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

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).
