The patient or caregiver must be adequately versed in the management of the gastrostomy and jejunostomy tubes as well as in the potential complications of enteral feeding using such tubes buy ampicillin 500mg low price. Intermittent replacement of these tubes is generally on an as- needed basis although some nutrition programs provide replacement on a predefined timetable generic ampicillin 250mg online, for example every 12 to 18 months. Home parenteral nutrition patients and/or their caregivers need to undergo appropriate training in aseptic techniques as well as training in management of catheter and pump care. This training may be done in a hospital setting or in an outpatient setting depending on the underlying condition of the patient. Regular bloodwork and follow-up visits with the physician, home care nurse and dietitian are essential. Long-term complications of home parenteral nutrition include the usual complications of parenteral nutrition. However, line sepsis, venous thrombosis and liver disease represent profound challenges in the long-term setting. Metabolic bone disease is also common in patients receiving home parenteral nutrition, but is likely due to the underlying conditions which require home parenteral nutrition (e. Malnourished patients have energy requirements which are 10% to 20% below predicted by the Harris-Benedict equation, as discussed above. Furthermore, such patients are at particular risk for refeeding syndrome, consisting of a variety of problems occurring when nutrition is initiated. As the intracellular compartment is regenerated with refeeding, there may be shifts of extracellular substances into the cell including phosphorous, potassium and magnesium. These shifts are facilitated by insulin which is released in response to glucose given as part of the nutrition. It is very important to provide adequate amounts of phosphorous, potassium and magnesium. Vitamins, especially thiamine, should be administered at the onset of nutritional repletion and continued for several days. Parenteral nutrition plays a role as adjunct therapy in Crohns patients who are obstructed or have short bowel syndrome. There is clearly a role for enteral nutrition in the pediatric population, where this modality provides for linear growth in growth- retarded patients. It should be noted that monomeric (elemental) diets have not been shown to be more effective than polymeric diets when these formulas have been compared. First, infusion of nutrients into the duodenum stimulates pancreatic secretion, which may be theoretically harmful in patients with pancreatitis. Second, patients with pancreatitis frequently have vomiting and ileus as a manifestation of their condition. Finally, the pancreas secretes both exocrine and endocrine products important in nutrition, namely pancreatic enzymes and insulin. Despite these considerations, the preferred method of providing nutrition in acute pancreatitis is elemental jejunal feeding which has been found to be safer than parenteral nutrition with fewer septic complications. Uncommonly, parenteral nutrition may be necessary if enteral feeding is not tolerated. Canadian Consensus Conference on the management of gastroesophageal reflux disease in adults update 2004.
