According to Fox News.com, doctors kept a U.K. baby boy 'frozen' for four days in order slow down his increasing heart rate, metro.co.uk reported.
Baby Edward Ives' heart was racing at more than 300 beats per minute, so doctors sedated him, wrapping him in a blanket filled with cooling gel – and lowered his body temperature to about 91 degrees, the newspaper reported.
Doctors told Edward's parents he had a five percent survival rate – he was born with supraventricular tachycardia and had to be delivered at 35 weeks at the University College London Hospital.
On the fourth day, Edward's heart rate returned to normal, and doctors slowly warmed him back up to 98.6 degrees.
"All I wanted to do was scoop him up and give him a warm cuddle. I just had to keep reminding myself that it was saving his life," Edward's mother, Claire, 29, told the Metro.
