It was quite amazing to have actually been able to feed someone through a nasogastric tube (NGT). To those who don't know what a nasogastric tube is, it is a tube that is inserted in the nose that passes at the back of the mouth, through the esophagus and opens directly into the stomach.
Tube feedings are given when a person is unable to eat or tolerate enough food and/or oral supplements to meet his/her nutritional needs.
It's quite easy to feed a patient via NGT. Just make sure that the tube is patent and is correctly positioned in the stomach by injecting air and auscultating (listening with the use of a stethoscope) the right upper quadrant of the abdomen for a whooshing or gushing sound. If there is the sound then pour the nutrient mixture or "bolus" into the asepto syringe and allow the bolus to flow through the tube. Just remember to kink the tube when opening or adding a bolus to the syringe to prevent air from entering the tube and causing stomach distention. And to finish the feeding, flush the tube with 30cc or 30 ml of water.
There's nothing hard with NGT feeding. It's just that your arms would really ache especially if the bolus would flow very slowly because it's too viscous or the patient requires frequent feedings.
