Popis:	Summary 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. This prospective study examined its ease of use and the postoperative analgesia produced by patient-controlled interscalene analgesia with ropivacaine 0.2%. Nineteen patients undergoing major shoulder surgery were studied. Interscalene brachial plexus blocks were performed using a modified Winnie technique with the insulated Tuohy needle and a nerve stimulator. After injection of ropivacaine 0.75% 30–40 ml into the plexus, a catheter was inserted. Block and catheter insertion times were recorded. All 19 patients had successful blocks and had catheters successfully threaded. Catheter infusions provided successful analgesia (visual analogue pain score
