Abstract
Cyclic parenteral nutrition is the technique of infusing the intravenous solution in less than 24 hours, during a portion of the day or night, allowing the patient freedom from the intravenous tubing and pump apparatus. In addition, adverse effects oflong-term parenteral therapy, such as liver complications, were reported to be decreased with the use of cyclic parenteral nutrition in adult patients. Literature on the method and effects of cycling in young infants is minimal. This report describes cyclic parenteral nutrition use with guidelines for cycling and the potential beneficial metabolic effects in 10 infants less than 6 months of age who required long-term parenteral nutrition support. Diagnosis, gestational age, length of time on parenteral nutrition, macronutrient intake, growth, and biochemical parameters for the patients are presented. Overall, cyclic parenteral nutrition was well tolerated without clinical symptoms of hypoglycemia, elevated capillary blood glucose concentrations, or abnormal urine glucose levels. The direct bilirubin concentrations showed a decrease or stabilization after cycling was initiated in eight of 10 patients.
