The effects of increasing the maximum prescribed volume of 50 ml lidocaine 1% to 65 ml in a combined sciatic 3-in-1 block were investigated in 25 adult patients. The goal of the study was (1) to show possible increase in the success rate and (2) to determine if toxic plasma levels of local anaesthetic would be reached. Further more, we wanted to find out if there were any side-effects. ⋯ There were no statistical differences between the three groups. CONCLUSION. Increasing the dosage of lidocaine from 500 to 650 mg makes the block very successful without any toxic side-effects.

Case ReportsSelective block of nerves in the axillary approach to the brachial plexus.
Optimal surgical conditions for flexor tendon tenolysis in the hand were achieved by ulnar, radial, and musculocutaneous nerve block at the axilla combined with median nerve block at the wrist. ⋯ Palpation of nerves together with a nerve stimulator were used to localize the nerves accurately.

A study of 25 patients was carried out to determine the efficacy of interscalene block (ISB) for the treatment of chronic upper extremity pain. An RSD score was used to categorize these patients. Seventeen of the 25 patients had less pain after ISB, and 14 also had increased range of motion of the affected limb. ⋯ ISB was compared with stellate ganglion block (SGB) in patients undergoing both treatments. ISB seemed to be at least as effective as SGB for treatment of RSD/causalgia and may have some advantages over SGB. The role of somatic and sympathetic blockade is discussed.
