Perineural Local Anesthetic Administration With a Continuous Infusion Versus Automatic Intermittent Boluses
In Brief
A clinical study evaluating Continuous Infusion and Automated Intermittent Boluses for Pain, Acute and 2 related conditions. Completed, enrolled 71 participants across 1 site.
Detailed Summary
This will be a randomized comparison of continuous local anesthetic infusion with patient controlled boluses (PCA) to automated boluses with PCA for continuous popliteal sciatic nerve blocks. The goal will be to determine the relationship between method of local anesthetic administration (continuous with PCA initiated at discharge vs. intermittent dosing with PCA with a 5-hour delay) for continuous peripheral nerve block and the resulting pain control and duration of analgesia.
Study Details
Timeline
Interventions
A continuous infusion of ropivacaine 0.2% (6 mL/hr, 4 mL patient controlled bolus with 30-minute lockout) will be initiated in the recovery room.
Administration of automated intermittent boluses of ropivacaine 0.2% (8 mL every 2 hr with 4 mL patient controlled bolus with 30-minute lockout) will be initiated in the recovery room, but with a 5-hour delay for the first bolus (can be overridden by patients if they would like to initiate their perineural infusion earlier than 5 hours).
