Effects of Acute Bleeding Followed by Hydroxyethyl Starch 130/0.4 or a Crystalloid on Propofol Concentrations, Cerebral Oxygenation, and Electroencephalographic and Haemodynamic Variables in Pigs

Table 3

Suppression ratio (SR: %), total power ( : μV), spectral edge frequency (SEF: Hz), bispectral index (BIS), approximate entropy (AE), permutation entropy (PE), SR corrected SEF (SRSEF: Hz), and SR corrected PE (SRPE) at each study phase: A: right before the start of bleeding; B: in the end of bleeding/start of the waiting period; C: in the end of the waiting period/start of the volume replacement period); D: in the end of the volume replacement period/start of the final phase; and E: in the end of the study. GLR: group that received lactated Ringer’s for volume replacement; GHES: group that received hydroxyethyl starch for volume replacement. Mean ± standard deviation is shown. The number of animals ( ) in each group for each parameter is shown.
