Table 3.

The comparison of hemodynamics, analgesia nociception index, bispectral index, and effect-site concentrations of propofol and remifentanil between successful and failure patients during skull pin fixation.

	Successful	Unsuccessful	P value
N	15	11
HR	71.1 ± 11.8	69 ± 13.4	0.683
MAP	97.6 ± 15.5	108.6 ± 15.8	0.101
ANIi	51.1 ± 16.9	27.2 ± 7.9	< 0.001*
BIS	44.9 ± 5.8	47.5 ± 7.4	0.359
Ce of propofol	2.4 ± 0.6	2.2 ± 0.7	0.298
Ce of remifentanil	4.5 ± 0.6	3.8 ± 0.5	0.004*

Ce indicates effect-site concentration; ANIi indicates an instantaneous value calculated as a mobile mean of ANI over 64 s of monitoring.

BIS bispectral index.
