Abstract:   (313 Views)
Background: Distal radius fractures are one of the most common upper extremity fractures, and their incidence continues to increase due to an aging population and an increase in osteoporosis. Various methods of analgesia for distal radius fractures have been described—including hematoma blocks and nerve blocks. Hematoma blocks are a simple and effective method of providing analgesia; nonetheless, their efficacy may be limited in some cases. On the other hand, nerve blocks provide more targeted analgesia and may be more effective in reducing pain during fracture reduction.   This study aimed to compare the analgesic effectiveness of radial and median nerve blocks with hematoma blocks under ultrasound guidance in treating distal radius fractures. Also, this study aimed to compare the analgesia of radial and median nerve blocks with hematoma blocks under ultrasound guidance to reduce distal radius fractures.
   Methods: In this prospective trial, patients with distal radius fractures referring to 2 academic centers were placed into 2 randomized groups, including hematoma block, and radial median block, both of which were ultrasound-guided. The patient's pain levels were measured and recorded based on the visual analog scale before the block, 5, 10, and 15 minutes after the block, at the start of reduction, during reduction, and 5, 10, and 15 minutes after reduction. Patient satisfaction and physician satisfaction rates were assessed, and side effects were also observed for 1 week. Quantitative variables were reported as mean ± standard deviation, and number and frequency percentages were reported for qualitative variables. The Student t test and the chi-square test were used on a case-by-case basis. The significance level was set at P ˂ 0.05.
   Results: In this study, 120 patients were included. The groups had no significant differences in pain reduction during the procedure. Analgesic medication was needed during the procedure for 17 patients; nerve blocks were applied for 6 patients, and hematoma blocks for 11 patients, which was statistically significant (P = 0.041). Satisfaction rates for patients and physicians performing the procedure were significantly higher in the nerve block group than in the hematoma block group (P = 0.001; P ˂ 0.001, respectively).
   Conclusion: The results of this study suggest that ultrasound-guided radial and median nerve blocks can be used as alternative methods of analgesia with other techniques in the reduction of distal radius fractures
