Objective: To evaluate the application rationality of three fixed sets of neonatal parenteral nutrition prescription in our hospital. Methods: A total of 320 neonatal parenteral nutrition prescriptions in our hospital was collected from Jan. to Jul. 2018

and 52 pediatric patients were enrolled

of which 38 cases of premature infants

14 cases of full-term infants. The components in three fixed sets of prescriptions were analyzed. Length of stay

duration of TPN use

fluid intake

calorie intake

blood sugar and liver function were statistically analyzed. The application rationality of three fixed sets of prescriptions was evaluated based on the growth and development of the children. Results: The stability of three fixed sets of prescriptions in clinical application was guaranteed

the sugar rate

heat nitrogen ratio and the concentration of electrolyte were within the rational range. However

3 out of 52 children had excessive fluid intake in the early stage

and 114 out of 320 prescriptions had insufficient calorie intake. The prescriptions of premature infants were short of electrolyte sodium and magnesium

and the prescriptions of full-term infants were short of electrolyte magnesium. Conclusion: In clinical application

the three fixed sets of prescriptions of neonatal parenteral nutrition in our hospital can basically meet the growth and development of most newborns. However

the parenteral nutrition prescription has the problems of insufficient calorie and protein intake

electrolyte sodium and magnesium intake

which still need to be further improved.
