Clinical Trial Summary

An alternative to improve the quality of postoperative analgesia is to use various perineural adjuvants applicable to peripheral nerve block along with local anesthetics to increase the analgesic effect. Dexamethasone is a strong and long-acting corticosteroid, which reduces postoperative nausea and vomiting and increases the duration of nerve blockade. Most of the existing clinical studies compared the analgesic effect with the placebo group after adding an adjuvant in a single shot nerve block, and there were very few cases of comparing the analgesic effect with the placebo group after adding the adjuvant in peripheral nerve block through continuous catheter infusion. Therefore, we designed this study to investigate whether the use of dexamethasone as a peripheral adjuvant for continuous femoral nerve block has a better pain and recovery profile.

Outcome

Type Measure Description Time frame Safety issue
Primary Maximum Numeric rating scale pain score at movement Pain intensity at movement will be evaluated by an 11-point numeric rating scale (NRS: 0 = no pain, 10 = worst imaginable pain) postoperative 1 hour, postoperative 6 hours, postoperative day 1, postoperative day 2. Maximum Numeric rating scale pain score was determined based on highest score among repeated assessment of surgical site pain severity postoperatively. within postoperative day 2
Secondary Numeric rating scale pain score at rest Pain intensity at rest will be evaluated by an 11-point numeric rating scale (NRS: 0 = no pain, 10 = worst imaginable pain) postoperative 1 hour, postoperative 6 hours, postoperative day 1, postoperative day 2. up to postoperative day 2
Secondary Numeric rating scale pain score at movement Pain intensity during 45-degree passive flexion of the hip with the ipsilateral knee flexed naturally will be evaluated by an 11-point numeric rating scale (NRS: 0 = no pain, 10 = worst imaginable pain) postoperative 1 hour, postoperative 6 hours, postoperative day 1, postoperative day 2. up to postoperative day 2
Secondary Postoperative opioid consumption morphine equivalent dose up to postoperative day 2
