Abstract: With the improvements in medical technology, more premature infants and infants with congenital intestinal malformations or other conditions who need parenteral nutrition (PN) support can survive. PN technology has become an important therapeutic strategy in neonatal intensive care units. Due to differences in the qualifications of medical staffs, hospital pharmacy management, hospital level, etc, the composition and preparation methods of PN prescription vary greatly in different regions and hospitals in China. In addition, delays in the starting time of PN, unreasonable formula of nutrition components, poor prescription review, large workload involved in the preparation of PN for nurses, and waste of drugs are prone to happen. In view of these issues, our hospital independently developed standardized formulas of neonatal PN solution, which has been approved in Australia as a patented invention. Herein, we reported the composition and application protocol of this standardized PN solution for newborns.
