Compared to Trendelenburg (TBG) tilt <30° what was the result of Trendelenburg (TBG) tilt >30° on Bispectral index values?
Bispectral index values also gradually increased with head down tilt and TBG >30° group showed higher BIS value than TBG <30° [Table 5 and Figure 1]. Although the BIS values among two groups were statistically significant, the patients from either group didn't complain of its awareness (probably due to their anesthetic state).
