Perineural Local Anesthetic Administration With a Continuous Infusion Versus Automatic Intermittent Boluses

• Status: Not yet recruiting
• Trial end date: 2022-07-01
• Target enrollment: 70
• Participant gender: All

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.

• Phase: N/A
• Accepts Healthy Volunteers?: No
