0.1% Ropivacaine
An initial bolus of 0.1% ropivacaine , with a total volume of 10 mL (containing 10 mg ropivacaine), was administered to the first patient. For subsequent patients, the dose was adjusted in increments or decrements of 2 mL (2 mg 0.1% ropivacaine), based on whether a visual analogue scale pain score of less than 3 was achieved within 30 minutes after administration.
