"All patients will be anesthetized with PNBs for surgery.~* PNBs will be performed in a block room at least 30minute preoperatively.~* All PNBs will be performed under ultrasound guidance (LOGIQ P6, GE Healthcare; Chicago, IL) using a high-frequency linear transducer (3.4-10.8MHz).~* All blocks will be performed after skin preparation with 2% chlorhexidine gluconate by 1 orthopedic surgeon (YUP) with vast experience in ultrasound-guided nerve block techniques.~* A 22-ga Tuohy needle will be introduced in-plane and 2 to 3mL of saline will be used to confirm the correct position of the needle tip near the target nerve.~* The study medication will be administered through the needle as a bolus of 20mL of a 1:1 mixed solution of bupivacaine 0.75% and lidocaine 1%.~* The total volume per every block will be 20 ml in the form of bupivacaine 1.25% with 1:200,000 epinephrine and 250 mg Mgso4."
