Does intra-venous pain pump or continuous infraclavicular brachial block prevent the rebound pain of brachial plexus blockade after distal radius fracture fixation?: A prospective randomized control trial

At postoperative 9 hours, the pain VAS score was significantly higher in the BPB only group than in the IV PCA group (p = 0.007) and continuous block group (p = 0.009). At postoperative 12 hours, the pain VAS score was significantly higher in the BPB only group than in the continuous block group (p = 0.004). The total opioid equivalent consumption (OEC) was significantly higher in the IV PCA group than in the BPB only group and continuous block group (p < 0.001, respectively); however, it was not significantly different between the BPB only group and continuous block group (p = 0.713). Continuous infraclavicular BPB is effective for controlling rebound pain after DRF fixation under BPB without increasing opioid consumption.
