Preterm newborns typically must be thermally regulated. In the United States, isolettes (incubators) are used to help them maintain their temperature. Traditionally, the temperature support (i.e. the temperature of the incubator) is decreased slowly according to NICU protocol until the baby is able to maintain its temperature in an open crib, without regard to the status of its feedings. This study will attempt to determine if there is a difference in length of stay, weight gain, and calories needed to gain appropriate weight between a group of newborns whose isolette temperatures are decreased in an aggressive strategy (isolette temperatures are decreased based only on baby's body temperature), and a group of newborns whose isolette temperatures are decreased in a conservative strategy (isolette temperatures are decreased to a minimum temperature and then kept steady until their feeds are at caloric goal and they are taking at least half of their feeds by mouth).

Condition Intervention
Premature Neonates
Other: Conservative weaning
Other: Aggressive Weaning

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Effect of Conservative Weaning of Thermoregulatory Support on Weight Gain and Length of Stay in Preterm Neonates

Further study details as provided by University of Missouri-Columbia:

Primary Outcome Measures:
  • Length of hospital stay [ Time Frame: Hospital discharge ]

Secondary Outcome Measures:
  • Weight gain [ Time Frame: When patient is on 120 cal/kg/day dietary intake ]
  • Caloric requirement [ Time Frame: When patient is changed to oral ad lib demand feeds ]

Enrollment: 0
Study Start Date: January 2009
Estimated Study Completion Date: November 2009
Estimated Primary Completion Date: November 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Aggressive Weaning
Infants will be weaned from the isolette using our current NICU standard of care.
Other: Aggressive Weaning
Infants will be weaned from the isolette based solely on their temperature without regard to feed status (current standard of care in our NICU)
Experimental: Conservative Weaning
Infants will be weaned from the isolette using a modified conservative weaning schedule.
Other: Conservative weaning
Infants will not be weaned from the isolette until their feeds are at full calorie goal (120 kcal/kg/day) and at least half of feeds are taken orally.
