child rest in between suctioning. And don’t suction for any longer than your child can hold their breath. The whole session should last no more than 5 to 10 minutes.

When to call the healthcare provider

Call the healthcare provider right away if your child has any of the following: 

  • Red, painful, or bleeding hole (stoma)

  • Yellow or green, smelly, bloody, or thick mucus from the stoma

  • Fever of 100.4°F (38°C) or higher, or as advised by the provider

  • Swelling around the trach tube

  • Pain when you suction the trach tube

  • Shortness of breath or any trouble breathing

  • Very grouchy

  • Vomiting

  • Trach tube or suction catheter that is hard to insert
