2. METHODS OF THE REVIEW
Infants with major congenital malformations, particularly abdominal wall defects, were excluded. "Routine thermal care" included: the delivery room temperature at a minimum of 25º C; drying of the infant immediately after birth; removing any wet blankets and wrapping the infant in a pre-warmed blanket; pre-warming any contact surfaces; avoiding draughts; and use of radiant warmers or incubators. The definitions of hypothermia were inconsistent across the studies.
