Study Arms:
- Ultrasound-guided continuous ESP block with opioid PCA (Type: EXPERIMENTAL): A high-frequency linear ultrasound transducer will be placed in a longitudinal parasagittal orientation 3 cm lateral to the T7/T8 spinous process. The patient's skin will be anesthetized with 2% lidocaine. A Contiplex Echo ultra 360 18G needle with 20G × 55 cm Contiplex Echo catheter will be inserted using an in-plane superior-to-inferior approach to place the tip into the fascial plane on the deep (anterior) aspect of erector spinae muscle. The location of the needle tip will be confirmed by visible fluid spread lifting erector spinae muscle off the bony shadow of the transverse process. A total of 30 mL of 0.375% ropivacaine with 5mcg/mL of epinephrine will be injected in 5-mL aliquots through the needle (maximum of 3mg/kg) followed by insertion of the echo catheter system under direct vision 2-3 cm beyond the needle tip.
- Ultrasound-guided sham block and catheter with opioid PCA (Type: SHAM_COMPARATOR): The exact same procedure as the experimental group will be followed, substituting saline for local anesthetic at the same amounts and rate. As with the ESP group, the patients will have PCA initiated postoperatively in the PACU at the same doses.

Based on this trial design, predict the completion outcome and termination type (if applicable).
