Optimal Volume, Rate, and Interval of Bolus Nerve Catheters for Shoulder Surgery

Summary

The purpose of this study is to determine the ideal delivery of local anesthetics for pain control when using continuous interscalene peripheral nerve catheters for shoulder surgery. The study will be conducted in three stages. In the first stage the ideal bolus volume of ropivacaine will be determined. In the second stage the optimal rate of delivery of the bolus (infusion rate) will be determined. Finally, once both the ideal volume and infusion rate has been determined, the optimal interval between boluses of local anesthetic will be determined.
