Not Applicable

Terminated

• Conditions: Hypertriglyceridemia; Hyperglycemia
• Interventions: Drug: Intravenous Fat Emulsions

• Registration Number: NCT01096446
• Lead Sponsor: OSF Healthcare System

Brief Summary

The purpose of this study is to study the tolerances of Extremely Low Birthweight Infants who are born at less than 750 grams who are started at a higher infusion rate of intravenous lipid emulsions (2 gm/kg/day). These infants will be compared with a control group who are at the standard lipid emulsion infusion rate (0.5 gm/kg/day).

A. Objectives of this project.

Null Hypothesis: There will not be a significant difference for Extremely Low Birth Weight Infants (ELBW) \<750 grams being able to tolerate a higher infusion rate of Intravenous Fat Emulsions (IVFE) within the first days of life (days 1-7) as evidenced by maintenance of a serum triglyceride level of 200 mg/dl or less.

Alternative Hypothesis: There will be a significant difference (p\<0.05) for Extremely Low Birth Weight Infants (ELBW) \<750 grams being able to tolerate a higher infusion rate of Intravenous Fat Emulsions (IVFE) within the first days of life (days 1-7) as evidenced by maintenance of a serum triglyceride level of 200 mg/dl or less.

Detailed Description

ELBW infants will be randomized into either the control group or the experimental group.

The control group will receive standardized care which consists of receiving TPN within 24 to 36 hours of life. The control group will be given the standardized dosage of IVFE starting at 0.5 grams/kg/day in the TPN and have IVFE advanced daily by 0.5 grams/kg/day until a goal rate of 3 grams/kg/day is achieved. The experimental group will receive TPN within 24 to 36 hours of life. For these infants, IVFE will begin at 2 grams/kg/day. For the experimental group, Intralipid will be increased by 0.5 grams/kg/day until a goal rate of 3 grams/kg/day is achieved.

An informed consent form (Appendix A), to be signed by the parent or guardian, will be obtained for all infants before they are enrolled into this study. Assent waiver is requested on the study participants because they are infants.

All infants enrolled in this study will have their laboratory data monitored at least daily during the first week of life. A baseline triglyceride will be drawn prior to beginning TPN to verify that their serum triglyceride levels are \<200 gm/dl. This will include a daily lipid profile panel used to evaluate the serum triglyceride levels and the tolerance of the two different IVFE infusion rates. Lipid tolerance will be defined as infants having a serum triglyceride levels at \< 200 mg/dl. Lipid intolerance will be defined as infants having a serum triglyceride of 201 mg/dl or greater. If lipid intolerance occurs, IVFE will be decreased by the following standard of care:

Serum Triglycerides Levels Changes Intralipid in TPN by:

150-200 mg/dl Keep at current IVFE order 201-249 mg/dl decrease by 1 grams/kg/day 250-299 mg/dl decrease by 1.5 gram/kg/day 300 mg/dl or greater Reduce Intralipid to 0.5 grams/kg/day to prevent essential fatty acid deficiency (EFAD). If hypertriglyceridemia persists (300 mg/dlor greater) over 24 hours keep IVFE at 0.5 gm/kg/day to prevent EFAD.

The total caloric intake will be calculated and collected daily for both groups. The calorie intake will be specified as total kilocalories per kilogram (kcal/kg/day). The goal calorie intake for both groups will be 90 kcal/kg/day. The kcal/kg index will be calculated by a Registered Dietitian, who is assigned to the Neonatal Intensive Care Unit.

All collected data will be presented as a mean +/- SD. The statistical significance will be defined by a p value \< 0.05.

Arm && Interventions

Group	Intervention	Description
Standard Infusion	Intravenous Fat Emulsions	Infants randomized into the control group will receive 0.5 gm/kg/day of Intravenous Fat Emulsions (IVFE) on their first day of total parenteral nutrition (TPN). The IVFE will be increased by 0.5 gm/kg/day daily until a goal reached of 3 gm/kg/day of IVFE in the TPN.
Higher Infusion	Intravenous Fat Emulsions	Infants randomized into the experimental group will receive 2 gm/kg/day of Intravenous Fat Emulsions (IVFE) on their first day of total parenteral nutrition (TPN). The IVFE will be increased by 0.5 gm/kg/day daily until a goal reached of 3 gm/kg/day of IVFE in the TPN.

Primary Outcome Measures

Name	Time	Method
Number of Infants Serum Triglyceride Level Higher Than 200 mg/dl	First 7 days of life	Each day the infants have a serum triglyceride level drawn to assess their tolerance of the intravenous fat emulsion being given.

Secondary Outcome Measures

Name	Time	Method
Regain Birthweight	First 2 weeks of life	Infants in both groups weights were monitored to determine if giving higher infusions of intravenous fat emulsion helped the infants regain their birthweight sooner.
Infants Will Achieve 90 Calories/Kilogram/Day	First 14 days of Life	Monitored the calorie intake of infants to see which group was able to acheive 90 cal/kg/day from the total parenteral nutrition.
Maintain Appropriate for Gestational Age Status at Discharge	Entire hospital stay	Recorded all infant's weights at discharge and plotted the anthropometric values on the Fenton Growth Charts.
Initiation of Glucose	First 7 days of life	Infants were monitored to see if insulin was started to control hyperglycemia.
