When focusing on only infants with increased CL ΔO 2 Hb, a trend was seen in the ΔO 2 Hb response being higher in FGR compared to AGA infants, but failed to reach statistical significance (47.38 ± 16.09 vs. 31.94 ± 23.11 μM.cm, p = 0.09). ΔTHb is an important measure of cerebral blood volume and indicates cerebral vasoreactivity ( 20 , 21 ), where a reduced ΔTHb is indicative of cerebral vasoconstriction in response to the heel lance.

Moreover, the proportion of infants with no-response in CL ΔTHb was higher in FGR (6/20) compared to AGA (1/15) group, but did not reach statistical significance ( p = 0.098, Table 2 ).
