Describe the factors to consider when selecting a feeding route for a patient who needs tube feedings

Answer 1

?Transnasal access is usually preferred when the tube-feeding duration is expected to be less than 4 weeks, and enterostomies are often appropriate when tube feedings are planned for longer periods. Gastric feedings (nasogastric and gastrostomy routes) are preferred whenever possible. These feedings are more easily tolerated and less complicated to deliver than intestinal feedings because the stomach controls the rate at which nutrients enter the intestine. Gastric feedings are not possible, however, if patients have gastric obstructions, motility disorders that impair stomach emptying, or inadequate stomach volume due to prior gastric surgery. Gastric feedings are often avoided in patients at high risk of aspiration. Aspiration pneumonia may result. Although clinicians frequently administer nasoduodenal or nasojejunal feedings to reduce the likelihood of aspiration, clinical studies have not found an increased incidence of pneumonia in patients who receive gastric feedings.
