What is intravenous feeding?
intravenous feed, also called parenteral nutrition, adds food to the veins. This gives nutrition directly to the bloodstream and avoids digestion processes. Patients may require intravenous feed if their digestive system is unable to pass or absorb food. This can be the result of trauma, surgery, damage to gastrointestinal (GI) tract, disorders that draw non -functional intestines, coma or short intestine syndrome.
The gastrointestinal tract is a system of organs that use, spend and exclude food. It begins with a mouth that takes food and starts to break it with chemicals in saliva and chewing. The food now called the bolus, then passes through the pharynx in the esophagus, which extends from the neck to the stomach. The stomach still decomposes the bolus and turns into Chyme. Chym then takes the intestines or intestines that are responsible for the absorption of the nutrients and the preparation of waste materials for excretion.
If this system does not work properly, the patient must receive food through enteral feeding or parenteral nutrition (PN). During the enteral feeding, the tube is inserted into the gastrointestinal tract of the patient, usually over the nose, stomach or small intestine. The tubes of feeding the nose and stomach bypass the mouth and neck, but still use the stomach. The samonomia, in which the feed tube is surgically placed in the small intestine, bypasses the mouth, neck and stomach, but still uses the intestines. Because this is less risk, enteral feeding is often preferred over parenteral feeding.
Some patients are not eligible for enteral feeding and require overall parenteral nutrition (TPN), which only relies on intravenous feeding. This procedure is most commonly performed in patients whose GI tract is needed due to surgical procedure. Intravenous feeding may also be needed if the patient has chronic vomiting or diarrhea, or if a severely malnourished patient requiresSurgery. Lack of development in the GI tract of the child, congenital defects in the digestive system, intestinal obstruction and intestinal inflammation, such as Crohn's disease, may also require TPN.
patients who need intravenous feeding usually get a local anesthetic before the doctor puts a feed tube or catheter into the vein. Doctors usually use a subclavian vein, located under the collarbone, a jugular vein located in the throat or a large vein in the arm. The tube adds a small amount of liquid nutrition continuously to make the vein open. A larger amount of nutrition is infrased about every few hours, depending on the patient's feeding plan. A device called an infusion pump is used to control timing and the amount of nutrition administered.
When the patient regains Strength, he can often return to normal eating. However, some patients require long -term intravenous feeding. These chronic patients with PN can be able to administer their nutrition at home independently. Between side effects, although unusual, include blood clots, cholecystitis or bladder inflammation, bacterial and fungal infections and liver failure due to excessive glucose in nutritional solution.
