ABSTRACT

[Purpose]To study the changes of hemodynamic response and the states of myocardial ischemia with peripheral nerve block in patients with coronary heart disease after introcoronary stent(ICS)undergoing lower-extremity surgery in order to guide the clinical application.[Methods]Peripheral nerve block was performed on 32 patients with coronary heart disease after ICS undergoing lower-extremity surgery,the SP,DP and HR were measured before anesthesia,at the beginning of incision,30 min after the incision of surgery and after completion of operation;the states of myocardial ischemia reflected by DCG were monitored before 24h of surgery,2～5h after the incision and 48h after completion of operation.[Results]The SP,DP and HR were decreased more significantly at the beginning of incision,30 min after the incision of surgery and after completion of operation than before anesthesia(P0.05).The frequency of occurences of myocardial ischemia during and after the surgery was increased significantly(P
