Background: The treatment of postoperative pain after arthroscopy of the hip is a challenge and there are no known studies related to its treatment which have been based on regional block. Objectives:To determine the behaviour of postoperative pain and the satisfaction of the patients who have been treated with arthroscopy of the hip with femoral block, lumbar plexus block or intra-articular infiltration. Methods:All the anaesthetic records of 61 patients that required arthroscopy of the hip under general anaesthesia using femoral block with 0,3 mL/kg of Levobupivacaine 0,375 %, lumbar plexus block with 0,4 mL/kg of Levobupivacaine 0,375 % or intra-articular infiltration with 20 mL of Bupivacaine 0,5 % were checked. The data about postoperative pain which had been assessed with visual analogous scale at the 15, 30, 60 and 120 minutes and at the 24 hours, the satisfaction of the patients at the moment of the discharge from hospital at the 24 hours, the sensitive and motor block and the need to use Morphine in the postoperative phase were also checked. Results:The group of patients that were treated with intra-articular infiltration presented the highest levels of pain in almost all evaluated moments. As compared with the lumbar plexus block, more patients that underwent femoral block presented higher levels of pain in almost all moments. Out of the patients in the group that was treated with intra-articular infiltration, the 55 % received Morphine at any postoperative moment as well as the 28,5 % treated with femoral block and the 15 % who underwent lumbar plexus block. The level of patients´ satisfaction was high and similar in the three groups. Conclusions:Postoperative analgesia for arthroscopy of the hip was better with lumbar plexus block as compared with femoral block or intra-articular infiltration.

Keywords : lumbar plexus block; femoral block; intra-articular infiltration; arthroscopy of the hip.
