Abstract：Objective To observe the effects of right stellate ganglion block (SGB) on rat microcirculation during extracorporeal circulation .Methods Twenty healthy SD rats were selected and randomly divided into two groups:control group(C group)and SGB group(RC group).Both C group and RC group were processed by extracor-poreal circulation for 1 h.RC group received stellate ganglion block with bupivacaine before Undergoing cardiopulmo -nary bypass .The observation points included T 0:before extracorporeal circulation;T1: after 30 min of extracorporeal circulation;T2:after 1 h of extracorporeal circulation .The observation included blood pressure , heart rate,blood gas parameters difference of oxygen pressure between artery and vein ( Pa-vO2 ) and blood lactate .Results There were significant difference in lactate , Pa-vO2 and blood pressure at different time between two groups ( P<0.05 ) .There was an interavtion effect in heart rate , lactate and Pa-vO2 between treatment and time(P<0.05).There were signifi-cant difference in the lactate and heart rate between two groups ( P<0.05 ) .Conclusion Right stellate ganglion block can improve the tissue perfusion by ameliorating rat microcirculation during extracorporeal circulation .
