Randomized Controlled Trial Evaluating Postoperative Analgesia and Muscle Strength Between Single Versus Continuous Adductor Canal Block for Ambulatory ACL Reconstruction.
In Brief
A clinical study evaluating Mepivacaine, adductor canal continuous nerve catheter, and 5 other interventions for Rupture of Anterior Cruciate Ligament and Tear of Anterior Cruciate Ligament. Completed, enrolled 59 participants across 1 site.
Detailed Summary
Despite the apparent multifaceted benefit in differentiating blockade sites and duration of nerve blockade, the efficacy of continuous adductor canal blockade utilized specifically in ACL reconstruction has not been extensively studied. This study will test the hypothesis that the use of the adductor canal continuous nerve catheter will result in lower subjective pain scores on postoperative day 2 and improved quadriceps strength on postoperative day 1.
Study Details
Timeline
Interventions
20cc of 2% mepivacaine \<20 minutes prior to in room time.
Placement of ultrasound guided adductor canal continuous nerve catheter
normal saline as bolus for placement, followed by initiation of 1/8% bupivacaine infusion through adductor canal catheter at 8cc/h
ultrasound guided adductor canal nerve block
10cc of 0.5% ropivacaine + 2 mg dexamethasone (0. 5cc), keeping total injectate at 10.5cc to spare significant proximal spread to femoral nerve
Anesthesia induction will include a propofol bolus.
Intraoperative opioid should be limited to no more than 150mcg of fentanyl.
