These effects were the focus of this study.<\/jats:p><jats:p><jats:bold>Methods:\u2002<\/jats:bold> Twenty\u2010eight adult chronic renal failure patients (ASA physical status III) scheduled for arteriovenous fistula construction were studied in a prospective, randomized, double\u2010blind, controlled design. All axillary block procedures were performed by the same anaesthesiologist using the nerve stimulator technique. The control group received 40\u2003ml of lidocaine (10\u2003mg\u2003ml<jats:sup>\u22121<\/jats:sup>) combined with 1\u2003ml of saline, and the clonidine group received 40\u2003ml of lidocaine (10\u2003mg\u2003ml<jats:sup>\u22121<\/jats:sup>) mixed with 150\u2003\u00b5g of clonidine. Characteristics of the patients and the blocks were recorded, in addition to data on the nerves stimulated, intraoperative haemodynamic parameters, and sedative and analgesic requirements.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> The onset time for sensory blockade was longer in the clonidine group than in the controls (<jats:italic>P\u2003=\u2003<\/jats:italic>0.013), and both motor and sensory blocks lasted longer in the clonidine group (<jats:italic>P\u2003=\u2003<\/jats:italic>0.004, <jats:italic>P<\/jats:italic>\u2003&lt;\u20030.001, respectively).
