Changes of cerebral oxygen metabolism during anesthesia in two groups (x̅ ± s)

Groups	Time	CERO2	SjvO2
Joint group (n=49)	T0	39.98±2.99	63.98±3.77
	T1	34.60±3.02*	84.49±4.88*,#
	T2	36.10±2.85*	77.79±4.30*,#
	T3	38.09±3.04*,#	74.46±3.84*,#
Etomidate group (n=49)	T0	40.04±3.20	64.40±3.02
	T1	35.49±3.33*	78.88±4.97*
	T2	35.48±3.20*	70.05±3.38*
	T3	34.44±3.82*	67.74±3.08*

Note: CERO₂: cerebral oxygen uptake rate; SjvO₂: blood oxygen saturation of internal jugular bulb. Compared with T0;

^*P<0.05.

Compared with etomidate group at the same time;
