Anesthésie Locorégionale dans un Pays à Ressources Limitées: La Lidocaïne 1,5% Adrenalinée, Alternative à la Ropivacaine 0,5% Pour le Bloc Axillaire Échoguidé

OBJECTIVE: The aim of this study was to evaluate lidocaine 1.5% adrenaline as an alternative to ropivacaine 0.5% for the echo guided axillary block. METHODE: We conducted a 28-month prospective and randomized study (January 15, 2017 to May 15, 2019) conducted in the anesthesia department of the Ignace Deen National Hospital in Conakry, Guinea. RESULTS: A total of 38 patients were enrolled: 19 in each group. Their average age was 46 ± 17 years in the lidocaine group compared to 44 ± 20 years in the ropivacaine group. The average time to fix the block in the lidocaine group was 6.8 ± 2.1 minutes compared to 8.3 ± 2.4 minutes in the ropivacaine group (p = 0.04). The average duration of action was 233 ± 57 minutes in the lidocaine group versus 260 ± 74 minutes in the ropivacaine group (p= 0.21). The block efficiency rate was identical in both groups with 89.5% of effective blocks in the lidocaine group and in the ropivacaine group (p =1). The cost of consumables for the lidocaine group was 15 euros compared to 60 euros for the ropivacaine group. CONCLUSION: 1.5% adrenaline lidocaine is a good alternative to ropivacaine 0.5% for the production of echoguided axillary blocks in resource-limited countries.
