  Purpose

It is apparent that the head of a preterm infant should not be left uncovered, however it remains unclear whether covering the head of a preterm baby with plastic wrapping is effective in preventing heat loss.

We conducted a prospective, randomised, controlled trial in very preterm infants to evaluate if a polyethylene cap prevents heat loss after delivery better than polyethylene occlusive wrapping and conventional drying. Furthermore, we assessed body temperature 1 hour after admission to Neonatal Intensive Care Unit (NICU) to evaluate whether the polyethylene cap prevents postnatal heat loss.

Primary Outcome Measures:
  • Axillary temperature taken on admission to the NICU (immediately after cap and wrap removal) and again 1 hour later. [ Time Frame: Admission to the NICU ]

Secondary Outcome Measures:
  • Mortality prior to hospital discharge, presence of major brain injury, tracheal intubation at birth, Apgar scores, delivery to admission time, blood gas analysis and serum glucose concentration on NICU admission. [ Time Frame: NICU discharge ]

Enrollment: 96
Study Start Date: December 2007
Study Completion Date: February 2009
Primary Completion Date: February 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: cap
In the cap group, the head of the infant was covered with a polyethylene cap immediately after birth
Device: Polyethylene cap
In the cap group, the head of the infant was covered with a polyethylene cap immediately after birth
Active Comparator: wrap
Infants in the wrap group were placed into the polyethylene bag, while still wet, up to their necks; only the head was dried.
Device: Polyethylene wrap
Infants in the wrap group were placed into the polyethylene bag, while still wet, up to their necks; only the head was dried.
conventional group
Infants in the control group were dried completely, according to International Guidelines for Neonatal Resuscitation.
Other: conventional treatment
Infants in the control group were dried completely, according to International Guidelines for Neonatal Resuscitation.

Detailed Description:

The primary outcome measure was axillary temperature taken on admission to the NICU (immediately after cap and wrap removal) and again 1 hour later. Axillary temperature was measured using a digital thermometer (Terumo Digital Clinical Thermometer C202, Terumo Corporation, Tokio, Japan). The occurrence of hypothermia, defined as axillary temperature less then 36.4°C, on NICU admission was also evaluated.

Secondary outcomes included mortality prior to hospital discharge, presence of major brain injury (sonographic evidence of intraventricular hemorrhage with ventricular dilatation, parenchymal hemorrhagic infarction, or periventricular leukomalacia), tracheal intubation at birth, Apgar scores, delivery to admission time, blood gas analysis and serum glucose concentration on NICU admission.
