Abstract:
Objective To evaluate the effect of dexamethasone on lumbar plexus combined sciatic nerve block (CLPSNB). Methods Sixty patients were randomly allocated into three groups with 20 cases each. Guided by a nerve stimulator,CLPSNB was performed with 0. 5% ropivacaine 45 ml plus dexametbasone 10 mg in group A,0. 5% ropivacaine 45 ml plus normal saline(NS) 2 ml and dexametbasone 10 rng Ⅳ. in group B,or 0. 5% ropivacaine 45 ml plus NS 2 ml in group C. ResultsThe durations of sensory and motor blockade in group A were [(15. 2 ± 3. 3)h and (12. 6 ± 2. 8)h], respectively, which were significantly longer than [(10. 1 ± 2. 1)h and (7. 9 ± 1.6)h]in group B and [(10. 4±2. 5)h and (7. 6±2. 3)hi in group C(P<0. 05). Conclusion Dexarnetbasone added to 0. 5% ropivacaine significantly prolonges CLPSNB.
