Abstract:
Objective To compare the effects of combined lumbar plexus-sciatic nerve block and epidural anesthesia in elderly patients undergoing unilatemal total hip replacement surgery. Methods Fortytwo patients were randomly divided in two groups (each in 21 cases),combined lumbar plexus-sciatic nerve block group (group N) and epidural anesthesia group (group EA). In group N, combined lumbar plexussciatic nerve block guided by a nerve stimulator was conducted,with 1% lidocaine 15 ml and 0.5% ropivacaine 20 ml (lumbar plexus) and 1% lidocaine 5 ml and 0.5% ropivacaine 20 ml (sciatic nerve). In group EA,epidural anesthesia was achieved by injection of 0.5% ropivacaine 10-15 ml. The variations in hemodynamics, the effect of never block and adverse reactions in both groups were recorded. Results The blood pressure was decreased significantly in group EA than that in group N at 10,20,30,60 min after epidural anesthesia (P ＜0.05). There was no difference in the onset time of sensory and motor blockade between two groups (P ＞0.05),while the duration of sensory and motor blockade was longer in group N [(436.5 ± 103.3 ), ( 307.3 ± 112.4 ) min ] than those in group EA [ (305.2 ± 110.8), ( 189.3 ± 84.5 ) min ](P ＜ 0.05). There was 4 patients combined nausea and vomiting in group EA. Conclusion Combined lumbar plexus-sciatic nerve block in elderly patients undergoing unilaternal total hip replacement surgery has stable hemodynamics, longer analgesia duration and fewer adverse reactions.
