Feeding tube - infants

Alternative Names

Gavage tube - infants; OG - infants; NG - infants


A feeding tube is a small, soft, plastic tube placed through the nose (NG) or mouth (OG) into the stomach. These tubes are used to provide feedings and medications into the stomach until the baby can take food by mouth.


Feeding from the breast or bottle requires strength and coordination. Sick or premature babies may not be able to suck or swallow well enough to bottle or breastfeed. Tube (gavage) feedings allow the baby to get some or all of their feeding into the stomach. This is the most efficient and safest way to provide good nutrition. Oral medicines can also be given through the tube.


A feeding tube is gently placed through the nose or mouth into the stomach. It is most often taped in place. An x-ray can confirm correct placement. In babies with feeding problems, the tip of the tube may be placed past the stomach into the small intestine. This provides slower, continuous feedings.


Feeding tubes are generally very safe and effective. However, problems may occur, even when the tube is placed properly. These include:

  • Irritation of the nose, mouth, or stomach, causing minor bleeding
  • Nasal stuffiness and possibly a nasal infection if the tube is place through the nose

If the tube is misplaced and not in the proper position, the baby may have problems with:

  • An abnormally slow heart rate (bradycardia)
  • Breathing
  • Spitting up

Rarely, the feeding tube can puncture the stomach.
