Enteral nutrition (tube feeding): nutrition delivered into the GI tract distal to the oral cavity via a tube, catheter, stoma o Used in pts who have a functioning GI tract but are unable to take any or enough oral nourishment o Indications include anorexia, orofacial fractures, head and neck cancer, neurologic or psychiatric conditions which prevent oral intake, extensive burns, critical illness, chemo or radiation therapy Orogastric, nasogastric, nasointestinal tubes: placement into small intestine decreases chance of regurgitating gastric contents into esophagus and subsequent aspiration Gastrostomy and jejunostomy tubes: GT tube may be used when a pt requires EN for an extended time-pt must have an intact unobstructed GI tract and the esophageal lumen must be wide enough to pass the endoscope for percutaneous endoscopic gastrostomy (PEG) tube placement o Jtube: for pts with chronic reflux; this reduces risk of aspiration o Combination GJ tubes allow for simultaneous gastric decompression and small bowel feeding It is important to know which port is the gastric and which is the jejunal o Elevate HOB 30-45 to prevent risk of aspiration o Obtain xray to confirm position of newly inserted nasal/orogastric tube-don’t rely on auscultation method o Flush feeding tubes with 30 ml of warm tap water Q4HRS during continuous feedings or before and after each intermittent feeding-always flush tubes between each med & after all med o Enteral feeding misconnection: inadvertent connection between an enteral feeding system and a nonenteral system such as an IV line, a peritoneal dialysis cath, or a trach tube cuff-severe pts injury/death can occur Parenteral nutrition: admin of nutrients directly into bloodstream o Used when GI tract cannot be used for ingestion, digestion, and absorption of essential nutrients Refeeding syndrome: characterized by fluid retention and electrolyte imbalances o Hypophosphatemia is hallmark of refeeding syndrome and is associated with serious outcomes, including cardiac dysrhythmias, respiratory arrest, and neurologic disturbances o
