Title: Clinical use of nerve stimulator located cathetering for continuous interscalene brachial plexus block
Abstract: Objectives:To study the clinical results and feasibility of continuous brachial plexus nerve block and postoperative anagesia with catheters located by nerve stimulator in interscalene approach. Methods:60 ASAⅠ~Ⅱ patients receiving continuous interscalene brachial plexus block and postoperative analgesia for forearm,wrist or hand surgery were randomized into two groups.In group I,nerve blocks were performed using a normal venous needle located with traditional method which elicites numbness of the limb. Then a epidural catheter was passed and secured. Group Ⅱ were guided by nerve stimulator and special catheters were placed. Results:Compared with group I,time to perform the block,time to block and time to obtain satisfactory sensory and motor blockade in group II were shorter(P0.05).All cases were successful in group Ⅱ. There were 3 failure cases in group Ⅰ,with the failure rate of 10%. Postoperative analgesic results were good in two groups, but better in group II(P0.05). 3 analgesic leakage and 2 catheter dislocation arised in groupⅠ.Group Ⅱ had less intraoperative sedative usage and postoperative analgesics and local aneasthetics usage(P0.05). 4 cases of hematoma and 4 cases of nerve injury occured in group I while no complication occured in group Ⅱ.Conclusions:Nerve stimulator-guided catheters for continuous brachial plexus nerve block and postoperative anagesia have a higher success rate, more accurate results,and less adverse reactions.
