Evolution of Apparent Diffusion Coefficient and Fractional Anisotropy in the Cerebrum of Asphyxiated Newborns Treated with Hypothermia over the First Month of Life

Table 1

Clinical characteristics of the asphyxiated newborns treated with hypothermia.

Variables	All patients ()
Gestational age (weeks), mean ± SD	39.21 ± 1.52
Birth weight (g), mean ± SD	3402 ± 703
Sex
Male, (%)	34 (56)
Female, (%)	27 (44)
Arterial cord pH, mean ± SD	6.98 ± 0.20
Initial postnatal blood gas pH, mean ± SD	7.04 ± 0.16
Initial modified Sarnat score
Score 1 (mild)	10 (16)
Score 2 (moderate)	41 (67)
Score 3 (severe)	10 (16)
Initiation of hypothermia (hours), mean ± SD	5.22 ± 1.30

The ten newborns with initial modified Sarnat score of 1 were cooled because their initial background pattern on amplitude-integrated electroencephalogram showed moderate encephalopathy.
