罗哌卡因复合舒芬太尼在肌间沟臂丛神经阻滞中的临床观察

目的探讨罗哌卡因复合舒芬太尼用于肌间沟臂丛神经阻滞的临床效果。方法将70例20-65岁行臂丛神经阻滞麻醉的上肢手术患者随机分为两组。对照组：1%罗哌卡因15ml＋0.9%氯化钠注射液15ml;观察组：1%罗哌卡因15ml＋舒芬太尼10μg（1ml）＋0.9%氯化钠注射液14ml。比较麻醉后两组患者麻醉起效时间、镇静程度、感觉及运动阻滞持续时间及镇痛作用时间。结果两组麻醉起效时间无统计学意义,感觉阻滞持续时间、运动阻滞持续时间、镇痛作用时间差异有统计学意义（P〈0.05）。注药后10-30min时观察组镇静效果较对照组更明显,镇静评分差异有统计学意义（P〈0.05）。结论罗哌卡因复合舒芬太尼用于臂丛神经阻滞麻醉,作用持续时间较长,镇静效果较好,不良反应少,可减少静脉镇痛镇静药的用量,提高镇痛效果。

Clinical Observation of the Effect of ropivacaine and sufentanil on interscalene brachial plexus block

Objective To study the clinical effect of ropivacaine and sufentanil on interscalene brachial plexus block.Methods 70 patients aged 20 to 65 undergoing upper limb surgery receiving brachial plexus block anesthesia were randomly divided into control group and observation group.Control group received 15ml ropivacaine 1% and 15ml sodium chloride injection 0.9%.Observation group received 15ml ropivacaine 1%,1ml sufentanil 10μg and 14ml sodium chloride injection 0.9%.Compare patients of two groups after anesthesia with the onset time of anesthesia,the depth of sedation,the duration of sensation and motor block,and the duration of analgesic action.Results The onset time of anesthesia of two groups has no statistical significance.The duration of sensation and motor block,and the duration of analgesic action have statistical significance（P 0.05）.After injection 10-30min,sedative effect of observation group was better than that of control group,sedation score has statistical significance（P 0.05）.Conclusion Ropivacaine and sufentanil used in brachial plexus block anesthesia makes relief duration longer,sedative effect better,adverse reaction less,and can reduce the dosage of vein analgesics sedatives and improve analgesic effect.
