Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group S1
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.
Dexmedetomidine Injection
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.
Group S2
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.
Ropivacaine and Dexmedetomidine
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.
Group C
Before anesthesia induction, an iliac fascia block was performed using 0.375% ropivacaine (30 mL) under ultrasound guidance, followed by conventional anesthesia induction. During the anesthesia maintenance phase, an equivalent volume of 0.9% sodium chloride injection was infused intravenously.
Sodium Chloride Injection
Before anesthesia induction, an iliac fascia block was performed using 0.375% ropivacaine (30 mL) under ultrasound guidance, followed by conventional anesthesia induction. During the anesthesia maintenance phase, an equivalent volume of 0.9% sodium chloride injection was infused intravenously.
