ABSTRACT
Objective To investigate the therapeutic efficacy and safety of stellate ganglion block (SGB) with ropivacaine to treat Renault's disease.Methods Thirty seven patients with Renault's disease were randomly assigned into two groups:the lidocainegroup (L group,18 patients) treated by SGB with 5 ml of 1％ lidocaine,and the Ropivacaine-group (R group,19 patients) treated by SGB with 5 ml of 0.2％ ropivacaine.The efficacy,adverse reactions,and the recurrence after 3 months of two groups were observed and compared.Results The total effective rate of 89.5 ％ in group R was significantly higher that 55.6％ in group L (P ＜ 0.05).There were less times(22 times) presenting no Homers'sign in group R compared to group L (43 times).The incidence of adverse reaction and the recurrence after 3 months in group R were not statistically significantly different form group L (P ＞ 0.05).Conclu-sions SGB with 0.2％ ropivacaine could obtain better efficacy compared to lidocaine,and had a higher security.
