Interventions
Before anesthesia induction, an iliac fascia block was administered using 0.375% ropivacaine (30 mL) under ultrasound guidance, followed by conventional anesthesia induction. During the anesthesia maintenance phase, dexmedetomidine was infused intravenously at a rate of 0.5 µg/kg/h.
Before anesthesia induction, an iliac fascia block was administered using a mixture of 0.375% ropivacaine and 1ug/kg dexmedetomidine (30ml) under ultrasound guidance. During the anesthesia maintenance phase, an equivalent volume of 0.9% sodium chloride injection was infused intravenously.
