University of Oklahoma
Mean axillary temperatures, taken during NICU resuscitation upon admission to the NICU, will not differ between VLBW babies who are occlusively wrapped and very low birth weight (VLBW) babies who are placed on thermal warming blankets.

Primary Outcome Measures:
  • Neonatal Intensive Care Unit (NICU) Admission Temperature [ Time Frame: At time of admission to the NICU - usually within 10-15 min of birth ]

Enrollment: 36
Study Start Date: May 2007
Study Completion Date: November 2008
Primary Completion Date: November 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Blanket
This arm includes those Extremely low gestational age newborns (ELGANs) who are to be placed on a sodium acetate warming blanket after delivery.
Device: InfaTherm
A gel blanket containing a sodium acetate-based medium that, when activated, becomes exothermic and provides heat.
Experimental: Wrap
This arm includes those ELGANs randomized to be wrapped in polyethylene after delivery.
Device: NeoWrap
This is a polyethylene wrap that will be placed around the ELGAN from the neck down to prevent heat loss.

Ages Eligible for Study:   24 Weeks to 28 Weeks   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Participants in this study will be selected from the inborn population at University Hospital. Eligible patients will be selected from the group of babies with estimated gestational ages of 24-28 weeks and <1250g.

Exclusion Criteria:

  • Congenital anomalies with open lesions such as meningomyelocele, or omphaloceles
  • Blistering skin conditions
  • Resuscitation not performed secondary to infant being below limits of viability as assessed by the in-house attending physician (specifically, according to current NRP recommendations):

    • Where gestation, birth weight, and/or congenital anomalies are associated with almost certain early death, and unacceptably high morbidity is likely among the rare survivors, resuscitation is not indicated. Exceptions may be made based on parental desires.

      • Newborns with confirmed gestation age of less than 24 weeks or birth weight less than 400 grams
      • Anencephaly
      • Confirmed Trisomy 13 or Trisomy 18 syndrome
      • Meconium staining of amniotic fluid
      • Birth assessment of gestational age > 28 weeks or >1250 grams
      • Maternal temp >38 degrees C around the time of delivery.
