Major shoulder surgery can be extremely painful. Interscalene brachial plexus catheters provide excellent postoperative analgesia but are technically difficult to place. A new insulated Tuohy needle system for plexus catheterisation is now available. ⋯ Mean [range] catheter insertion time was 3.6 [1-10] min. Decreased block and catheter insertion times were associated with experience with the equipment when comparing the mean (SD) times for the first seven catheters and the last seven catheters inserted (12.1 (4.2) min vs. 7.9 (2.4) min), p < 0.05). It is concluded that the insulated Tuohy needle system for interscalene catheterisation proved easy to use in the hands of someone who had not used it before, and can be recommended.
