Mini-dose Bier's block vs systemic analgesia in distal radius fractures: a promising reduction in emergency department throughput time.

This study compared the effect of the conventional technique of procedural sedation and the mini-dose intravenous regional anesthesia (IVRA). 45 patients received IVRA, and 47 received iv. ketamine. The pain score, emergency department (ED) length of stay and patients' satisfaction were compared. The study revealed that not only the levels of hemodynamic parameters but also their stability, and the patient's satisfaction in the IVRA group were significantly better. The patients' pain score and ED length of stay were also significantly decreased in those who received IVRA. Mini-dose IVRA technique contributes to better hemodynamic stability, without prominent adverse events, and leads to significant pain control and improved ED throughput time. : NCT03349216 (ClinicalTrials.gov).
