OBJECTIVES: To compare the quality and the duration of @entity1337 produced by a supraclavicular brachial plexus blockade obtained with a mixture of @entity3303 and @entity1341 when supplemented or not with @entity681 . STUDY DESIGN: Prospective, randomized, double-blind study. @entity1 : The study included 40 @entity1 undergoing osteosynthesis of the upper limb under brachial plexus block, randomly assigned to two groups. METHODS: The @entity1 of the control group were given 0.5% @entity1341 1 mg.kg-1 and 1% @entity3303 2 mg.kg-1. Those of the @entity681 group, received the same mixture supplemented with @entity681 0.2 mg.kg-1. During the postoperative period, the characteristics of @entity1337 were blindly evaluated every hour for 48 h with a visual analogic scale graduated from 0 to 100. @entity1337 was considered satisfactory when the score was below 30. Adverse effects of opiates (drowsiness, @entity111 , @entity1209 ) were also assessed. @entity26 saturation was continuously monitored. Blood pressure, heart and respiratory rates were measured at the same intervals than @entity1337 . Duration of @entity1337 are expressed as medians (range) and compared using a Mann and Whitney's U test. RESULTS: The respective durations of satisfactory @entity1337 were significantly different: 12.5 h (8-17) in the control group versus 24 h (8-48) for the @entity681 group. The adverse effects in the @entity681 group were @entity390 (2), @entity391 (1) and @entity111 (1). No @entity1576 was noted. CONCLUSION: @entity681 added to a mixture of @entity3303 and @entity1341 increases twofold the duration of @entity86 following branchial plexus blockade.
