Randomized Controlled Trial Comparative Study
To what extent can local anesthetics be reduced for infraclavicular block with ultrasound guidance?
To assess the adequacy of different amounts of local anesthetics (LA) in infraclavicular blockade (ICB) under ultrasonographic (US) guidance and neurostimulation and compare them to the conventional doses under neurostimulation (NS). ⋯ The results show that US guidance is more effective in maintenance of successful ICB than neurostimulation guidance alone and a reduction of LA doses even to 70% of conventionally used doses seems possible with US guidance.
