PHRM 221 Lecture Notes - Lecture 23: Esophageal Varices, Enteral Administration, Feeding Tube
Document Summary
Enteral nutrition : using a tube to access the gi tract (to provide nutrition, water, medication) Not able to take in enough nutrition. Nutritional deficits limiting healing and recovery, treatment options. E. g. bowel in discontinuity (disconnected) , ischemia (hemodynamically unstable) E. g. esophageal varices, strictures (obstruction in the bowel) Nutrition & hydration needs can be met. Trillions of bacteria inhabit the git and depend on our food for their metabolic needs. Tube feeding may reduce risk of bacterial translocation from bowel to blood. Nasogastric normal stomach emptying, able to sit up for feeding. Nasoduodenal gastric stasis, high risk of aspiration, reflux, nausea. Distal tube tip position may influence medication absorption . Ambulatory pancreatitis patient (more comfortable) comfortable for patients and less risk of damage to the gi mucosa. Critically-ill intubated patient , aphasic patient post stroke (check gastric residual) Uncomfortable and pose a higher risk of damage to the gi mucosa.
