Although the results are few and should be considered as preliminary, the following conclusions may be drawn: 1. Etidocaine 0.5% and bupivacaine 0.5%, both with adrenaline (5 mug/ml), are comparable with regard to duration of sensory block. 2. Etidocaine 0.5% without adrenaline did not give the same duration of complete sensory block as when adrenaline was present. 3. Etidocaine 0.5% acts as a vasodilator at the site of injection. Adrenaline added to the solution counteracts the dilating effect. 4. Blood level studies of etidocaine do not at present show differences when 0.5% solution with or without adrenaline is used.
