Levobupivacaine Combined With Sufentanil For Ultrasound-guided Clinical Observation Brachial Plexus Lock

Objective: With ultrasound guidance, sufentanil combined with levobupivacaine isused to block brachial plexus and observe the effects of anesthesia and adversereactions.Methods:40cases of18-60year-old upper limb adult patients undergoing electivesurgery, ultrasound-guided blocked interscalene brachial plexus (ICBP),they wererandomly divided into two groups,every group is20cases. Group A received20ml0.375%levobupivacaine; Group B received20ml0.375%levobupivacaine+5ugsufentanil.1. To compare is onset time of anesthesia sensory and motor, maintenancetime of feeling and movement;2. To recorde is the start of anesthesia (T1), anesthesia10min (T2),30min (T3),60min (T4) heart rate(HR), systolic blood pressure(SDP),diastolic blood pressure (DBP), oxygen saturation (SPO2)and intraoperative sedationscore;3.adverse reactions was observed.Results:(1) Feeling duration of B group, compared with group A is statisticallysignificant (P <0.05), but movement duration is not statistically significan.(2) After T2, SDP, DBP, HR of B and group, compared with group A werestatistically significant (P <0.05).(3) SPO2of group A and B groups is no significant difference (P>0.05), but thesedation score significantly is higher than in group A at T2later(P <0.05).(4) Adverse reactions are not statistically significant, the group B has1cases ofnausea and vomiting, the group A has1cases of vascular punctured. Conclusion: the ultrasonic positioning ICBP can look directly at the target nerve,vascular, needle and local anesthetic spreading,it reduces the occurrence of adversereactions; feeling maintenance time can be significantly prolonged postoperativeanalgesia. Therefore, small doses of sufentanil combined with levobupivacaine inultrasound-guided brachial plexus block ICBP,it is a safe and effective anesthesia, andis superior to simple levobupivacaine.
