OBJECTIVES:To study the long-term effect of active parenteral nutrition support regimen in preterm infants with a gestational age of <34 weeks.
METHODS:According to the different doses of fat emulsion and amino acids used in the early stage, the preterm infants with a gestational age of <34 weeks, who were admitted to the hospital within 24 hours after birth from May to December 2019, were divided into an active parenteral nutrition group and a conventional parenteral nutrition group (n=50). Physical indices and the measurements of the Gesell Development Scale were collected at the age of 6 months and 13 months.
RESULTS:At the age of 6 months, the active parenteral nutrition group (n=46) had higher developmental quotients of gross motor, fine motor, and personal-social behavior than the conventional parenteral nutrition group (n=34) (P<0.05). At the age of 13 months, the active parenteral nutrition group (n=25) had higher developmental quotients of adaptive behavior, gross motor, and personal-social behavior than the conventional parenteral nutrition group (n=19) (P<0.05). There were no significant differences in the physical development indices such as body weight, body height, and head circumference between the two groups during follow-up (P>0.05).
CONCLUSIONS:For preterm infants with a gestational age of <34 weeks, an active parenteral nutrition support strategy with high doses of fat emulsion and amino acids within 24 hours after birth can improve their long-term neurodevelopment.
