The Effects of Systemic Steroids on the Duration of a Psoas Compartment Block.
In Brief
A Phase 4 clinical trial evaluating Dexamethasone, Bupivacaine, and 3 other interventions for Osteoarthritis, Hip. Completed, enrolled 115 participants across 1 site.
Detailed Summary
This study will investigate the ability of systemic dexamethasone to prolong the sensory block duration for lumbar plexus nerve blockade.
Study Details
Timeline
Interventions
A lumbar plexus nerve block will be performed for patients undergoing hip arthroplasty. A total of 25cc's of 0.25% bupivacaine with 1:400,000 epinephrine will be administered for postoperative analgesia. Surgical anesthesia will be provided either by an intrathecal spinal block or general anesthesia. Successful blockade will be assumed if the patient has a decrease or loss of pinprick sensation in the femoral nerve distribution, which innervates the anterior thigh. If no evidence of blockade is present, testing will occur again at 30 minutes post block. Testing will be performed with a 25 gauge Whitacre needle and once present the area of testing will be marked with a surgical marking pen so that repeat sensory testing can be undertaken at that same site over the course of the study. The subjects will then receive dexamethasone (4 or 8 mg) or placebo (saline) based on arm placement.
Bupivacaine will be used in lumbar plexus nerve block mixture.
Epinephrine will be used in lumbar plexus nerve block mixture.
This is the procedure that will be performed.
Patients randomized to the placebo group will receive normal saline intravenously.
