Researchers led by a team from Imperial College London have found that babies who are starved of oxygen should be cooled to reduce their risk of brain damage.
The study involved about 300 babies and was conducted at 33 hospitals in the UK and also in five other countries.
The researchers found that babies who were cooled after suffering oxygen loss at birth were 57% more likely to survive without brain damage
"Although unfortunately it doesn't work in every case, our study showed the proportion of babies that survived without signs of brain damage went from 28% to 44% with cooling treatments - that's a 57% increase," said lead researcher Dr Denis Azzopardi, from Imperial College London.
The details of the study are published in the New England Journal of Medicine.
