The Influence of Stellate Ganglion Block on Myocardial Ischemia Reperfusion Arrhythmia / 中国医师杂志

Objective To determine the influence of stellate ganglion block on myocardial ischemial reperfusion arrhythmia.Methods Sixteen rabbits were divided randomly into two groups : group A(control group), group B (experimental group) was left lateral stellate ganglion blocks. Myocardial ischemia reperfusion model in vivo was carried out routinely. Blood samplies were taken from coronary sinus for the determination of neuropeptide(NPY) and noradrenaline(NE) at the following time point before LAD crossclamping , 5min, 30min after reperfusion.The occurrence of RA was measured in 1～5min during reperfusion.Results The level of plasma NPY and NE were significantly reduced at 5min, 30min after reperfusion (P
