An Effect Compared Study Of Brachial Plexus Block With Nerve Stimulator Locating

Object:1.To compare the different effect of brachial plexus nerve block anesthesia byepidural catheter was inserted or no epidural catheter in the interscalene with the Borgreatmethod.2. Observating influence of the effect anesthesia when reducing anesthetic capacityon interscalene brachial plexus block.Method:135patients of the interscalene brachial plexus nerve block in our hospital inFebruary2012to October2012.In accordance with the method of block randomizedgrouping,135patients operated the upper limb were randomly divided into A group (nonecatheter), B (20ml, catheter), C group (15ml, catheter). Record the time for completing theoperation and the onset of sensory nerve block and motor nerve block were measured; Recordtime that sensory nerve and motor nerve were blocked completedly and analgesia was rated asexcellent, effective, poor and failure. Observe and record complications of analgesia.Result:Group A completed the operation need the time (2.98±0.94) min was significantlyshorter than the group B (5.23±1.24)min (P<0.01) and the group C(5.33±0.96) min (P<0.01);Time of the group B and the group C needed to complete the operation was no statisticallysignificant (P﹥0.05); Sensory block onset time of group A (6.88±1.70)min were longer thanthe group B (5.07±1.18) min)(P<0.01) and the group C (5.73±1.56) min (P<0.01), sensoryblock onset time of the group B was shorter than group C,comparing two groups wasstatistically significant difference (P<0.05); The time of motor nerve block working time ofgroup A (6.71±1.16) min were longer than group B (5.33±1.45)min (P<0.01) and the group C(5.67±1.28) min (P<0.05), the group B motor nerve block working time compared with thegroup C, there was no statistically significant difference (P﹥0.05); The time of feel nervewas completed block in the Group B (12.18±3.48) min was shorter than group A (13.67±3.03)min (P<0.05) and the group C (13.58±2.94) min(P<0.05), sensory nerve blockade completelyof the group A and group B there was no statistically significant difference (P﹥0.05); thetime of motor nerve block perfect time of A, B, C there was no statistically significantdifference (P﹥0.05).Conclusion: This study shows, the operation time of the group A is shorter than the group B’sand group C’s, but anesthesia superior rate in the group B and the group C are significantlyhigher than in the group the group A. Anesthesia effect will be more perfect, anesthesia failurerate is lower, dosage of local anesthetics is less in the group B and group C.
