RESUMO
Objective:To analyze the effect of MCT/LCT fat emulsions at different doses on the growth and development of prema-ture and low birth weight infants. Methods: Totally 76 cases of preterm or low birth weight infants were divided into the treatment group (40 cases) and the control group (36 cases), both groups were given MCT/LCT fat emulsions, amino acid and glucose injec-tions in 12-24 h after the birth. The initial dose of MCT/LCT fat emulsions in the treatment group was 2. 0 g·kg-1 ·d-1 and the dose was gradually increased to 3. 0 g·kg-1 ·d-1 with 0. 5 g·kg-1 ·d-1 progressive increase. The initial dose of MCT/LCT fat emulsions in the control group was 0. 5 g·kg-1 ·d-1 , and the dose was increased to 3. 0 g·kg-1 ·d-1 with 0. 5 g·kg-1 ·d-1 progressive in-crease. The treatment course was 7 days. The neonatal weight, serum total bilirubin, direct bilirubin, alanine aminotransferase, total cholesterol, triacylglycerol and blood glucose were monitored in the two groups. Results:The born body mass recovery time of the ob-servation group was (4. 38+0. 93) d, which was significantly shorter than that in the control group [(6. 81+1. 90) d]. After the re-covery, the body weight growth rate of the observation group was (30. 41+1. 81) g·kg-1 ·d-1 , which was significantly higher than that of the control group [(18. 21 +2. 08) g·kg-1 ·d-1, P 0. 05). Conclusion:Early application of MCT/LCT fat emul-sions at high dose is beneficial to the improvement of nutritional status in premature infants.
