Maneuver

Interventions/Control_1

The procedure is performed under total intravenous anesthesia with remimazolam and remifentanil, with the dosage adjusted to maintain a BIS score within the range of 40-60. Fentanyl 250 ug is administered concurrently as an intraoperative analgesic. The nerve block is performed prior to induction of anesthesia. In the ISB group, 20 mL (50 mg) of 0.25% levobupivacaine is administered for the ultrasound-guided ISB. At the end of the surgery, 15 mg/kg of acetaminophen is administered, with additional doses given at 6, 12, 18, and 24 hours postoperatively. If pain persists despite this, rescue analgesics are administered.
