ABSTRACT
Objective To compare the effects of two different parenteral nutrition solutions on nutritional status of premature infants,such as the early physical,serum prealbumin,retinol binding protein and albumin.Methods We collected 61 cases of premature infants in neonatal intensive care unit of the Third Military Medical University Xinqiao Hospital,which were divided into 2 groups of traditional parenteral nutrition (TTPN) and early parenteral nutrition (ETPN).Group TTPN geted 6％ paediatric compound amino acid 0.5 g/(kg·d) at24 hours after birth,daily increasing 0.25 ～0.5 g/(kg·d),up to 3.0 g/(kg·d).The 20％ long-chain fat emulsion 0.5 g/(kg ·d) was applied at 3 days after birth,daily increasing 0.25 ～ 0.5 g/(kg·d),up to 3.0 g/(kg·d).Group ETPN get 6％ paediatric compound amino acid 1 g/(kg·d) at 12 ～24 hours after birth,daily increasing 0.5 g/(kg·d),up to 3.0 ～ 0.5 g/(kg· d).The 20％ long-chain fat emulsion 0.5 ～ 1.0 g/(kg·d) was applied after 24 hours after birth,daily increasing 0.5 g/(kg· d),up to 3.0 g/(kg· d).We calculate calorie and amino acid intake of the two groups,and compared the weight,length,head circumference growth,serum prealbumin,retinol-binding protein and albumin levels of the two groups.Results The amino acid and total caloric intake of Group ETPN were significantly higher than those of Group TTPN (P ＜ 0.05).No statistical differences in the albumin,prealbumin,and retinol binding protein level of the two groups at birth (P ＞ 0.05).However,the prealbumin and retinol-binding protein level of group ETPN significantly higher than those of Group TTPN (P ＜ 0.05) at 7 days after birth.Conclusion Early parenteral nutrition in early life can effectively improve physical growth and nutrient metabolism status of premature infants.Prealbumin and retinol-binding protein are sensitive to evaluate the protein nutritional status in premature infants.
