The median effective analgesic concentration (MEAC) of ropivacaine in ultrasound-guided sciatic nerve block for postoperative analgesia after ACL-R

Background: The median effective concentration of ropivacaine of ultrasound guided sciatic nerve block required for effective postoperative analgesia after arthroscopic anterior cruciate ligament reconstruction has not yet been determined. This study was to explore the median effective analgesic concentration of ropivacaine required to produce a ...

the Median Effective Analgesic Concentration (MEAC) of Ropivacaine in Ultrasound-Guided Interscalene Brachial Plexus Block for Postoperative Analgesia after Proximal Humerus Fracture: A Double-Blind up-down Concentration-Finding Study

Background: This study aimed to determine the median effective analgesic concentration of 10mL ropivacaine in interscalene brachial plexus block for postoperative anesthesia in 50% of the patients (EC50). Method: This study was conducted on 30 patients with ASA grade I or II, who are planning to undergo proximal humerus fracture operation.

The Median Effective Analgesic Concentration (MEAC) of Ropivacaine in Ultrasound-Guided Interscalene Brachial Plexus Block for Postoperative Analgesia after Arthroscopic Repair of Rotator Cuff: A Double-Blind Up-Down Concentration-Finding Study

Objectives:The median effective concentration of ropivacaine in interscalene brachial plexus block for postoperative analgesia after arthroscopic rotator cuff repair(ARCR) has not been determined. Design: this is a prospective double blinded study. Method: This study was conducted on 40 patients with ASA grade I or II who had selective ARCR.
