Abstract

Objective The present study compares the analgesic efficacy of two techniques to perform non-surgical reduction: fracture hematoma block and radial nerve supracondylar block.

Methods Forty patients with fractures of the distal third of the radius, who required reduction, were selected in a quasi-randomized clinical trial to receive one of the anesthetic techniques. All patients signed the informed consent form, except for those who did not wish to participate in the study, had neurological injury, had contraindication to the procedure in the emergency room, or with contraindication to the use of lidocaine. To measure analgesia, the numerical pain rate scale was used at four different moments: preblock, postblock, during reduction, and after reduction; then three differences were calculated: the first between before and after blocking; the second between during reduction and after blockade; and the third between before blocking and after reduction.

Results The fracture hematoma and supracondylar block groups showed the following mean values, respectively: 3.90 (1–10) and 3.50 (-6–10) in difference 1; 4.35 (-5–10) and 5.00 (-3–10) in difference 2; and 4.65 (1–10) and 3.80 (-3–10) in difference 3.

Conclusion Both techniques proved to be efficient for analgesia, with mild superiority of hematoma block, but without statistical significance.
