Gastrostomy Feeding Tube Care: Flushing
With gastrostomy tube feeding, you need to keep the tube from getting clogged. You do this by flushing it with warm water after each feeding and before and after giving any medicines.
There are different types of gastrostomy feeding tubes. One type has a connection that lets you plug or push the syringe into the feeding tube port. A newer type has a twist-on safety connector. The twist-on safety connector means you must use a specific type of syringe that twists onto your feeding tube port. Check with your care team to make sure you are following the steps for your specific type of gastrostomy tube. Ask for written gastrostomy tube instructions. Review the material with a care team member before you leave the hospital. Don't hesitate to ask questions and take notes. Have the information repeated as many times as needed until it's clear to you.
Wash your hands with soap and water before and after handling the feeding tube.
