Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The researchers are trying to determine pain medication consumption in the first 24 hours after surgery in patients given the standard continuous infusion of local anesthetic versus patients given the same total dose via programmed intermittent dosing. Both groups will receive the option of patient controlled pain medication as well as the same dose of pre-programmed pain medication. The only difference is the rate of administration: continuous vs. hourly intervals.
