 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 36.4C, on NICU admission was also evaluated.
