Monitoring Parenteral Nutrition

Guidelines for Monitoring Parenteral Nutrition

Once the need for parenteral nutrition (PN) has been established and nutritional requirements are determined, PN should be introduced progressively and monitored closely. The risk of PN-associated complications such as “refeeding syndrome“, hypertriglyceridemia, hyperglycemia, catheter infections, and bone demineralization can be minimized by carefully and systematically monitoring the clinical and laboratory parameters.1,2

The Importance of Biochemical Monitoring

During the early phase of PN, biochemical monitoring (blood glucose, urea, electrolytes, and blood gases) should be performed daily. The full set of laboratory parameters should then be repeated two to three times a week.3

In patients receiving total PN the possibility of supplemental feeding via enteral/oral means should be considered within regular re-evaluation.  Regular monitoring of PN can result in reduced complications and lower costs.1

The guidelines for monitoring of PN include1:

Nutritional and Clinical Monitoring

The following parameters should be monitored and documented on a regular basis1,4:

The following guidelines are for monitoring of metabolic parameters (exemplary schedule)4:
