Objective:To observe the clinical effect of Sufentanil combined with ropivacaine on patient controlled extradural analgesia(PCEA).Methods:Ninty patients,ASA I-II,undergoing gynecological tumor operation were randomly divided into three groups.Group A:the composition of PCEA 0.2% Ropivacaine,sufentanil 0.5 μg/ml and 5mg Haloperidol added to 100ml with normal saline.Group B:sufentanil 0.75 μg/ml,and others were same as group A.Group C:sufentanil 1.0μg/ml,others same as group A.All the subjects were carried on VAS and RSS score on postoperative instantly and 6h,12h,24h after operation with PCEA(maintenance dose 2ml/h,PCA0.5ml,interval time 15min).Results:VAS and RSS score were lower in group B and C than group A,there was significant difference(P<0.05);and no significant difference between group B and C(P>0.05).The incidence of adverse reaction in group A and B was lower than that of in group C,there was significant difference between them(P<0.05),and no significant difference between group A and B(P>0.05).Conclusion:Sufentanil can be used for PCEA securely,and the dosage of sufentanill 0.75 μg/ml is better.

目的:观察罗哌卡因复合利多卡因用于颈丛阻滞麻醉的临床效果.方法:选择ASAⅠ～Ⅱ级,拟行甲状腺腺瘤切除术患者60例,随机分为2组(A组为罗哌卡因-利多卡因合剂组,B组为布比卡因-利多卡因合剂组),行双侧颈丛阻滞(患侧深浅丛,对侧浅丛).观察麻醉起效时间、镇痛持续时间及麻醉并发症,并评价麻醉效果.结果:麻醉起效时间A组与B组相似,差异无统计学意义(P＞0.05).麻醉并发症比较两组差异也无统计学意义(P＞0.05).结论:罗哌卡因复合利多卡因用于颈丛阻滞麻醉效果确切,安全有效.
