Abstract:
Objective To assess the enteral iron and energy intake of premature neonates during hospitalization in neonatal intensive care unit(NICU).Methods This retrospective study enrolled 208 premature neonates admitted in the NICU of Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine within 48 hours after birth from January 2012 to December 2013.The following data were recorded for all infants:clinical basic information,the amount of formula iron intake in milk,enteral and parenteral nutrition intake as well as oral iron supplementation.Results The amount of enteral iron intake in the 1st,2nd,3rd,4th week after birth and at discharge was (0.2 ± 0.3) mg/(kg · d),(0.9 ±0.7) mg/(kg · d),(1.2 ±1.0) mg/(kg · d),(1.5 ± 1.1) mg/(kg · d),and (2.2 ± 1.1) mg/(kg · d),respectively,which accounted for 10％,45 ％,60％,75 ％ and 110％ of the recommended iron intake.The energy intake in the 1st,2nd,3rd,4th week after birth and at discharge was (13.2 ± 14.8) kcal/(kg · d) (1 kcal =4.184 kJ),(46.0 ± 32.6) kcal/(kg · d),(62.2 ± 38.1) kcal/(kg · d),(71.3 ± 38.2) kca]/(kg · d) and (105.3 ± 32.1) kcal/(kg · d),which accounted for 11.0％,38.3％,51.8％,59.4％ and 87.8％ of the recommended intake,respectively.Lower enteral iron and energy intake after birth occurred in the premature infants with lower birth weight,especially those with anemia who had significantly lower enteral iron intake than the normal neonates in the first 2 weeks after birth.Conclusions Enteral iron and energy intake among premature neonates were insufficient,especially during the first 2 weeks after birth.It is necessary to develop and implement more effective nutritional support to improve the nutritional status of premature infants.
