Summary
Clinical aim: Does reducing the dose of local anesthetic in ultrasound-guided axillary plexus
anesthesia have any effect on the success rate and additional parameters of block quality?
Methodology: In this prospective cohort study three groups of 40 outpatients each were
administered dosages of 1% prilocaine of either 40mL, 30mL or 20mL for axillary plexus
anesthesia. Met-Hb was measured prior to administration of the block and then hourly until
the Met-Hb concentration fell. Parameters of block quality and any adverse effects were
recorded. The level of significance was defined with α ≤ 0.05.
