Median effective concentration of ropivacaine for preoperative analgesia under ultrasound-guided supra-inguinal fascia Iliaca compartment block in hip fracture patients

Abstract Ultrasound-guided supra-inguinal fascia iliaca compartment block (FICB) is increasingly used for preoperative analgesia in elderly hip fracture patients. However, the median effective concentration (50% effective concentration, EC50) of ropivacaine required for supra-inguinal FICB for preop...
