because tpn solutions are concentrated and can cause thrombosis of peripheral veins, a central venous catheter is usually required. standard solutions contain up to about 25% dextrose, but the amount and concentration depend on other factors, such as metabolic needs and the proportion of caloric needs that are supplied by lipids. if tpn is given outside the hospital, patients must be taught to recognize symptoms of infection, and qualified home nursing must be arranged. plasma glucose should be monitored every 6 hours until patients and glucose levels become stable.
most patients’ needs for iv fluid and drugs can be met with a percutaneous peripheral venous catheter. short-term hypoglycemia may be reversed with 50% dextrose iv; more prolonged hypoglycemia may require infusion of 5 or 10% dextrose for 24 hours before resuming tpn via the central venous catheter. abnormalities of serum electrolytes and minerals should be corrected by modifying subsequent infusions or, if correction is urgently required, by beginning appropriate peripheral vein infusions. stimulating contraction by providing about 20 to 30% of calories as fat and stopping glucose infusion several hours a day is helpful. choose a solution based on patient age and organ function status; different solutions are required for neonates and for patients who have compromised heart, kidney, or lung function.
and here to help with this is jordan kelley, pharmd. total parenteral nutrition (pn), the dreaded words for most residents and busy pharmacists when a patient is not maintaining an appropriate amount of nutrition. it is known that the best way to improve gut function is to use the gut when it is possible. if a patient is only going to be without enteral nutrition for a couple of days, then they do not need pn. peripheral lines are limited by the osmolality and volume that you can safely give to the patient in a 24 hour period and you will never get them enough nutrition to matter. now you need to calculate the pn – which takes math, science, and a smidge bit of magic (read: clinical judgment).
however, the magic comes in when a patient is obese or malnourished. while this is more of an issue in enteral nutrition, it is important to recognize how the type of protein could be a barrier to successful enteral nutrition. if a patient is diabetic, insulin regimens will need to be adjusted to keep the patient’s glucose under control. at some point the patient and pn have to go their separate ways, and you need to discuss how you are going to get the patient some rebound nutrition or their gut’s hypothetical heart will be broken. i hope these pearls and guidance can help you to make the best decisions for your patients. all of this is to say that your information is in safe hands.
