Axillary plexus block with etidocaine.

Axillary plexus block has been used to compare 0.5% and 1.0% etidocaine (with adrenaline 5 mug/ml) in 32 patients in an open label study. The injected volume was 30 ml. The time to total analgesia and motor block was around 10-12 minutes. Complete block was achieved in more than 97% of cases. The duration of total analgesia and motor block was 6-7 hours. The time from injection to return of total sensation and motility was 8.5-10 hours. Adequate analgesia was achieved in all patients but two (one in each group). No noteworthy differences were found between the two solutions.
