Postoperative Analgesia by Continuous Interscalene Block of 0.2% Ropivacaine: Comparison of the Two Different Infusion Rates

Continuous interscalene block at a rate of 4-10 mL/h has been used for postoperative analgesia of upper extremities. However, with these infusion rates, sometimes local anesthetic leaks from the catheter insertion site. Therefore, lower infusion rate is preferable. The present study investigated whether a lower infusion rate (2 mL/h) of interscalene ropivacaine could be useful on postoperative analgesia of upper extremities.
