Most researches revealed that volatile anesthetic sevoflurane has a more marked
cardioprotective effect against ischemia compared with intravenous agent propofol.However,
propofol has been suggested to be more benefit for attenuation of surgery-induced
immunosuppression.Thus, the aim of this study was to investigate under the specific OPCAB
surgical stress, the influence of 3 established anesthetic techniques: sevoflurane, propofol
and combine of sevoflurane and propofol maintained anesthesia on the apoptosis of circulating
lymphocytes.
