The previous version of this systematic review demonstrated that
therapeutic hypothermia for term and late preterm newborn infants
with moderate or severe HIE resulted in a clinically important
reduction in the composite outcome of mortality or neurodevelopmental
disability to 18 to 24 months of age (Jacobs 2007).
This reviewupdate has added three newrandomised controlled trials
including 644 infants (TOBY Study 2009; neo.nEURO Study
2010; Zhou 2010) and has also included 204 additional infants
fromone trial (ICE Study 2011) to bring the total infants included
in the review to 1505.
