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.
