The Study Of Relationship Between Nutrition Support Status And Growth Velocity And EUGR In Preterm Infants

Objective To provide valuable reference basis and make more reasonable nutrition supports,we Are going to discuss about various nutrients intake and the correlation of nutrients with the growth velocity different and the influencing factors of EUGR in preterm infants.Method We retrospectively reviewed the clinical records of gestational age<37 weeks premature in 775cases from October 2012 to September 2015 in the NICU in Xinhua hospital affiliated to Shanghai Jiao Tong university.We recorded the data in the perinatal period of each cases of premature infants,weight increase or decrease in the hospitalization period,enteral and parenteral nutrition actual intake,related complications and biochemical indicators,etc.Results In these 773 cases of premature infants,almost 98.3%babies used parenteral nutrition.Their birth weight were around 2500 g and their gestational age were around 33weeks.They got more nutritions including energy,fat,protein,vitamin D,calcium and iron day by day in every birth weight preterm infants.Group NBW and LBW can take more than 80%from enteral nutrition by the 2~ndd week and the 4~thh week after birth.Group VLBW and ELBW still needed nutrition support by parenteral nutrition at their 4~thh week after birth.Especially the nutrition intake in Group ELBW still needed 50%from parenteral nutrition.The growth velocity in each group of preterm infants increased with time,and the lower birth weight group would get more weight gain.The growth velocity in group ELBW,their can get around 18.8(5.1 32.4)g/kg/d at the 4~thh week after birth.But most of the preterm infants can’t get the recommend growth velocity.In this study,we use the standard(2013 Fenton curve)to evaluate the weight at day 14(EUGR-14),day 28(EUGR-28)and the day of discharge were 43%,58.2%and 47.5%,respectively.Compared with the studies in previous years,EUGR in this study got relatively improved,but didn’t decrease much.The reason maybe was related to the loss of energy,fat,vitamin D,calcium and iron from enteral and parenteral nutrition.Conclusion We should be aware of the importance of reasonable nutrition interventions of the premature infants within 28 days after the birth.Let the preterm infants get enough nutritions from enteral and parenteral as soon as possible.If the nutritions meet the guideline,that would make the growth velocity reach standard of intrauterine growth.That could reduce the occurrence of EUGR.
