Özet
In recent years there are some case reports suggesting that bispectral index - an electroencephalography derivative- can detect cerebral hypoperfusion during cardiac surgery. To test this hypothesis juguler bulb oxyhaemoglobin saturation measurements and concomitant bispectral index recordings were made. Forty patients undergoing open heart surgery participated in this prospective clinical study. Bispectral index was monitored throughout the study in one minute intervals and values before (BISO) and 1 min after the cerebral desaturation time (BISI) were recorded. Forty two percent of the patients have experienced at least one cerebral vein desaturation (SjvO2 < 50), which has been shown to be a reliable parameter to detect cerebral hypoperfusion during cardiopulmonary bypass. Totally we recorded 51 cerebral vein desaturation periods. Bispectral index-0 was 48±4.5 and bispectral index-1 was 43.5±5 during moderate hypothermic cardiopulmonary bypass. A significant difference (p<0.001) was found between bispectral index-0 and bispectral index-1 values. We conclude that BIS can detect cerebral hypoperfusion during hypothermic cardiopulmonary bypass in adults.
