do the concentration and volume of local anesthetics affect the onset and success of infraclavicular anesthesia?

conclusions the volume of the injected anesthetic accelerated the onset of sensory and motor block without affecting the rate of success in our patients. results the onset of sensory and motor block was significantly shorter in the 1.3% lidocaine group than in the 2% lidocaine group (p ≤ 0.05). the success rate of sensory and motor block was not different. the quality (completeness) of sensory ...
