Comparative Evaluation of a New Depth of Anesthesia Index in ConView® System and the Bispectral Index during Total Intravenous Anesthesia: A Multicenter Clinical Trial

Table 6

The values of Ai and BIS from one minute after remifentanil infusion to one minute after intubation.

	Ai	BIS	Ai-BIS
R1	51.63 ± 11.48	56.35 ± 8.98	-4.72 ± 9.25
R5	51.38 ± 7.50	52.95 ± 8.60	-1.57 ± 6.25
T0	50.35 ± 8.26	48.92 ± 9.98	1.37 ± 8.73
T1	49.19 ± 8.21	46.71 ± 10.06	2.49 ± 8.48

Data are presented as mean ± SD.
R1: one minute after remifentanil infusion. R5: five minutes after remifentanil infusion. T0: the time of intubation. T1: one minute after intubation.
During the process of deepening anesthesia from R1 to T1, Ai barely changed, which was quite different from BIS (-2.15±12.25 VS -9.58±11.67, p<0.001).
