Table 2.

Regional cerebral tissue oxygen saturations (SctO2) in different head positions averaged across 20 infants (two additional infants with severe IVH were excluded)

	NIRS channel position	Averaged SctO2 (n=20)	SD	Sig (2-tailed paired t-test)
Head turned from midline to the left	L SctO2 (head midline)	72.7	6.4	n/a
	L SctO2 (head turned left) during the 1^st 10-min epoch	71.1	6.1	0.05
	L SctO2 (head turned left) during the 2^nd 10-min epoch	71.7	4.8	0.04
	R SctO2 (head midline)	75.0	7.3	n/a
	R SctO2 (head turned left) during the 1^st 10-min epoch	74.4	7.5	0.49
	R SctO2 (head turned left) during the 2^nd 10-min epoch	75.3	6.9	0.62
Head turned from midline to the right	L SctO2 (head midline)	72.3	6.1	n/a
	L SctO2 (head turned right) during the 1^st 10-min epoch	73.1	5.3	0.19
	L SctO2 (head turned right) during the 2^nd 10-min epoch	74.2	5.5	0.13
	R SctO2 (head midline)	73.3	6.9	n/a
	R SctO2 (head turned right) during the 1^st 10-min epoch	73.8	6.8	0.58
	R SctO2 (head turned right) during the 2^nd 10-min epoch	74.3	5.6	0.73

IVH – intraventricular hemorrhage; NIRS – near-infrared spectroscopy; SctO2 – cerebral tissue oxygen saturation; SD – standard deviation; L – left side of the head (NIRS probe position); R – right side of the head
