Before cleaning or unblocking a feeding tube, make sure to wash your hands well with warm, soapy water to rid them of bacteria. A G-tube is normally held in place with a G-tube holder. To unclog a blocked tube, remove it from the holder and prep a 30mL or 60mL piston syringe. Pull back until the blockage is sucked out. To clean the tube, fill a flush syringe with warm water and push the water through the unattached tube. Once the tube has been washed thoroughly with warm water, you may reattach it so the patient can resume feeding. Be sure to place it back in the holder to help prevent blockages in the future.
