Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Paravertebral block will be performed with either liposomal bupivacaine or plain bupivacaine. The efficacy of nerve block will be assessed every 5 minutes after local anesthetic injection. We will evaluate pain severity, opioid consumption, and occurrence of adverse events at the following timepoints, i.e., end of surgery, 30 minutes after surgery, and 2, 6, 12, 24, 36, 48, 60, and 72 hours after surgery. Additionally, occurrence of complications, quality of recovery, and subjective sleep quality will be assessed during hospital stay after surgery.
