Introduction: The benefit of adding dexamethasone in regional anesthesia has recently been the focus of investigation as clinical reports suggest improved block characteristics. The aim of this study is to evaluate whether perineural administration of dexamethasone is more effective in prolonging the duration of lumbar plexus block than giving it systemically.

 

Methods: 60 (out of 72) patients were recruited to undergo arthroscopic knee surgery using lumbar plexus block. These patients were divided randomly into 3 groups, 20 patients in each; group L (combined lumbar plexus and sciatic nerve block with bupivacaine 0.5%), group D (combined lumbar plexus and sciatic nerve block with perineural bupivacaine 0.5%+ 8mg dexamethasone in LPB ) & group S(combined lumbar plexus and sciatic nerve block with bupivacaine0.5% +8mg intravenous dexamethasone.

 

Statistical analysis: SPSS statistics v.17.0 for windows was used. Data was summarized and analyzed. The results were reported as mean ± SD. Comparison of the means of the 3 study groups was done using the ANOVA test. Non parametric variables were compared using Kruskal Wallis test.

 

Conclusion: Both perineural and IV administration of dexamethasone improve the efficacy of lumbar plexus block by prolonging the duration of analgesia, enhancing onset action of local anesthetics, and reducing postoperative analgesic requirements without increasing the incidence of complications.
