Abstract
Background: Despite increasingly wider use, there remains controversy among anesthesiologists regarding preferred formulations and the role of steroid adjuvants in regional anesthesia. There is also uncertainty in the role of dexamethasone when administered directly versus peripherally. We hypothesize that directly mixing dexamethasone into the regional nerve block rather than peripherally administered intravenous dexamethasone will demonstrate a difference in efficacy concerning duration and rebound pain, decreased postoperative pain scores, or opioid consumption within the short-term postoperative period.
Methods: A prospective, randomized controlled blinded study was conducted for patients undergoing open reduction and internal fixation with a volar plate technique for distal radius fractures. Patients were randomized for their preoperative anesthesia. One group had ultrasound-guided supraclavicular block with ropivacaine with a direct mix of dexamethasone 4 mg (Direct group), while the other group had ultrasound-guided supraclavicular block with ropivacaine and peripheral intravenous dexamethasone 4 mg (Indirect group). Data was collected pre, intra, and postoperatively.
Results: Fifty patients consented and participated in the study, with 27 participants in the direct group and 23 participants in the indirect group. Compared to intravenous administration, directly administered dexamethasone demonstrated a significant difference in the average time for the block to fade, onset of motor and sensory recovery, and block resolution.
Conclusion: Our findings prove that directly mixing dexamethasone compared to peripherally administered intravenous dexamethasone will demonstrate a difference in efficacy with regards to duration and rebound pain, but do not prove that there will be a difference in decreased postoperative pain scores or opioid consumption within the 24-hour postoperative period.
