Experimental: r-PVB
Participants in this arm will receive Revised-Paravertebral Nerve Block (r-PVB) after induction of general anesthesia and before the start of surgery.
|
Revised-Paravertebral Nerve Block (r-PVB) is performed after induction of general anesthesia and before the start of surgery.
Under ultrasound guidance, an intercostal space between the 7th and 9th ribs at the midaxillary line is identified.
Using an in-plane technique, the needle is advanced into the internal intercostal muscle, and 30 mL of 0.5% ropivacaine is injected to achieve the block.

Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
Mean QoR-15 score on postoperative days 1 and 2
Zeitfenster: Postoperative day 1 and postoperative day 2
|
Quality of recovery will be assessed using the 15-item Quality of Recovery questionnaire (QoR-15), ranging from 0 (the worst) to 150 (the best).
The primary recovery outcome is the mean QoR-15 score measured on postoperative day 1 and postoperative day 2.
|
Postoperative day 1 and postoperative day 2
|
|
Mean postoperative NRS pain score during the first 2 postoperative days
Zeitfenster: From discharge from the post-anesthesia care unit through postoperative day 2.
|
Postoperative pain will be assessed using theNumeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst pain the patient can imagine).
The primary pain outcome is the mean of eight postoperative NRS pain scores assessed upon discharge from the post-anesthesia care unit; on the evening of surgery between 7:00 PM and 9:00 PM; and on postoperative days 1 and 2, in the morning between 6:00 AM and 10:00 AM, at midday between 12:00 PM and 3:00 PM, and in the evening between 7:00 PM and 9:00 PM.

Postoperative day 1 and postoperative day 2
|
|
Resting and movement NRS pain scores on postoperative days 1 and 2
Zeitfenster: Postoperative day 1 and postoperative day 2
